Publication number: 20090203885Abstract: The present invention relates to Astrocyte Modulated Genes (AMGs). AMGs are genes whose expression are modulated in human astrocytes grown in primary cell culture following the exposure of these cells to either the human immunodeficiency virus HIV-1 or to the HIV-1 protein gp120. AMGs comprise both Astrocyte Enhanced Genes (AEGs) and Astrocyte Suppressed Genes (ASGs). Thus, the present invention further relates to Astrocyte Enhanced Genes (AEGs), the expression of which are up-regulated in human astrocytes grown in primary cell culture that are exposed to either the human immunodeficiency virus HIV-1 or to the HIV-1 protein gp120, and to Astrocyte Suppressed Genes (ASGs), the expression of which are downregulated in human astrocytes grown in primary cell culture that are exposed to either the human immunodeficiency virus HIV-1 or to the HIV-1 protein gp120. Because they may play a role in HIV-associated dementia (“HAD”), AMGs may be used as markers in methods for screening for drugs that treat or prevent HAD.Type: ApplicationFiled: April 13, 2009Publication date: August 13, 2009Inventors: Paul B.

Publication number: 20050186211Abstract: The present invention relates to mda-5 nucleic acids, MDA-5 proteins, the mda-5 promoter, and related molecules, and the use of each of these elements in protecting against or limiting viral infection, controlling cell proliferation, and promoting apoptosis. It is based upon the discovery that, contrary to earlier hypotheses based on the amino acid sequence of MDA-5, the protein is not a defective ATPase but rather exhibits ATPase activity. This supports the role of MDA-5 as a RNA helicase protein and consequently its use in promoting RNA degradation, for example in the context of antiviral defense, limitation of cell proliferation, or induction of apoptosis.Type: ApplicationFiled: January 24, 2005Publication date: August 25, 2005Inventors: Paul Fisher, Dong-Chul Kang, Rahul Gopalkrishnan
