Mechanism and research advances regarding adaption of nutrition insufficiency for tumor cells
-
摘要: 由于具有无限增殖的特点及有氧糖酵解的能量代谢方式，肿瘤细胞对于葡萄糖和谷氨酰胺等营养物质的需求远超过正常细胞，常处于营养缺乏状态。然而，肿瘤细胞可通过某些特定蛋白感知肿瘤微环境中营养物质的供给变化，调控相应的信号通路，阻滞细胞周期、代谢或调节细胞自噬等多种途径适应饥饿状态并不断演进。本综述旨在介绍低营养状态下肿瘤细胞的感知机制、下游效应因子的变化。

Abstract: Given the unlimited proliferation and aerobic glycolysis in tumor cells, these cells require more glucose, glutamine, and other nutrients compared with normal cells. Tumor cells are often affected by insufficient nutrient supply. However, by sensing changes in the nutrient supply in tumor microenvironment and by regulating signal-transduction pathways, some specific proteins can help tumor cells in blocking the cell cycle, reprogramming metabolism, and regulating autophagy to progress and survive against nutri-ent stress. Exciting innovations have been made to elucidate the mechanisms relevant to this process. This review aims to highlight re -cent studies on the mechanisms of sensing the low nutrient supply in microenvironments, as well as the downstream effect factors in cancer cells. -
