    • TUFF är ett verktyg för strategisk planering av tågrörelser och resursomlopp (f.n. lok). Det unika med TUFF är inte att kunna utföra dessa planeringar var för sig, utan att de kan samverka. Detta är möjligt dels genom att de ingående komponenterna kan hantera vagare data, t.ex. tidsintervall i stället för fasta tider vilket är det vanliga annars bland kommersiella lösningar, dels att det finns en samordningsfunktion, som vi kallar samordningsagent, som samordnar olika planer från olika planeringsfunktioner. Denna samordnare är programmerbar via ett speciellt språk, så att ett stort problem kan splittras upp i mindre delar, och resultat från olika planeringar av dessa delar kan sedan kombineras och nya resultat genereras. Tanken med denna integrering av olika planeringsfunktioner är att åstadkomma globalt bättre lösningar, jämfört med när varje problem löses var för sig, genom att ta hänsyn till varje planeringsproblems krav tidigt i planeringscykeln.

  • Role of platelet-derived growth factor in mesangium development and vasculopathies: lessons from platelet-derived growth factor and platelet-derived growth factor receptor mutations in mice.
  • 2004

    • PURPOSE OF REVIEW: The phenotypic consequences of null mutations in the platelet-derived growth factor-B and the platelet-derived growth factor beta-receptor genes in mice have demonstrated that these proteins play pivotal roles in the development of the vascular smooth muscle cell lineage, including pericytes and mesangial cells. RECENT FINDINGS: The lethality of these mutants has precluded analysis of the physiological and pathophysiological consequences of platelet-derived growth factor-B and platelet-derived growth factor beta-receptor deficiency in adults. This review summarizes and discusses recent data from certain tissue-specific and subtle mutations in the platelet-derived growth factor-B and platelet-derived growth factor beta-receptor genes that are compatible with postnatal viability in spite of severe developmental deficits in pericyte and mesangial cell recruitment. In the postnatal period, the animals studied developed a characteristic set of pathological changes to small blood vessels of the retina and the kidney glomerulus, which sheds light on the importance of pericytes and mesangial cells for vascular integrity and function after birth. SUMMARY: These microvascular abnormalities and their consequences bear a resemblance to diabetic microangiopathy and nephropathy. The platelet-derived growth factor-B and platelet-derived growth factor beta-receptor mutant mouse models, therefore, might serve as valuable tools in the dissection of some of the pathogenic events in diabetic microangiopathy.

  • Endothelial PDGF-B retention is required for proper investment of pericytes in the microvessel wall.
  • 2003
  • Ingår i: Genes & development. - : Cold Spring Harbor Laboratory. - 0890-9369 .- 1549-5477. ; 17:15, s. 1835-40
  • Tidskriftsartikel (refereegranskat)abstract
    • Several platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) family members display C-terminal protein motifs that confer retention of the secreted factors within the pericellular space. To address the role of PDGF-B retention in vivo, we deleted the retention motif by gene targeting in mice. This resulted in defective investment of pericytes in the microvessel wall and delayed formation of the renal glomerulus mesangium. Long-term effects of lack of PDGF-B retention included severe retinal deterioration, glomerulosclerosis, and proteinuria. We conclude that retention of PDGF-B in microvessels is essential for proper recruitment and organization of pericytes and for renal and retinal function in adult mice.

  • Learning orthopaedics : assessing medical students' experiences of interprofessional training in an orthopaedic clinical education ward.
  • 2007
  • Ingår i: J Interprof Care. - : Informa UK Limited. - 1356-1820 .- 1469-9567. ; 21:4, s. 413-23

    • Interprofessional training is becoming commonplace in undergraduate medical education. Orthopaedics is considered to be a setting that offers good opportunities for interprofessional training. Curriculum overload is a common problem, which has to be addressed with respect to content. The aim of this study was to assess medical students' experiences of interprofessional care during their orthopaedic training. Over a two-week period, medical, nursing, physiotherapy and occupational therapy students trained together in teams in an orthopaedic ward (Clinical Education Ward, CEW). A questionnaire was distributed to assess the impact of this new curriculum on medical students. A patient-satisfaction questionnaire was also administered to assess patients' satisfaction with the treatment provided by students at the CEW. In general, the medical students were satisfied with the interprofessional course in the CEW. Of the 178 medical students who took the course, 134 (75%) responded to the questionnaire. Total time devoted to orthopaedics was reported to be between 7 - 44% (mean). The total time regarding medical tasks was reported to be between 57 - 71% (mean). Results from the patient-satisfaction questionnaire showed that patients perceived CEW as highly satisfactory. The medical students reported generally satisfactory experiences of interprofessional orthopaedic training in general. In an interprofessional training context, professional supervision and role modeling takes on added importance, and may be regarded as essential ingredients in helping students to learn effectively within an authentic clinical setting.

