Abstract
AIM: To investigate the effect of silencing of the caveolin-1 (cav-1) gene on the proliferation and migration of multidrug resistant gastric adenocarcinoma cells (SGC7901/ADR) and to explore the underlying mechanisms.
METHODS: A siRNA specific for the cav-1 gene was transfected into SGC7901/ADR cells using Lipofectamine 2000. The proliferation and migration of SGC7901/ADR cells were detected by MTT assay and transwell assay, respectively. The mRNA expression of cav-1 was determined by RT-PCR. The protein expression of Cyclin D1, Cyclin A1 and Cyclin E was determined by Western blot.
RESULTS: Compared with the control group, the mRNA expression of cav-1 was significantly decreased in SGC7901/ADR cells after transfection (P < 0.05). The proliferation and migration of SGC7901/ADR cells were inhibited significantly after cav-1 silencing. Additionally, the protein expression of Cyclin D1 and Cyclin A1 was obviously inhibited. However, silencing of cav-1 did not affect Cyclin E expression.
CONCLUSION: Silencing of the cav-1 gene inhibits the proliferation and migration of human gastric cancer SGC7901/ADR cells possibly by decreasing the expression of Cyclin D1 and Cyclin A1.
