20080200566 | Dephosphorylation of HDAC7 By Myosin Phosphatase - The present invention relates to screening methods that make use of a histone deacetylase interacting with a myosin phosphatase for the identification of novel therapeutics useful for inhibiting or inducing apoptosis and for the treatment of pathological conditions, such as smooth muscle cell disorder, cardiac hypertrophy or asthma. Also disclosed are methods for inhibiting or inducing apoptosis and for treatment of a pathological condition by administering to a mammal a therapeutically effective amount of a compound that inhibits or increases the dephosphorylation of a histone deacetylase by a myosin phosphatase or inhibits or increases the binding of a histone deacetylase to a myosin phosphatase. | 08-21-2008 |

Also provided are histone deacetylase polypeptide compositions. The histone deacteylase nucleic acid molecules are useful in a variety of diagnostic and therapeutic applications, which are also provided. | 09-25-2008 |
20090061015 | Regulation of Protein Activity By Reversible Acetylation - This invention discloses the first cellular acetylated substrate protein of SIRT3, Acetyl-CoA synthetase 2 (AceCS2), which is a mitochondrial matrix protein. AceCS2 is reversibly acetylated at lysine 642 (Lys642) in the active site of the enzyme. The mitochondrial sirtuin SIRT3 interacts with AceCS2 and deacetylates Lys642 both in vitro and in vivo. Deacetylation of AceCS2 by SIRT3 activates the acetyl-CoA synthetase activity of AceCS2. Thus, a mammalian sirtuin directly controls the activity of a metabolic enzyme via reversible lysine acetylation. Modulators of the acetylation status or the activity of AceCS2 are useful for the treatment of pathological conditions, such as type II diabetes, hypercholesterolemia, hyperlipidemia, and obesity. | 03-05-2009 |
20090306131 | CELL LINES WITH LATENT IMMUNODEFICIENCY VIRUS AND METHODS OF USE THEREOF - The present invention provides isolated cells that comprise, integrated into the genome of the cell, a transcription-competent immunodeficiency virus or a transcription-competent immunodeficiency virus-based retroviral vector. Under basal in vitro culture conditions, the immunodeficiency virus is latent, and the expression of the latent immunodeficiency virus can be reactivated. The invention farther provides methods of making a subject cell. The invention further provides screening methods for identifying agents that activate a latent immunodeficiency virus; and screening method for identifying agents that block reactivation of latent immunodeficiency virus expression in response to T cell activation signals. The invention further provides agents identified in the subject screening assays. The invention further provides methods of treating an immunodeficiency virus infection. | 12-10-2009 |
