  • Patent number: 9066976
    Abstract: The present invention relates to the E2EPF UCP-VHL interaction and the uses thereof, more precisely a method for increasing or reducing VHL activity or level by regulating UCP activity or level to inhibit cancer cell proliferation or metastasis or to increase angiogenesis. The inhibition of UCP activity is accomplished by any UCP activity inhibitor selected from a group consisting of a small interfering RNA (RNAi), an antisense oligonucleotide, and a polynucleotide complementarily binding to mRNA of UCP, a peptide, a peptide mimetics and an antibody, and a low molecular compound. In the meantime, the increase of angiogenesis is accomplished by the following mechanism; UCP over-expression is induced by a gene carrier and thus endogenous VHL is reduced, leading to the stabilization of HIF-1? which enhances VEGF activation based on the HIF-1? stabilization.

  • Patent number: 8404435
    Abstract: The present invention relates to Enigma (PDLIM7)-Mdm2 interaction and use thereof. More particularly, it may induce an effective apoptosis of cancer cells by inhibition of an Enigma expression or an Enigma activity which induces Mdm2 destabilization and p53 activity; it may assess the prognosis of anti-cancer therapy by determining that Enigma, which is induced by SRF, is overexpressed in cancer tissues with Mdm2; it may screen anti-cancer activity substances by selecting a factor to inhibit specific binding between Enigma and Mdm2. Enigma-Mdm2 interaction and Enigma expression regulation may be utilized usefully for preventing cancers and developing therapeutic methods and anti-cancer agents.
