Abstract

INTRODUCTION: Immune microenvironment and microRNAs serve as common predictors for diagnosis and prognosis of tumors. METHODS: Expression of 122 genes and 126 microRNAs in thymoma was obtained from TCGA database. The proportion of tumor-infiltrating cells was calculated, and IMRS was constructed. TREM2hi score was calculated before functional enrichment analysis on gene sets. RESULTS: IMRS3, TREM2hi score, and CD8+ T lymphocyte abundance were significantly different among WHO classifications. WHO classification, Masaoka staging, and miR-130b-5p, miR-1307-3p, miR-425-5p, CD8, CD68, and CCL18 expression were prognostic factors for relapse-free survival and overall survival. IMRS3 upregulation polarized macrophages into M2, which rejected CD8+ T and other effector lymphocytes to promote thymoma malignant progression. CONCLUSIONS: BRRS may present a novel immune-related microRNA signature for TET prognosis.

摘要

简介：免疫微环境和 microRNAs 可作为肿瘤诊断和预后的共同预测因子。 方法：从 TCGA 数据库中获取胸腺瘤中 122 个基因和 126 个 microRNAs 的表达情况。计算肿瘤浸润细胞的比例，并构建 IMRS。在对基因集进行功能富集分析之前，计算 TREM2hi 评分。 结果：IMRS3、TREM2hi 评分和 CD8+T 淋巴细胞丰度在 WHO 分类中存在显著差异。WHO 分类、Masaoka 分期、miR-130b-5p、miR-1307-3p、miR-425-5p、CD8、CD68 和 CCL18 的表达是无复发生存和总生存的预后因素。IMRS3 的上调使巨噬细胞向 M2 极化，排斥 CD8+T 和其他效应淋巴细胞，促进胸腺瘤恶性进展。 结论：BRRS 可能为 TET 的预后提供一种新的免疫相关 microRNA 特征。
