New link between estrogen and breast cancer

---

Omschrijving
the female sex hormone estrogen turns on a gene linked to breast cancer, according to new research by Brisbane scientists. The cancer biology team from UQ's Diamantina Institute for Cancer, Immunology and Metabolic Medicine, believe their finding will help explain the link between breast cancer and high levels of estrogen. “What we've shown is that the ability of estrogen to switch this gene on is important for the growth of breast cancer cells,” Diamantina cancer biology research leader Professor Tom Gonda said. The gene they studied, known as MYB, is found in about 70 percent of all breast cancers and is one of several dozen genes called oncogenes that promote cancer growth. “What's important in breast cancer is the ability of estrogen to turn on MYB rather than there being a mutation in the gene itself,” Professor Gonda said.
