Abstract:
Objective To investigate the proliferation and invasion of human pancreatic cancer cells after Stat1 gene silenced or enhanced and to explore the possible mechanisms.Methods BxPC-3 cells were divided to three groups: Stat1 group transfected with specific Stat1 plasmid, Si Stat1 group transfected with specific Stat1 small interfering RNA (siRNA), and control group.Western blot was used to detect the expression of Stat1, VEGF, MMP-2 and MMP-9 in BxPC-3 cells.MTT method was used to detect the proliferation of BxPC-3 cells.Transwell was used to detect the invasion of BxPC-3 cells.Results The proliferation and invasion were significantly enhanced in pancreatic cancer cells after Stat1 gene silenced, and the expression of VEGF, MMP-2 and MMP-9 was increased.The proliferation and invasion were significantly decreased in pancreatic cancer cells after Stat1 gene enhanced.Conclusions Stat1 inhibits the proliferation and invasion of pancreatic cancer cells.VEGF,MMP-2 and MMP-9 possibly play a role in this process.
