MitoAMPK inhibits the Warburg effect by MZF1-SIRT6 with glycosis related genes in NSCLC.

ABSTRACT

MitoAMPK was proved to inhibit the Warburg effect, but the specific mechanisms on non-small-cell lung cancer remain unclear. Here, we selected SIRT6 and MZF1 to clarify the mechanism. By western blotting, quantitative polymerase chain reaction, the CCK-8 assay, and immunohistochemistry assays, we found SIRT6 expression was lower in NSCLC tissues and cell lines than normal tissues and cells. Moreover, SIRT6 could inhibit the Warburg effect by regulating glycolysis-related genes of SLC2A2, SLC2A4 and PKM2. Finally, we demonstrated the interaction between SIRT6 and MZF1 using ChIP-qPCR. In conclusion, mitoAMPK inhibits the Warburg effect by regulating the expression of the MZF1-SIRT6 complex.
