Abstract

To investigate the biological functions of reversion-inducing cysteine-rich protein with Kazal motifs (RECK) over-expression in pancreatic cancer cell line Panc-1. This study was carried out in the Department of General Surgery, First Affiliated Hospital of Soochow University, Suzhou, Jiangsu, China from January to September 2009. The design of the study was to construct a recombinant lentivirus carrying the RECK gene (LV-RECK) to be used to infect Panc-1 cells, and investigate the biological functions of RECK in pancreatic cancer in vitro. The RECK expression was measured by real-time polymerase chain reaction (PCR) and Western blotting. Cell proliferation and apoptosis were examined by 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry. The ability of invasion was detected using Transwell chambers. The expression and activity of matrix metalloproteinase (MMP)-2 and matrix metalloproteinase-9 (MMP-9) was measured by real-time PCR, Western blotting, and gelatin zymography. We successfully constructed LV-RECK and proved it can over-express the RECK gene in Panc-1 cells. The RECK over-expression potently suppressed the invasion ability of Panc-1 cells in vitro without affecting cell proli...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
