Comprehensive analysis of transcriptome-wide m6A methylome in intermediate-stage Esophageal squamous cell carcinoma

N6-Methyladenosine (m6A) RNA methylation is the most prevalent post-transcriptional modification mechanism in humans and plays an important role in the pathogenesis of various tumors. However, the investigation of m6A modification in Esophageal squamous cell carcinoma (ESCC) remains in its infancy. Transcriptome-wide m6A changes were profiled using human m6A epitranscriptomic microarrays in ESCC tissues and adjacent normal tissues. Differentially m6A-methylated mRNAs, lncRNAs and Mid-size ncRNAs were identified, followed by functional enrichment analysis. Moreover, we also establish a competing endogenous RNA (ceRNA) network based on the m6A-related lncRNA growth arrest specific 5 (GAS5) specific transcript（NR_152533）. The results suggested that RALYL may be a target gene for miR-3912-5p, and that GAS5 regulated RALYL expression by binding to miR-3912-5p.
