Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- I 25 år har Centrum för kommunstrategisk forskning, CKS, varit ett nav för forskning och samverkan kring kommunal och regional utveckling. Den här boken är en del i uppmärksammandet av 25-årsjubiléet.Boken är en antologi som belyser frågor om hållbar utveckling utifrån kommunernas olika roller och ansvar för samhällsstrukturer och samhällsprocesser. Författarna till de olika kapitlen är forskare vid CKS och forskare som ingår i CKS samarbetsnätverk. I de olika kapitlen sammanfattas i flera fall forskning som har sträckt sig över många år. På så sätt visar vi genom den här boken hur kontinuiteten genom vår centrumbildning har bidragit till en livskraftig struktur för fördjupad kommunstrategisk och regionstrategisk forskning som tagit stöd i dialoger med miljöer utanför och innanför forskarsamhället.Redaktör för boken är Brita Hermelin, professor i kulturgeografi vid CKS. Övriga författare är Magnus Dahlstedt, David Ekholm, Gissur Ó Erlingsson, Ida Grundel, Sara Gustafsson, Robert Jonsson, Martin Klinthäll, Dick Magnusson, Kristina Trygg, Susanne Wallman Lundåsen, Emanuel Wittberg, Johan Wänström och Richard Öhrvall.

- OBJECTIVES: This study investigates the frequency and characteristics of carbapenemase-producing Escherichia coli/Klebsiella pneumoniae (CPE/K) and extended-spectrum cephalosporinase-producing E. coli/K. pneumoniae (ESCE/K) in healthy humans and livestock in rural Cambodia. Additionally, household practices as risk factors for faecal carriage of ESCE/K are identified.METHODS: Faecal samples were obtained from 307 humans and 285 livestock including large ruminants, pigs and poultry living in 100 households in rural Cambodia in 2011. Each household was interviewed, and multilevel logistic model determined associations between household practices/meat consumption and faecal carriage of ESCE/K. CPE and ESCE/K were detected and further screened for colistin resistance genes.RESULTS: CPE/K isolates harbouring blaOXA-48 were identified in two humans. The community carriage of ESCE/K was 20% in humans and 23% in livestock. The same ESBL genes: blaCTX-M-15 , blaCTX-M-14 , blaCTX-M-27 , blaCTX-M-55 , blaSHV-2 , blaSHV-12 , blaSHV-28 ; AmpC genes: blaCMY-2 , blaCMY-42, blaDHA-1 ; and colistin resistance genes: mcr-1-like and mcr-3-like were detected in humans and livestock. ESCE/K was frequently detected in women, young children, pigs and poultry, which are groups in close contact. The practice of burning or burying meat waste and not collecting animal manure indoors and outdoors daily were identified as risk factors for faecal carriage of ESCE/K.CONCLUSIONS: Faecal carriage of E. coli and K. pneumoniae harbouring extended-spectrum cephalosporinase genes are common in the Cambodian community, especially in women and young children. Exposure to animal manure and slaughter products are risk factors for intestinal colonization of ESCE/K in humans.

- OBJECTIVE: To estimate the prospective association between the exposure to three types of gender-based violence and harassment (GBVH) and psychotropic medication.METHODS: Information on three measures of workplace GBVH-sexual harassment (1) from superiors or colleagues, (2) from others (eg, clients) and (3) gender harassment from superiors or colleagues-were retrieved from the biannual Swedish Work Environment Survey 2007-2013 (N=23 449), a representative sample of working 16-64 years old registered in Sweden. The survey answers were merged with data on antidepressants, hypnotics/sedatives and anxiolytics from the Swedish Prescribed Drug Register. Cox proportional hazards analyses with days to purchase as time scale and first instance of medicine purchase as failure event were fitted, adjusted for demographic and workplace factors.RESULTS: Workers who reported exposure to gender harassment only (HR 1.2, 95% CI 1.07 to 1.36), to sexual but not gender harassment (HR 1.21, 95% CI 1.04 to 1.40), or to gender and sexual harassment (HR 1.31, 95% CI 1.08 to 1.60) had an excess risk of psychotropics use in comparison to workers who reported neither of the exposures in the past 12 months. We found no interaction between the exposures and gender in the association with psychotropics use.CONCLUSIONS: Exposure to sexual or gender harassment at the workplace may contribute to the development of mental disorders.

Tidskriftsartikel (refereegranskat)abstract
- Aim:Compared to middle-aged women, young women with breast cancer have a higher risk of systemic disease. We studied expression of proliferation markers in relation to age and subtype and their association with long-term prognosis.Methods:Distant disease-free survival (DDFS) was studied in 504 women aged <40 years and 383 women aged >= 40 years from a population-based cohort. Information on patient characteristics, treatment and follow-up was collected from medical records. Tissue microarrays were produced for analysis of oestrogen receptor, progesterone receptor (PR), Her2, Ki-67 and cyclins.Results: Young women with luminal tumours had significantly higher expression of Ki-67 and cyclins. Proliferation markers were prognostic only within this subtype. Ki-67 was a prognostic indicator only in young women with luminal PR+ tumours. The optimal cut-off for Ki-67 varied by age. High expression of cyclin E1 conferred a better DDFS in women aged <40 years with luminal PR- tumours (hazard ratio [HR] 0.47 [0.24-0.92]). Age < 40 years was an independent risk factor of DDFS exclusively in women with luminal B PR+ tumours (HR 2.35 [1.22-4.50]). Young women with luminal B PR- tumours expressing low cyclin E1 had a six-fold risk of distant disease compared with luminal A ( HR 6.21 [2.17-17.6]).Conclusions:The higher expression of proliferation markers in young women does not have a strong impact on prognosis. Ki-67 is only prognostic in the subgroup of young women with luminal PR tumours. The only cyclin adding prognostic value beyond subtype is cyclin E1. Age is an independent prognostic factor only in women with luminal B PR+ tumours.

