  • Publication number: 20080269158
    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.
