HK2 and ovarian cancer: Correlation analysis indicated that TRPM7 expression levels in ovarian cancer tissues were positively correlated with HK2 (P < 0.01) and PDK1 (P < 0.01), but negatively correlated with IDH3B (p < 0.01) and UQCRC1 in this population (P < 0.05, Fig. 3B), supporting the notion that TRPM7 promotes glycolysis in ovarian cancer.