Tidskriftsartikel (refereegranskat)abstract
- Background: Anillin (ANLN), an actin-binding protein required for cytokinesis, has recently been presented as part of a prognostic marker panel in breast cancer. The objective of the current study was to further explore the prognostic and functional value of ANLN as a single biomarker in breast cancer. Methods: Immunohistochemical assessment of ANLN protein expression was performed in two well characterized breast cancer cohorts (n = 484) with long-term clinical follow-up data and the results were further validated at the mRNA level in a publicly available transcriptomics dataset. The functional relevance of ANLN was investigated in two breast cancer cell lines using RNA interference. Results: High nuclear fraction of ANLN in breast tumor cells was significantly associated with large tumor size, high histological grade, high proliferation rate, hormone receptor negative tumors and poor prognosis in both examined cohorts. Multivariable analysis showed that the association between ANLN and survival was significantly independent of age in cohort I and significantly independent of proliferation, as assessed by Ki-67 expression in tumor cells, age, tumor size, ER and PR status, HER2 status and nodal status in cohort II. Analysis of ANLN mRNA expression confirmed that high expression of ANLN was significantly correlated to poor overall survival in breast cancer patients. Consistent with the role of ANLN during cytokinesis, transient knock-down of ANLN protein expression in breast cancer cell lines resulted in an increase of senescent cells and an accumulation of cells in the G2/M phase of the cell cycle with altered cell morphology including large, poly-nucleated cells. Moreover, ANLN siRNA knockdown also resulted in decreased expression of cyclins D1, A2 and B1. Conclusions: ANLN expression in breast cancer cells plays an important role during cell division and a high fraction of nuclear ANLN expression in tumor cells is correlated to poor prognosis in breast cancer patients, independent of Ki-67, tumor size, hormone receptor status, HER2 status, nodal status and age.

Protein Expression Profiling of Cancer Biomarkers
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The Human Protein Atlas project is a Swedish research initiative that uses antibody-based proteomics for large scale protein profiling in human tissues and cells. Affinity-purified antibodies are produced within the project and used for immunohistochemical staining on tissue micro arrays (TMAs) in order to map the human proteome and publish the result in a protein atlas (www.proteinatlas.org). In this thesis, TMAs were used for analysis of protein expression patterns in order to identify and explore potential biomarkers of clinical relevance.In Paper I, protein expression of SATB2 was studied in colorectal cancer. The results show that SATB2 is a sensitive and specific biomarker for colorectal cancer, staining 85% of all investigated tumors. Moreover, SATB2 in combination with CK20 showed positivity in 97% of all colorectal carcinomas and is therefore suitable as a complementary tool in clinical differential diagnostics of cancer.In Paper II, ANLN was explored as a prognostic biomarker for breast cancer. A high nuclear fraction of ANLN in breast cancer was significantly correlated to large tumor size, high histological grade, hormone receptor negative tumors, high proliferation rate and poor prognosis. Furthermore, ANLN depletion in breast cancer cell lines resulted in cell cycle arrest and cellular senescence with altered cell morphology.In Paper III, young age at breast cancer diagnosis was investigated as an independent risk factor for poor prognosis. TMAs were produced from a selection of patients from a previously defined register-based cohort. The analysis shows that young women with luminal B tumors have a 2.2-fold higher risk of dying of breast cancer compared to older women.In Paper IV, vascular expression of CD93 was explored by image analysis of the tissue-based breast cancer cohort produced in Paper III. The analysis shows that young women with breast cancer display a significantly higher CD93-positive vessel area in their tumors. High CD93-positive vessel area was significantly associated with hormone receptor negative tumors, grade, Ki-67, EGFR and a poor prognosis.In conclusion, this thesis shows that protein expression profiling using TMAs is an important tool for identifying and exploring potential novel biomarkers for cancer.

- The different chambers of the human heart demonstrate regional physiological traits and may be differentially affected during pathologic remodeling, resulting in heart failure. Few previous studies have, however, characterized the different chambers at a transcriptomic level. We therefore conducted whole-tissue RNA sequencing and gene set enrichment analysis of biopsies collected from the four chambers of adult failing (n = 8) and nonfailing (n = 11) human hearts. Atria and ventricles demonstrated distinct transcriptional patterns. Compared to nonfailing ventricles, the transcriptional pattern of nonfailing atria was enriched for a large number of gene sets associated with cardiogenesis, the immune system and bone morphogenetic protein (BMP), transforming growth factor beta (TGF beta), MAPK/JNK and Wnt signaling. Differences between failing and nonfailing hearts were also determined. The transcriptional pattern of failing atria was distinct compared to that of nonfailing atria and enriched for gene sets associated with the innate and adaptive immune system, TGF beta/SMAD signaling, and changes in endothelial, smooth muscle cell and cardiomyocyte physiology. Failing ventricles were also enriched for gene sets associated with the immune system. Based on the transcriptomic patterns, upstream regulators associated with heart failure were identified. These included many immune response factors predicted to be similarly activated for all chambers of failing hearts. In summary, the heart chambers demonstrate distinct transcriptional patterns that differ between failing and nonfailing hearts. Immune system signaling may be a hallmark of all four heart chambers in failing hearts, and could constitute a novel therapeutic target.
