    ..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
    ..NASH induced by an atherogenic diet is not influenced by loss of SNTA. The present study suggests the use of different experimental NASH models to study the pathophysiological role of proteins like SNTA in NASH. ..
