Biological Activity for Sodium 4-Phenylbutyrate

Sodium 4-Phenylbutyrate is a histone deacetylase inhibitor that displays anticancer activity. Inhibits cell proliferation, invasion and migration and induces apoptosis in glioma cells. Sodium 4-Phenylbutyrate also inhibits protein isoprenylation, depletes plasma glutamine, increases production of fetal hemoglobin through transcriptional activation of the γ-globin gene and affects hPPARγ activation.

Rheumatoid Arthritis Poster

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.
