Figure Lengend Snippet: MNX1 directly upregulates CCNE1 and CCNE2 promoter activity in bladder cancer cells. a Real-time PCR of cell cycle–related gene mRNA expression. Gene expression levels were normalized to GAPDH . Pseudo-colors represent the intensity scale of MNX1 versus vector or MNX1 shRNA#1/2 versus Scramble, generated by log2 transformation. b Western blotting of CCNE1, CCNE2, phosphorylated Rb (p-Rb), and total Rb protein expression; α-tubulin was used as the loading control. c The scatter diagram of CCNE1 and CCNE2 from cBioportal program. d and e Left: Luciferase activity assays of T24 and 5637 cells showed transactivation and repression of the CCNE1 ( d ) and CCNE2 ( e ) promoters by MNX1 overexpression and MNX1 knockdown, respectively. Right: Schematic illustration of ChIP PCR fragments for the indicated nucleotide regions of the CCNE1 ( d ) and CCNE2 ( e ) promoters (top). The ChIP enrichment assay confirmed that MNX1 binds to the P4 and P5 promoter of CCNE1 ( d ) and the P6 and P7 promoters of CCNE2 ( e ); immunoglobulin G (IgG) was used as the negative control. The results from three independent experiments were evaluated. * p < 0.05; ** p < 0.01. shRNA, short hairpin RNA
