title: PEBP4 gene expression and its significance in invasion and metastasis of non-small cell lung cancer.
abstract: The goal of this study was to investigate the function of phosphatidylethanolamine-binding protein 4 (PEBP4) in invasion and metastasis of non-small cell lung cancer (NSCLC). PEBP4 mRNA and protein expression in 56 cases of NSCLC tissues were detected using RT-PCR and Western blot, and the relationship between PEBP4 expression and invasion and metastasis of NSCLC was analyzed. The change in the invasive ability of human NSCLC cell line HCC827 was observed after knocking down PEBP4 expression using RNA interference. PEBP4 mRNA and protein expression in cancer tissues of patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis (p < 0.05). PEBP4 expression significantly decreased in HCC827 cells after transfection with PEBP4 siRNA (p < 0.01), and the number of HCC827 cells that migrated through Transwell chambers was significantly lower than that of non-transfected control and transfected control cells (p < 0.01). PEBP4 over-expression may promote the invasion and metastasis of NSCLC.
