ChIP assays of CTGF, CYR61 and α-SMA promoters using anti-FLAG-tag, anti-Myc-tag, anti-TEAD1 antibodies in human VSMCs transfected with plasmids expressing Myc-tagged YAP-5SA and/or FLAG-tagged HOXA4. *P<0.05, **P<0.01 vs FLAG-GFP, by unpaired two-tailed Student's t-test. Data are expressed as the means ± SEM of three independent experiments.
