lncRNA TRHDE-AS1 Correlated with Genomic Landscape and Clinical Outcome in Glioma

Abstract

The role of lncRNA in cancer development has received more and more attention in research. A variety of lncRNAs are associated with the occurrence and development of glioma. However, the role of TRHDE-AS1 in glioma is still unknown. In this study, we explored the role of TRHDE-AS1 in glioma through bioinformatic methods. We first identified an association between TRHDE-AS1 and tumor prognosis in pan-cancer analysis. Subsequently, the expression levels of TRHDE-AS1 in various clinical types of glioma were compared, and significant differences were found in pathological classification, WHO classification, molecular classification, IDH mutation, and age stratification. We analyzed the genes co-expressed with TRHDE-AS1 in glioma. In the functional analysis of TRHDE-AS1, we found that TRHDE-AS1 may be involved in the regulation of synapse-related functions. In glioma cancer driver gene correlation analysis, it was also found that TRHDE-AS1 was significantly correlated with the expression levels of multiple driver genes such as TP53, BRAF, and IDH1. By comparing the mutant profiles of the high and low TRHDE-AS1 groups, we also found that there may be differences in TP53 and CIC gene mutations in low-grade gliomas. Subsequent correlation analysis between TRHDE-AS1 and glioma immune microenvironment showed that the expression level of TRHDE-AS1 was correlated with a variety of immune cells. Therefore, we believe that TRHDE-AS1 is involved in the occurrence and development of glioma and has the ability to predict the prognosis of glioma as a biomarker of glioma.

KLRB1 expression is associated with lung adenocarcinoma prognosis and immune infiltration and regulates lung adenocarcinoma cell proliferation and metastasis through the MAPK/ERK pathway

“…Another study investigated the relationship between the lncRNA TRHDE-AS1 and the development of gliomas. The prognostic analysis, differential expression analysis, potential pathway mechanism analysis, mutation analysis and immune infiltration analysis of the expressed genes indicated that this lncRNA has great potential in guiding clinical prognosis prediction and future therapeutic decisions ( 21 ). According to database analysis, INHA is a diagnostic and prognostic marker for LUAD, and high expression of this molecule is a risk factor for a poor prognosis in LUAD patients and promotes LUAD cell proliferation and invasion in vitro and in vivo by activating the EGFR pathway ( 22 ).…”
