Type 2 diabetes mellitus is characterized by insulin resistance and failure of pancreatic β-cells producing insulin. Autophagy plays a crucial role in cellular homeostasis through degradation and recycling of organelles such as mitochondria or endoplasmic reticulum (ER). Here we discussed the role of β-cell autophagy in development of diabetes, based on our(More)
Autophagy plays a crucial role in the maintenance of cellular nutrient balance and the function of organelles such as mitochondria or the endoplasmic reticulum, which are important in intracellular metabolism, insulin release, and insulin sensitivity. In the insulin-producing pancreatic β-cells, autophagy is important in the maintenance of β-cell mass,(More)
Autophagy is a catabolic cellular process involving the degradation of the cell's own components. Although the role of autophagy of diverse tissues in body metabolism has been investigated, the importance of autophagy in hypothalamic proopiomelanocortin (POMC) neurons, key regulators of energy balance, has not been addressed. The role of autophagy in leptin(More)
Dopaminergic drugs increase the expression of the proto-oncogene, c-fos, in the brain, which is involved in the coordination of neurobiological changes caused by repeated cocaine or amphetamine use. This study examined the roles of five dopamine receptor subtypes on the c-fos promoter activity. D(1)R or D(5)R significantly increased the expression of c-fos(More)
