Histone deacetylation inhibition in pulmonary hypertension: therapeutic potential of valproic acid and suberoylanilide hydroxamic acid.

BACKGROUND Epigenetic programming, dynamically regulated by histone acetylation, is a key mechanism regulating cell proliferation and survival. Little is known about the contribution of histone deacetylase (HDAC) activity to the development of pulmonary arterial hypertension, a condition characterized by profound structural remodeling of pulmonary arteries and arterioles. METHODS AND RESULTS ...

The histone deacetylase inhibitors suberoylanilide hydroxamic (Vorinostat) and valproic acid induce irreversible and MDR1-independent resistance in human colon cancer cells.

Histone deacetylase (HDAC) inhibitors such as suberoylanilide hydroxamic acid (SAHA, Vorinostat), valproic acid (VPA), and FK228 are members of a relatively novel class of small molecular weight chemicals that have high antineoplastic activity. They cause growth inhibition and apoptosis specifically in tumor cells, and they act also as chemo- and radio-sensitizers. In the present study, the pot...

P-117: Gene Expression and Developmental State of Mouse Cloned Embryos after Treatment with Histone Deacetylase Inhibitor,Suberoylanilide Hydroxamic Acid (SAHA)

Background: It is known that acetylation level of the nuclear histones in cloned embryos is lower compare to normally developed embryos. Histone deacetylas inhibitors (HDACi) with improvement of acetylation level in these embryos can affect embryo quality in pre-implantation stage and expression level of different genes especially developmental genes. Materials and Methods: In this research, SA...

Quantitative Analysis of Global Proteome and Lysine Acetylome Reveal the Differential Impacts of VPA and SAHA on HL60 Cells

Valproic acid (VPA) and suberoylanilide hydroxamic acid (SAHA) are both HDAC inhibitors (HDACi). Previous studies indicated that both inhibitors show therapeutic effects on acute myeloid leukaemia (AML), while the differential impacts of the two different HDACi on AML treatment still remains elusive. In this study, using 3-plex SILAC based quantitative proteomics technique, anti-acetyllysine an...
