Tool Details
- Tool name: Histone deacetylase 3 (HDAC 3) knockout mouse embryonic stem cell line
- Tool type: Cell Lines
- Conditional: Yes
- Conditional description: Induction of Cre activity by addition of 4-hydroxy tamoxifen (OHT) to the growth media resulted in complete recombination of each allele and deletion of exon 2 (HDAC1ÄÂ?Â2/ÄÂ?Â2 or HDAC2 ÄÂ?Â2/ÄÂ?Â2) within 24 h
- Description: Responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. Histone deacetylases act via the formation of large multiprotein complexes. Histone deacetylase 3 (HDAC3) acts as the catalytic core of the SMRT/NCoR co-repressor complex which regulates chromatin structure and gene expression. It was recently shown that HDAC3 binds, and is regulated in vitro, by the binding of inositol phosphates (IP).
- Research area: Developmental biology
- Production details: E14 ES cells, expressing a CreER fusion protein from the ROSA26 locus, were used to generate HDAC3Lox/Lox; CreER cell lines by consecutive rounds of gene targeting.

Target Details
- Target: Histone deacetylase 3
Application Details
- Application notes: Loss of exon 3 via the conditional KO disrupts the ORF of HDAC3 such that a premature stop codon is introduced. Following this deletion of exon 3 a further 4?Â5 days of culture are required before HDAC3 protein levels are reduced below 10% of those of control cells. "Loss of HDAC3 does not cause a significant reduction in total deacetylase activity with only minor changes in the acetylation levels of histones. However, the proliferative capacity of knockout cells is inhibited with a delay in cell doubling time. Upon differentiation, embryoid bodies (EBs) lacking HDAC3 are significantly smaller and morphologically different compared to controls. Microarray analysis over a 7-day time course of EB differentiation reveals that endodermal cell markers are over-expressed at both early and late stages of development, suggesting that HDAC3 plays an important role in regulating gene expression during embryonic development."
