Anti-cancer potential of natural-source compounds, including cationic antimicrobial peptides and phytochemicals found in common spices; manipulation of T lymphocyte signal transduction for cancer control
Exploring the cancer-fighting potential of food and spice derivatives
Dr. David Hoskin has found that a fragment of milk protein known as lactoferricin triggers the death of cancer cells obtained from a wide range of human malignancies, including breast, colon and ovarian tumours and various leukemias and lymphomas. He is working on methods to deliver lactoferricin and other anti-cancer peptides directly to cancer cells. Dr. Hoskin is also investigating the anti-cancer activity of molecules found in common spices like turmeric and black pepper.
Membership Status:Dr. Hoskin is a BHCRI Senior Scientist, has served on the BHCRI Working Group, BHCRI Development Board, CRTP Management Committee, BHCRI Training Committee and has been a supervisor for CRTP trainees.
