Dr. Zhang Shiqing, a former PhD student of DST, won the 2019 Asia Young Scientist Award.  He will receive the award in the annual meeting of the Japanese Cancer Society to be held in September 26-28, 2019 in Kyoto. Each year two cancer researchers from Asia (excluding the two awards specifically for Japanese Researchers) under the age of 35 are given the award. Selection of the awardees is organized by the Journal Cancer Science.

Dr Zhang received the Cancer Science Young Scientists Award in Japan on Sep 28, 2019

Dr. Zhang’s award is based on his thesis research carried out under the supervision of Prof. Stephen Chung. He identified a novel anti-cancer mechanism that target certain types of cancer cells. Most current anti-cancer drugs are not specific for killing cancer cells. They preferentially kill cancer cells because they kill fast growing cells and cancer cells usually grow faster than normal cells. Unfortunately many normal cells also grow fast and they are also killed by these drugs. As a result, chemotherapy is usually accompanied by undesirable side effects.

Dr. Zhang identified a new class of anti-cancer drugs whose toxic effects are activated by two enzymes (AKR1B1 and AKR1B10) that are more abundant in some cancer cells, providing specificity in treating these cancers. He showed that good substrates of these enzymes can specifically kill cancer cells that have higher levels of these enzymes. These drugs were shown to be effective in retarding tumor growth in mice. These drugs should be effective in treating liver, lung, breast, and pancreatic cancers which usually have high levels of AKR1B1 and AKR1B10 (see reference for details). Applications for patent protection of this invention had been submitted in China and USA.
