Improved-resolution views of a zinc transporter protein deciphered

New, improved-resolution views of a zinc transporter protein deciphered at the U.S. Department of Energy's Brookhaven National Laboratory provide not just a structure but also a suggested mechanism for how cells sense and regulate zinc, an element that is essential for life, but which must be kept at a steady state to avoid problems like seizures, diabetes, and possibly Alzheimer's disease.

Death stench is a warning sign to prevent diseases

The smell of recent death or injury that repels living relatives of insects has been identified as a truly ancient signal that functions to avoid disease or predators, biologists have discovered.

Researchers discover two proteins controlling the stem cell switch to skin cells

Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, in collaboration with colleagues at the Centro de Investigaciones Energ-ticas, Medioambientales y Tecnologicas (CIEMAT) in Madrid, have discovered two proteins that control when and how these stem cells switch to being skin cells.

Monoamine oxidases responsible for personality and behaviour

Antisocial and aggressive behaviours represent a widespread and expensive social problem. Recent research has convincingly shown that there is a strong interaction between genetic inheritance and environment for development of personality and behaviour.

Mayo study raises hope for treating multiple sclerosis

A Mayo Clinic study has found that two genes in mice were associated with good central nervous system repair in multiple sclerosis (MS). These findings give researchers new hope for developing more effective therapies for patients with MS and for predicting MS patients' outcomes. This study will be presented at the Congress of the European Committee for Treatment and Research in Multiple Sclerosis in Dusseldorf, Germany, on Sept. 11, 2009.

Elderberry extract prevents H1N1 infection in vitro

A recent research study has given new scientific evidence to the long-held empirical belief that elderberries possess antiviral activities. The research involved a specific, reproducible elderberry extract developed by HerbalScience Group LLC, and succeeded in identifying key chemical components of the extract that inhibited in vitro infection and were shown to bind directly to Human Influenza A (H1N1) virus particles. The binding blocked the ability of the viruses to enter host cells, and thereby effectively preventing H1N1 infection in vitro.

Wisconsin researchers identify the genetic region responsible for cardiovascular collapse during anesthesia

Researchers at The Medical College of Wisconsin in Milwaukee have identified the genetic region in rats responsible for cardiovascular collapse during anesthesia. While it is well known that people have different cardiovascular sensitivity to anesthesia causing some to collapse even when low doses are administered, the mechanism responsible for this susceptibility is not clear.

New stem cell technology could destroy breast cancer cells

GENova Biotherapeutics, Inc., ("GENova"), released important information about its innovative method for destroying breast cancer cells, using stem cell technology.

Cellular mechanosensory system may yield new insights for cancer therapy

Every moment, millions of a body's cells flawlessly divvy up their genes and pinch perfectly in half to form two identical progeny for the replenishment of tissues and organs - even as they collide, get stuck, and squeeze through infinitesimally small spaces that distort their shapes.

Biomarker Discovery Service from Arrayit to unravel mystery of genetic links for human disease states

Arrayit Corporation (OTCBB: ARYC), a proprietary life sciences technology leader, is making available a Biomarker Discovery Service capable of identifying multiple new major genetic links for human disease states which have remained a mystery for years. In separate technology collaborations, Arrayit has conducted confidential experiments which have successfully proven the unique capabilities of the custom Arrayit products and protocols employed in the Biomarker Discovery Service.

Researchers discover the role of endothelin in vaso-occlusive pain

Agonizing physical pain, known as vaso-occlusive pain, can afflict children who have sickle cell disease (SCD). In some cases infants as young as two months of age suffer vaso-occlusive pain so severe that opiate medications and hospitalizations are their only relief. Researchers believe vaso-occlusion is caused by a blockage of the blood vessels that occurs when sickle shaped red cells attempt to pass through the round blood vessels.

eChIP genetic technique developed to examine FA proteins with DNA crosslinks

While Fanconi anemia (FA) is a rare and dangerous disease, new laboratory research at The University of Texas M. D. Anderson Cancer Center shows it may lead researchers toward clues in more common diseases, including highly hereditary types of breast cancer.

UTSA receives grant from NSF to study nanomaterials

The University of Texas at San Antonio (UTSA) has received a five-year, $2.7 million grant from the National Science Foundation (NSF) to study nanomaterials and their biomedical applications.

New study reveals that actual sex ratios can sway from the ideal

In a perfect world, for every boy there would of course be a girl, but a new study shows that actual sex ratios can sometimes sway very far from that ideal. In fact, the male-to-female ratio of one tropical butterfly has shifted rapidly over time and space, driven by a parasite that specifically kills males of the species, reveals a report published online on September 10th in Current Biology, a Cell Press publication.

Fau and MELK genes may help improve breast cancer diagnosis and treatment

Researchers at Keele University have identified two genes which may help improve the diagnosis and treatment of breast cancer patients.

TrKA and CCM2 combination results in pediatric tumour regression

Why are some pediatric cancers able to spontaneously regress? Prof. Michael Fainzilber and his team of the Weizmann Institute's Biological Chemistry Department seem to have unexpectedly found part of the answer. Further research towards a better understanding of the mechanism of action might hopefully lead, in the future, to the development of drugs that will be able to induce regression of certain tumors.

Scientist awarded grant to study the role of VENs in quick decision making

A scientist at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center has been awarded a $400,000 grant from the James S. McDonnell Foundation to help study a rare cell type that is believed to play a role in quick decision making and intuition. Abnormalities in this cell type have been seen in people suffering from autism and dementia.

Endothelin research update to be presented at APS' 11th International Conference

Recent research to block the effects of endothelin, a powerful substance that constricts blood vessels and stimulates cell growth, has led to successful treatment of pulmonary arterial hypertension and provides hope for treating other chronic diseases.

Research on the role of microRNAs in cellular processes

RNAs, serving as a mere intermediary between DNA and proteins, were long regarded as a poor relation by researchers, attracting little interest. However, following the discovery of small RNAs known as microRNAs, they have increasingly been moving into the limelight. MicroRNAs bind to messenger RNA (mRNA), thereby regulating the translation of genes into proteins.

Research reveals genetic conversation between X and Y chromosomes

In the week that the University of Leicester celebrates the 25th anniversary of the discovery of DNA fingerprinting (Thursday September 10) new findings from the world-renowned University of Leicester Department of Genetics reveal for the first time that the male and female do truly communicate -at least at the fundamental genetic level.
