Researchers at the University of Maryland School of Medicine have
identified a peptide, or protein, derived from Pacific cod that may
inhibit prostate cancer and possibly other cancers from spreading,
according to preclinical research published online in the Proceedings of the National Academy of Sciences (PNAS).
"The use of natural dietary products with anti-tumor activity is an important and emerging field of research," says senior author Hafiz Ahmed, PhD, assistant professor of biochemistry and molecular biology at the University of Maryland School of Medicine and scientist at the Institute for Marine and Environmental Technology (IMET). "Understanding how these products work could allow us to develop foods that also act as cancer therapeutics and agents for immunotherapy.
"This study is among the first to explore the therapeutic utility of a bioactive cod TFD-containing glycopeptide to inhibit prostate cancer from progressing," says Dr Ahmed.
The TFD (Thomsen-Friedenreich disaccharide) antigen in the fish protein is hidden in normal human cells but is exposed on the surface of cancer cells and is believed to play a key role in how cancer spreads. Polar fish, such as northern cod, express glycoproteins that are rich in the TFD antigen, which protect them from freezing.

Aquaculture business, Clean Seas Tuna, Australia is moving to raise $3.6 million to drive its Southern Australian yellowtail kingfish operations. The company has struggled, reporting a $34 million first half net loss but hopes for a first-ever profit in 2015.

Scientists in British Columbia, Canada are using the DNA of farmed salmon to help study the prevalence of disease in wild Pacific salmon. More than 90 percent of wild juvenile salmon die before they return to spawn. Although disease is believed to be responsible for excessive mortality, little is known about it as it is rare to see a diseased wild fish.
This is where farmed fish can help. Researchers at a joint project between Genome BC, the PSF and Fisheries and Oceans Canada are collecting tissue samples from salmon (wild and farmed, diseased and healthy) to analyse the genomes of the diseases the fish carry.
