N6-Methylandenosine-Related lncRNAs are Potential Biomarkers for Predicting the Overall Survival Rate of Patients Bladder Cancer

Abstract Background: The prognostic value of N6-methylandenosine-related long non-coding RNAs (m6A-related lncRNAs) was investigated in 414 bladder cancer (BLCA) and 19 normal bladder tissue samples from The Cancer Genome Atlas (TCGA) datasets. Methods: We implemented Pearson correlation analysis to explore the lncRNAs associated with m6A, and then performed univariate Cox regression analysis to identify nine m6A-associated lncRNAs with prognostic value. The patients with BLCA were divided into two subgroups by consistency clustering. Analysis of the two groups of immune cell infiltration, immune microenvironment and clinical results were significantly different. We identified the prognostic significance of m6A-related lncRNAs by bioinformatic and statistical analysis of data from patients with BLCA.Results: We constructed an m6A-related lncRNA prognostic signature (m6A-LPS, including AL136295.2, AC104564.3, ATP1B3-AS1, EHMT2-AS1 and AC116914.2) to predict the OS of BLCA patients. It is proved that m6A LPS has independent prognostic value.
