Achievements
  • Finding new cancer gene that controls lactic acid signal
    • Finding out that lactic acid, which used to be known as fatigue material works as an important signal material that controls cell growth and creation of blood vessel
    • Presenting the possibility of developing efficient cancer treatment and treatment for inflammatory disease targeting both metabolic process and signal delivery system of cancer cells by controlling newly found lactic acid signal control gene NDRG3
  • Development of new anti-cancer agents
    • Low molecular compound was made targeting RhoB which is known to deter the growth of cancer cell and applied to the mouse suffered from liver and prostate cancer. It is found that the growth of cancer cell is deterred significantly and the side-effect of losing weight upon injecting existing anti-cancer agent is improved
    • Compared to normal cells, cancer cell is exposed to very severe proteotoxic stress and cancer cell excessively express molecular chaperones through HSF1 activities for their survival and growth (non-oncogene addiction). The low molecular compound targeting‘HSF1’ (KRIBB11, cantharidin, fisetin) were synthesized and separated and injected to mouse suffered from colon cancer. It is found that the growth of cancer cell deterred significantly and weight loss after injecting toxic anti-cancer agent is not found.
    • The anti-cancer effect was demonstrated by animal test and anti-cancer effect is excellent and safe from the perspective of toxicity. Accordingly, intranational competitiveness in new anti-cancer agents development is secured.
  • Identification of target protein and finding mechanism of LW6, a new anti-cancer agent
    • LW6 chemical probe, which has HIF-1 deterring activity was synthesized and molecular target/fluorescent substance/chemical probe compound was made through photoaffinity labeling and click reaction and separated by electrophoresis. Then MDH2 was confirmed to be LW6 molecular target through proteome analysis
    • It is found that if the LW6, a HIF-1 deterrent is combined with Malate Dehydrogenase 2 (MDH2), the respiratory ability of mitochondria and oxygen partial pressure in cell increases promoting the decomposition of HIF-1
