摘要: 目的:研究尖吻蝮蛇毒抑瘤组分I( AAVC-I) 对人肺癌A549细胞增殖抑制及凋亡的作用。方法:采用MTT法检测不同浓度的AAVC-I对A549细胞的 24 h 与 48 h 抑制率;应用HE染色、Hoechst33258荧光染色,从形态学观察细胞凋亡;采用免疫组化的方法,检测bax蛋白表达的变化。结果:MTT显示,AAVC-I能抑制A549细胞增殖,呈时间和剂量依赖性;AAVC-I处理 24 h 后,镜下可见细胞核固缩,核深染及凋亡小体;免疫组化显示,随药物浓度增加,平均光密度值呈递增趋势,表明bax蛋白表达相应上调。结论:尖吻蝮蛇毒抑瘤组分I对人肺癌A549细胞具有抑制作用,并诱导其凋亡,可能与bax表达上调有关。

Abstract: AIM: To research the inhibitory and apoptosis effect of anti-tumor component I(AAVC-I) from Agkistrodon acutus venom on human lung cancer A549 cells.METHODS: The inhibition rate after 24 h and 48 h with different concentrations of AAVC-I on A549 was detected by MTT method. The form of apoptosis was observed by HE staining and Hoechst fluorescent staining. The expression change of bax protein after AAVC-I treatment was detected by immunohistochemical staining method.RESULTS: MTT showed that AAVC-I could inhibit the proliferation of A549 in a time- and dose-dependent manner. The form of apoptosis in A549 could be observed by ordinary microscope and fluorescent staining when treated with AAVC-I for 24 h. Immunohistochemical staining showed that the mean light density had a trend of increase in dose dependency, which indicated that the expression of bax increased accordingly.CONCLUSION: AAVC-I had an inhibitory effect on A549 cell proliferation, apoptosis promoting effect as well, which maybe related to the increase of bax expression.
