Platypus Study Answers Questions About Gene Imprinting
Can a platypus get cancer? It was a moot question until recent research revealed that the oddball egg-layer shares a propitious trait with people. This genetic feature lowers the risk for cancer, challenges the notion that mice make the best cancer models, and may even have implications in human cloning.
It all began when radiation oncologist Randy Jirtle, Ph.D., of Duke University Medical Center, Durham, N.C., became interested in a gene for the receptor of insulin-like growth factor-II (IGF2R; also called M6P/IGF2R because the receptor binds the protein mannose-6-phosphate as well). Jirtle and his team identified IGF2R, important in prenatal and postnatal growth and development,
