Autophagy is a self-destructive process that occurs in the cells during abnormal conditions like protein aggregation due to misfolding, nutrient deprivation, damage to vital cell organelles, pathogenic infections, and during cancer. Typically, autophagy plays a key role in the renovation of new cells by balancing the equilibrium between cell death and cell renewal. Dysregulation of autophagy has a profound effect on protein turnover, mitochondrial homeostasis, clearance of damaged organelles, and cellular metabolism, which lead to neurodegenerative, metabolic, and proliferative diseases. Despite its antitumorigenic role, autophagy can promote cell proliferation by enhancing chemotherapeutic resistance in liver cancer. In the present review, we provide a comprehensive overview and discussion on the role of autophagy in the drug-resistant mechanisms of liver cancer.
