摘要
在体外培养的人非小细胞肺癌A549细胞、人胃腺癌BGC-823细胞、人结肠癌HCT116细胞、人肝癌Hep 3B细胞、人宫颈癌Hela细胞中加入不同浓度的酵母异源表达的LZ-8或FIP-tvc,培养24 h后显微镜下观察细胞形态变化,并用CCK8试剂盒检测细胞存活率,以用来检测灵芝免疫调节蛋白LZ-8及云芝免疫调节蛋白FIP-tvc对几种癌细胞生长抑制能力.结果显示,LZ-8和FIP-tvc在5~10μg/mL浓度时使A549、BGC-823、Hela和Hep 3B细胞贴壁性变差,且CCK8结果显示前3种细胞的存活率有不同程度的降低(80%~95%存活率),而在20μg/mL浓度时FIP-tvc对Hep 3B细胞的存活率开始有明显抑制效果(89%存活率),但对HCT 116细胞的形态无影响,对其存活率也无抑制作用.
In this paper,the morphological changes of human non-small cell lung cancer cell line A549,human gastric adenocarcinoma cell line BGC-823,human colon cancer cell line HCT 116,human liver cancer cell line Hep 3 B and human cervical carcinoma cell line Hela were observed after culturing with LZ-8 or FIP-tvc for 24 hours,and the viability of these cell lines was further analyzed with CCK8 kit to analyze the inhibitory effect of LZ-8 from Ganoderma lucidum and FIP-tvc from Trametes versicolor to these cancer cell lines. The results showed that the cell adherence of A549,BGC-823,Hela and Hep 3 B was significantly inhibited by LZ-8 and FIP-tvc at 5-10 μg/mL,and the viability of the first three cell lines was simultaneously inhibited and analyzed with CCK8 kit(80%-95%),but the inhibitory effect of FIP-tvc to the viability of Hep 3 B was appeared when the concentration was reached to20 μg/mL(89%). While morphology of HCT 116 was not changed and its viability was also not inhibited by LZ-8 or FIP-tvc at any test concentrations.
