ULK1 and esophageal squamous cell carcinoma: In our study, we elucidate a novel mechanism of the NF-κB/AMPK/mTOR/ULK1 pathway in CPT-induced protective autophagy in esophageal cancer cells, which provides a sound rationale for combinational anti-ESCC therapy with CPT and inhibition AMPK/ULK1 pathway.
