We demonstrate that both the IL-5 mRNA expression and IL-5 protein production were stimulated by TSA and NaBu treatments. Chromatin immunoprecipitation assays showed that treatments of TSA and NaBu caused hyperacetylation of histones H3 and H4 at the IL-5 gene promoter in Jurkat cells, which consequently promoted the exogenous luciferase activity driven by this promoter.
