This study aimed to investigate the relationship between 90K expression with glioma malignancy and prognosis. Additionally, the enhancement effect of 90K in the Dendritic cell (DC) vaccine for Immunotherapy of glioblastoma (GBM) was evaluated .
The expression of 90K protein in glioma tissues was detected by western blot. The relationship between the 90K expression and the tumor grade as well as the prognosis of patients was further analyzed by mining TCGA and CGGA database. The concentration of IL-12p70 and IL-10 was detected by ELISA. T lymphocyte proliferation and lethal effect of cytotoxic T cell (CTL) were detected by CCK-8.
The expression of 90K was significantly higher in glioma than normal tissue and increased with tumor grade (P< 0.05). Higher 90K expression was observed in IDH wildtype glioma than IDH mutant and predicted worse overall survival for glioma patients. The concentration of IL-12p70 and IFN-γ was the highest in the Apoptosis U251-90K-DC group, in which group the ability to kill U251 cells by CTL was also the strongest.
90K was a useful biomarker for glioma malignancy and patient prognosis. The appearance of 90K enhanced the effect of Apoptosis U251-DC vaccine for immunotherapy of GBM.
本研究旨在探讨 90K 表达与胶质瘤恶性程度和预后的关系。此外,还评估了 90K 对树突状细胞(DC)疫苗免疫治疗胶质母细胞瘤(GBM)的增强作用。
通过 Western blot 检测胶质瘤组织中 90K 蛋白的表达。通过挖掘 TCGA 和 CGGA 数据库,进一步分析 90K 表达与肿瘤分级以及患者预后的关系。通过 ELISA 检测 IL-12p70 和 IL-10 的浓度。通过 CCK-8 检测 T 淋巴细胞增殖和细胞毒性 T 淋巴细胞(CTL)的致死效应。
90K 在胶质瘤中的表达明显高于正常组织,且随肿瘤分级升高而增加(P<0.05)。IDH 野生型胶质瘤中 90K 表达较高,且预测胶质瘤患者总体生存率较差。凋亡 U251-90K-DC 组中 IL-12p70 和 IFN-γ 的浓度最高,该组 CTL 杀伤 U251 细胞的能力也最强。
90K 是评估胶质瘤恶性程度和患者预后的有用生物标志物。90K 的出现增强了凋亡 U251-DC 疫苗免疫治疗 GBM 的效果。
