  • Publication number: 20190358277
    Abstract: The present invention relates to an anticancer composition comprising a recombinant adenovirus which expresses degradation factors for the extracellular matrix. The recombinant adenovirus according to the present invention exhibits an excellent anti-tumor effect by remarkably reducing the main structural components of the extracellular matrix in a tumor tissue, including collagen I, collagen III, fibronectin, elastin, and the like and highly expressing a therapeutic gene selectively only in tumor cells through viral proliferation. Particularly, when administered in combination with therapeutic materials, such as anticancer agents or immune checkpoint inhibitors, the recombinant adenovirus significantly increases the diffusion and distribution of the co-administered therapeutic materials in tumor tissues while allowing the exertion of the preexisting anticancer effects, thereby further improving an anti-cancer effect.

  • Publication number: 20180369417
    Abstract: The present invention relates to an oncolytic adenovirus simultaneously expressing interleukin-12 and shVEGF, and an antitumor immunity enhancing composition and an anticancer effect promoting composition each containing the same. The present inventors verified that the simultaneous occurrence of VEGF inhibition and IL-12 expression induced the recovery of an immune function and the promotion of an anticancer effect in an immunological mouse melanoma or kidney cancer model. Especially, the applicability of a gene carrier simultaneously expressing IL-2 and shVEGF in the cancer gene therapy was first established by disclosing that the increased anticancer effect is involved in an increase in anticancer immunity, an increase in TH 1 cytokine, and the prevention of tumor induced thymic atrophy.

  • Publication number: 20180326094
    Abstract: The present invention relates to a pharmaceutical composition for preventing or treating a keloid disease or scars. The inventors of the present invention discovered that mortalin expression inhibition and the interaction between mortalin and p53 may be new targets for keloid treatment. In the present invention, apoptosis and an anti-fibrotic effect were verified by preparing a mortalin-specific shRNA (dE1-RGD/GFP/shMOT) and injecting same in a keloid spheroid. Thus, by reducing ECM expression and inducing apoptosis in a keloid spheroid, mortalin knockdown may be very usefully employed for keloid treatment.
