Your poison can reduce cancerous tumors

The poison of the wasp Polybia paulista contains a powerful ingredient to combat the Cancer without affecting thehealthy cells , revealed a study by researchers from the State University of Sao Paulo and the University of Leeds (United Kingdom).

Brazilian and British researchers have studied how a molecule of the toxin acts on cells, which has the ability to discriminate between cancer cells and healthy, attacking only the first ones.

The study published in the Biophysical Journal details that poison this wasp It contains a molecule called MP1 (Polybia-MP1), which inhibits the growth of prostate cancer cells and bladder cancer, as well as leukemia.

Scientists suspect that the answer lies in the membranes of cells, since the cancer cells they have two fat molecules in their outer membrane, that normal cells do not have: phosphatidylserine (PS) and phosphatidylethanolamine (PE).

 

Cancer therapies that attack the lipid composition of the cell membrane could be a new class of anti-cancer drugs, "explained study co-author Paul Beales of the University of Leeds.

The results suggest that MP1 could be a good candidate for a treatment of future cancer. If it were to work, it would be the first cancer drug on the market that focuses on the lipid membranes of cells.
