Sodium butyrate has been used:
  • as a component in homogenization and immunoprecipitation buffer for HDAC inhibition in fly embryos and insect s2 cells.
  • as histone deacetylase inhibitor in breast cancer cell line MDA-MB-231, analysed by cell viability assay and viral replication assay.
  • to enhance the production of recombinant tissue-plasminogen activator (t-PA) in Chinese hamster ovary (CHO) cells in a bioreactor.

Biochem/physiol Actions

Sodium butyrate is a short-chain fatty acid that inhibits histone deacetylase (HDAC) in the millimolar range. Decreases Ca2+ release from intracellular stores. Induces apoptosis in several cell lines. Sodium butyrate induces the production of recombinant protein in Chinese hamster ovary (CHO) cells and other human cell lines. Sodium butyrate affects the proteome and gene expression pathways in the cells. It represses cell cycle related genes and modifies the genes involved in cell metabolism and apoptosis.

The majority of mammalian genomes are devoted to transposable elements (TEs). Whilst TEs are increasingly recognized for their important biological functions, they are a potential danger to genomic stability and are carefully regulated by the epigenetic system. However, the full...

Somatic cells can be reprogrammed into induced pluripotent stem cells (iPSC) by the forced expression of the transcription factors OCT4, SOX2, KLF4 and c-MYC. Pluripotent reprogramming appears as a slow and inefficient process because of genetic and epigenetic barriers of...


Naive Pluripotent Stem Cell Culture in an Inhibitor Based 2i/LIF Containing Serum-Free and Feeder-Free Stem Cell Media

Naive pluripotent stem cells are located within the epiblast of mature blastocysts. These primitive “ground-state” cells may be cultured in vitro using specialized media and small molecule inhibitors.

Histone Modification and Chromatin Remodeling | Epigenetics

Epigenetic modifications are thought to occur through two key interconnected processes—DNA methylation and the covalent modification of histones.
