Immunotherapy is an effective treatment for many cancer types. However, YTHDF2 effects on the prognosis of different tumors and correlation with tumor immune infiltration are unclear. Here, we analyzed The Cancer Genome Atlas and Gene Expression Omnibus data obtained through various web-based platforms. The analyses showed that YTHDF2 expression and associated prognoses may depend on cancer type. High YTHDF2 expression was associated with poor overall survival in lower-grade glioma (LGG). In addition, YTHDF2 expression positively correlated with expression of several immune cell markers, including PD-1, TIM-3, and CTLA-4, as well as tumor-associated macrophage gene markers, and isocitrate dehydrogenase 1 in LGG. These findings suggest that YTHDF2 is a potential prognostic biomarker that correlates with LGG tumor-infiltrating immune cells.
免疫疗法是许多癌症类型的有效治疗方法。然而,YTHDF2对不同肿瘤预后的影响以及与肿瘤免疫浸润的相关性尚不清楚。在此,我们分析了通过各种基于网络的平台获得的癌症基因组图谱和基因表达综合数据库数据。分析表明,YTHDF2的表达及相关预后可能取决于癌症类型。YTHDF2高表达与低级别胶质瘤(LGG)的总体生存率低相关。此外,YTHDF2表达与几种免疫细胞标志物的表达呈正相关,包括PD-1、TIM-3和CTLA-4,以及LGG中的肿瘤相关巨噬细胞基因标志物和异柠檬酸脱氢酶1。这些发现表明,YTHDF2是一种潜在的预后生物标志物,与LGG肿瘤浸润免疫细胞相关。
