Wasp Venom Selectively Assassinates Cancer Cells
Many wasp species have chemicals in their venom that kill bacteria. In the last few years, researchers have found that some of these chemicals also kill cancer cells, though exactly how they work has remained a mystery.Now a new study has described exactly how one of these chemicals works its cancer-fighting magic: by tearing holes in the cancer cells’ outer layer.

Marked for Destruction
The venom of the Brazilian wasp Polybia paulista contains a molecule called MP1. It’s been previously found that MP1 can inhibit the growth of prostate and bladder cancer cells, as well as multi-drug-resistant leukemia, but it doesn’t harm healthy cells.But the question was how. Researchers suspected that the answer lay in the cells’ membranes. That’s because the cancer cells that MP1 targets have two fatty molecules, or lipids, in their external membrane that normal cells don’t have.These lipids – phosphatidylserine (PS) and phosphatidylethanolamine (PE) – now seem to be the signposts that mark a cancer cell for destruction.http://blogs.discovermagazine.com/d-brief/2015/09/01/wasp-venom-cancer/#.Vec7dLVVat8
