Abstract:
Objective To investigate cell proliferation and invasiveness of cervical cancer HeLa229 cell after knockdown of NF-?B signaling pathway by P65 siRNA.Methods RNA interference was employed for specific inhibition of the expression of P65.HeLa229 cell was divided into transfected group and untransfected group.Cell viability was detected by MTT after the HeLa229 cells were transfected with or without P65 siRNA for 24,48,72 h.The sensitivity to 5-Fu of the HeLa229 cell,transfected with or without P65 siRNA,was evaluated also by MTT.Boyden chamber experiment in vitro was used to detect the invasion of HeLa229 cell.Results P65 siRNA inhibited the cell proliferation as compared with the untransfected cells.Proliferations of both cells transfected with and without P65 siRNA were inhibited in a concentration-dependent manner,while at the same concentration of 5-Fu the viability of transfected HeLa229 cells was significantly suppressed(P
