Trial finds high-dose radiation effective for men whose prostate cancer has spread

A randomized clinical trial of targeted, high-dose radiation for men with oligometastatic prostate cancer has shown the treatment to be an effective and safe option for patients who wish to delay hormone-suppression therapy. The phase II trial found that radiation therapy can generate an immune system response not previously believed possible in this type of cancer.

Researchers developing new 'DNA stitch' to treat muscular dystrophy

A new therapeutic being tested is showing early promise as a more effective treatment that could help nearly half of patients with Duchenne muscular dystrophy (DMD). The treatment — a cocktail of DNA-like molecules — results in dramatic regrowth of a protein called dystrophin, which acts as a support beam to keep muscles strong. The protein is virtually absent in those with DMD.

Mystery underlying heart toxicity caused by diabetes drugs solved

For new diabetes medications, in which one drug aims to address the excess of lipids and glucose in the blood, the therapeutic benefits, while great, frequently are accompanied by dangerous toxic effects to the heart. Why and how these drugs cause heart dysfunction in diabetes patients has been unclear. Now, scientists show that certain diabetes drugs have a profound toxic effect on the generation and function of mitochondria.

New method provides better understanding of gene 'enhancers' work

Using anew method called Net-CAGE, researchers identified as many as 20,000 new enhancers in humans. They found that while promoters are activated in a variety of cell types, enhancers tend to function in just 1 cell type, thus showing an important difference between the 2 types of region.

New CRISPR class expands genetic engineering toolbox

Biomedical engineers have used a previously unexplored CRISPR technology to accurately regulate and edit target genes in human cells. With this new approach, the researchers hope to dramatically expand the CRISPR-based tools available to biomedical engineers, opening up a new and diverse frontier of genome engineering technologies.

Some parents pass on more mutations to their children than others

Everyone is a mutant but some are prone to diverge more than others, report scientists. A new study shows the number of mutations a child has compared to her parents varies dramatically with some people being born with twice as many as others, and that characteristic runs in families.

Discovery of how colorectal cancer drug works will help more patients

Some colorectal cancer patients with a certain gene mutation benefit from a chemotherapy drug called cetuximab, although the mechanism of how this drug worked was unknown. Scientists have combined computational biology with experimental investigations to discover, for the first time, the mechanism for why these patients respond to cetuximab, which will help doctors identify more effective, targeted treatment plans for people diagnosed with colorectal cancer.

Cellular senescence is associated with age-related blood clots

Cells that become senescent irrevocably stop dividing under stress, spewing out a mix of inflammatory proteins that lead to chronic inflammation as more and more of the cells accumulate over time. Researchers have identified 44 specific senescence-associated proteins that are involved in blood clotting, marking the first time that cellular senescence has been associated with age-related blood clots.