  • Defective N-sulfation of heparan sulfate proteoglycans limits PDGF-BB binding and pericyte recruitment in vascular development
  • 2007
  • Ingår i: GENES & DEVELOPMENT. - : Cold Spring Harbor Laboratory. - 0890-9369 .- 1549-5477. ; 21:3, s. 316-331
  • Tidskriftsartikel (refereegranskat)abstract
    • During vascular development, endothelial platelet-derived growth factor B (PDGF-B) is critical for pericyte recruitment. Deletion of the conserved C-terminal heparin-binding motif impairs PDGF-BB retention and pericyte recruitment in vivo, suggesting a potential role for heparan sulfate (HS) in PDGF-BB function during vascular development. We studied the participation of HS chains in pericyte recruitment using two mouse models with altered HS biosynthesis. Reduction of N-sulfation due to deficiency in N-deacetylase/N-sulfotransferase-1 attenuated PDGF-BB binding in vitro, and led to pericyte detachment and delayed pericyte migration in vivo. Reduced N-sulfation also impaired PDGF-BB signaling and directed cell migration, but not proliferation. In contrast, HS from glucuronyl C5-epimerase mutants, which is extensively N- and 6-O-sulfated, but lacks 2-O-sulfated L-iduronic acid residues, retained PDGF-BB in vitro, and pericyte recruitment in vivo was only transiently delayed. These observations were supported by in vitro characterization of the structural features in HS important for PDGF-BB binding. We conclude that pericyte recruitment requires HS with sufficiently extended and appropriately spaced N-sulfated domains to retain PDGF-BB and activate PDGF receptor β (PDGFRβ) signaling, whereas the detailed sequence of monosaccharide and sulfate residues does not appear to be important for this interaction.

  • Common variants in breast cancer risk loci predispose to distinct tumor subtypes
  • 2022
  • Ingår i: Breast Cancer Research. - : Springer Nature. - 1465-5411 .- 1465-542X. ; 24:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundGenome-wide association studies (GWAS) have identified multiple common breast cancer susceptibility variants. Many of these variants have differential associations by estrogen receptor (ER) status, but how these variants relate with other tumor features and intrinsic molecular subtypes is unclear.MethodsAmong 106,571 invasive breast cancer cases and 95,762 controls of European ancestry with data on 173 breast cancer variants identified in previous GWAS, we used novel two-stage polytomous logistic regression models to evaluate variants in relation to multiple tumor features (ER, progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2) and grade) adjusting for each other, and to intrinsic-like subtypes.ResultsEighty-five of 173 variants were associated with at least one tumor feature (false discovery rate < 5%), most commonly ER and grade, followed by PR and HER2. Models for intrinsic-like subtypes found nearly all of these variants (83 of 85) associated at p < 0.05 with risk for at least one luminal-like subtype, and approximately half (41 of 85) of the variants were associated with risk of at least one non-luminal subtype, including 32 variants associated with triple-negative (TN) disease. Ten variants were associated with risk of all subtypes in different magnitude. Five variants were associated with risk of luminal A-like and TN subtypes in opposite directions.ConclusionThis report demonstrates a high level of complexity in the etiology heterogeneity of breast cancer susceptibility variants and can inform investigations of subtype-specific risk prediction.

  • Anarkosyndikalismens återkomst i Spanien : SACs samarbete med CNT under övergången från diktatur till demokrati
  • 2014. - 1
  • Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
    • Ett av de mest spektakulära inslagen i den spanska demokratiseringsprocess, som inleddes i samband med Francos död 1975, var den anarkosyndikalistiska fackföreningsrörelsen CNTs återkomst i legaliteten. Efter närmare 40 år av diktatur betraktades CNT av många som uträknat. Att hundratusentals människor samlades i rörelsens gamla högborg Barcelona för att bevista CNTs återkomst kom därför som en chock för det spanska etablissemanget. Det föreföll nu som att CNT var på väg att återta sin forna roll som en av de stora drivande krafterna i det spanska samhället.En av orsakerna till att det svenska SAC kom att spela en liten men inte obetydlig roll i denna process var att SAC under denna tid var CNTs viktigaste internationella samarbetspartner. Att SAC, till skillnad från CNT, aldrig varit olagligförklarat hade inneburit att SAC haft möjlighet att bygga upp ekonomiska resurser med vilka man alltsedan 1930-talet kunnat ge ett välbehövligt stöd till CNT.Här publiceras en utskrift från ett vittnesseminarium där tre av SACs tidigare internationella sekreterare berättar om sina erfarenheter från denna dramatiska tid. Seminariet behandlade SACs relationer med CNT men kom också att handla om fackföreningsrörelsen, exilrörelser, demokratiseringsprocesser och inte minst om den politiska och sociala situationen i Spanien från inbördeskriget och fram till idag.

