Scientists identify why African naked mole-rat feels no pain when exposed to acid

British researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world's most unusual mammals, feels no pain when exposed to acid.

Hebrew University student wins Kaye Innovation Award for anti-cancer therapy

A strategy for inhibiting a protein that is associated with the spread of cancer has won for a Hebrew University of Jerusalem Ph.D. student in chemistry one of this year's Kaye Innovation Awards at the university.

Short spiral-shaped proteins can efficiently deliver DNA segments to cells

Clinical gene therapy may be one step closer, thanks to a new twist on an old class of molecules. A group of University of Illinois researchers, led by professors Jianjun Cheng and Fei Wang, have demonstrated that short spiral-shaped proteins can efficiently deliver DNA segments to cells. The team published its work in the journal Angewandte Chemie.

H2S plays critical role in signaling pathway linked to Alzheimer's and Parkinson's

Something rotten never smelled so sweet. This is what members of a team of scientists at Cold Spring Harbor Laboratory (CSHL) are telling one another as they discuss a new finding they did not expect to make. They have discovered that hydrogen sulfide (H2S) - the flammable, highly toxic gas that we usually associate with the smell of rotten eggs in landfills and sewers - plays an important role in the regulation of a signaling pathway implicated in biological malfunctions linked to Alzheimer's and Parkinson's diseases, among others.

CTI, Chroma announce final results from tosedostat phase II study on AML

Cell Therapeutics, Inc. and Chroma Therapeutics Ltd. announced that final results from the phase II OPAL study of tosedostat in elderly patients with relapsed or refractory acute myeloid leukemia (AML) were presented by Jorge Cortes, M.D. of the University of Texas M.D. Anderson Cancer Center during the Acute Myeloid Leukemia - Therapy, excluding Transplantation: Clinical Studies session at the American Society of Hematology Annual Meeting.

Geron commences GRN1005 Phase 2 trial in breast cancer

Geron Corporation today announced the initiation of GRABM-B (GRN1005 Against Brain Metastases - Breast cancer), a Phase 2 clinical trial to evaluate GRN1005 in patients with brain metastases arising from breast cancer.

Scientists identify importance of novel protein-regulating mechanism

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open up opportunities to develop new types of drugs for diseases such as cancer.

Evaluation method supports soy as high-quality protein

The importance of protein in the human body is undeniable. However, the idea of what makes a protein a "quality protein" has not been as easy to determine. A new study from the Journal of Agriculture and Food Chemistry takes a closer look at the criteria for determining the quality of a protein.

Study shows new biochemical disturbances in the brains of children with ADHD

A new study at örebro University in Sweden shows that children with ADHD have nearly 50 percent less of a protein that is important for attention and learning. The finding may mean that there are other biochemical disturbances in the brains of individuals with ADHD than was previously believed.

NIH-led study advances HIV vaccine research

HIV is coated in sugars that usually hide the virus from the immune system. Newly published research reveals how one broadly neutralizing HIV antibody actually uses part of the sugary cloak to help bind to the virus. The antibody binding site, called the V1/V2 region, represents a suitable HIV vaccine target, according to the scientists who conducted the study. In addition, their research reveals the detailed structure of the V1/V2 region, the last part of the virus surface to be visualized at the atomic level.

Arginine may reactivate T-cells in patients with glioblastoma

In many cases, tumors suppress a patient's immune system in a way that keeps the cancer safe from immune system attack. This is particularly true for patients with glioblastoma, a primary brain tumor that carries a prognosis of only 12-15 months survival after diagnosis.

WSU receives NHLBI grant to develop new CF treatments

A Wayne State University research team led by Fei Sun, Ph.D., assistant professor of physiology in the School of Medicine, recently received a grant with an anticipated amount of nearly $1.9 million from the National Heart, Lung and Blood Institute of the National Institutes of Health to better understand how this defective protein in cystic fibrosis patients is prematurely digested.

Study reveals specific functional deficit in inner ear mechanotransduction channels

National Institutes of Health-funded researchers have identified two proteins that may be the key components of the long-sought after mechanotransduction channel in the inner ear-the place where the mechanical stimulation of sound waves is transformed into electrical signals that the brain recognizes as sound.

EUSA Pharma receives FDA approval for Erwinaze to treat ALL

The U.S. Food and Drug Administration today approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy (hypersensitivity) to E. coli derived asparaginase and pegaspargase chemotherapy drugs used to treat ALL.

Protein, not sugar, stimulates cells keeping us thin and awake

A new study has found that protein and not sugar activates the cells responsible for keeping us awake and burning calories. The research, published in the 17 November issue of the scientific journal Neuron, has implications for understanding obesity and sleep disorders.

Researchers discover human genes that might contribute to ALS

Amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, is a universally fatal neurodegenerative disease. Mutations in two related proteins, TDP-43 and FUS, cause some forms of ALS. Specifically, these two proteins are RNA-binding proteins that connect to RNA to regulate the translation of proteins and other cellular functions such as RNA splicing and editing. In a new study, researchers at the Perelman School of Medicine at the University of Pennsylvania discovered additional human genes with properties similar to TDP-43 and FUS that might also contribute to ALS.

Long-term AED therapy may increase risk of atherosclerosis in epilepsy patients

New research reveals that patients with epilepsy who were treated for extended periods with older generation antiepileptic drugs (AEDs) may be at increased risk for developing atherosclerosis, a common disorder known as hardening of the arteries.

Scientists identify factors that lead to concomitant tumor resistance

Scientists are another step closer to understanding what drives tumor metastasis, as laboratory models suggest there are factors inside tumors that can slow their own growth.
