H3K9ac is an epigenetic modification to the DNA packaging protein Histone H3. It is a mark that indicates the acetylation at the 9th lysine residue of the histone H3 protein. The H3K9 histone has two jobs.

Based on H3K4me3, H3K9ac, H3K27ac, H3K27me3 and H3K9me3 histone tags, respectively, we investigated 25,075 human genes and 3121 molecular pathways.

2024年1月30日 · Here, we profiled the genome-wide landscapes of H3K9ac for paired adjacent normal (Nor), primary ESCC (EC) and metastatic lymph node (LNC) esophageal tissues from three ESCC patients. Compared to...

2017年9月1日 · Two histone marks on histone H3, lysine 4 trimethylation (H3K4me3) and lysine 9 acetylation (H3K9ac), co-localize on active gene promoters and are associated with active transcription. H3K4me3 can promote transcription initiation, yet the functional role of H3K9ac is much less understood.

2018年12月17日 · We conducted an epigenome-wide association study using the histone 3 lysine 9 acetylation (H3K9ac) mark in 669 aged human prefrontal cortices; in contrast with amyloid-β, tau protein burden had...

2024年10月10日 · In this study, we reconstruct high-resolution 3D genome maps based on genomic regions marked by H3K9ac, an active histone modification that dynamically responds to soil water variations in rice.

2017年4月18日 · Here we established a transgenic plant cell line to track histone H3 lysine 9 acetylation (H3K9ac) with a modification-specific intracellular antibody (mintbody). The H3K9ac-specific mintbody...

2012年8月24日 · Genome-wide H3K9ac and H3K14ac show very high correlation between each other as well as with other histone marks (such as H3K4me3) suggesting a coordinated regulation of active histone marks.

2022年1月22日 · In this study, a genome-wide characterization for acetylated lysine 9 on histone H3 (H3K9ac) binding regions in normal temperature (18 °C) and heat-stress conditions (26 °C) via ChIP-seq were carried out. The results that revealed H3K9ac was an extensive epigenetic modulation in A. japonicus.

To study the mitotic regulation of H3K9ac, we used an array of inhibitors targeting specific histone deacetylases. We evaluated the involvement of the targeted enzymes in regulating H3K9ac during all mitotic stages by immunofluorescence and immunoblots. We identified HDAC2, HDAC3, and SIRT1 as modulators of H3K9ac mitotic levels.
