Takashi Sugimura (杉村 隆, Sugimura Takashi, April 20, 1926 – September 6, 2020) was a Japanese biochemist, famous for research on chemical carcinogens. He received the Japan Prize for the contribution to establishment of fundamental concept on causes of cancer.[1] He was elected as President of the Japan Academy on October 15, 2013,[2] serving till 2016 and was followed by Hiroshi Shiono.[3]
Contribution
Sugimura isolated and identified many mutagens with a structure of heterocyclic amine from foods cooked under ordinary conditions. He showed that tumors induced by these heterocyclic amines had genetic alterations. He further developed his studies to analyze multiple-step carcinogenesis at molecular levels to promote effective primary prevention of cancer.[4] His group identified the novel polymer poly(ADP-ribose) and demonstrated the presence of the enzyme poly ADP ribose polymerase (PARP). He also discovered the cognate catabolic enzyme, poly(ADP-ribose) glycohydrolase (PARG) and further elucidated the biology of poly(ADP-ribose). The discovery of pierisin, an apoptogenic peptide that ADP-ribosylates DNA, profoundly illuminates his scientific character and curiosity as well.[5]
