ability of heparin to inhibit HAT is dependent upon its size and structure: small heparin-derived oligosaccharides (above 8 sugars) and N-desulfated or O-desulfated heparin show reduced inhibitory activity. Heparin is shown to bind to pCAF. Enzyme assays indicate that heparin shows the characteristics of a competitive-like inhibitor causing a 50fold increase in the Km of pCAF for histone H4

E2F1
the transcription factor associates with and recruits GCN5 to sites of DNA damage. E2F1 is required for the GCN5-mediated regulation of lung cancer cell growth and for theG1/S transition. Cyclin D1 and cyclin E1 are downstream targets of E2F1. GCN5 is enriched at the E2F1-binding site of the cyclin D1, cyclin E1, or E2F1 promoters
-
laminar shear stress
-
laminar shear stress stimulates acetylation of histones 3 and 4 at the region of the eNOS promoter SSRE and extends 3' toward the eNOS coding region. Laminar shear stress induces p300 binding to p65 and leads to increase of p300 histone acetyltransferase activity by 2.5fold and to increase of acetylation of p65, but not of p50 acetylation, overview
