    ..More research is needed to fully understand the pathways that control chemerin processing and chemerin signaling. ..
  2. Krautbauer S, Neumeier M, Haberl E, Pohl R, Feder S, Eisinger K, et al. The utrophin-beta 2 syntrophin complex regulates adipocyte lipid droplet size independent of adipogenesis. Mol Cell Biochem. 2019;452:29-39 pubmed publisher
    ..Collectively, our data provide evidence that the utrophin-SNTB2 complex regulates LD size without affecting adipogenesis. ..
  3. Rein Fischboeck L, Bajraktari G, Pohl R, Feder S, Eisinger K, Mages W, et al. Alpha-syntrophin dependent expression of tubulin alpha 8 protein in hepatocytes. J Physiol Biochem. 2018;74:511-521 pubmed publisher
    ..Yet, knock down of SNTA did neither affect proliferation nor viability of Hepa1-6 cells. The present study shows that SNTA protein levels are inversely related to TUBA8 protein expression in the hepatocyte cell line Hepa1-6. ..
  4. Haberl E, Pohl R, Rein Fischboeck L, Feder S, Eisinger K, Krautbauer S, et al. Ex vivo analysis of serum chemerin activity in murine models of obesity. Cytokine. 2018;104:42-45 pubmed publisher
    ..While increased total serum chemerin is a consistent finding among rodent obesity models, this may not accurately reflect changes in chemerin bioactivity which is the major determinant of biological effects. ..
  5. Pohl R, Rein Fischboeck L, Meier E, Eisinger K, Krautbauer S, Buechler C. Resolvin E1 and chemerin C15 peptide do not improve rodent non-alcoholic steatohepatitis. Exp Mol Pathol. 2015;98:295-9 pubmed publisher
    ..This excludes low receptor levels as reason for therapeutic failure. In summary, current data demonstrate that RvE1 and chemerin derived C15 peptide do not ameliorate murine NASH. ..

    ..The antigen detected by the fourth antibody has not been identified but is different from SNTA and SNTB2. Therefore, only one of the four tested antibodies is appropriate to analyze SNTA protein levels by immunoblot. ..
  7. Rein Fischboeck L, Krautbauer S, Eisinger K, Pohl R, Meier E, Weiss T, et al. Hepatic scavenger receptor BI is associated with type 2 diabetes but unrelated to human and murine non-alcoholic fatty liver disease. Biochem Biophys Res Commun. 2015;467:377-82 pubmed publisher
    ..SR-BI was higher in type 2 diabetes patients but not in those with hypercholesterolemia. The current study indicates a minor if any role of SR-BI in human and murine NAFLD. ..

Biochim Biophys Acta Mol Cell Biol Lipids. 2018;1863:526-537 pubmed publisher
