Aims: Glycolysis is an important process for cervical carcinoma development. Previous studies have indicated that stress-induced phosphoprotein 1 (STIP1) is associated with development of multiple tumors. Nevertheless, the role and mechanism of STIP1 in glycolysis of cervical carcinoma remain unclear. Main methods: The association between STIP1 and survival probability and the correlation between STIP1 expression and pyruvate kinase M2 (PKM2) as well as lactate dehydrogenase isoform A (LDHA) levels in cervical carcinoma were analyzed via The Cancer Genome Atlas (TCGA). The expression of STIP1, PKM2, LDHA, and cytochrome c (Cyt C) was measured via western blot or quantitative reverse transcription polymerase chain reaction. Cell viability and apoptosis were examined via cell counting kit 8 and flow cytometry, respectively. Glycolysis was assessed via detection of glucose consumption and lactate production. The protein involved in the Wnt/beta-catenin pathway was measured via western blot. Key findings: STIP1 abundance was elevated in cervical carcinoma cells. High expression of STIP1 indicated poor survival probability. Knockdown of STIP1 inhibited cervical carcinoma cell viability and promoted apoptosis. STIP1 expression was positively correlated with PKM2 and LDHA levels in cervical carcinoma. Silence of STIP1 inhibited glycolysis and decreased PKM2 and LDHA expression. Down-regulation of STIP1 repressed the Wnt/beta-catenin pathway. Overexpression of beta-catenin reversed the effect of STIP1 silence on viability, apoptosis, glycolysis, and levels of PKM2 and LDHA. Significance: STIP1 knockdown suppressed glycolysis in cervical carcinoma by inhibiting PKM2 and LDHA expression and activation of the Wnt/beta-catenin pathway.
