PFKFB3 regulated the growth and migration of ovarian cancer cells

Abstract

Ovarian cancer is one of the most common malignant tumors in female reproductive organs. Its incidence rate is second only to uterine body cancer and cervical cancer, posing a serious threat to women's health. Herein, we explored that PFKFB3 in cancer progression of Ovarian cancer and its underlying mechanism. All the serum samples from Ovarian cancer were collected by our hospital. PFKFB3 mRNA expressions in patients with Ovarian cancer and Ovarian cancer cell lines were up-regulated. PFKFB3 protein expressions in Ovarian cancer cells were induced. Ovarian cancer patients with high PFKFB3 expression had lower survival rate. PFKFB3 gene promoted cell proliferation and EDU cells, and increased cell metastasis of Ovarian cancer. Si-PFKFB3 reduced cell proliferation and EDU cells, and decreased cell metastasis of Ovarian cancer. PFKFB3 gene up-regulation reduced caspase-3/9 activity levels of Ovarian cancer. Si-PFKFB3 also promoted caspase-3/9 activity levels of Ovarian cancer. PFKFB3 gene promoted Warburg effect progression of Ovarian cancer. PFKFB3 gene reduced NLRP3-induced pyroptosis of Ovarian cancer. PFKFB3 suppressed NLRP3 expression. NLRP3 was one target spot for PFKFB3 on pyroptosis of Ovarian cancer. Taken together, we conclude that PFKFB3 suppressed NLRP3 axis to reduce pyroptosis and increase Warburg effect progression of Ovarian cancer, and provide molecular insight into the mechanisms by which the PFKFB3 regulates pyroptosis of Ovarian cancer.
