VEGFA isoforms and +157 enhancer region. (A) Schematic representation of the VEGFA gene and four of its known isoforms. Rectangles: exons, black lines: introns. Arrows in black indicate primers for isoform VEGFA121 and arrows in red for VEGFA189. (B) ChIP-seq tracks for H3K27ac and H3K4me1 including DHS and Hi-C data (5 kb resolution) at the VEGFA locus in K562 cells. VEGFA +157 enhancer is depicted with a black arrow and enriched for H3K27ac and H3K4me1. The Hi-C data suggest a sub-TAD between VEGFA +157 enhancer and the promoter, marked with a black box. Green arrows depict additional enhancers with sub-TADs to VEGFA promoter.
