Progress toward understanding the role of sex hormones in the growth of prostate cancer—the most common cancer in U.S. men—has been hindered by the lack of a suitable laboratory research model. Now researchers say they have developed the first model of hormone-induced human prostate cancer initiation and progression.

The vitamin folate appears to promote healing in damaged rat spinal cord tissue by triggering a change in DNA, according to a laboratory study funded by the National Institutes of Health. The researchers showed that the healing effects of the vitamin increased with the dosage, until regrowth of the damaged tissue reached a maximum level.

A protein whose primary role is in the embryonic development of kidneys may play a future role in treating kidney failure. Indiana University School of Medicine researchers have successfully treated acute kidney injury in laboratory experiments using cells that were genetically reprogrammed to produce the protein.

Dr. Kelvin Jones is looking at exercise as a new way to slow the degenerative processes of ALS, commonly known as Lou Gehrig’s disease. Jones, a recipient of a 2009 ALS Canada Discovery Grant, has been pioneering research in this field for four years, using mice genetically altered to present familial ALS. He’s found that exercise has a positive impact on the mice, slowing the disease significantly.

Researchers at Northwestern University Feinberg School of Medicine have identified in mice a previously unknown protective mechanism by which the smallest blood vessels remove blood clots and other blockages from the brain. The findings provide insights into mechanisms that may be involved in age-related cognitive decline, Alzheimer’s disease and recovery from stroke.

As scientists engaged in biomedical research, we all know how important animal research is to our lives. When we or our loved ones take medicine, undergo minimally invasive surgery, receive vaccines to prevent polio or hepatitis, or even take a pet to the veterinarian, we have benefitted from health advances made possible through decades of responsible, regulated animal research - SfN President Michael E. Goldberg.