  • Common breast cancer susceptibility alleles and the risk of breast cancer for BRCA1 and BRCA2 mutation carriers : Implications for risk prediction
  • 2010
  • Ingår i: Cancer Research. - : American Association for Cancer Research. - 0008-5472 .- 1538-7445. ; 70:23, s. 9742-9754
  • Tidskriftsartikel (refereegranskat)abstract
    • The known breast cancer susceptibility polymorphisms in FGFR2, TNRC9/TOX3, MAP3K1, LSP1, and 2q35 confer increased risks of breast cancer for BRCA1 or BRCA2 mutation carriers. We evaluated the associations of 3 additional single nucleotide polymorphisms (SNPs), rs4973768 in SLC4A7/NEK10, rs6504950 in STXBP4/COX11, and rs10941679 at 5p12, and reanalyzed the previous associations using additional carriers in a sample of 12,525 BRCA1 and 7,409 BRCA2 carriers. Additionally, we investigated potential interactions between SNPs and assessed the implications for risk prediction. The minor alleles of rs4973768 and rs10941679 were associated with increased breast cancer risk for BRCA2 carriers (per-allele HR = 1.10, 95% CI: 1.03-1.18, P = 0.006 and HR = 1.09, 95% CI: 1.01-1.19, P = 0.03, respectively). Neither SNP was associated with breast cancer risk for BRCA1 carriers, and rs6504950 was not associated with breast cancer for either BRCA1 or BRCA2 carriers. Of the 9 polymorphisms investigated, 7 were associated with breast cancer for BRCA2 carriers (FGFR2, TOX3, MAP3K1, LSP1, 2q35, SLC4A7, 5p12, P = 7 × 10-11 - 0.03), but only TOX3 and 2q35 were associated with the risk for BRCA1 carriers (P = 0.0049, 0.03, respectively). All risk-associated polymorphisms appear to interact multiplicatively on breast cancer risk for mutation carriers. Based on the joint genotype distribution of the 7 risk-associated SNPs in BRCA2 mutation carriers, the 5% of BRCA2 carriers at highest risk (i.e., between 95th and 100th percentiles) were predicted to have a probability between 80% and 96% of developing breast cancer by age 80, compared with 42% to 50% for the 5% of carriers at lowest risk. Our findings indicated that these risk differences might be sufficient to influence the clinical management of mutation carriers.

  • Program för att förebygga psykisk ohälsa hos barn : En systematisk litteraturöversikt
  • 2010
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Det är angeläget att finna metoder för att förebygga psykisk ohälsa hos barn. Det finns tecken på att psykisk ohälsa hos barn kan ha ökat under de senaste decennierna och strukturerade insatser för att komma till rätta med problemen blir allt vanligare såväl inom kommunal verksamhet som inom hälso- och sjukvård. Interventionen utgörs av så kallade program som är standardiserade och finns beskrivna i manual eller motsvarande. Här sammanfattas det vetenskapliga underlaget för två typer av program: dels de som främst syftar till att förebygga utagerande beteenden hos barn och ungdomar, dels de som i första hand syftar till att förebygga inåtvända problem som ångest, depression och självskadebeteende. Program som har en allmänt hälsobefrämjande effekt, t ex för att förebygga drogmissbruk och våldshandlingar ingår följaktligen inte. Programmen är avsedda att ha effekt, inte bara direkt efter att programmet har avslutats utan även i framtiden. Rapporten har tagits fram på förfrågan av Kungliga Vetenskapsakademien och UPP-centrum (Utvecklingscentrum för barns psykiska hälsa) vid Socialstyrelsen. Båda har efterfrågat en systematisk litteraturöversikt för att klarlägga nyttan med att använda program för att förebygga psykisk ohälsa hos barn. Slutsatser: - Av 33 bedömda standardiserade och strukturerade insatser (program) som syftar till att förebygga psykisk ohälsa hos barn har sju ett begränsat vetenskapligt stöd i den internationella litteraturen. Det är föräldrastödsprogrammen Incredible Years och Triple P, familjestödsprogrammet Family Check-Up samt skolprogrammen Good Behavior Game, Coping Power, Coping with Stress och FRIENDS. Effekterna är med få undantag små. Studierna är utförda i andra länder. Eftersom effekterna sannolikt varierar med sociala och kulturella sammanhang är det oklart i vilken utsträckning som programmen kan överföras till Sverige med bibehållen effekt. Programmen kan också behöva anpassas så att de överensstämmer med svenska värderingar och syn på barns rätt. - I Sverige används ett hundratal olika program för att förebygga psykisk ohälsa hos barn, i huvudsak av utagerande typ. Inget av dem har utvärderats i Sverige i randomiserade studier med minst sex månaders uppföljning. Programmen De otroliga åren (översatt från Incredible Years), Triple P och Family Check-Up har enligt internationella studier begränsat vetenskapligt stöd för förebyggande effekt. Programmen KOMET, COPE, SET, StegVis, Beardslees familjeintervention, Connect och DISA har undersökts i minst en kontrollerad studie vardera men har inte tillräckligt vetenskapligt stöd för förebyggande effekt. Övriga program som används i Sverige är inte vetenskapligt utprövade som preventionsprogram. - Program som bygger på att ungdomar med utagerande problem träffas i grupp kan öka risken för normbrytande beteenden. Andra negativa effekter för såväl program för utagerande som för inåtvända problem är tänkbara men ofullständigt belysta. - Det behövs randomiserade studier som undersöker om de program som används har förebyggande effekt i svenska populationer och inte medför risker. Det behövs också hälsoekonomiska studier som undersöker om programmen är kostnadseffektiva.

