    • Aggressive behavior displays a high heritability in our study group of Golden Retriever dogs. Alterations in brain serotonin metabolism have been described in aggressive dogs before. Here, we evaluate whether four genes of the canine serotonergic system, coding for the serotonin receptors 1A, 1B, and 2A, and the serotonin transporter, could play a major role in aggression in Golden Retrievers. We performed mutation screens, linkage analysis, an association study, and a quantitative genetic analysis. There was no systematic difference between the coding DNA sequence of the candidate genes in aggressive and non-aggressive Golden Retrievers. An affecteds-only parametric linkage analysis revealed no strong major locus effect on human-directed aggression related to the candidate genes. An analysis of 41 single nucleotide polymorphisms (SNPs) in the 1 Mb regions flanking the genes in 49 unrelated human-directed aggressive and 49 unrelated non-aggressive dogs did not show association of SNP alleles, genotypes, or haplotypes with aggression at the candidate loci. We completed our analyses with a study of the effect of variation in the candidate genes on a collection of aggression-related phenotypic measures. The effects of the candidate gene haplotypes were estimated using the Restricted Maximum Likelihood method, with the haplotypes included as fixed effects in a linear animal model. We observed no effect of the candidate gene haplotypes on a range of aggression-related phenotypes, thus extending our conclusions to several types of aggressive behavior. We conclude that it is unlikely that these genes play a major role in the variation in aggression in the Golden Retrievers that we studied. Smaller phenotypic effects of these loci could not be ruled out with our sample size.

  • The African coelacanth genome provides insights into tetrapod evolution
  • 2013
  • In: Nature. - : Springer Science and Business Media LLC. - 0028-0836 .- 1476-4687. ; 496:7445, s. 311-316
  • Journal article (peer-reviewed)abstract
    • The discovery of a living coelacanth specimen in 1938 was remarkable, as this lineage of lobe-finned fish was thought to have become extinct 70 million years ago. The modern coelacanth looks remarkably similar to many of its ancient relatives, and its evolutionary proximity to our own fish ancestors provides a glimpse of the fish that first walked on land. Here we report the genome sequence of the African coelacanth, Latimeria chalumnae. Through a phylogenomic analysis, we conclude that the lungfish, and not the coelacanth, is the closest living relative of tetrapods. Coelacanth protein-coding genes are significantly more slowly evolving than those of tetrapods, unlike other genomic features. Analyses of changes in genes and regulatory elements during the vertebrate adaptation to land highlight genes involved in immunity, nitrogen excretion and the development of fins, tail, ear, eye, brain and olfaction. Functional assays of enhancers involved in the fin-to-limb transition and in the emergence of extra-embryonic tissues show the importance of the coelacanth genome as a blueprint for understanding tetrapod evolution.

  • Tension-free mesh versus suture-alone cruroplasty in antireflux surgery : a randomized, double-blind clinical trial
  • 2020
  • In: British Journal of Surgery. - : John Wiley & Sons. - 0007-1323 .- 1365-2168. ; 107:13, s. 1731-1740
  • Journal article (peer-reviewed)abstract
    • BackgroundAntireflux surgery is effective for the treatment of gastro-oesophageal reflux disease (GORD) but recurrence of hiatal hernia remains a challenge. In other types of hernia repair, use of mesh is associated with reduced recurrence rates. The aim of this study was to compare the use of mesh versus sutures alone for the repair of hiatal hernia in laparoscopic antireflux surgery.MethodsPatients undergoing laparoscopic Nissen fundoplication for GORD between January 2006 and December 2010 were allocated randomly to closure of the diaphragmatic hiatus with crural sutures or non-absorbable polytetrafluoroethylene mesh (CruraSoft®). The primary outcome was recurrence of hiatal hernia, as determined by barium swallow study 12 months after surgery. Secondary outcomes were: intraoperative and postoperative complications, use of antireflux medication, postoperative oesophageal acid exposure, quality of life, dysphagia and duration of hospital stay.ResultsSome 77 patients were randomized to the suture technique and 82 patients underwent mesh repair. At 1 year, the hiatal hernia had recurred in six of 64 patients (9 per cent) in the mesh group and two of 64 (3 per cent) in the suture group (P = 0·144). Reflux symptoms, use of proton pump inhibitors and oesophageal acid exposure did not differ between the groups. At 3 years, recurrence rates were 13 and 10 per cent in the mesh and suture groups respectively (P = 0·692). Dysphagia scores decreased in both groups, but more patients had dysphagia for solid food after mesh closure (P = 0·013). Quality-of-life scores were comparable between the groups.ConclusionTension-free crural repair with non-absorbable mesh does not reduce the incidence of recurrent hiatal hernia compared with use of sutures alone in patients undergoing laparoscopic fundoplication. NCT03730233 (http://www.clinicaltrials.gov).

  • Triple specificity of ZnT8 autoantibodies in relation to HLA and other islet autoantibodies in childhood and adolescent type 1 diabetes

    • Andersson C, Vaziri-Sani F, Delli AJ, Lindblad B, Carlsson A, Forsander G, Ludvigsson J, Marcus C, Samuelsson U, Ivarsson SA, Lernmark A, Elding Larsson H, the BDD Study group. Triple specificity of ZnT8 autoantibodies in relation to HLA and other islet autoantibodies in childhood and adolescent type 1 diabetes. Pediatric Diabetes 2013: 14: 97-105. Objective To establish the diagnostic sensitivity of and the relationships between autoantibodies to all three Zinc transporter 8 (Zinc transporter 8 autoantibody to either one, two, or all three amino acid variants at position 325, ZnT8A) variants to human leukocyte antigen (HLA)-DQ and to autoantibodies to glutamic acid decarboxylase (GADA), insulinoma-associated protein 2 (IA-2A), and insulin (IAA). Methods We analyzed 3165 patients with type 1 diabetes (T1D) in the Better Diabetes Diagnosis study for HLA-DQ genotypes and all six autoantibodies (ZnT8RA, arginine 325 Zinc transporter 8 autoantibody; ZnT8WA, tryptophan 325 Zinc transporter 8 autoantibody; ZnT8QA, glutamine 325 Zinc transporter 8 autoantibody; GADA, IA-2A, and IAA). Results ZnT8A was found in 65% of the patients and as many as 108 of 3165 (3.4%) had 13 ZnT8A alone. None had ZnT8QA alone. Together with GADA (56%), IA-2A (73%), and IAA (33%), 93% of the T1D patients were autoantibody positive. All three ZnT8A were less frequent in children below 2 yr of age (pandlt;0.0001). All three ZnT8A were associated with DQA1-B1*X-0604 (DQ6.4) and DQA1-B1*03-0302 (DQ8). ZnT8WA and ZnT8QA were negatively associated with DQA1-B1*05-02 (DQ2). Conclusions Analysis of ZnT8A increased the diagnostic sensitivity of islet autoantibodies for T1D as only 7% remained islet autoantibody negative. The association between DQ6.4 and all three ZnT8A may be related to ZnT8 antigen presentation by the DQ6.4 heterodimer.
