The bioinformatics analysis was carried out to state that the CXCL9 expression was remarkably upregulated in UCEC tumor, compared with control ones based on the TCGA+GTEx dataset (P< 0.0001, Figure 1A), TCGA dataset (Figure 1B, P=0.0003), GSE36389 (Figure 1C, P=0.014) and tissues of our validation cohort (Figure 1D, P= 0.011). The gene discussed is CXCL9; the disease is neoplasm.
