由于细胞凋亡和自噬机制之间相互作用的复杂性,自噬在治疗癌症和其他疾病方面的治疗潜力一直受到悖论的困扰。最简单的问题是,自噬如何既是细胞死亡的保护者,又是细胞死亡的刽子手,这仍然是一个充满争议的话题。阐明这些过程之间的分子相互作用将有助于我们了解自噬如何调节细胞死亡,自噬是否真的是一种细胞死亡机制以及这些功能是如何被调节的。我们认为,尽管自噬和细胞凋亡之间存在许多联系,但其中一个过程控制另一个过程的强烈因果关系尚未得到充分证明。了解何时以及如何从治疗上调节自噬取决于对这些联系的理解。
The therapeutic potential of autophagy for the treatment cancer and other diseases is beset by paradoxes stemming from the complexity of the interactions between the apoptotic and autophagic machinery. The simplest question of how autophagy acts as both a protector and executioner of cell death remains the subject of substantial controversy. Elucidating the molecular interactions between the processes will help us understand how autophagy can modulate cell death, whether autophagy is truly a cell death mechanism and how these functions are regulated. We suggest that despite many connections between autophagy and apoptosis, a strong causal relationship wherein one process controls the other, has not been adequately demonstrated. Knowing when and how to modulate autophagy therapeutically depends on understanding these connections.
