Dual functions of gene revealed, for better and for worseMay 27, 2008Researchers at WEHI have pinpointed the function of a potent cancer gene. The gene, known as "ERG", has long been associated with a range of human malignancies, including leukemia and sarcoma. American scientists showed in 2005 that ERG is mutated in more than half of all prostate cancers. It was unclear, however, what function ERG normally performs in the human body and why it is so carcinogenic when mutated. The team at WEHI has now demonstrated that ERG's usual role is to regulate the activity of blood stem cells. Without ERG, these cells cannot divide normally and the body fails to generate the trillions of blood cells that required each day to carry oxygen and fight infection. The study suggests that ERG causes cancer by convincing normal cells to behave like stem cells, triggering unrestrained growth and expansion. The findings offer hope that the targets of ERG might now be open to identification, which in the future might lead to new drugs that shut down the proliferation of cancer cells. Research Australia |

Mammography may increase breast cancer risk in some high-risk women Low-dose radiation from annual mammography screening may increase breast cancer risk in women with genetic or familial predisposition to breast cancer, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). New cancer gene discovered A new cancer gene has been discovered by a research group at the Sahlgrenska Academy. The gene causes an insidious form of glandular cancer usually in the head and neck and in women also in the breast. The discovery could lead to quicker and better diagnosis and more effective treatment.
