Scientists discover key biochemical step underlying heart failure

Some 5.8 million Americans suffer from heart failure, a currently incurable disease. But scientists at Temple University School of Medicine's (TUSM) Center for Translational Medicine have discovered a key biochemical step underlying the condition that could aid the development of new drugs to treat and possibly prevent it.

Shortage of TDP-43 protein causes muscle wasting and stunted nerve cells

A shortage of a protein called TDP-43 caused muscle wasting and stunted nerve cells. This finding supports the idea that malfunction of this protein plays a decisive role in ALS and FTD. The study is published in the "Proceedings of the National Academy of Sciences of the USA" (PNAS).

UMDNJ biochemist to research into mechanisms that control gene expression in mitochondria

Dmitry Temiakov, PhD, a biochemist at the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine, has received a five-year, $1.5 million grant from the National Institutes of Health (NIH) to fund research into the molecular mechanisms that control gene expression in mitochondria, the organelles that are the "power plants" of cellular activity.

Blocking aPKC activity can stop growth of transplanted skin tumors resistant to vismodegib

Hailed as a major step forward in the effort to develop targeted cancer therapies, a recently approved drug for the most common type of skin cancer has been a mixed blessing for patients. Although the initial response is usually dramatic, the tumors often recur as the cancer becomes resistant to treatment.

Researchers map complex interactions of proteins that control inflammation

Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it.

Researchers discover new way to accelerate mass spectrometer that identifies proteins

Researchers at the University of Wisconsin-Madison have found a new way to accelerate a workhorse instrument that identifies proteins. The high-speed technique could help diagnose cancer sooner and point to new drugs for treating a wide range of conditions.

Schistosome stem cells could explain how the worms survive for so many years

The parasites that cause schistosomiasis, one of the most common parasitic infections in the world, are notoriously long-lived. Researchers have now found stem cells inside the parasite that can regenerate worn-down organs, which may help explain how they can live for years or even decades inside their host.

Disruption in the body's circadian rhythm can increase risk of diabetes, heart disease

Disruption in the body's circadian rhythm can lead not only to obesity, but can also increase the risk of diabetes and heart disease.

GCP could help lengthen life expectancy of certain prostate cancer patients

A natural, nontoxic product called genistein-combined polysaccharide, or GCP, which is commercially available in health stores, could help lengthen the life expectancy of certain prostate cancer patients, UC Davis researchers have found.

Earlier may be better for neurostimulation in Parkinson’s

Adding neurostimulation to best medical therapy boosts quality of life in patients with relatively early-stage Parkinson’s disease, shows a randomized trial.

Two studies discover new enzyme that acts as a sensor of innate immunity

Two studies by researchers at UT Southwestern Medical Center could lead to new treatments for lupus and other autoimmune diseases and strengthen current therapies for viral, bacterial, and parasitic infections.

Researchers discover SCANR that helps protect a cell's genes against DNA interlopers

Gene wars rage inside our cells, with invading DNA regularly threatening to subvert our human blueprint. Now, building on Nobel-Prize-winning findings, UC San Francisco researchers have discovered a molecular machine that helps protect a cell's genes against these DNA interlopers.

Ability to tune gene activity will permit refined research for drug resistance, cancer

Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.

RNF20 protein required for MLL-rearranged leukemia amplification

Acute myeloid leukemia (AML) is an aggressive blood cancer that is currently incurable in 70% of patients. In a bold effort, CSHL scientists are among those identifying and characterizing the molecular mechanisms responsible for this cancer in order to generate potential new therapeutics.

Scientists create nanoscale vehicle to battle cancer without harming healthy cells

A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment. Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.

New method can determine seriousness of cancer prognosis with 80% certainty

The number of incorrect cancer prognoses can be halved with computerised image analysis. In three years time, the method can be used on patients with bowel cancer, ovarian cancer and prostate cancer.

Previously poorly investigated signalling pathway crucial for proliferation of prostate cancer cells

A previously poorly investigated signalling pathway is crucial for the growth and proliferation of prostate cancer cells. An international research team discovered this when studying the enzyme "soluble adenylyl cyclase" that produces the second messenger molecule cAMP.

Study provides new insight on cancer prevention

Clear communication between cells is essential to every aspect of the body's internal function. But since cells can't talk, or send emails, how do they communicate?

Erbin protein critical to brain excitement

Scientists have found an early step in how the brain's inhibitory cells get excited. A natural balance of excitement and inhibition keeps the brain from firing electrical impulses randomly and excessively, resulting in problems such as schizophrenia and seizures. However excitement is required to put on the brakes.
