Glioblastoma is the most malignant and prevalent brain tumor in humans. It is composed of heterogenic abnormal astroglial cells that avoid differentiation, maintain proliferation, and hardly commit apoptosis. N-(4-Hydroxyphenyl)retinamide (4-HPR) induced astrocytic differentiation and increased sensitivity to interferon-gamma (IFN-gamma) for apoptosis in human glioblastoma A172, LN18, and SNB19 cells. Combination of 4-HPR and IFN-gamma significantly inhibited human telomerase reverse transcriptase (hTERT), cyclin dependent kinase 2 (CDK2), and survivin to up-regulate caspase-8, caspase-9, and caspase-3 for increasing apoptosis in all glioblastoma cell lines. Hence, combination of 4-HPR and IFN-gamma should be considered for controlling growth of different human glioblastoma cells.
胶质母细胞瘤是人类最恶性且最常见的脑肿瘤。它由异质性异常星形胶质细胞组成,这些细胞逃避分化、维持增殖且几乎不发生凋亡。N-(4-羟基苯基)视黄酸(4-HPR)诱导人胶质母细胞瘤A172、LN18和SNB19细胞发生星形胶质细胞分化,并增加对干扰素-γ(IFN-γ)诱导凋亡的敏感性。4-HPR与IFN-γ联合使用可显著抑制人端粒酶逆转录酶(hTERT)、细胞周期蛋白依赖性激酶2(CDK2)和生存素,上调半胱天冬酶-8、半胱天冬酶-9和半胱天冬酶-3,从而增加所有胶质母细胞瘤细胞系中的凋亡。因此,应考虑将4-HPR与IFN-γ联合使用来控制不同人胶质母细胞瘤细胞的生长。
