• when fed a high fat diet, mice show no differences in beta cell mass or in glucose tolerance and insulin secretion following intraperitoneal glucose injections relative to similarly treated control mice

endocrine/exocrine glands
• primary pancreatic islet cells exhibit reduced sensitivity to cytokines- or palmitic acid-induced apoptosis, as measured by a TUNEL assay
• islets show increased expression of the anti-apoptotic proteins Bcl2, Bcl2l1 (Bcl-xL), as well as increased expression and phosphorylation of Bad, which inhibits its pro-apoptotic activity
