Genome-wide linkage analyses localized more than 290 quantitative trait loci (QTL) for obesity, 190 QTL for diabetes-related traits and 100 QTL for plasma metabolites in the out-cross populations. A computational framework was developed that allowed to refine critical regions and to nominate a small number of candidate genes by integrating reciprocal haplotype mapping and transcriptome data. The efficiency of the complex procedure was demonstrated for one obesity QTL. The genomic interval of 35 Mb with 502 annotated candidate genes was narrowed down to six candidates. Accordingly, congenic mice retained the obesity phenotype owing to an interval that contains three of the six candidate genes. Among these the phospholipase PLA2G4A exhibited an elevated expression in adipose tissue of obese human subjects and is therefore a critical regulator of the obesity locus. Together, our broad and complex approach demonstrates that combined- and comparative-cross analysis exhibits improved mapping resolution and represents a valid tool for the identification of disease genes.}, language = {en} } @misc{Vogel2007, type = {Master Thesis}, author = {Vogel, Nicole}, title = {„...das ist mein gr{\"o}ßter Druck" : eine empirische Untersuchung zum Umgang mit Handlungsdilemmata von Sozialarbeiter/innen in der Jugendberufshilfe}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-16478}, school = {Universit{\"a}t Potsdam}, year = {2007}, abstract = {Die sozialen Sicherungs- und F{\"u}rsorgesysteme in Deutschland befinden sich in einem radikalen Umbau im Sinne eines neoliberalen Gesellschaftsmodells mit der Folge, dass sich die gesellschaftlichen Widerspr{\"u}che und Konflikte zuspitzen. Gleichzeitig weisen die aktuellen Debatten in der Sozialen Arbeit darauf hin, dass die gesellschaftlichen, und damit strukturellen, Widerspr{\"u}che in deren Mitte angekommen sind. Sie manifestieren sich u.a. in Handlungsdilemmata, mit denen die Sozialarbeiter/innen in ihrem Berufsalltag und in ihrer p{\"a}dagogischen Praxis konfrontiert sind und auf die sie reagieren (m{\"u}ssen). Hier liegt auch der Ausgangspunkt der vorliegenden Arbeit. Es wird der Frage nachgegangen, welche Strategien die in der Jugendberufshilfe t{\"a}tigen Sozialarbeiter/innen bei der Konfrontation mit sich widersprechenden Handlungsanforderungen entwickeln, die sich aus den institutionellen und gesellschaftlichen Rahmenbedingungen einerseits und der sozialp{\"a}dagogischen Berufspraxis andererseits ergeben. Von besonderem Interesse ist die Frage, welche Probleme und Handlungsdilemmata {\"u}berhaupt von den Sozialarbeiter/innen wahrgenommen werden. Der Fokus dieser Arbeit liegt auf der Jugendsozialarbeit, und insbesondere auf der Jugendberufshilfe, als demjenigen Teil des sozialen Sicherungssystems, der sich speziell an individuell beeintr{\"a}chtigte und sozial benachteiligte Jugendliche richtet und an ihrer {\"U}bergangsproblematik ansetzt. Dem qualitativen Forschungsansatz der grounded theory folgend werden zwei Fallanalysen von Sozialarbeiterinnen durchgef{\"u}hrt, die als Beraterinnen am {\"U}bergang Schule - Beruf t{\"a}tig sind. Die Ergebnisse weisen darauf hin, dass die Umgangsformen mit Handlungsdilemmata in einem engen individuellen, institutionellen sowie gesellschaftlichen Kontext stehen, da sie stets gleichsam eine individuelle, institutionelle und gesellschaftliche Funktion erf{\"u}llen.}, language = {de} } @article{AgaBarfknechtHallahanGottmannetal.2020, author = {Aga-Barfknecht, Heja and Hallahan, Nicole and Gottmann, Pascal and J{\"a}hnert, Markus and Osburg, Sophie and Schulze, Gunnar and Kamitz, Anne and Arends, Danny and Brockmann, Gudrun and Schallschmidt, Tanja and Lebek, Sandra and Chadt, Alexandra and Al-Hasani, Hadi and Joost, Hans-Georg and Sch{\"u}rmann, Annette and Vogel, Heike}, title = {Identification of novel potential type 2 diabetes genes mediating beta-cell loss and hyperglycemia using positional cloning}, series = {Frontiers in genetics}, volume = {11}, journal = {Frontiers in genetics}, publisher = {Frontiers Media}, address = {Lausanne}, issn = {1664-8021}, doi = {10.3389/fgene.2020.567191}, pages = {11}, year = {2020}, abstract = {Type 2 diabetes (T2D) is a complex metabolic disease regulated by an interaction of genetic predisposition and environmental factors. To understand the genetic contribution in the development of diabetes, mice varying in their disease susceptibility were crossed with the obese and diabetes-prone New Zealand obese (NZO) mouse. Subsequent whole-genome sequence scans revealed one major quantitative trait loci (QTL),Nidd/DBAon chromosome 4, linked to elevated blood glucose and reduced plasma insulin and low levels of pancreatic insulin. Phenotypical characterization of congenic mice carrying 13.6 Mbp of the critical fragment of DBA mice displayed severe hyperglycemia and impaired glucose clearance at week 10, decreased glucose response in week 13, and loss of beta-cells and pancreatic insulin in week 16. To identify the responsible gene variant(s), further congenic mice were generated and phenotyped, which resulted in a fragment of 3.3 Mbp that was sufficient to induce hyperglycemia. By combining transcriptome analysis and haplotype mapping, the number of putative responsible variant(s) was narrowed from initial 284 to 18 genes, including gene models and non-coding RNAs. Consideration of haplotype blocks reduced the number of candidate genes to four (Kti12,Osbpl9,Ttc39a, andCalr4) as potential T2D candidates as they display a differential expression in pancreatic islets and/or sequence variation. In conclusion, the integration of comparative analysis of multiple inbred populations such as haplotype mapping, transcriptomics, and sequence data substantially improved the mapping resolution of the diabetes QTLNidd/DBA. Future studies are necessary to understand the exact role of the different candidates in beta-cell function and their contribution in maintaining glycemic control.}, language = {en} } @book{RanaMohapatraSidorovaetal.2022, author = {Rana, Kaushik and Mohapatra, Durga Prasad and Sidorova, Julia and Lundberg, Lars and Sk{\"o}ld, Lars and Lopes Grim, Lu{\´i}s Fernando and Sampaio Gradvohl, Andr{\´e} Leon and Cremerius, Jonas and Siegert, Simon and Weltzien, Anton von and Baldi, Annika and Klessascheck, Finn and Kalancha, Svitlana and Lichtenstein, Tom and Shaabani, Nuhad and Meinel, Christoph and Friedrich, Tobias and Lenzner, Pascal and Schumann, David and Wiese, Ingmar and Sarna, Nicole and Wiese, Lena and Tashkandi, Araek Sami and van der Walt, Est{\´e}e and Eloff, Jan H.
