Johns Hopkins scientists identify DNA-damaging substances in food

In a laboratory study pairing food chemistry and cancer biology, scientists at the Johns Hopkins Kimmel Cancer Center tested the potentially harmful effect of foods and flavorings on the DNA of cells.

Research findings could lead to improved treatment for neuropathic pain

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, says a key protein in Schwann cells performs a critical, perhaps overarching, role in regulating the recovery of peripheral nerves after injury.

Exosomes can transfer membrane proteins, study reveals

Important new research from UMass Medical School demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference, and directly target disease-carrying cells.

Environmental enrichment increases endogenous cell migration, facilitates functional repair

A team of Korean researchers investigated whether "environmental enrichment" can improve the neurobehavioral function of six week-old mice after transplantation of adipose-derived stem cells to treat hypoxic-ischemic brain injury, and found that brain repair (neurogenesis) was aided in some animals through exercise-induced fibroblast growth factor 2 (FGF2), a strong pro-angiogenic factor.

IDIBELL signs agreement with Histocell to use patent for acute pulmonary diseases with stem cells

The Bellvitge Biomedical Research Institute has signed a licensing agreement with the Spanish biotech company Histocell to make use of a patent for the treatment of acute pulmonary diseases with mesenchymal stem cells.

Researchers shed new light on role of methylation in gene expression

Researchers at UC Davis and the University of British Columbia have shed new light on methylation, a critical process that helps control how genes are expressed.

Researcher discovers genetic variations that are linked to breast cancer

Working with an international consortium conducting research on breast, ovarian and prostate cancer among 200,000 people, Professor Jacques Simard, holder of the Canada Research Chair in Oncogenetics at Laval University, was actively involved in the discovery of DNA "spelling mistakes" linked to breast cancer.

New laboratory study shows certain protein particles multiply, spread from one cell to another

In diseases like Alzheimer's and Parkinson's endogenous proteins accumulate in the brain, eventually leading to the death of nerve cells. These deposits, which consist of abnormally formed proteins, are supposed to migrate between interconnected areas of the brain, thereby contributing to the development of the illness.

Study links genetic variation, wheezing illness to childhood asthma risk

About 90 percent of children with two copies of a common genetic variation and who wheezed when they caught a cold early in life went on to develop asthma by age 6, according to a study to be published March 28 by the New England Journal of Medicine.

New research sheds light on natural mechanism that protects ears from hearing loss

New research from the Massachusetts Eye and Ear, Harvard Medical School and Harvard Program in Speech and Hearing Bioscience and Technology may have discovered a key piece in the puzzle of how hearing works by identifying the role of the olivocochlear efferent system in protecting ears from hearing loss.

New study associates commonly used diabetes drugs with pancreatic cancer risk

ndividuals who had taken a type of drug commonly used to treat Type 2 diabetes showed abnormalities in the pancreas, including cell proliferation, that may be associated with an increased risk of neuroendocrine tumors, according to a new study by researchers from UCLA and the University of Florida.

Researchers reprogramming skin cells into brain cells to understand Alzheimer's disease

Sam Gandy, MD, PhD, of the Icahn School of Medicine at Mount Sinai is leading an international team of researchers working to reprogram skin cells into brain cells to gain a better understanding of Alzheimer's disease.

Pancreatic cancer cells' growth are fueled by metabolic pathway, scientists find

Dana-Farber Cancer Institute scientists and colleagues have discovered that pancreatic cancer cells' growth and spread are fueled by an unusual metabolic pathway that someday might be blocked with targeted drugs to control the deadly cancer.

Scientists discover new mechanism that regulates replication of insulin-producing beta cells in pancreas

Bringing scientists a step closer to new treatments for diabetes, researchers at the University of Pittsburgh School of Medicine and The Mount Sinai Medical Center have discovered a novel mechanism that regulates the replication of insulin-producing beta cells in the pancreas.

Microbiologists identify unique resistance mechanisms of E. coli to carbapenems

As public health authorities across the globe grapple with the growing problem of antibiotic resistance, Tufts University School of Medicine microbiologists and colleagues have identified the unique resistance mechanisms of a clinical isolate of E. coli resistant to carbapenems.

Researcher receives grant to enhance human tissue dissection, reduce blood transfusions during surgery

A George Washington University researcher recently received a grant to study ways to cut human tissue more efficiently, an effort that could minimize the need for blood transfusions and other products for patients during surgery.

Fruit flies raised on organic diets record better health outcomes

A new study looking at the potential health benefits of organic versus non-organic food found that fruit flies fed an organic diet recorded better health outcomes than flies fed a nonorganic diet.

Study: Gene therapy can boost heart muscle function

In an animal study, researchers at the University of Washington show that it is possible to use gene therapy to boost heart muscle function. The finding suggests that it might be possible to use this approach to treat patients whose hearts have been weakened by heart attacks and other heart conditions.

Study raises alarm over loss of individual 'genomic liberty' due to gene patents

Humans don't "own" their own genes, the cellular chemicsals that define who they are and what diseases they might be at risk for. Through more than 40,000 patents on DNA molecules, companies have essentially claimed the entire human genome for profit, report two researchers who analyzed the patents on human DNA. Their study, published March 25 in the journal Genome Medicine, raises an alarm about the loss of individual "genomic liberty."
