Effects of HMGA1 silence by RNA interference on the apoptosis and cell cycle of hepatocarcinoma cells / 中国免疫学杂志

ABSTRACT

Objective:To develop HMGA1-silencing SMMC-7721 cell and investigate its impacts on apoptosis and cell cycle in tumor cells.Methods:Constructing HMGA1-silencing SMMC-7721 cell through G418 selection of RNAi plasmid transfected cells;surveying the apoptosis,prliferation and cell cycle of the tumor cells by FACS and MTT.Results:Stable HMGA1-silencing cells were obtained successfully.The apoptosis percentage in RNAi group(29.46?3.04%) was significantly higher than that in the negative control (1.96?0.76%) or control (2.04?0.70%)within each P
