.Purposes,To explore the effects of carnosine on high glucose-induced apoptosis of human umbilical vein endothelial cells (HUVECs). Methods HUVECs were cultured in vitro. The cellular apoptotic model was made by the addition of high glucose (25 mmol/L), the group of high glucose and carnosine was administered by the addition of high glucose (25 mmol/L) with carnosine (20 mmol/L). In addition, cell apoptosis was detected by the electron microscopy and AnnexinV/PI flow cytometry. Results Compared with the control group, high glucose could induce HUVECs apoptosis under electron microscopy and AnnexinV/PI flow cytometry, while 20 mmol/L carnosine could inhibit the apoptosis induced by high glucose significantly (##P <0.05). Conclusion In this study, carnosine could inhibit high-glucose induced apoptosis of human umbilical vein endothelial cells.

AbstractWe recently identified a kidney risk inflammatory signature (KRIS), comprising 6 TNF receptors (including TNFR1 and TNFR2) and 11 inflammatory proteins. Elevated levels of these proteins in circulation were strongly associated with risk of the development of end-stage kidney disease (ESKD) during 10-year follow-up. It has been hypothesized that elevated levels of these proteins in circulation might reflect (be markers of) systemic exposure to TNFα. In this in vitro study, we examined intracellular and extracellular levels of these proteins in human umbilical vein endothelial cells (HUVECs) exposed to TNFα in the presence of hyperglycemia. KRIS proteins as well as 1300 other proteins were measured using the SOMAscan proteomics platform. Four KRIS proteins (including TNFR1) were down-regulated and only 1 protein (IL18R1) was up-regulated in the extracellular fraction of TNFα-stimulated HUVECs. In the intracellular fraction, one KRIS protein was down-regulated (CCL14) and 1 protein was up-regulated (IL18R1). The levels of other KRIS proteins were not affected by exposure to TNFα. HUVECs exposed to a hyperglycemic and inflammatory environment also showed significant up-regulation of a distinct set of 53 proteins (mainly in extracellular fraction). In our previous study, circulating levels of these proteins were not associated with progression to ESKD in diabetes.
