摘要
目的研究不同非小细胞肺癌(NSCLC)细胞株中血管内皮生长因子受体-2(VEGFR-2)mRNA的表达情况。方法采用实时荧光定量PCR法检测人肺黏液表皮样癌NCI-H292细胞株、人肺腺癌NCI-H1299细胞株、人肺腺癌A549细胞株、人肺巨细胞癌95D细胞株和人肺鳞癌Calu-1细胞株中VEGFR-2 mRNA的表达。结果 Calu-1、NCI-H292、95D、NCI-H1299和A549细胞株中VEGFR-2 mRNA表达依次为1.213±0.134、1.008±0.164、0.754±0.088、0.582±0.171和0.121±0.026,差异有统计学意义(F=31.875,P=0.000)。Calu-1与NCI-H292细胞株间VEGFR-2 mRNA表达无统计学差异(P=0.080),NCI-H1299与95D细胞株间VEGFR-2 mRNA表达亦无统计学差异(P=0.137),其余细胞株间差异均有统计学意义(P均<0.05)。结论不同NSCLC细胞株中VEGFR-2 mRNA表达量不同,可能与不同肿瘤细胞的生物学行为有关。
Objective To investigate the expressions of vascular endothelial growth factor receptor 2 (VEGFR-2) mRNA in different lung cancer cell lines.Methods The expressions of VEGFR-2 mRNA in the human pulmonary mucoepidermoid carcinoma cell line NCI-H292,lung adenocarcinoma cell line NCI-H1299,lung adenocarcinoma cell line A549,lung giant cell carcinoma 95D and lung squamous carcinoma cell line Calu-1 were detected by real-time quantitative PCR (RT-PCR).Results The expressions of VEGFR-2 mRNA were 1.213 ± 0.134,1.008 ±0.164,0.754 ±0.088,0.582 ±-0.171 and 0.121 ±0.026 in Calu-1,NCI-H292,95D,NCI-H1299 and A549 cell lines,showing significant differences (F =31.875,P =0.000).No significant difference was observed in the expression of VEGFR-2 mRNA between Calu-1 and NCI-H292 (P =0.080) or between NCI-H1299 and 95D (P =0.137).Conclusion The expression of VEGFR-2 mRNA is diverse in different lung cancer cell lines,which is closed with the different biological behavior.
