Abstract:
OBJECTIVETo explore the effect of c-met ribozyme transfection on biological behavior of gastric carcinoma cells.
METHODSU1/met292 plasmid containing c-met ribozyme gene was transfected into L2 subline of SGC-7901 gastric cell line, and the proliferative ability, distribution of cell cycle, protein expression of VEGF and c-met, as well as the potential of liver metastasis of the transfected subline were determined.
RESULTSThere were no significant difference in proliferative ability, distribution of cell cycle between the transfected cells and the control cells. The protein expression of VEGF and c-met, as well as the liver metastatic potential significantly decreased in the transfected cells than those in the control cells (P< 0.05).
CONCLUSIONThe liver metastatic potential of c-met positive gastric cancer cells may be prevented by inhibiting c-met expression.