  • Tick-borne encephalitis virus sequenced directly from questing and blood-feeding ticks reveals quasispecies variance.
  • 2014
  • Ingår i: PLOS ONE. - San Francisco, USA : Public Library of Science (PLoS). - 1932-6203. ; 9:7
  • Tidskriftsartikel (refereegranskat)abstract
    • The increased distribution of the tick-borne encephalitis virus (TBEV) in Scandinavia highlights the importance of characterizing novel sequences within the natural foci. In this study, two TBEV strains: the Norwegian Mandal 2009 (questing nymphs pool) and the Swedish Saringe 2009 (blood-fed nymph) were sequenced and phylogenetically characterized. Interestingly, the sequence of Mandal 2009 revealed the shorter form of the TBEV genome, similar to the highly virulent Hypr strain, within the 3' non-coding region (3'NCR). A different genomic structure was found in the 3'NCR of Saringe 2009, as in-depth analysis demonstrated TBEV variants with different lengths within the poly(A) tract. This shows that TBEV quasispecies exists in nature and indicates a putative shift in the quasispecies pool when the virus switches between invertebrate and vertebrate environments. This prompted us to further sequence and analyze the 3'NCRs of additional Scandinavian TBEV strains and control strains, Hypr and Neudoerfl. Toro 2003 and Habo 2011 contained mainly a short (A)3C(A)6 poly(A) tract. A similar pattern was observed for the human TBEV isolates 1993/783 and 1991/4944; however, one clone of 1991/4944 contained an (A)3C(A)11 poly(A) sequence, demonstrating that quasispecies with longer poly(A) could be present in human isolates. Neudoerfl has previously been reported to contain a poly(A) region, but to our surprise the re-sequenced genome contained two major quasispecies variants, both lacking the poly(A) tract. We speculate that the observed differences are important factors for the understanding of virulence, spread, and control of the TBEV.

    • Most breast cancer heritability is unexplained. We hypothesized that analysis of unrelated familial cases in a GWAS context could enable the identification of novel susceptibility loci. In order to examine the association of a haplotype with breast cancer risk, we performed a genome-wide haplotype association study using a sliding window analysis of window sizes 1–25 SNPs in 650 familial invasive breast cancer cases and 5021 controls. We identified five novel risk loci on 9p24.3 (OR 3.4; p 4.9 × 10−11), 11q22.3 (OR 2.4; p 5.2 × 10−9), 15q11.2 (OR 3.6; p 2.3 × 10−8), 16q24.1 (OR 3; p 3 × 10−8) and Xq21.31 (OR 3.3; p 1.7 × 10−8) and confirmed three well-known loci on 10q25.13, 11q13.3, and 16q12.1. In total, 1593 significant risk haplotypes and 39 risk SNPs were distributed on the eight loci. In comparison with unselected breast cancer cases from a previous study, the OR was increased in the familial analysis in all eight loci. Analyzing familial cancer cases and controls enabled the identification of novel breast cancer susceptibility loci.

    • Background: The heritability of breast cancer is partly explained but much of the genetic contribution remains to be identified. Haplotypes are often used as markers of ethnicity as they are preserved through generations. We have previously demonstrated that haplotype analysis, in addition to standard SNP association studies, could give novel and more detailed information on genetic cancer susceptibility.Methods: In order to examine the association of a SNP or a haplotype to breast cancer risk, we performed a genome wide haplotype association study, using sliding window analysis of window sizes 1-25 and 50 SNPs, in 3200 Swedish breast cancer cases and 5021 controls.Results: We identified a novel breast cancer susceptibility locus in 8p21.1 (OR 2.08; p 3.92 x 10(-8)), confirmed three known loci in 10q26.13, 11q13.3, 16q12.1-2 and further identified novel subloci within these three loci. Altogether 76 risk SNPs, 3302 risk haplotypes of window size 2-25 and 113 risk haplotypes of window size 50 at p < 5 x 10(-8) on chromosomes 8, 10, 11 and 16 were identified. In the known loci haplotype analysis reached an OR of 1.48 in overall breast cancer and in familial cases OR 1.68.Conclusions: Analyzing haplotypes, rather than single variants, could detect novel susceptibility loci even in small study populations but the method requires a fairly homogenous study population.

  • Tidskriftsartikel (refereegranskat)abstract
    • Most soft x-ray microscopes operating in the water window (lambda = 2.3 - 4.4 nm) rely on synchrotron radiation sources. In the future we believe scientists will use soft x-ray microscopes as one imaging tool among others in their own laboratory. For this purpose we have developed a full field soft x-ray microscope with a laser-plasma source compact enough to fit on an optical table. In this contribution we describe the current status of this microscope now featuring stable operation at lambda = 3.37 nm or lambda = 2.48 nm. In-house fabricated single element zone plates offering the possibility to perform phase contrast imaging have been implemented. We also report on the first application experiments for compact soft x-ray microscopy, including results from studies of clay minerals and colloids existing in nature and results from phase optics experiments. Planned upgrades of the microscope include increasing the source brightness, implementing more efficient condenser optics, and installing a cryo sample stage for tomography. These improvements will open up for further applications, especially in the field of biological imaging.

