临床上相关的胶质瘤亚型，如胶质瘤-CpG岛甲基化表型(G-CIMP)，已被表观遗传学定义。本研究探讨了长非编码RNA与预后不良的G-CMIP-Low表型和预后良好的G-CMIP-High表型之间的关系。研究了lncRNAs与mRNAs和miRNAs的功能关联，以推测攻击性表型的影响因素。对来自TCGA泛胶质瘤研究的250个样本的RNA-SEQ数据进行了分析，以量化LncRNA和mRNAs(GENCODE V28)，以寻找G-CIMP-low和G-CIMP-High表型之间的差异表达。通过独创性路径分析对差异表达的lncRNAs进行功能解释。Spearman等级相关估计lncRNA、miRNA和mRNA提名的具有可能的miRNA海绵功能的差异lncRNA。我们鉴定了4371个差异表达的特征( = 3705； = 666；FDR ≤ 5%)。由此，蛋白质编码基因tp53被鉴定为差异lncRNAs pandar和pvt1的上游调节基因(p = 0.0237)，并在“肿瘤的发展”中被检测到(p = 0.0176)。两个lncRNAs(HCG11，Part 1)与342个mRNAs呈正相关，在调整其中任何一个靶miRNAs：hsa-miR-490-3p、hsa-miR-129-5p后，它们的相关性估计值降低。这表明HCG11和Part 1可能具有海绵功能。这些发现确定了具有与G-CIMP表型相关的致癌特征的差异lncRNA。需要进一步的研究和对照实验来确认分子间的关系。网上版载有补充材料，可在10.1186/s12967-021-02844-z查阅。
Clinically relevant glioma subtypes, such as the glioma-CpG island methylator phenotype (G-CIMP), have been defined by epigenetics. In this study, the role of long non-coding RNAs in association with the poor-prognosis G-CMIP-low phenotype and the good-prognosis G-CMIP-high phenotype was investigated. Functional associations of lncRNAs with mRNAs and miRNAs were examined to hypothesize influencing factors of the aggressive phenotype. RNA-seq data on 250 samples from TCGA’s Pan-Glioma study, quantified for lncRNA and mRNAs (GENCODE v28), were analyzed for differential expression between G-CIMP-low and G-CIMP-high phenotypes. Functional interpretation of the differential lncRNAs was performed by Ingenuity Pathway Analysis. Spearman rank order correlation estimates between lncRNA, miRNA, and mRNA nominated differential lncRNA with a likely miRNA sponge function. We identified 4371 differentially expressed features (mRNA = 3705; lncRNA = 666; FDR ≤ 5%). From these, the protein-coding gene TP53 was identified as an upstream regulator of differential lncRNAs PANDAR and PVT1 (p = 0.0237) and enrichment was detected in the “development of carcinoma” (p = 0.0176). Two lncRNAs (HCG11, PART1) were positively correlated with 342 mRNAs, and their correlation estimates diminish after adjusting for either of the target miRNAs: hsa-miR-490-3p, hsa-miR-129-5p. This suggests a likely sponge function for HCG11 and PART1. These findings identify differential lncRNAs with oncogenic features that are associated with G-CIMP phenotypes. Further investigation with controlled experiments is needed to confirm the molecular relationships. The online version contains supplementary material available at 10.1186/s12967-021-02844-z.
