Profiling the m6A-regulated RNA expression patterns and alternative splicing features in esophageal carcinoma
The m6A modification involves almost all aspects of RNA biology, including the alternative splicing of mRNA precursors, mRNA transport and stability, and miRNA processing and regulation of target genes. Alternative splicing controlling the information storage and RNA translation involves the regulation of various biological processes. Here, we integrated the genomic information of 161 esophageal cancer (EC) samples to comprehensively evaluate the m6A modification patterns and correlated the m6A modification pattern with the prognosis of EC patients, where two distinct m6A modification patterns were proposed. The combined effects of high m6Ascore and low TMB correlated with a better prognosis of EC patients. In addition, we found an inherent correlation between m6A modification and the occurrence of alternative splicing events in EC patients. Altogether, we established a scoring system to quantify the m6A modification pattern with RNA alternative splicing events in individual EC patients.
