自噬是一种分解代谢过程,它可以转化长寿的蛋白质和细胞器,并有助于细胞和生物体在压力下的生存。目前的癌症治疗包括化疗和放疗已知会诱导肿瘤细胞内的自噬。因此,这是一个有吸引力的过程,在癌症治疗中靶向,因为有安全的,临床上可用的药物,已知既抑制和刺激自噬。然而,自噬的积极和消极影响相互矛盾,目前还没有关于如何操纵自噬以改善临床结果的共识。对自噬进行仔细和严格的评估,重点是如何将实验室发现转化为相关的临床治疗,仍然是改善恶性疾病患者临床结局的重要方面。
Autophagy is a catabolic process that turns over long-lived proteins and organelles and contributes to cell and organism survival in times of stress. Current cancer therapies including chemotherapy and radiation are known to induce autophagy within tumor cells. This is therefore an attractive process to target during cancer therapy as there are safe, clinically available drugs known to both inhibit and stimulate autophagy. However, there are conflicting positive and negative effects of autophagy and no current consensus on how to manipulate autophagy to improve clinical outcomes. Careful and rigorous evaluation of autophagy with a focus on how to translate laboratory findings into relevant clinical therapies remains an important aspect of improving clinical outcomes in patients with malignant disease.
