BACKGROUND: Hepatocellular carcinoma (HCC) stands as a primary malignant liver tumor characterized by metabolic reprogramming. The oncogene c-Myc exerts substantial influence by driving the transcription of numerous genes. Empagliflozin (EMPA), a sodium-glucose cotransporter-2 inhibitor (SGLT2i), is widely used in the treatment of type 2 diabetes and has recently attracted attention for its potential anti-cancer effects. This study aims to unravel the complex interplay among c-Myc, EMPA, and the mammalian target of rapamycin (mTOR) in HCC development and progression. METHODS: HCC induction in mice utilized high-pressure hydrodynamic transfection of the c-Myc plasmid. QPCR and immunohistochemistry experiments were performed to detect the expression of SGLT2 in HCC tissues. In vivo experiments were conducted to corroborate the upregulation of SGLT2 following c-Myc transfection. In invo and vitro investigations were conducted to evaluate the anti-cancer effects of two SGLT2i: EMPA and canagliflozin (CANA). Network pharmacology, molecular docking analyses, CETSA experiments, and additional western blot experiments were used to reveal EMPA's interaction inhibition with mTOR. RESULTS: The study identified an increase in SGLT2 expression in HCC tissues as a result of c-Myc overexpression. In vitro experiments confirmed the upregulation of SGLT2 following c-Myc transfection. Notably, the administration of SGLT2i effectively curtailed liver cancer progression, and reduced hepatic fat accumulation in mice. EMPA exhibited significant suppression of cell proliferation in c-Myc-transfected cells. In vitro experiments unveiled EMPA's interaction and with inhibition the activation of mTOR. CONCLUSION: Our study highlights EMPA's potential as a therapeutic agent in delaying the development and progression of HCC.
