Stem cell pluripotency and differentiation are global processes regulated by several pathways that have been studied intensively over recent years. Nitric oxide (NO) is an important molecule that affects gene expression at the level of transcription and translation and regulates cell survival and proliferation in diverse cell types. In embryonic stem cells NO has a dual role, controlling differentiation and survival, but the molecular mechanisms by which it modulates these functions are not completely defined. NO is a physiological regulator of cell respiration through the inhibition of cytochrome c oxidase. Many researchers have been examining the role that NO plays in other aspects of metabolism such as the cellular bioenergetics state, the hypoxia response and the relationship of these areas to stem cell stemness.
干细胞的多能性和分化是由多个途径调控的整体过程,近年来对这些途径进行了深入研究。一氧化氮(NO)是一种重要分子,它在转录和翻译水平上影响基因表达,并调节多种细胞类型中的细胞存活和增殖。在胚胎干细胞中,NO具有双重作用,控制分化和存活,但其调节这些功能的分子机制尚未完全明确。NO通过抑制细胞色素c氧化酶,是细胞呼吸的生理调节因子。许多研究人员一直在研究NO在代谢的其他方面所起的作用,如细胞生物能量状态、缺氧反应以及这些领域与干细胞干性的关系。
