摘要
目的:观察生半夏、南星中药水提物对缺氧环境中人胃癌细胞株BGC823细胞HIF-1α蛋白表达和侵袭力的影响。方法:运用CoCl(2氯化钴)诱导BCG823细胞缺氧,使得细胞中HIF-1α蛋白表达升高.实验组加入生半夏、南星水提物对细胞进行预处理,然后在进行缺氧诱导。通过甲基噻唑基四唑法(MTT)检测细胞活性,使用Transwell检测细胞侵袭能力变化,RT-PCR、Western blotting分别检测HIF-1α mRNA及蛋白含量及变化。结果:生半夏、南星水提物能抑制人胃癌BGC823细胞的增殖;生半夏、南星水提物均能抑制缺氧诱导胃癌细胞的侵袭力,并且能降低HIF-1α mRNA及蛋白表达。结论:生半夏、南星水提物可抑制人胃癌BGC823细胞的增殖,抑制人胃癌BGC823细胞侵袭力,可能通过降低HIF-1α蛋白表达有关。
To investigate the effects of the enthanol and nanxing extract from Rhizome Pinelliae Preparata on hypoxiainducible -1 alpha protein expression and aggressive influence in human gastric cancer cells BGC823. Methods: COC12 (chlorinated cobalt) was used to induce BCG823 cytopathic hypoxia approach, which leads the increasing the expression of hypoxia-inducible -1 alpha. The cell viability was detected by MTT chromatometry and cell growth curve was generated; Transwell small room was used to detect cells attack ability, RT-PCR, Western blotting was use to detect hypoxia-inducible-l alpha mRNA expression and protein level. Results The extraction of enthanol and nanxing can inhibit the proliferation of cells BGC823 human cancer;The enthanol and nanxing extrac can inhibit the aggressive ability of cells BGC823 human cancer cells, the cause of which may be the decreasing of the expression of HIF-1 alpha mRNA and protein. Conclusion: Enthanol extract from Rhizome Pinelliae Preparata can inhibit the BGC823 cells proliferation and Restrain BGC823 human cancer cells aggressie influence by lowering hypoxia-inducible - 1 alpha mRNAand the protein exoression.
