British and Brazilian researchers have discovered that the poison of murder is killing cancer cells without eliminating healthy ones.
Joint study between State University of Sao Paulo (UNESP) and University of Leeds (United Kingdom) recently published in the American Medical Journal Biophisical Journal reveals that the MP-1 peptide is present in the poison of the axis Poliana Paulista, common in Brazil, slows down the proliferation of malignant cells from prostate, bladder and leukemia.
"Cancer therapies that attack the cell membrane lipid composition can assume a new and complete class of cancer drugs. It can be very useful in developing new combined therapies, in which several drugs are used simultaneously for the treatment of cancer, while attacking different parts of the cancer cells," says molecular biologist Paul Beales, co-author of the study.
The MP-1 peptide only adheres to the cancer cell with excess lipids in its membranes rather than the healthy cell.
