A unique nanoscale drug that can carry a variety of weapons and sneak into cancer cells to break them down from the inside has a new component: a protein that stimulates the immune system to attack HER2-positive breast cancer cells.

Combined therapy could repair and prevent damage in Duchenne muscular dystrophy, study suggests

Posted: 10 Aug 2013 03:37 AM PDT

New research on two promising gene therapies suggests that combining them into one treatment not only repairs muscle damage caused by Duchenne muscular dystrophy, but also prevents future injury from the muscle-wasting disease. The work is the first to look at the approach in aged mice, a key step toward clinical trials in patients.

Successful treatment of triple negative breast cancer by modulation of the OGF-OGFr axis

Posted: 10 Aug 2013 03:36 AM PDT

Human triple-negative breast cancer can be treated by modulation of the opioid growth factor (OGF) - OGFr pathway. OGF suppresses cell growth by 20 percent within 24 hours in a receptor-mediated manner. Blockade of OGFr using low dosages of the opioid antagonist naltrexone causes a compensatory increase in OGF and results in 35 percent reductions in cell number within 72 hours. These data demonstrate a novel biological pathway for treatment of this deadly breast cancer.

Cigarette taxation helps to reduce drinking among groups considered vulnerable

A new study has examined the effects of cigarette taxation on alcohol consumption. Results suggest that increases in cigarette taxes are associated with modest to moderate reductions in alcohol consumption among vulnerable groups. Vulnerable groups include hazardous drinkers, young adult smokers, and smokers in the lowest income category.
