Shortening of telomere length by metabolic factors in diabetes: protective effects of fenofibrate.

ABSTRACT: People with diabetes mellitus have shorter telomeres compared with non-diabetic subjects. The aim of this study was to investigate an in-vitro model of telomere shortening under diabetes metabolic conditions. The mechanisms of the accelerated telomere length attrition and the potential telomere protective action of fenofibrate with related cellular mechanisms were also examined. Human dermal fibroblasts were passaged and cultured in normal (5.5 mM) or high (25 mM) D-glucose, across 7 days with hydrogen peroxide (H₂O₂), glucosamine (GA), or glycated albumin (AGEs-BSA). Relative telomere length (RTL) was determined by qPCR. The expression of shelterin complex members which regulate telomere stability were measured by qRT-PCR and Western immunoblot. Culture in high gluco
