article imageCow's milk extract kills cancerous cells

By Tim Sandle     Dec 1, 2013 in Science
A peptide fragment derived from cow's milk has exhibited potent anticancer capability against human stomach cancer cell cultures. The research was undertaken at the University of Taiwan.
The identified fragment from the milk of cows has been described as lactoferricin B25 (LFcinB25). LFcinB25 could be a potential therapeutic agent for gastric cancer. In studies, LFcinB25 reduced the survival of human AGS (Gastric Adenocarcinoma) cells.
Through laboratory tests, a research team showed that after an hour of exposure to the gastric cancer cells, LFcinB25 migrated to the cell membrane, and within 24 hours the cancer cells had shrunken in size and lost their ability to adhere to surfaces.
Gastric cancer is a common form of cancer. The main ways to treat gastric cancer are surgery and chemotherapy, which are generally only successful if the cancer is diagnosed at an early stage. The newly identified milk fragment could pave the way for novel therapies.
It should be noted that the studies so far have been in "test tubes" and the results in people may not necessarily be the same. This will be a subject of further study.
The findings have been published in the Journal of Dairy Science. The paper is titled "Bovine lactoferricin B induces apoptosis of human gastric cancer cell line AGS by inhibition of autophagy at a late stage."
