Biological Activity for Trichostatin A

Trichostatin A is a selective and potent inhibitor of class I and II histone deacetylases (HDAC) (Ki = 3.4 nM, IC50 values are 4.99 nM, 5.21 nM, 16.4 nM, 24.3 nM, 27.6 nM for HDAC1, 3, 6, 10 and 4, respectively). Trichostatin A induces accelerated dedifferentiation of primordial germ cells (PGCs) into embryonic germ (EG) cells. Trichostatin A potently inhibits a range of breast cancer and melanoma cell lines (IC50 = 29-400 nM) and induces apoptosis in prostate cancer cells. In an animal model of Huntington's disease, inhibition of HDAC by Trichostatin A rescues memory deficits and increases expression of CREB/CBP target genes in mutant mice. Activates autophagy, increases vesicular transport of BDNF (Cat. No. 2837) and is active in vivo.Trichostatin A enhances CRISPR-Cas9 gene editing of human induced pluripotent stem cells (iPSCs).

Rheumatoid Arthritis Poster

Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
