JUN recruits p300, promotes H3K27ac histone modification, and increases chromatin accessibility and TCF21 binding. a–f ChIP-qPCR at SMAD3-1, SMAD3-2, and CDKN2BAS locus regions with input normalization in HCASMC. a JUN binding was evaluated under conditions of JUN (JUN-KD) and scrambled (Ctrl) siRNA transfections. b Validation of overexpressed TCF21 mRNA level under conditions of JUN-KD and Ctrl siRNA transfections by RT-qPCR. c pWI lentivirus expressed TCF21 binding was evaluated under conditions of JUN-KD or Ctrl siRNA transfection. d H3K27ac level was evaluated under conditions of JUN-KD or Ctrl siRNA transfection. e Chromatin accessibility assessed by ATAC-qPCR was evaluated under conditions of JUN-KD or Ctrl siRNA transfection. f p300 binding at SMAD3-1/SMAD32 and CDKN2BAS loci was evaluated under conditions of JUN-KD or Ctrl siRNA transfection. g Serial ChIP-qPCR with JUN first IP followed by p300 second IP. h Serial ChIP-qPCR with p300 first IP followed by JUN second IP (mean ± SD, n = 3)
