Researchers untangle two distinct ways in which tumor-suppressor protein works

Researchers at the Stanford University School of Medicine have untangled two distinct ways in which a common, naturally occurring "tumor-suppressor" protein works.

Zaire ebolavirus may replicate in pigs and transmit to other animals

Canadian investigators have shown that a species of ebolavirus from Zaire that is highly virulent in humans can replicate in pigs, cause disease, and be transmitted to animals previously unexposed to the virus.

PCR testing for B. burgdorferi bacteria in joint fluid may confirm Lyme arthritis diagnosis

New research shows that polymerase chain reaction testing for Borrelia burgdorferi DNA—the spirochetal bacteria transmitted by deer ticks—in joint fluid may confirm the diagnosis of Lyme arthritis, but is not a reliable indicator for active joint infection in patients whose arthritis persists after antibiotic therapy. Findings of this study are published in Arthritis & Rheumatism, a journal of the American College of Rheumatology.

ISCO announces near-term marketing plans for Lifeline Skin Care products

International Stem Cell Corporation today announced the Company's near-term marketing plans for products manufactured by its Lifeline Skin Care subsidiary.

Notum gene plays a key role in planarian's regeneration decision-making process

A seldom-studied gene known as notum plays a key role in the planarian's regeneration decision-making process, according to Whitehead Institute scientists. Protein from this gene determines whether a head or tail will regrow at appropriate amputation sites.

Midbrain habenula region plays a key role in nicotine dependence

A person's vulnerability to nicotine addiction appears to have a genetic basis, at least in part. A region in the midbrain called the habenula plays a key role in this process, as Dr. In-s Iba-ez-Tallon and her team from the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now shown.

Researchers uncover unexpected role of estrogen receptors in brain inflammation

Researchers have uncovered an unexpected role for estrogen receptors in the brain in keeping inflammation under control. The findings reported in the May 13 issue of the Cell Press journal Cell may have important implications for the treatment of multiple sclerosis (MS) and many other neurodegenerative diseases.

Elevated levels of cardiac troponins T or I after angioplasty linked to long-term all-cause mortality

New research shows that elevated levels of cardiac troponin T (cTnT) or I (cTnI) in patients who had angioplasty indicate a higher risk of all-cause mortality and long-term adverse events such as heart attack.

New study sheds light on origins of myeloid leukemia

A new study by the NYU Cancer Institute, an NCI-designated cancer center, sheds light on the origins of myeloid leukemia, a type of blood cancer that affects children and adults.

UCSD scientists discover steroid hormone that inhibits brain inflammation

Researchers at the University of California, San Diego School of Medicine have discovered a steroid hormone that inhibits inflammation in the brain. The findings, to be published in the May 13 issue of the journal Cell, have implications for understanding the exaggerated inflammatory responses that are characteristic features of numerous neurodegenerative diseases.

CAMH scientist identifies gene responsible for Joubert syndrome

A new study involving Canada's Centre for Addiction and Mental Health has found a gene connected with a type of intellectual disability called Joubert syndrome.

Gene manipulation can improve survival rates during sepsis infection

Sepsis is a major killer in hospital intensive care units. Researchers at Case Western Reserve University School of Medicine have found that manipulating a genetic factor that can launch or throttle the body's defenses can improve survival rates during bacterial infection.

Study offers hints to why Parkinson's so selectively harms dopamine-producing cells

New data offer hints to why Parkinson's disease so selectively harms brain cells that produce the chemical dopamine, say researchers at Washington University School of Medicine in St. Louis.

Scientists discover enzyme that controls K-Ras gene responsible for lung cancer growth

Cancer Research UK scientists have discovered that an enzyme called C-Raf controls a hugely important gene responsible for the development of lung cancer, according to research published in Cancer Discovery.

New computational model can analyze living cells, social networks

At first glance, a diagram of the complex network of genes that regulate cellular metabolism might seem hopelessly complex, and efforts to control such a system futile. However, an MIT researcher has come up with a new computational model that can analyze any type of complex network - biological, social or electronic - and reveal the critical points that can be used to control the entire system.

Researchers identify miRNA in blood serum of lung cancer patients

Researchers have identified characteristic patterns of molecules called microRNA in the blood of people with lung cancer that might reveal both the presence and aggressiveness of the disease, and perhaps who is at risk of developing it.

Scientists uncover gene responsible for Adams-Oliver Syndrome

Scientists at King's College London have, for the first time, uncovered a gene responsible for Adams-Oliver Syndrome, a condition which can cause birth defects of the heart, limbs, or blood vessels.

Study provides evidence that adult planarians harbor pluripotent stem cells

A single adult cell from one of the most impressive masters of regeneration in the animal kingdom - the planarian - is all it takes to build a completely functional new worm, researchers have learned. The study provides the first hard evidence that adult planarians harbor pluripotent stem cells - cells capable of producing the diverse range of tissue types necessary to build a complete animal.

Mosquito's midgut bacteria can inhibit malaria parasite development

Researchers at the Johns Hopkins Bloomberg School of Public Health have identified a bacterium in field-caught mosquitoes that, when present, stops the development of Plasmodium falciparum, the parasite that causes malaria in humans.

New method for mapping myelin sheaths of nerve cells

Researchers including members from the Niels Bohr Institute at the University of Copenhagen have developed a new method for making detailed X-ray images of brain cells.
