Abstract: 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.

Abstract: 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.

It is based, at least in part, on the characterization of the complete cDNAs encoding rat and human PSGen 13, and on the discovery that increased levels of PSGen 13 expression can suppress the transformed phenotype and inhibit the activities of promoter elements associated with cancer progression and angiogenesis. In various embodiments, the present invention provides a method for inhibiting growth of a cancer cell which comprises contacting the cancer cell with a nucleic acid encoding a PSGen 13 protein, a PSGen 13 protein or a PSGen 13 activator compound in a sufficient amount so as to inhibit growth of the cancer cell.

Abstract: A method and apparatus for managing defect areas of a rewritable optical recording medium. Upon receiving a write or read command from a host, the defect areas management apparatus decodes a PID of a position being currently traced by an optical pickup, generates the resultant physical sector number of the current position and compares it with a physical sector number of a defect area stored in a DMA storage unit. If the two physical sector numbers are the same, the defect areas management apparatus does not write or read data on a sector of the position traced by the optical pickup. Therefore, the defect areas management apparatus is capable of efficiently managing defect areas of the optical recording medium.
