Cancer Research

> Researchers say that inhibiting the Bmi-1 gene would help slow the most aggressive types of cancer. "We conclude by these results that Bmi-1 is a crucial regulator of self-renewal in adult prostate cells and plays important roles in prostate cancer initiation and progression," said Dr. Owen Witte. "It was encouraging to see that inhibiting this protein slows the growth of even a very aggressive prostate cancer, because that could give us new ways to attack this disease." Report


> Researchers say that the DRD4 gene, already linked to alcohol use and gambling, could also play a role in spurring a propensity for brief sexual liaisons. Story

> Scientists have found dozens of genes that play a role in autism as well as other brain disorders. "As we continue to uncover genetic mutations that can cause autism, we are gaining further insights that will lead to earlier diagnosis and better treatments," said Dr. Joseph Buxbaum. Report
