Acetylated histones are a key component of the epigenetic regulation of gene expression in eukaryotic cells. Histone acetylation involves the addition of an acetyl group to the lysine residues on the histone proteins that make up the nucleosome, which is the basic unit of chromatin. This process is generally associated with transcriptional activation, as it loosens the interaction between the DNA and the histones, allowing the transcription machinery to access the DNA and read the genetic information. Abnormalities in histone acetylation, such as global hypoacetylation or hyperacetylation, can lead to dysregulation of gene expression and have been implicated in various diseases, including cancer. Understanding the role of acetylated histones in gene regulation is crucial for developing therapeutic strategies for these diseases.

ICC analysis of HeLa cells treated with TSA (500ng/ml,4h) (top panel) and HeLa cells untreated with TSA (500ng/ml,4h) (below panel). Anti- Histone H4 (acetyl K5 + K8 + K12 + K16) antibody was used at 1/500 dilution (Green) and incubated overnight at 4°C. Goat polyclonal Antibody to Rabbit IgG - H&L (Alexa Fluor® 488) was used as secondary antibody at 1/1000 dilution. The cells were fixed with 100% ice-cold methanol and permeabilized with 0.1% PBS-Triton X-100. Nuclei were counterstained with DAPI (Blue). Counterstain with tubulin (Red).
Chromatin immunoprecipitation (ChIP) was
performed on HeLa+TSA (500ng/ml,4h) (+) cells
cross - linked with 1% formaldehyde for 10 min,
then chromatin was fragmented by sonication.
Parallel reactions used Histone H4 (acetyl K5 +
K8 + K12 + K16) Recombinant Rabbit mAb (S-902-37)
and Rabbit mAb IgG Isotype Control (SDT-R173)
at 1:50 for immunoprecipitation.
Post - immunoprecipitation, both samples
were washed, eluted, and cross - links
reversed. Purified DNA was analyzed by qPCR.

showed the enrichment of RPL30, GAPDH, MYOD1,
AFM, SAT-α and SAT-2 in Histone H4 (acetyl K5 + K8 +
