To provide further support for the notion that both CCNE1 and CCNE2 can be the direct target genes of YAP1-TEAD4 complex in BLCA cells, we used T24 and Sw780 cells to perform the luciferase reporter assay for the promoter regions of CCNE1 and CCNE2 genes. The gene discussed is CCNE1; the disease is bladder transitional cell carcinoma.
