Can Cows Milk Kill Cancer Cells in Culture?

logo1267406_mdA new study published in the Journal of Dairy Science concluded that a peptide fragment derived from cow’s milk, known as actoferricin B25 (LFein25) exhibited potent anticancer capability against human stomach cancer cell cultures.

Investigators evaluated the effects of 3 peptile fragments from lactoferricin B, a peptide in milk with antimicrobial properties but only one fragment. LFeinB25 reduced the survival of human gastric adenocarcinoma cells .

The invewstigators saw microscopically after an hour of exposure to the gastric cancer cells, LFeinB25¬† migrated to the cell ,membranes of the gastric adenocarcinoma cells¬† and within 24 hours the cancer cells had shrunken in size and lost their ability to adhere to surfaces . In the early stages of exposure, LFeinB25 reduced cell viability through apoptosis (programed cell death) and autophagy (degredation and recycling of obsolete or damaged cell parts). At later stages apoptosis seemed to dominate and autophagy waned. The researcher said “”This iss the firsat report describing interplay between apoptosis and autophagy in LFeinB25 induced cell death of cancer cells.”
