CARDIOMYOCYTE OGA HAPLOINSUFFICIENCY INCREASES O-GLCNACYLATION BUT HASTENS VENTRICULAR DYSFUNCTION FOLLOWING MYOCARDIAL INFARCTION.

Cardiomyocyte Oga haploinsufficiency increases O-GlcNAcylation but hastens ventricular dysfunction following myocardial infarction.

RationaleThe beta-O-linkage of N-acetylglucosamine (i.e., O-GlcNAc) to proteins is a pro-adaptive response to cellular insults.To this end, increased protein O-GlcNAcylation improves short-term survival of cardiomyocytes subjected to acute injury.This observation has been repeated by multiple groups and in multiple models; however, whether increase

High Glucose Induces Mouse Mesangial Cell Overproliferation via Inhibition of Hydrogen Sulfide Synthesis in a TLR-4-Dependent Manner

Background/Aims: Overproliferation of mesangial cells was believed to play an important role in the progress of diabetic nephropathy, one of the primary complications of diabetes.Hydrogen sulfide (H2S), a well-known and pungent gas with the distinctive smell of rotten eggs, was discovered to play a protective role in diabetic nephropathy.Methods: M
