Collagen prolyl 4-hydroxylase 2 predicts worse prognosis and promotes glycolysis in cervical cancer.

ABSTRACT: P4HA2 is one of collagen prolyl 4-hydroxylase (P4H) isoform and increased in several types of human cancer. However, the role of P4HA2 during cervical tumorigenesis remains largely unknown. Here, we report that the protein level of P4HA2 is significantly increased in cervical cancer tissues. Silencing of P4HA2 inhibits cervical cancer cell proliferation, colony formation and migration. We also demonstrate decreased glucose uptake and lactate production in P4HA2 knockdown cells. Mechanistically, P4HA2 promotes cervical cancer cell glycolysis through upregulation of PGK1 and LDHA. We find a positive correlation between P4HA2 and PGK1/LDHA expression in cervical cancer tissues. Importantly, high expression of P4HA2, PGK1 or LDHA has a significantly shorter overall survival period and the surv
