Pancreatic beta cell senescence is one of the recent explanations for theincreased prevalence of type 2 diabetes in the elderly. Aging may exert a distinct influence on pancreatic β cell turnover, regeneration capacity and function. Oxidative stresses induced by metabolic stresses reduce pancreatic beta cell mass and secretion. We investigated how metabolic stresses effect on pancreatic beta cell senescence. INS-1 cells were exposed to 33mM glucose (glucotoxicity: high gl...

Beta cell senescence is being regarded as the one of the mechanisms of beta cell dysfunction. Melatonin secreted primarily from the pineal glandregulates a variety of physiological functions, such as sleep, circadian rhythms, and neuroendocrine actions. Melatonin has also very strong anti-oxidant effects. The effects of melatonin on the pancreatic beta cell senescence induced by glucolipotoxicity have not been studied. INS-1 cells were exposed to 33mM glucose with palmitate 20...

Introduction: Gestational diabetes mellitus (GDM) of increasing prevalence, lacks factors known to predict the prognosis of GDM. The correlations between levels of Oral Glucose Tolerance Test (OGTT) and BMI before pregnancy and the clinical progress of GDM were evaluated.Methods: Data of pregnant women diagnosed as GDM in Busanpaik hospital from January 1, 2010 to February 28, 2015 were studied. Correlations between patients’ OGTT in gestational age...