  • Muntlighetsprincipen : En rättsvetenskaplig studie av processuella handläggningsformer i svensk rätt
  • 2006
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • This doctoral thesis examines the different forms of procedural communication available to the Swedish courts. The choice traditionally stood between oral and written procedure. Today the procedure in the general courts is dominated by the principle of orality, while in the administrative courts, procedure chiefly takes the written form. This being said, the types of communication procedures used in courts today are constantly changing, the reason being, in part, the advent and advancement of new communication tools such as telephone, video and the internet.The cardinal aspiration for this doctoral thesis has been to prepare a generous substructure that will allow an assessment of how the principles that constitute the foundation for the choice of a form of procedural communication stand up against the arrival of new conditions. In attaining this goal the thesis takes stock of, structure, and evaluate the current knowledge of the regulation of the forms of procedural communication and the arguments that have been put forward regarding its design and application.The chosen method is a rhetorical-topical audit of the arguments provided by the legislative community. In addition it examines the relationship between these arguments and the activities of the courts and includes a comparative analysis of the current and historic conditions of the procedural communication forms.In the thesis nine different principle topoi (argument sources) for the analysed argumentation are identified and discussed: The Purpose of the Proceedings, Security, Speed, Cost-effectiveness, the European Convention on Human Rights and Fundamental Freedoms, the Decision-making, the Parties, Publicity and the Rules and Regulations.

  • Identification of four novel susceptibility loci for oestrogen receptor negative breast cancer

  • Tidskriftsartikel (refereegranskat)abstract
    • Common variants in 94 loci have been associated with breast cancer including 15 loci with genome-wide significant associations (P<5 x 10(-8)) with oestrogen receptor (ER)-negative breast cancer and BRCA1-associated breast cancer risk. In this study, to identify new ER-negative susceptibility loci, we performed a meta-analysis of 11 genome-wide association studies (GWAS) consisting of 4,939 ER-negative cases and 14,352 controls, combined with 7,333 ER-negative cases and 42,468 controls and 15,252 BRCA1 mutation carriers genotyped on the iCOGS array. We identify four previously unidentified loci including two loci at 13q22 near KLF5, a 2p23.2 locus near WDR43 and a 2q33 locus near PPIL3 that display genome-wide significant associations with ER-negative breast cancer. In addition, 19 known breast cancer risk loci have genome-wide significant associations and 40 had moderate associations (P<0.05) with ER-negative disease. Using functional and eQTL studies we implicate TRMT61B and WDR43 at 2p23.2 and PPIL3 at 2q33 in ER-negative breast cancer aetiology. All ER-negative loci combined account for similar to 11% of familial relative risk for ER-negative disease and may contribute to improved ER-negative and BRCA1 breast cancer risk prediction.

    • Some patients with a uni- or bilateral hand- or forearm amputation cannot use a hand prosthesis, although high-tech prostheses have been developed. A hand transplantation, particularly for those with bilateral amputations, may be an alternative solution. In a hand-transplanted patient, grip function, strength, sensibility and subsequent improved quality of life can be restored. Risks related to immunosuppression must be balanced by expected benefits, and thorough selection of patients has to be performed from both medical and psychological point of view. Therefore, a national network has been established in Sweden to achieve coordination with the needed competence.

  • Physical activity, sedentary time and breast cancer risk : a Mendelian randomisation study
  • 2022
  • Ingår i: British Journal of Sports Medicine. - : BMJ Publishing Group Ltd. - 0306-3674 .- 1473-0480. ; 56:20, s. 1157-1170
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: Physical inactivity and sedentary behaviour are associated with higher breast cancer risk in observational studies, but ascribing causality is difficult. Mendelian randomisation (MR) assesses causality by simulating randomised trial groups using genotype. We assessed whether lifelong physical activity or sedentary time, assessed using genotype, may be causally associated with breast cancer risk overall, pre/post-menopause, and by case-groups defined by tumour characteristics.METHODS: We performed two-sample inverse-variance-weighted MR using individual-level Breast Cancer Association Consortium case-control data from 130 957 European-ancestry women (69 838 invasive cases), and published UK Biobank data (n=91 105-377 234). Genetic instruments were single nucleotide polymorphisms (SNPs) associated in UK Biobank with wrist-worn accelerometer-measured overall physical activity (nsnps=5) or sedentary time (nsnps=6), or accelerometer-measured (nsnps=1) or self-reported (nsnps=5) vigorous physical activity.RESULTS: Greater genetically-predicted overall activity was associated with lower breast cancer overall risk (OR=0.59; 95% confidence interval (CI) 0.42 to 0.83 per-standard deviation (SD;~8 milligravities acceleration)) and for most case-groups. Genetically-predicted vigorous activity was associated with lower risk of pre/perimenopausal breast cancer (OR=0.62; 95% CI 0.45 to 0.87,≥3 vs. 0 self-reported days/week), with consistent estimates for most case-groups. Greater genetically-predicted sedentary time was associated with higher hormone-receptor-negative tumour risk (OR=1.77; 95% CI 1.07 to 2.92 per-SD (~7% time spent sedentary)), with elevated estimates for most case-groups. Results were robust to sensitivity analyses examining pleiotropy (including weighted-median-MR, MR-Egger).CONCLUSION: Our study provides strong evidence that greater overall physical activity, greater vigorous activity, and lower sedentary time are likely to reduce breast cancer risk. More widespread adoption of active lifestyles may reduce the burden from the most common cancer in women.

