BACH1 as a master regulator gene in vascular cells during aging
We identify transcription factor BACH1 as a master regulator in vascular cells during aging. BACH1 is upregulated in the aorta of old mice. We find BACH1 is located on open chromatin and BACH1 binds to CDKN1A gene enhancer and activates its transcription in endothelial cells. Finally, BACH1 aggravates endothelial cell senescence under oxidative stress. Thus, these findings demonstrate a crucial regulatory role of BACH1 in vascular aging. Overall design: HUVEC cells were treated with consiRNA or Bach1 siRNA
