亮氨酸是一种在日常饮食中必须提供的支链氨基酸,在控制蛋白质合成和调节各种细胞类型的细胞代谢中起重要作用。在胰腺β细胞中,亮氨酸通过充当代谢燃料和谷氨酸脱氢酶的变构激活剂来增强β-氨基丁酸的分解,从而急性刺激胰岛素分泌。亮氨酸还显示在生理浓度下通过mTOR依赖性和非依赖性途径调节胰岛β细胞中的基因转录和蛋白质合成。亮氨酸的长期治疗已显示通过上调某些关键代谢基因来改善人糖尿病胰岛的胰岛素分泌功能障碍。在体内,亮氨酸给药改善了患有2型糖尿病的人类和啮齿动物的血糖控制。本文就亮氨酸代谢对胰岛β细胞功能影响的研究进展进行综述。
Leucine, a the branched-chain amino acids that must be supplied in daily diet, plays an important role in controlling protein synthesis and regulating cell metabolism in various cell types. In pancreatic β cells, leucine acutely stimulates insulin secretion by serving as both metabolic fuel and allosteric activator of glutamate dehydrogenase to enhance glutaminolysis. Leucine has also been shown to regulate gene transcription and protein synthesis in pancreatic islet β cells via both mTOR-dependent and -independent pathways at physiological concentrations. Long-term treatment of leucine has been shown to improve insulin secretory dysfunction of human diabetic islets via upregulation of certain key metabolic genes. In vivo, leucine administration improves glycemic control in humans and rodents with type 2 diabetes. This review aims to summarize and discuss the recent findings regarding the effects of leucine metabolism on pancreatic β cell function.
