  • Patent number: 8883753
    Abstract: Methods and compositions for generating novel nucleic acid molecules through targeted spliceosome mediated RNA trans-splicing that result in expression of a apoAI protein, an apoAI variant, the preferred embodiment referred to herein as the apoAI Milano variant, a pre-pro-apoAI or an analog of apoAI. The methods and compositions include pre-trans-splicing molecules (PTMs) designed to interact with a target precursor messenger RNA molecule (target pre-mRNA) and mediate a trans-splicing reaction resulting in the generation of a novel chimeric RNA molecule (chimeric RNA) capable of encoding apoAI, the apoAI Milano variant, or an analog of apoAI. The expression of this apoAI protein results in protection against vascular disorders resulting from plaque build up, i.e., atherosclerosis, strokes and heart attacks.

  • Patent number: 8852930
    Abstract: Disclosed is a FAST (Flexible Accelerated STOP TetO-knockin) system, an efficient method for manipulating gene expression in vivo to rapidly screen animal models of disease. This invention further discloses a single gene targeting event yielding 2 distinct knockin mice—STOP-tetO and tetO knockin—which permit generation of multiple strains with variable expression patterns: 1) knockout, 2) Cre-mediated rescue; 3) tTA-mediated misexpression; 4) tTA-mediated overexpression; and 5) tTS-mediated conditional knockout/knockdown. Using the FAST system, multiple gain- and loss-of-function strains can therefore be generated on a timescale not previously achievable. These strains can then be screened for clinically-relevant abnormalities. The flexibility and broad applicability of the FAST system is demonstrated by targeting several genes encoding proteins implicated in neuropsychiatric disorders: Mlc1, Neuroligin 3, the serotonin 1A receptor, and the serotonin 1B receptor.

  • Patent number: 8829004
    Abstract: The present invention refers to a method for inducing tumor apoptosis by influencing the ROS (reactive oxygen species) signaling pathway in tumor cells. Increasing the level of ROS leads to the selective inactivation of a tumor cell catalase and subsequently to an apoptosis of these cells. The level of ROS can be increased by increasing the level of nitric oxide through inhibition of the enzymes nitric oxide dioxygenase or arginase. According to the present invention inhibitors of the nitric oxide dioxygenase or arginase can be used for the manufacture of a medicament for the treatment of cancer. The present invention further provides a method for identifying compounds which can be used for the treatment of cancer, wherein the method allows to specifically identify compounds which induce apoptosis through the ROS signaling pathway. The present invention also provides a kit for identifying compounds which induce tumor apoptosis by inactivating a catalase on the tumor cell surface.

  • Patent number: 8802439
    Abstract: The present invention provides methods for producing retroviruses or viral vectors with enhanced infectivity. The methods entail transfecting a retroviral vector into a packaging cell that has suppressed expression or inhibited enzymatic activity of a parvulin prolyl peptidyl isomerase (parvulin PPIase), and culturing the transfected packaging cell to allow production of viral particles. The invention also provides methods for enhancing efficiency of gene transfer with a recombinant retrovirus. These methods involve constructing a recombinant retroviral vector expressing a target gene, transfecting into a packaging cell that has suppressed expression or inhibited enzymatic activity of a parvulin prolyl peptidyl isomerase (parvulin PPIase), culturing the transfected packaging cell to allow production of recombinant retroviral particles, harvesting recombinant retroviral particles from supernatant of the cultured cell, and transducing the recombinant retroviral particles into a target cell.

  • Patent number: 8802361
    Abstract: The present invention provides a perfusion solution comprising specific metabolic agents, antioxidant agents, and membrane stabilizer agents that can help improve preservation, organ viability, and in some cases recover organs that would otherwise being unusable for transplantation. In a further embodiment, the perfusion solution can be used in combination with hypothermic machine perfusion. It has been found that combination of the perfusion solution and hypothermic machine perfusion can help prevent or reduce further damage to the organ and restore the organ's anti-oxidant system, stabilize the cellular cytoskeleton and cellular membranes, inhibit arachidonic acid pathway, provide oncotic support, reduce interstitial edema formation, and help restore energy stores within the organ. As a result, the method can be used to improve the viability of otherwise marginal donor organs.
