ITGA5 and neoplasm: We matched the expression profiles of three prognostic genes in the TCGA-BLCA (Supplementary Figure 1A) and GSE7476 (Supplementary Figure 1B) datasets and found that both ITGA5 and ITGA7 were significantly reduced in tumor samples; while ITGB6 was notably overexpressed in the BLCA group (all P< 0.05).
