Biomedical Genomics Research Center
Our goal is to establish world-class genomics-based technology platforms and to apply them to biomedical research programs. This will achieve high-throughput identification and global function analysis of the genes associated with diseases most prevalent in the Korean population, such as colon, stomach and liver cancers. We also conduct functional and chemical genomics research to discover validated targets and biomarkers for the development of effective diagnostics and therapeutics.

  • The anti-apoptotic mechanism of human TIPRL in HCC
    • Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is one of the most promising of the apoptosis-based antitumor agents. However, many cancer cells remain resistant to TRAIL-induced apoptosis, and the resistance mechanism is not clear. We report that human TIP41 is a novel anti-apoptotic target that causes cancer cells to develop resistance to TRAIL. Human TIP41, which is overexpressed in liver and lung cancer cells, interacted with MKK7 and PP2Ac to promote their dephosphorylation. A knockdown of TIP41 combined with TRAIL sustained MKK7/JNK activation and induced apoptotic cell death. These results suggest that human TIP41 may be a useful target for the development of future therapeutic strategies for TRAIL resistance.
  • E2-EPF UCP as a target for therapeutic angiogenesis.
    • E2-EPF ubiquitin carrier protein (UCP) stabilizes hypoxia-inducible factor-1α (HIF-1α) inducing ischemic vascular responses. We investigated the effect of UCP gene transfer on therapeutic angiogenesis. Adenovirus-encoded UCP (Ad-F-UCP) and conditioned media from UCP-overexpressing cells increased the expression of angiogenic factors threby promotes vascularization in cells and mice. In mouse hindlimb ischemia model (N = 30/group), only 23% of the mice injected with Ad-F-UCP showed autoamputation after 21 days of treatment. UCP gene transfer prevented muscle degeneration and autoamputation of ischemic limb. The results suggest that E2-EPF UCP may be a target for therapeutic angiogenesis.
  • Novel epigenetic target in gastric cancer
    • In the current study, we newly found that the promoter of the gene coiled-coil domain-containing 67 (CCDC67) was to be frequently methylated in gastric cancer cell lines and in primary gastric tumors. Treatment with 5-aza-2'-deoxycytidine and/or trichostatin A restored CCDC67 expression in down-regulated cell lines. Pyrosequencing analysis of 150 paired primary gastric cancer samples revealed that promoter CpG methylation was increased in 74% of tested tumors compared with paired adjacent normal tissues, and this hypermethylation correlated significantly with down-regulation of CCDC67. Stable transfection of a CCDC67 gene in gastric cancer cells inhibited adhesion-dependent and -independent colony formation, and CCDC67 expression suppressed tumorigenesis in nude mice, suggesting that CCDC67 is a putative tumor suppressor gene that is silenced in gastric cancers by promoter CpG methylation and that it may play an important role in cell signaling and migration related to tumorigenesis.
  • Function of PRL-3 in cancer metastasis
    • It was found that Phosphatase of regenerating liver (PRL-3) induced MMP-7 through oncogenic pathways including PI3K/AKT and ERK and that there is a relationship between the expression of PRL-3 and MMP-7 in human tumor cell lines. These results suggest that the migration and invasion of PRL-3- expressing CRC cells depends primarily on the expression of MMP-7.
