Gliomas stand out as highly predominant malignant nervous tumors and are linked to adverse treatment outcomes and short survival periods. Current treatment options are limited, emphasizing the need to identify effective therapeutic targets. The heterogeneity of tumors necessitates a personalized treatment approach with an effective grouping system. Meox1 has been implicated in promoting tumor progression in diverse cancers; nonetheless, its role in gliomas remains unelucidated.
MATERIAL/METHODS: to assess the expression of Meox1 protein in glioma tissues. Proliferation and invasion assays were conducted on wild-type and meox1-overexpressed glioma cells using the CCK8 and Transwell assays, respectively. The expression levels of meox1 and its related genes in gliomas were obtained from Chinese Glioma Genome Atlas (CGGA), along with the corresponding patient survival periods. LASSO regression modeling was employed to construct a scoring system for patients with gliomas, categorizing them into high-/low-risk groups. Additionally, a nomogram for predicting the survival period of patients with glioma was developed using multivariate logistic analysis.
We attempted, for the first time, to demonstrate heightened expression of Meox1 in glioma tumor tissues, correlating with significantly increased invasion and proliferation abilities of glioma cells following meox1 overexpression. The scoring system effectively stratified patients with glioma into high-/low-risk groups, revealing differences in the survival period and immunotherapy efficacy between the two groups. The integration of this scoring system with other clinical indicators yielded a nomogram capable of effectively predicting the survival period of individuals with gliomas.
Our study established a stratified investigation system based on the levels of meox1 and its related genes, providing a novel, cost-effective model for facilitating the prognosis prediction of individuals with glioma.
胶质瘤是高度占主导地位的恶性神经肿瘤,与不良的治疗结果和较短的生存期相关。目前的治疗选择有限,这凸显了识别有效治疗靶点的必要性。肿瘤的异质性需要采用个性化治疗方法以及有效的分组系统。Meox1已被证明在多种癌症中促进肿瘤进展;然而,其在胶质瘤中的作用仍未阐明。
材料/方法:评估Meox1蛋白在胶质瘤组织中的表达。分别使用CCK8和Transwell实验对野生型和过表达meox1的胶质瘤细胞进行增殖和侵袭实验。从中国胶质瘤基因组图谱(CGGA)获取胶质瘤中meox1及其相关基因的表达水平以及相应患者的生存期。采用LASSO回归模型为胶质瘤患者构建评分系统,将他们分为高/低风险组。此外,使用多因素逻辑回归分析开发了预测胶质瘤患者生存期的列线图。
我们首次尝试证明Meox1在胶质瘤肿瘤组织中表达升高,这与meox1过表达后胶质瘤细胞的侵袭和增殖能力显著增加相关。该评分系统有效地将胶质瘤患者分为高/低风险组,揭示了两组在生存期和免疫治疗疗效方面的差异。将该评分系统与其他临床指标相结合产生了一个能够有效预测胶质瘤患者生存期的列线图。
我们的研究基于meox1及其相关基因水平建立了一个分层研究系统,为促进胶质瘤患者的预后预测提供了一种新颖、经济有效的模型。
