  • Publication number: 20160108101
    Abstract: Recombinant therapeutic cytokines (“therakines”) for the treatment of cancer are provided. The recombinant therakines include a truncated region of MDA-7/TL-24 (“M4”) not normally found in nature that has anti-cancer activity and a secretory signal which causes secretion of the therakine from plasmid/virus transduced normal and cancer cells and interaction of the therakine to MDA-7/IL-24 receptors on adjacent, neighboring and distant cancer cells. Therakine interaction results in bystander killing of the target cancer cell as well as adjacent, neighboring and distant cancer cells.

  • Publication number: 20120195935
    Abstract: Microbubble-assisted delivery of viruses is disclosed. In particular, methods for targeting a virus to cancer cells in an immunocompetent animal by administering a selectively replicating virus to the immunocompetent animal and disrupting the microbubbles in a location of the animal comprising cancer cells are provided. The virus is encompassed in a suspension of microbubbles, and the surface of the suspension does not include any virus. A suspension of microbubbles comprising a selectively replicating virus that is encompassed in a suspension of microbubbles, which does not include any virus on the surface of the suspension, is also provided.

  • Publication number: 20100189680
    Abstract: This invention provides a method for reversing the cancerous phenotype of a cancer cell by introducing a nucleic acid having the melanoma differentiation associated gene (mda-7) into the cell under conditions that permit the expression of the gene so as to thereby reverse the cancerous phenotype of the cell. This invention also provides a method for reversing the cancerous phenotype of a cancer cell by introducing the gene product of the above-described gene into the cancerous cell so as to thereby reverse the cancerous phenotype of the cell. This invention also provides a pharmaceutical composition having the melanoma differentiation associated gene (mda-7) or the gene product of the melanoma differentiation associated gene (mda-7) effective to reverse the cancerous phenotype of a cancer cell and a pharmaceutically acceptable carrier.

  • Publication number: 20100120153
    Abstract: The present invention relates to MDA-7 variant proteins which are deficient in or lack glycosylation. It is based, at least in part, on the results of experiments which have demonstrated that such variants are functionally equivalent to wild-type MDA-7 protein. Such proteins may be more easily produced large-scale than the wild-type protein, and may be found to be less immunogenic (thereby facilitating treatment, especially repeated treatments). Accordingly, the present invention provides for such proteins (‘Gly(def)MDA-7 proteins’), nucleic acids encoding them (‘Gly(def)mda-7 nucleic acids), pharmaceutical compositions comprising such proteins or nucleic acids, and related methods of treatment.

  • Publication number: 20090203885
    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.