  • Extended phylogeny and a revised generic classification of the Pannariaceae (Peltigerales, Ascomycota)
  • 2014
  • Ingår i: The Lichenologist. - 0024-2829 .- 1096-1135. ; 46:5, s. 627-656
  • Tidskriftsartikel (refereegranskat)abstract
    • We estimated phylogeny in the lichen-forming ascomycete family Pannariaceae. We specifically modelled spatial (across-site) heterogeneity in nucleotide frequencies, as models not incorporating this heterogeneity were found to be inadequate for our data. Model adequacy was measured here as the ability of the model to reconstruct nucleotide diversity per site in the original sequence data. A potential non-orthologue in the internal transcribed spacer region (ITS) of Degelia plumbea was observed. We propose a revised generic classification for the Pannariaceae, accepting 30 genera, based on our phylogeny, previously published phylogenies, as well as available morphological and chemical data. Four genera are established as new: Austroparmeliella (for the 'Parmeliella' lacerata group), Nebularia (for the 'Parmeliella' incrassata group), Nevesia (for 'Fuscopannaria' sampaiana), and Pectenia (for the 'Degelia' plumbea group). Two genera are reduced to synonymy, Moelleropsis (included in Fuscopannaria) and Santessoniella (non-monophyletic; type included in Psoroma). Lepidocollema, described as monotypic, is expanded to include 23 species, most of which have been treated in the 'Parmeliella' mariana group. Homothecium and Leightoniella, previously treated in the Collemataceae, are here referred to the Pannariaceae. We propose 41 new species-level combinations in the newly described and re-circumscribed genera mentioned above, as well as in Leciophysma and Psoroma.

  • A network analysis to identify mediators of germline-driven differences in breast cancer prognosis
  • 2020
  • Ingår i: Nature Communications. - : NATURE PUBLISHING GROUP. - 2041-1723. ; 11:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Identifying the underlying genetic drivers of the heritability of breast cancer prognosis remains elusive. We adapt a network-based approach to handle underpowered complex datasets to provide new insights into the potential function of germline variants in breast cancer prognosis. This network-based analysis studies similar to 7.3 million variants in 84,457 breast cancer patients in relation to breast cancer survival and confirms the results on 12,381 independent patients. Aggregating the prognostic effects of genetic variants across multiple genes, we identify four gene modules associated with survival in estrogen receptor (ER)-negative and one in ER-positive disease. The modules show biological enrichment for cancer-related processes such as G-alpha signaling, circadian clock, angiogenesis, and Rho-GTPases in apoptosis.

  • Analysis of and prognostic information from disseminated tumour cells in bone marrow in primary breast cancer: a prospective observational study
  • 2012
  • Ingår i: BMC Cancer. - : Springer Science and Business Media LLC. - 1471-2407. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Disseminated tumour cells (DTCs) in the bone marrow of patients with breast cancer have been identified as an independent predictor of poor prognosis in patients with non-metastatic disease. This prospective study aimed to evaluate the presence and prognostic value of DTCs in the bone marrow of female patients with primary breast cancer. Methods: Between 1999 and 2003, bone marrow aspirates were obtained from patients at the time of surgery for primary invasive breast cancer. DTCs in bone marrow were identified using monoclonal antibodies against cytokeratins for detection of epithelial cells. The detection of DTCs was related to clinical follow-up with distant disease-free survival (DDFS) and breast cancer-specific survival as endpoints. Bone marrow aspirates from adult healthy bone marrow donors were analysed separately. Results: DTCs were analysed in 401 patients, and cytokeratin-positive cells were found in 152 of these (38%). An immunofluorescence (IF) staining procedure was used in 327 patients, and immunocytochemistry (IC) was performed in 74 patients. The IF-based method resulted in 40% DTC-positive cases, whereas 30% were positive using IC (p = 0.11). The presence of DTCs in bone marrow was not significantly related to patient or tumour characteristics. The presence of DTCs was not a prognostic factor for DDFS (IF: hazards ratio [HR], 2.2; 95% confidence interval [CI], 0.63-2.2; p = 0.60; IC: HR, 0.84; 95% CI, 0.09-8.1; p = 0.88). Significant prognostic factors were lymph node metastases, oestrogen receptor positivity, Nottingham histological grade, and tumour size using Cox univariate analysis. The analyses were positive for epithelial cells in bone marrow from adult healthy donors in 19 (25%) samples. Conclusions: The detection of DTCs in bone marrow in primary breast cancer was previously shown to be a predictor of poor prognosis. We were not able to confirm these results in a prospective cohort including unselected patients before the standard procedure was established. Future studies with a standardised patient protocol and improved technique for isolating and detecting DTCs may reveal the clinical applications of DTC detection in patients with micrometastases in the bone marrow.

