Comprehensive Analysis of MicroRNA and mRNA Expression in Normal and Tumorous Human Esophageal Squamous Cell Lines Using Microarray Datasets

Abstract

Despite the undisputed importance of altered microRNA (miRNA) expression in various cancers, there is limited information on the clinicopathologic significance of cancer‐related miRNAs in esophageal squamous cell carcinoma (ESCC). Previously, it was reported that the expression of several miRNAs was dysregulated in ESCC. However, the target genes of these miRNAs have not been identified. Furthermore, additional miRNAs in humans have been discovered recently, indicating that revised miRNA and gene expression profiling for ESCC are necessary. Here, we provide datasets from microarray analyses to identify miRNA and mRNA expression comprehensively in Het‐1A, a normal human esophageal squamous cell line, and three human ESCC cell lines.
