Phosphofructokinase-M inhibits cell growth via modulating the FOXO3 pathway in renal cell carcinoma cells.

ABSTRACT

Phosphofructokinase-M (PFKM) is a key enzyme in glycolysis. The expression and activity of PFKM is closely related to the occurrence and development of malignant tumors, but its role in the regulation of renal cell carcinoma (RCC) is still unknown. We found that the expression of PFKM was lower in RCC tumor tissue than in adjacent normal tissues, and that low expression of PFKM was related to the poor overall survival of RCC patients. In addition, our results showed that FOXO3 mediated PFKM inhibited the growth, migration and invasion of RCC cells, suggesting that PFKM is a protective factor for RCC.
