Enhanced glycolysis is a common trait of many types of human cancers. This study was to detect the expression pattern of three regulatory enzymes during glycolysis in esophageal squamous cell carcinoma (ESCC) and to investigate their correlation with patients-outcome based on banked pathology material. A total of 141 surgically resected specimens of primary ESCC patients without prior treatments were retrospectively recruited from the First Affiliated Hospital of Wenzhou Medical College Hospital from 2007 to 2009. Expression of HK1, PFKB, and PKM2 in ESCC specimens was analyzed by immunohistochemical staining and Western blotting analysis. HK1-shRNA was used to knock down HK1 expression in ESCC cells, and the functional significance was assessed by CCK8 assay. It was found that the expression of two glycolytic enzymes, HK1 and PKM2, was associated with disease progression, invasion, and poor survival of patients with ESCC. Silence of HK1-inhibited cell proliferation in vitro and suppressed phospho-S6 kinase expression. Our findings suggest that activation of key enzymes in glycolysis might serve as potential therapeutic targets and/or prognostic factors for patients with ESCC.
