摘要: The objectives of the present study are to explore role pyruvate kinase isoenzyme type M2 (PKM2) in progression Kazakh's esophageal squamous cell carcinoma (ESCC) Xinjiang, China, and clarify mechanism PKM2 malignant phenotype. expression was examined using immunohistochemistry (IHC) 101 matched pairs ESCC normal adjacent tissues (NATs) enzyme-linked immunosorbent assay (ELISA) 35 serum samples 8 healthy subjects. To investigate mechanism, small interfering RNA (siRNA)-PKM2 transfected into cells. Cell migration invasion were evaluated by wound healing Transwell assays. Apoptosis cycle analyzed flow cytometry (FCM). significantly higher (77.2 %, 78/101) compared with NAT (P = 0.003) also patients (78.84 ng/mL) subjects (13.55 ng/mL) (P = 0.001). Patients overexpression had a poor prognosis (P = 0.032). After knockdown PKM2, proliferation, migration, reduced (P = 0.001), apoptosis increased arrested at G1 phase. correlated worse outcome ESCC. Furthermore, involved promoting proliferation suppressing apoptosis, accelerating invasion, influencing cycle. could be potential biomarker for molecular classification
