Melanomas that develop resistance to vemurafenib also become addicted to the drug

Researchers in California and Switzerland have discovered that melanomas that develop resistance to the anti-cancer drug vemurafenib (marketed as Zelboraf), also develop addiction to the drug, an observation that may have important implications for the lives of patients with late-stage disease.

Blocking TRIP-Br2 gene protects against obesity and insulin resistance

Scientists observed that blocking the expression of the gene TRIP-Br2 in mice protects them against obesity and insulin resistance. The study shows that the gene modulates fat storage by regulating energy expenditure and lipolysis, the process which transforms fat into lipids for the body's energy consumption.

Taking early and repeated WBC is critical in determining infants at high risk of pertussis

A study released today from the upcoming issue of the Journal of the Pediatric Infectious Diseases Society (JPIDS) found that taking early and repeated white blood cell counts (WBC) is critical in determining whether infants have pertussis and which of those children are at highest risk of death from the disease.

Saliva gland test shows promise for Parkinson's

New research suggests that testing a portion of a person's saliva gland may be a way to diagnose Parkinson's disease.

Johns Hopkins develops PapGene test to diagnose ovarian and endometrial cancers

Using cervical fluid obtained during routine Pap tests, scientists at the Johns Hopkins Kimmel Cancer Center have developed a test to detect ovarian and endometrial cancers. In a pilot study, the "PapGene" test, which relies on genomic sequencing of cancer-specific mutations, accurately detected all 24 (100 percent) endometrial cancers and nine of 22 (41 percent) ovarian cancers. Results of the experiments are published in the Jan. 9 issue of the journal Science Translational Medicine.

Apparent stem cell transplant success in mice may hold promise for people with ALS

Apparent stem cell transplant success in mice may hold promise for people with amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease.

New information on insulin and cell bonding mechanics

The discovery of insulin nearly a century ago changed diabetes from a death sentence to a chronic disease. Today a team that includes researchers from Case Western Reserve University School of Medicine announced a discovery that could lead to dramatic improvements in the lives of people managing diabetes.

SLU researchers to test new screening method for MPS disorders among infants

Researchers at Saint Louis University have received a five-year, $2.5 million National Institutes of Health grant to test a new method of screening newborns for a group of rare, but serious genetic disorders that affect approximately 200 babies born in the U.S., each year.

H. pylori may protect against stroke and some cancers

A new study by NYU School of Medicine researchers reveals that an especially virulent strain of the gut bacterium Helicobacter pylori (H. pylori) isn't implicated in the overall death rate of the U.S. population, and may even protect against stroke and some cancers.

LM11A-31 effective at improving limb movement after spinal cord injury in mice

An experimental oral drug given to mice after a spinal cord injury was effective at improving limb movement after the injury, a new study shows.

UMDNJ develops rapid detection test for Exserhilum rostratum

A rapid detection test for Exserhilum rostratum, the fungus primarily responsible for 39 deaths among patients injected last year with a contaminated steroid medication, has been developed by a research team led by David S. Perlin, PhD, Executive Director of the Public Health Research Institute (PHRI) at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School.

Mutation that causes sickle cell anemia may offer new way to treat drug-resistant cancers

The genetic mutation that causes sickle cell anemia also turns red blood cells into potent tumor killers and may offer a new way to treat cancers that are resistant to existing treatments, according to research published January 9, 2013 in the open access journal PLOS ONE by David S. Terman of Jenomic Research Institute and colleagues from Duke University and other institutions.

TSRI chemists develop new cell-marking method

Chemists at The Scripps Research Institute (TSRI) have found an easier way to perform one of the most fundamental tasks in molecular biology. Their new method allows scientists to add a marker to certain cells, so that these cells may be easily located and/or selected out from a larger cell population.

Simple and inexpensive method to cut DNA could transform genetic medicine

A simple, precise and inexpensive method for cutting DNA to insert genes into human cells could transform genetic medicine, making routine what now are expensive, complicated and rare procedures for replacing defective genes in order to fix genetic disease or even cure AIDS.

Several genes may control body-fat responses to fast-food diets

Researchers at UCLA say it's not just what you eat that makes those pants tighter - it's also genetics. In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.

Researchers uncover genetic causes of von Willebrand disease

In 2006, the lab of Dr. David Ginsburg at the Life Sciences Institute put a call out for siblings attending the University of Michigan to donate blood for a study of blood-clotting disorders.

Fingolimod could potentially eliminate or reduce progression of colitis-associated cancer

After uncovering a mechanism that promotes chronic intestinal inflammation and the development of colorectal cancer, scientists from Virginia Commonwealth University Massey Cancer Center have found that fingolimod, a drug currently approved for the treatment of multiple sclerosis, could potentially eliminate or reduce the progression of colitis-associated cancer (CAC).
