  • Publication number: 20220370478
    Abstract: The present invention relates to a composition for enhancing a survival rate of stem cells, including an immunosuppressant, and to a use thereof. According to the present invention, a survival rate of stem cells can be remarkably enhanced using a composition including an immunosuppressant, and a therapeutic effect of stem cells can be improved on the basis of the enhancement. The composition can overcome an immune response caused by the administration of xenogeneic cells so as to accurately verify the stability and efficacy of cells, and thus will be able to be utilized as a mesenchymal stem cell therapeutic agent that maximizes a therapeutic effect of stem cells.

  • Publication number: 20130330358
    Abstract: Two vIRF4 (Kaposi's-sarcoma-associated-herpesvirus vIRF4) peptides, vif1, corresponding to aa202-216 of vIRF4, and vif2, corresponding to aa220-236 of vIRF4, are potent and selective HAUSP antagonists. The vif1 and vif2 peptides robustly suppress HAUSP DUB enzymatic activity, ultimately leading to p53-mediated anti-cancer activity. The vif1 and vif2 peptides, along with their homologues, are useful in treating cancer through regulation of p53 activity in a cancer cell. Also disclosed is the crystalline structure of vIRF4-HAUSP TRAF domain complex. The structure is useful in computer aided drug design for identifying an agent that interacts with and inhibits HAUSP, resulting in p53 medicated cell cycle arrest of cancer cells.

  • Patent number: 7667411
    Abstract: A backlight assembly includes a switching section for switching on/off an input voltage so as to output a primary voltage in accordance with a control signal; and a voltage boosting section for boosting the primary voltage received at a primary side thereof to a secondary voltage at a secondary side thereof. The primary and secondary sides of the voltage boosting section are electrically isolated from each other. In a feedback link for supplying the control signal from the secondary side to the primary side, a signal isolation section is provided for both transmitting the control signal between and electrically isolating primary side and secondary side portions of the feedback link. Additionally or alternatively, a balancing circuit section is connected between the secondary side of the voltage boosting section and a plurality of lamps so as to uniformly supply an alternating current, generated by the secondary voltage, to the lamps, in order to uniformize the luminances of the lamps.
