Men at Risk

1 Bad Behaviors Decrease When Men Become Dads

At-risk behaviors decrease when men become fathers for the first time, says a 19-year study of 200 boys who were assessed annually from the ages of 12 to 31 to learn how crime, tobacco, marijuana and alcohol use changed over time. Prior studies showed that men’s negative behaviors improved after marriage. Data indicates that men in their late 20s and early 30s showed greater decreases in crime and alcohol use compared to men who became fathers in their teens or early 20s. "... fatherhood can be a transformative experience, even for men engaging in high risk behavior," says lead author David Kerr. "This presents a unique window of opportunity for intervention, because new fathers might be especially willing and ready to hear a more positive message and make behavioral changes."

Forces Cells to Use Estrogen

2 Aggressive Breast Cancer Made Treatable

A new study conducted at the University of Colorado School of Medicine has found that the estrogen receptor-negative breast cancer cells can become estrogen-receptor positive by inhibiting Notch protein activity. Tumors with estrogen receptors that treatments like tamoxifen target often contain a subpopulation of cells without them. When the receptor-positive cells are killed by anti-estrogen therapy, receptor-negative cells predominate which do not respond to treatment. But they do have Notch receptors so they can use the Notch protein to grow and multiply but blocking this allows them to revert to using estrogen. Clinical trials involving Notch inhibitors are underway and researchers believe combining them with anti-estrogens would make treatment more effective.
