Dynamic changes in pancreatic endocrine cell abundance, distribution, and function in antigen-induced and spontaneous autoimmune diabetes.

abstract：:The enzyme activities of mitochondrial glycerol phosphate dehydrogenase (mGPD) (EC 1.1.99.5) and pyruvate carboxylase (PC) (EC 6.4.1.1) have been reported to be low in the pancreatic islet of several rodent models of NIDDM. The present study was undertaken to discern whether mGPD is abnormal in the Zucker diabetic fat...
