Triple negative breast cancer (TNBC) is one of the rarest and most aggressive forms of breast cancer, and there are currently no targeted treatments for it. Chemotherapy is the only option, which comes with many unpleasant side effects.
Dr Lisa Pilkington, a senior research fellow at the University of Auckland, is the recipient of our 2020 Ronald Kay Science Fellowship. She has discovered an enzyme – PC-PLC – that promotes the growth of TNBC, as well as a drug that can act as a PC-PLC blocker to prevent TNBC cells from growing. The trouble is, the blocker degrades within seconds, so it never reaches its target. This new research focusses on altering the structure of the blocker so that it can survive in the body long enough to kill TNBC cells. You could say the PC-PLC enzyme is a lock, now work is being done to find the key to unlock an effective treatment for TNBC.
