Macroautophagy: protector in the diabetes drama?

abstract：:Hepatocellular carcinoma (HCC) is among the most lethal and prevalent cancers in the human population. The initiation and progression of HCC is closely associated with chronic liver inflammation. Recent research indicates that nonhomologous end joining (NHEJ), one of the DNA repair mechanisms, autophagy and senescence...
