目的:探讨表皮生长因子受体抑制剂吉非替尼对敲低膜联蛋白A7后的人肝癌细胞株HepG2细胞增殖的影响,为肝癌的分子靶向治疗提供实验依据。方法:将细胞分为吉非替尼组、siRNA转染、siRNA转染+吉非替尼、转染阴性对照组和空白对照组,用脂质体转染法靶向将ANXA7的siRNA转染入HepG2细胞,在转染后6h在siRNA转染组和siRNA转染组+吉非替尼组加入一定浓度的吉非替尼,加药后72h进行MTT实验以检测细胞增殖活力,从而计算增殖抑制率。结果:MTT检测得知, siRNA转染组、吉非替尼组和siRNA转染+吉非替尼组,对细胞增殖有明显的抑制作用,较对照组差别有统计学意义( P<0.05)。结论:吉非替尼对敲低ANXA7后的HepG2细胞的增殖具有更为明显的抑制作用。
目的:探討錶皮生長因子受體抑製劑吉非替尼對敲低膜聯蛋白A7後的人肝癌細胞株HepG2細胞增殖的影響,為肝癌的分子靶嚮治療提供實驗依據。方法:將細胞分為吉非替尼組、siRNA轉染、siRNA轉染+吉非替尼、轉染陰性對照組和空白對照組,用脂質體轉染法靶嚮將ANXA7的siRNA轉染入HepG2細胞,在轉染後6h在siRNA轉染組和siRNA轉染組+吉非替尼組加入一定濃度的吉非替尼,加藥後72h進行MTT實驗以檢測細胞增殖活力,從而計算增殖抑製率。結果:MTT檢測得知, siRNA轉染組、吉非替尼組和siRNA轉染+吉非替尼組,對細胞增殖有明顯的抑製作用,較對照組差彆有統計學意義( P<0.05)。結論:吉非替尼對敲低ANXA7後的HepG2細胞的增殖具有更為明顯的抑製作用。

Objective:To explore the effect of EGFR inhibitor gefitinib on proliferation of the annexin A7 knockdown HepG2 cell,and to provide the evidence for potential molecular target therapy in the HCC clinical treatment.Method:The HepG2 cells were divided into gefitinib group,a siRNA transfection group, siRNA transfection combined gefitinib group,negative group and control group.The siRNA was transfected in-to HepG2 cells by lipofectamine transfection method.Six hours after transfection,added a certain concentra-tion of gefitinib into siRNA transfection group and siRNA transfection combined gefitinib group.Seventy-two hours after adding gefitinib,MTT assay was used to detect proliferation activity,and calculation the cell prolif-eration inhibition rate.Result:MTT assay showed that proliferation of the group of siRNA transfection, ge-fitinib and siRNA transfection combined gefitinib decreased significantly(P<0.05).Conclusion: Gefitinib can inhibit proliferation of ANXA7 knockdown HepG2 cells.
