目的在细胞学层次上研究γ-IFN对星形细胞肿瘤HLA-G mRNA表达的影响.方法原代细胞培养成功的基础上,用不同浓度γ-IFN处理,应用RT-PCR检测HLA-G mRNA表达水平的变化.结果γ-IFN处理后,HLA-G基因表达阴性的肿瘤细胞仍未见HLA-G mRNA的表达;不同浓度γ-IFN均可上调HLA-G基因表达阳性肿瘤细胞的HLA-G mRNA水平,并呈刑量依赖关系.结论 γ-IFN可以上调HLA-G基因阳性表达肿瘤细胞的HLA-G基因表达.

Objective To study the effects of γ-IFN on the expression of HLA-G mRNA in primary cultured astrocytoma cells. Methods Different concentrations of γ-IFN were added to primary cultured cells, and HLA-G mRNA were detected by RT-PCR. Results After γ-IFN treatment, HLA-G mRNA can not be determined from HLA-G originally negative astrocytoma cells. The expression of HLA-G are up - regulated in all original HLA-G positive astrocytoma cells in a dose-dependent manner. Conclusion γ-IFN can increase the ex-pression of HLA-G gene in the primary cultured astrocytoma cells which HLA - G are originally positive.
