Novel bee venom derivative forms a nanoparticle 'smart bomb' to target cancer cells- (Aug, 2010 bioscience headlines)

New research in the FASEB Journal shows that a peptide derived from bee venom can deliver liposomes bearing drugs or diagnostic dyes to specific cells or tissues

The next time you are stung by a bee, here's some consolation: a toxic protein in bee venom, when altered, significantly improves the effectiveness liposome-encapsulated drugs or dyes, such as those already used to treat or diagnose cancer. This research, described in the August 2010 print issue of the FASEB Journal (http://www.fasebj.org), shows how modified melittin may revolutionize treatments for cancer and perhaps other conditions, such as arthritis, cardiovascular disease, and serious infections.

"This type of transporter agent may help in the design and use of more personalized treatment regimens that can be selectively targeted to tumors and other diseases," said Samuel A. Wickline, Ph.D., a researcher involved in the work from the Consortium for Translational Research in Advanced Imaging and Nanomedicine (C-TRAIN) at the Washington University School of Medicine in St. Louis, Missouri.

To make this discovery, Wickline and colleagues designed and tested variations of the melittin protein to derive a stable compound that could be inserted into liposomal nanoparticles and into living cells without changing or harming them. They then tested the ability of this protein, or "transporter agent," to attach to different therapeutic compounds and enhance drug therapy without causing harmful side effects. In addition, their results suggest that the base compound which is used to create the transporter agent may improve tumor therapy as well. Read more? >>