  • Biomarkers in blood a few days after a bite by a Borrelia burgdorferi infected tick: : Asymptomatic Borrelia burgdorferi-infected subjects show higher Th1-associated response compared with subjects who later develop Lyme borreliosis
  • 2012
  • Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
    • The clinical outcome following infection with Borrelia (B.) burgdorferi sensu lato (s.l.) differs between individuals, ranging from asymptomatic infection to Lyme borreliosis (LB) with persistent symptoms post-treatment. Previous studies in mice and humans have generated the hypothesis that a successful outcome of B. burgdorferi s.l. infection is associated with an early strong pro-inflammatory T helper (Th)1-like immune response. The aim of this study was to assess the early course of events in B. burgdorferi s.l.-associated inflammation by screening for possible early immune biomarkers in peripheral blood from newly tick-bitten persons. The study subjects bitten by B. burgdorferi s.l.-infected ticks were divided into (1) those later developing clinical LB, (2) those who developed anti-B. burgdorferi s.l. antibodies but not clinical LB, (3) those who neither developed antibodies nor clinical LB. A fourth group consisted of bitten study subjects without development of antibodies or clinical LB. Two sets of samples, both comprising all four groups, were collected in order to repeat the analyses and confirm the data. Sera or plasma collected a few days after the tick bite were analysed for 18 biomarkers (IL-1β, IL-6, CXCL8/IL-8, IL-12p70, IL-17A, IL-27, TNF, CCL18, CCL20, CCL22, CXCL1, CXCL9, CXCL10, CXCL11, calprotectin, MMP-3, MMP-8, MMP-9) by multiplex bead assay and ELISA. In the first set of samples, the neutrophil activation marker calprotectin was increased in subjects who developed clinical LB compared with subjects who developed antibodies against B. burgdorferi s.l. but did not develop LB. However, the finding could not be confirmed in the second set of samples, thus the study failed to identify an early prognostic marker for development of clinical LB. Interestingly, both sets of samples showed increases in two different Th1-associated markers, CXCL10 and IL-12p70, respectively, in subjects who following a bite by a B. burgdorferi s.l.-infected tick developed antibodies against B. burgdorferi s.l. but did not develop LB compared with subjects who developed clinical LB, thus supporting the hypothesis of an early strong Th1-response being important for optimal resolution of B. burgdorferi s.l. infection.

    • Platelet-derived growth factors (PDGFs) and their receptors (PDGFRs) contribute to normal heart development. Deficient or abnormal expression of Pdgf and Pdgfr genes have a negative impact on cardiac development and function. The cellular effects of PDGFs in the hearts of Pdgf/Pdgfr mutants and the pathogenesis of the resulting abnormalities are poorly understood, but different PDGF isoforms induce varying effects. Here, we generated three new transgenic mouse types which complete a set of studies, where all different PDGF ligands have been expressed under the same heart specific alpha-myosin heavy chain promoter. Transgenic expression of the natural isoforms of Pdgfa and Pdgfb resulted in isoform specific fibrotic reactions and cardiac hypertrophy. Pdgfa overexpression resulted in a severe fibrotic reaction with up to 8-fold increase in cardiac size, leading to lethal cardiac failure within a few weeks after birth. In contrast, Pdgfb overexpression led to focal fibrosis and moderate cardiac hypertrophy. As PDGF-A and PDGF-B have different affinity for the two PDGF receptors, we analyzed the expression of the receptors and the histology of the fibrotic hearts. Our data suggest that the stronger fibrotic effect generated by Pdgfa overexpression was mediated by Pdgfrα in cardiac interstitial mesenchymal cells, i.e. the likely source of extracellular matrix depostion and fibrotic reaction. The apparent sensitivity of the heart to ectopic PDGFRα agonists supports a role for endogenous PDGFRα agonists in the pathogenesis of cardiac fibrosis. © 2016 The Authors

  • Dll4 signalling through Notch1 regulates formation of tip cells during angiogenesis.
  • 2007
  • Ingår i: Nature. - : Springer Science and Business Media LLC. - 1476-4687 .- 0028-0836. ; 445:7129, s. 776-80
  • Tidskriftsartikel (refereegranskat)abstract
    • In sprouting angiogenesis, specialized endothelial tip cells lead the outgrowth of blood-vessel sprouts towards gradients of vascular endothelial growth factor (VEGF)-A. VEGF-A is also essential for the induction of endothelial tip cells, but it is not known how single tip cells are selected to lead each vessel sprout, and how tip-cell numbers are determined. Here we present evidence that delta-like 4 (Dll4)-Notch1 signalling regulates the formation of appropriate numbers of tip cells to control vessel sprouting and branching in the mouse retina. We show that inhibition of Notch signalling using gamma-secretase inhibitors, genetic inactivation of one allele of the endothelial Notch ligand Dll4, or endothelial-specific genetic deletion of Notch1, all promote increased numbers of tip cells. Conversely, activation of Notch by a soluble jagged1 peptide leads to fewer tip cells and vessel branches. Dll4 and reporters of Notch signalling are distributed in a mosaic pattern among endothelial cells of actively sprouting retinal vessels. At this location, Notch1-deleted endothelial cells preferentially assume tip-cell characteristics. Together, our results suggest that Dll4-Notch1 signalling between the endothelial cells within the angiogenic sprout serves to restrict tip-cell formation in response to VEGF, thereby establishing the adequate ratio between tip and stalk cells required for correct sprouting and branching patterns. This model offers an explanation for the dose-dependency and haploinsufficiency of the Dll4 gene, and indicates that modulators of Dll4 or Notch signalling, such as gamma-secretase inhibitors developed for Alzheimer's disease, might find usage as pharmacological regulators of angiogenesis.

