Genome-wide identification of transcriptional targets for H3K23ac, H3K27ac, and H4K5ac in vascular smooth muscle cells of aneurysmal aortas [CUT&Tag]

In this study, we found that H3K23ac, H3K27ac, and H4K5ac level are elevated in VSMCs of aneurysmal aortas. To further explore the potential functional significance of H3K23ac, H3K27ac, and H4K5ac in aortic aneurysm, we performed genome-wide cleavage under targets and tagmentation (CUT&Tag) analysis to identify candidate genes regulated by H3K23ac, H3K27ac, or H4K5ac in rat VSMC. Following CUT&Tag, H3K23ac, H3K27ac, or H4K5ac-associated DNAs were amplified using non-biased conditions, labeled, and sequenced with Illumina NovaSeq 150PE.
