细胞的氧化还原环境受到活性氧(ROS)的产生和清除的影响。近年来,一些报告支持细胞ROS水平可以作为“第二信使”调节许多细胞过程(包括增殖)的假设。细胞氧化还原环境中的周期性振荡(氧化还原循环)调节细胞周期从静止(G0)到增殖(G1、S、G2和M)再回到静止。细胞周期的氧化还原控制的丧失可能导致异常增殖,这是各种人类病理学的标志。本文综述了支持氧化还原循环控制哺乳动物细胞周期的概念的文献,重点讨论了这种控制与增殖性疾病(包括癌症、伤口愈合、纤维化、心血管疾病、糖尿病和神经退行性疾病)的关系。我们假设,通过操纵细胞的氧化还原环境,重新建立细胞周期的氧化还原控制,可以缓解增殖性疾病的许多方面。
Cellular oxidation and reduction (redox) environment is influenced by the production and removal of reactive oxygen species (ROS). In recent years, several reports support the hypothesis that cellular ROS-levels could function as “second messengers” regulating numerous cellular processes, including proliferation. Periodic oscillations in the cellular redox environment, a redox cycle, regulate cell cycle progression from quiescence (G0) to proliferation (G1, S, G2, and M) and back to quiescence. A loss in the redox control of the cell cycle could lead to aberrant proliferation, a hallmark of various human pathologies. This review discusses the literature which supports the concept of a redox cycle controlling the mammalian cell cycle with an emphasis on how this control relates to proliferative disorders including cancer, wound healing, fibrosis, cardiovascular diseases, diabetes, and neurodegenerative diseases. We hypothesize that reestablishing the redox control of the cell cycle by manipulating the cellular redox environment could assuage many aspects of the proliferative disorders.
