Gliomas are primary intracranial space lesions with a high mortality rate. Current treatments for glioma are very limited. Recently, immunotargeted therapy of the glioma microenvironment has been developed. Members of the 70 kDa heat shock protein (HSP70) family are involved in the development of many tumors and immunity. HSPA6 protein belongs to the HSP70 family; However, the biological function of this protein in gliomas has yet to be evaluated. In the present study, a range of analyses, involving protein networks, survival, clinical correlation, and function, revealed that the expression of HSPA6 was negatively correlated with clinical prognosis and closely associated with immunity, invasion, and angiogenesis. Quantitative protein analysis confirmed that HSPA6 was expressed at high levels in patients with glioblastoma. Vitro experiments further verified that HSPA6 enhanced the malignant progression of glioma cells by promoting proliferation, invasion and anti-apoptosis. We also found that HSPA6 was closely correlated with genomic variations and tumor microenvironment. Collectively, we demonstrated that HSPA6 may represent a new therapeutic target to improve the prognosis of patients with gliomas.
胶质瘤是原发性颅内占位性病变,死亡率很高。目前针对胶质瘤的治疗方法非常有限。最近,已开展了胶质瘤微环境的免疫靶向治疗。70 kDa热休克蛋白(HSP70)家族成员参与多种肿瘤的发生发展及免疫过程。HSPA6蛋白属于HSP70家族;然而,该蛋白在胶质瘤中的生物学功能尚未得到评估。在本研究中,一系列涉及蛋白质网络、生存、临床相关性和功能的分析表明,HSPA6的表达与临床预后呈负相关,且与免疫、侵袭和血管生成密切相关。定量蛋白质分析证实,HSPA6在胶质母细胞瘤患者中高表达。体外实验进一步证实,HSPA6通过促进增殖、侵袭和抗凋亡增强胶质瘤细胞的恶性进展。我们还发现,HSPA6与基因组变异和肿瘤微环境密切相关。总体而言,我们证明HSPA6可能是改善胶质瘤患者预后的一个新的治疗靶点。
