Rutgers cell biologist to receive Presidential Early Career Award for Scientists and Engineers

Fewer than 100 researchers nationwide are chosen each year to receive the Presidential Early Career Award for Scientists and Engineers (PECASE), and this year Dr. Nihal Altan-Bonnet is one of the 96 to receive this honor.

Experts examine host recognition of Staphylococcus and E.coli bacteria

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often completely unnoticeable elimination of the invaders. Their immune-activating abilities were only detected in 1998, a discovery which was awarded with the Nobel Prize

Simple sponge may hold clues about the evolution of the complex nervous system

UC Santa Barbara scientists turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all.

Study identifies existence of an antitumor molecule that originates within SMYD3 oncogene

A common point in all human tumors is that they produce an activation of oncogenes, genes that cause cancer and they also cause a loss of function of the protective genes, called anti-oncogenes or tumour suppressor genes. Normally both categories of anticancer and procancer genes are in different regions of our chromosomes.

Breakthrough in understanding the causes of unexplained male infertility

The diagnosis of male fertility is usually performed through the observation of the sperm in the microscope. However, a normal quality semen does not guarantee an adequate fertility. In fact, there is a considerable proportion of cases of unexplained infertility and data suggest that abnormal sperm function may have a genetic or molecular origin.

Chemists produce first high resolution structure of HCV viral RNA-inhibitor complex

Chemists at the University of California, San Diego have produced the first high resolution structure of a molecule that when attached to the genetic material of the hepatitis C virus prevents it from reproducing.

Researchers produce extensive catalog of genes expressed in human islets

A new JDRF-funded study shows that many of the genes known to play a role in type 1 diabetes (T1D) are expressed in pancreatic beta cells, suggesting that the cell responsible for producing insulin may be playing a part in its own destruction to lead to T1D.

Complex computer program helps analyze RNA structural motifs

Computer engineers may have just provided the medical community a new way of figuring out exactly how one of the three building blocks of life forms and functions.

New way to awaken paternal Ube3a allele linked with Angelman syndrome

Results of a new study from the University of North Carolina at Chapel Hill may help pave the way to a treatment for a neurogenetic disorder often misdiagnosed as cerebral palsy or autism.

Ribosomes spontaneously change their form during protein production

Ribosomes, the construction sites for proteins, are far more complex than previously assumed. During the production of proteins they constantly and spontaneously change their form. This performance of eukaryotic ribosomes has now been demonstrated for the first time by scientists at Charité - Universitätsmedizin Berlin, the Max-Planck-Institut für Molekulare Genetik in Berlin, and Cornell University in New York, with the aid of special electron microscopic and biophysical methods.

X-chromosome related microRNA may impact immunity and cancer

As anyone familiar with the phrase 'man-flu' will know women consider themselves to be the more robust side of the species when it comes to health and illness. Now new research, published in BioEssays, seems to support the idea. The research focuses on the role of MicroRNAs encoded on the X chromosome to explain why women have stronger immune systems to men and are less likely to develop cancer.

Close link between SF3B1 mutation and specific feature of myelodysplastic syndromes

Geneticists have discovered that a gene involved in the modification of ribonucleic acid (RNA) is mutated in a significant proportion of people with a collection of blood cancers called myelodysplastic syndromes.

New nanopore sensor can lead to early detection of lung cancer

When lung cancer strikes, it often spreads silently into more advanced stages before being detected. In a new article published in Nature Nanotechnology, biological engineers and medical scientists at the University of Missouri reveal how their discovery could provide a much earlier warning signal.

Scientists uncover unknown fail-safe pathway for inherited disorders

Scientists at the University of California, San Diego School of Medicine have uncovered a previously unknown fail-safe (compensatory) pathway that potentially protects the brain and other organs from genetic and environmental threats.

MAVS prion-like proteins are involved in innate immunity: Discovery

A person's ability to battle viruses at the cellular level remarkably resembles the way deadly infectious agents called prions misfold and cluster native proteins to cause disease, UT Southwestern Medical Center researchers report.

Scientists uncover novel mechanism linked to Spinocerebellar ataxia 7

A team of scientists, led by researchers at the University of California, San Diego School of Medicine, have uncovered a novel mechanism regulating gene expression and transcription linked to Spinocerebellar ataxia 7, an inherited neurological disorder.

Hepatitis C virus (HCV)-associated liver disease after liver transplantation

Hepatitis C virus (HCV)-associated liver disease continues to be the most common indication for liver transplantation (LT) in the United States accounting for nearly 50% of all liver transplants. Recurrence is universal in patients viremic at the time of transplantation with histological hepatitis developing in the majority of patients. Although the natural history of recurrent HCV is difficult to predict, it is widely accepted that cirrhosis from recurrent HCV occurs in up to 30% of patients within five years of transplantation.

Hepatitis C patients with chronic liver disease may benefit from drinking coffee during treatment

Advanced hepatitis C patients with chronic liver disease may benefit from drinking coffee during treatment, according to a new study in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute.

DFG to form new collaborative research centers as of 1 July 2011

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish 21 new Collaborative Research Centres (CRCs) as of 1 July 2011. This was decided by the relevant Grants Committee at its spring meeting in Bonn.

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.
