Scientists Unravel Role of Fusion Gene in Prostate Cancer, Weill Cornell Medical College Study

Tue, 05/22/2012 - 8:00pm
Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth. Now, Weill Cornell Medical College researchers have found that in these cancer cells, the 3-D architecture of DNA, wrapped up in a little ball known as a chromatin, is warped in such a way...

Snoring Linked to Cancer, University of Wisconsin-Madison Study

Can Skin Cells Repair Damaged Heart Tissue? Study

Tue, 05/22/2012 - 8:00pm
People who suffer from heart failure could someday be able to use their own skin stem cells to regenerate their damaged heart tissue, according to a new Israeli study. Researchers took stem cells from the skin of two patients with heart failure and genetically programmed them to become new heart muscle cells. They then transplanted the new cells into healthy rats and found that the cells integrated...

Northwestern University Study Ties Genes to Lower Urinary Tract Symptoms, Prostate Cancer Risk

Tue, 05/22/2012 - 8:00pm
Certain gene variants linked to prostate cancer may make men more susceptible to lower urinary tract symptoms, according to a new study. On the other hand, a different gene variant might protect against those symptoms, the study found. Researchers from the Feinberg School of Medicine at Northwestern University in Chicago identified 38 genetic sequence variants linked to prostate cancer risk in nearly...

Disagreeable People Prefer Aggressive Dogs, University of Leicester Study

Tue, 05/22/2012 - 8:00pm
Aggressive dog ownership is not always a sign of attempted dominance or actual delinquency. A study carried out at the University of Leicester's School of Psychology has found that younger people who are disagreeable are more likely to prefer aggressive dogs, confirming the conventional wisdom that dogs match the personality of their owners.

Fat Removal Reduces Skin Cancer in Mice, Rutgers University Study

Mon, 05/21/2012 - 8:00pm
The surgical removal of abdominal fat resulted in 75-80 percent fewer UV-induced skin cancers among obese mice fed a high-fat diet. When it comes to humans, scientists cant say if liposuction or other fat removal procedures are beneficial for treating obesity and reducing the risk of cancer. Although they know that obesity increases the risk of heart disease, diabetes, and cancer, there have not been...
