Nobel Laureate Barry J. Marshall Visits China National GeneBank-Shenzhen
Barry J. Marshall, winner of Nobel Prize in Physiology or Medicine, paid a visit to China National GeneBank-Shenzhen (CNGB-Shenzhen) on May 25, delivering a keynote speech titled “Helicobacter Pylori: Theory & Practice.” Professor Marshall presented the research process of his discovery of Helicobacter pylori (HP) and a hypothesis he proposed that both gastric ulcers and gastric carcinomas are caused by this kind of bacteria. Not only was his conclusion on this hypothesis originally not accepted by the medical community, but also the submissions of his related articles to be published were rejected over and over again. To prove his theory, Professor Marshall managed to test the bacteria in his own body following Koch's Postulates, and he together with J. Robin Warren was awarded the Nobel Prize in Physiology or Medicine for their discovery of HP and its effect on diseases such as gastritis and gastric ulcer in 2005. Professor Marshall was received enthusiastically by the audience members who engaged in heated discussion with him on issues like carcinogenic mechanism of the bacteria and the development of vaccines. Following the discussion, Zhu Shida, Vice President of CNGB-Shenzhen, presented Professor Marshall with an appointment letter engaging him as an advisor of CNGB-Shenzhen.
