Insulin resistance and the metabolism of branched-chain amino acids

Jingyi Lu, Guoxiang Xie, Weiping Jia, Wei Jia

Frontiers of Medicine 2013, Volume 7, Issue 1,   Pages 53-59 doi: 10.1007/s11684-013-0255-5

Abstract: Branched-chain amino acids (BCAAs), namely valine, leucine and isoleucine, are among the nine essentialamino acids, accounting for 35% of the essential amino acids in muscle proteins and 40% of the preformedamino acids required by mammals.The BCAAs are particularly responsive to the inhibitory insulin action on amino acid release by skeletal

Bile acids and their effects on diabetes

Cynthia Rajani, Wei Jia

Frontiers of Medicine 2018, Volume 12, Issue 6,   Pages 608-623 doi: 10.1007/s11684-018-0644-x

Abstract: Diabetes is a widespread, rapidly increasing metabolic disease that is driven by hyperglycemia. Early glycemic control is of primary importance to avoid vascular complications including development of retinal disorders leading to blindness, end-stage renal disease, and accelerated atherosclerosis with a higher risk of myocardial infarction, stroke and limb amputations. Even after hyperglycemia has been brought under control, “metabolic memory,” a cluster of irreversible metabolic changes that allow diabetes to progress, may persist depending on the duration of hyperglycemia. Manipulation of bile acid (BA) receptors and the BA pool have been shown to be useful in establishing glycemic control in diabetes due to their ability to regulate energy metabolism by binding and activating nuclear transcription factors such as farnesoid X receptor (FXR) in liver and intestine as well as the G-protein coupled receptor, TGR5, in enteroendocrine cells and pancreatic -cells. The downstream targets of BA activated FXR, FGF15/21, are also important for glucose/insulin homeostasis. In this review we will discuss the effect of BAs on glucose and lipid metabolism and explore recent research on establishing glycemic control in diabetes through the manipulation of BAs and their receptors in the liver, intestine and pancreas, alteration of the enterohepatic circulation, bariatric surgery and alignment of circadian rhythms.
