摘要 目的通过研究夏枯草注射液(IPV)对人胰腺癌细胞系PANC-1的干预,观察其对癌细胞凋亡的影响,并探索其促进胰腺癌细胞凋亡的机制。方法以IPV干预PANC-1细胞,实验共分6组,1个空白对照组和5个药物干预组,干预组分别给予30、60、90、120、150mg/mL五个浓度梯度的IPV;RT-PCR检测细胞Bax与bcl-2的相对表达量的变化。结果随着IPV干预剂量的增加,胰腺癌细胞增殖明显受抑制具有统计学意义(P<0.05);使PANC-1细胞上调Bax和下调Bcl-2基因表达。结论夏枯草注射液可以促进胰腺癌细胞凋亡,其对PANC-1细胞的增殖抑制在一定剂量范围内有明显的浓度依赖性,该机制与夏枯草注射液调控胰腺癌细胞bcl-2家族基因表达相关,其可以使PANC-1细胞上调Bax和下调bcl-2基因表达,从而促使胰腺癌细胞凋亡、抑制增殖。
