Research firm touts Newfoundland and Labrador seaweed as cancer inhibitor
ST. JOHN’S, N.L. — A cancer researcher says he’s cautiously optimistic about an East Coast ocean technology company’s apparent discovery of properties in seaweed off Newfoundland and Labrador that inhibit the growth of breast cancer cells, but warns the company still faces many hurdles.
Oceans Ltd. announced Wednesday it has been studying the seaweed’s potential commercialization in pharmaceutical products for seven years, and has sampled about 70 seaweed species in Newfoundland and Labrador’s coastal waters.
It said studies that used an extract from the seaweed on mice have “conclusively” demonstrated effectiveness in inhibiting the growth of breast cancer cells.
Dr. David Hoskin, a professor of pathology at Dalhousie University who was not involved with the company or its research, said the product appears promising, but added there have been many natural products that have inhibited growth of human cancer in mice.
