Progress on association between autophagy and cancer / 浙江大学学报·医学版

ABSTRACT

Autophagy is an evolutionarily well conserved cellular catabolic process.Cellular proteins and organelles are engulfed to autophagosomes and eventually delivered to lysosomes for degradation. Autophagy is closely associated with a variety of human diseases especially cancer. At present, it has been widely accepted that autophagy is a "double-edged sword" in cancer it blocks tumorigenesis at the early stage, while it facilitates tumor development at the promotion and progression stage. Moreover, autophagy can be induced by chemotherapy and radiotherapy, which is generally play a pro-survival function. Thus, autophagy is an important target for cancer therapy, and suppression of autophagy to enhance the efficacy of cancer therapeutic agents is a novel strategy in cancer therapy under active clinical trials.