  • No clinical utility of KRAS variant rs61764370 for ovarian or breast cancer
  • 2016
  • Ingår i: Gynecologic Oncology. - : Elsevier BV. - 0090-8258 .- 1095-6859. ; 141:2, s. 386-401
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective Clinical genetic testing is commercially available for rs61764370, an inherited variant residing in a KRAS 3′ UTR microRNA binding site, based on suggested associations with increased ovarian and breast cancer risk as well as with survival time. However, prior studies, emphasizing particular subgroups, were relatively small. Therefore, we comprehensively evaluated ovarian and breast cancer risks as well as clinical outcome associated with rs61764370. Methods Centralized genotyping and analysis were performed for 140,012 women enrolled in the Ovarian Cancer Association Consortium (15,357 ovarian cancer patients; 30,816 controls), the Breast Cancer Association Consortium (33,530 breast cancer patients; 37,640 controls), and the Consortium of Modifiers of BRCA1 and BRCA2 (14,765 BRCA1 and 7904 BRCA2 mutation carriers). Results We found no association with risk of ovarian cancer (OR = 0.99, 95% CI 0.94-1.04, p = 0.74) or breast cancer (OR = 0.98, 95% CI 0.94-1.01, p = 0.19) and results were consistent among mutation carriers (BRCA1, ovarian cancer HR = 1.09, 95% CI 0.97-1.23, p = 0.14, breast cancer HR = 1.04, 95% CI 0.97-1.12, p = 0.27; BRCA2, ovarian cancer HR = 0.89, 95% CI 0.71-1.13, p = 0.34, breast cancer HR = 1.06, 95% CI 0.94-1.19, p = 0.35). Null results were also obtained for associations with overall survival following ovarian cancer (HR = 0.94, 95% CI 0.83-1.07, p = 0.38), breast cancer (HR = 0.96, 95% CI 0.87-1.06, p = 0.38), and all other previously-reported associations. Conclusions rs61764370 is not associated with risk of ovarian or breast cancer nor with clinical outcome for patients with these cancers. Therefore, genotyping this variant has no clinical utility related to the prediction or management of these cancers.

  • Towards 10-nm Soft X-Ray Zone Plate Fabrication
  • 2011
  • Konferensbidrag (refereegranskat)abstract
    • In this paper the latest efforts to improve our nanofabrication process for soft x‐ray zone plates is presented. The resolving power, which is proportional to the smallest outermost zone width of the zone plate, is increased by introducing cold development of the electron beam resist that is used for the patterning. With this process we have fabricated Ni zone plates with 13‐nm outermost zone and shown potential for making 11‐nm half‐pitch lines in the electron beam resist. Maintaining the diffraction efficiency of the zone plate is a great concern when the outermost zone width is decreased. To resolve this problem we have developed the so‐called Ni‐Ge zone plate in which the zone plate is build up by Ni and Ge, resulting in an increase of the diffraction efficiency. In a proof‐of‐principle experiment with 25‐nm Ni‐Ge zone plates, we have shown a doubling of the diffraction efficiency. When combined with cold development, the Ni‐Ge process has been shown to work down to 16‐nm half‐pitch. It is plausible that further refinement of the process will make it possible to go to 10‐nm outermost zone widths.

  • Ingår i: Journal of Analytical Toxicology. - : Oxford University Press (OUP). - 0146-4760 .- 1945-2403. ; 28:2, s. 94-104
  • Tidskriftsartikel (refereegranskat)abstract
    • Citalopram, a selective serotonin reuptake inhibitor, is one of the most commonly found drugs in Swedish forensic autopsy cases. Citalopram is a racemic drug with 50:50 of the S- and R- enantiomers. Enantioselective analysis of citalopram and its metabolites desmethylcitalopram and didesmethylcitalopram were performed in femoral blood from 53 autopsy cases by a chiral high-performance liquid chromatography (HPLC) method. The mean (± standard deviation) S/R ratio for citalopram was 0.67 ± 0.25 and for desmethylcitalopram, 0.68 ± 0.20. We found increasing S/R ratios with increasing concentrations of citalopram. We also found that high citalopram S/R ratios were associated with a high parent drug-to-metabolite ratio and may be an indicator of recent intake. Citalopram is metabolized by cytochrome P450 (CYP) 3A4, 2C19, and 2D6. Genotyping for the polymorphic CYP2C19 and CYP2D6 revealed no poor metabolizers regarding CYP2C19 and only 2 (3.8%) poor metabolizers regarding CYP2D6. The presence of drugs metabolized by and/or inhibiting these enzymes in several of the cases suggests that such pharmacokinetic interactions are a more important (practical) problem than metabolic deficiency. Enantioselective analysis of citalopram and its metabolites can provide additional information when interpreting forensic toxicology results and might be a necessity in the future.

  • 2017

  • Tidskriftsartikel (refereegranskat)abstract
    • Most non-BRCA1/2 breast cancer families have no identified genetic cause. We used linkage and haplotype analyses in familial and sporadic breast cancer cases to identify a susceptibility locus on chromosome 6q. Two independent genome-wide linkage analysis studies suggested a 3 Mb locus on chromosome 6q and two unrelated Swedish families with a LOD > 2 together seemed to share a haplotype in 6q14.1. We hypothesized that this region harbored a rare high-risk founder allele contributing to breast cancer in these two families. Sequencing of DNA and RNA from the two families did not detect any pathogenic mutations. Finally, 29 SNPs in the region were analyzed in 44,214 cases and 43,532 controls from BCAC, and the original haplotypes in the two families were suggested as low-risk alleles for European and Swedish women specifically. There was also some support for one additional independent moderate-risk allele in Swedish familial samples. The results were consistent with our previous findings in familial breast cancer and supported a breast cancer susceptibility locus at 6q14.1 around the PHIP gene.
