We then downloaded the RNA-seq analysis results obtained from ESCC samples in the TCGA database and categorized all the data into two phenotype groups, the high-level group and low-level group, according to the median expression level of CXCL10, TNFAIP3, INHBA, and PLAU, respectively. This evidence concerns the gene CXCL10 and esophageal squamous cell carcinoma.
