The clinical data showed that the expression level of STAT3 in ovarian cancer patients’ sera and tissues was positively correlated with those of GLUT1, LDHA, HK2 and HIF‐1α, but negatively with that of SIRT3These findings provide evidence that CT inhibited cellular glycolysis‐induced cell growth and proliferation through repression of STAT3/SIRT3/HIF‐1α signaling pathway, indicating that CT may be developed as a chemotherapeutic agent to treat ovarian cancer. Here, SLC2A1 is linked to ovarian carcinoma.
