Esophageal squamous cell carcinoma (ESCC) is the dominant subtype of esophageal cancer worldwide. This study aimed to explore the aberrant global expression profiling and construct regulatory network in ESCC for understanding tumorigenesis of ESCC. The expression pattern of long non-coding RNA (lncRNA), microRNA (miRNA) and mRNA was measured by RNA-sequencing in ESCC. Differentially expressed lncRNAs/miRNAs/mRNAs (DELs/DEMs/DEMIs) were identified in ESCC. DEMIs-DEMs network was constructed; hsa-miR-424-5p and hsa-miR-450b-5p were the hub miRNAs in the network, which negatively regulated 19 and 17 DEMs. DEMs targeted by DEMIs were significantly enriched in MAPK signaling pathway, pathways in cancer and focal adhesion signaling pathway. The expression of candidate DEMs and DEMIs in ESCC were validated through quantitative real-time polymerase chain reaction and microarray expression profiling analyses, and the results were generally consistent with our bioinformatics analysis. Our results might provide useful information for exploring the tumorigenesis mechanism and potentially therapeutic targets in ESCC.
