TGen, UA receive NFCR grant to study targeted pancreatic cancer therapies

The Translational Genomics Research Institute (TGen) and the University of Arizona (UA) have received a three-year, $600,000 grant to study targeted cancer therapies from the National Foundation for Cancer Research.

Certain strains of P. aeruginosa cause WBCs to produce high levels of histamine

Could some cases of asthma actually be caused by an allergic reaction to a common environmental bacteria? New research findings published in the Journal of Leukocyte Biology suggests that this idea may not be as far-fetched as it seems. In a research report appearing in the February 2012 print issue, researchers show a link between common environmental bacteria and airway inflammation.

Specific gene mutation triggers development of NAFLD

A team of scientists from the University of Utah and the University of California at San Francisco has discovered that the mutation of a gene encoding a ketone body transporter triggers accumulation of fat and other lipids in the livers of zebrafish.

Study finds no link between BDV and psychiatric illness

Over the past 30 years, numerous studies have linked Borna disease virus (BDV) with mental illnesses such as bipolar disorder, schizophrenia, anxiety disorder and dementia. Genetic fragments and antibodies to this RNA virus, which causes behavior disorders in a range of mammals and birds, have been found to be prevalent in psychiatric patients, but study results have been inconsistent. Now, the first blinded, case-control study to examine this issue finds no association between the virus and psychiatric illness.

Scientists discover different brain regions cooperate during short-term memory

Holding information within one's memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window. Yet, despite the apparent simplicity of these actions, short-term memory is a complex cognitive act that entails the participation of multiple brain regions. However, whether and how different brain regions cooperate during memory has remained elusive.

Crizotinib can treat ROS1-driven tumors

A report from investigators at the Massachusetts General Hospital (MGH) Cancer Center has defined the role of a recently identified gene abnormality in a deadly form of lung cancer. Tumors driven by rearrangements in the ROS1 gene represent 1 to 2 percent of non-small-cell lung cancers (NSCLC), the leading cause of cancer death in the U.S.

Scientists identify TDO enzyme as new target for cancer therapy

Scientists from the Ludwig Institute for Cancer Research (LICR) in Brussels identified a new target for cancer therapy, an enzyme which prevents the immune system from recognizing and destroying certain types of tumors.

Kras gene plays a role in continuous growth of pancreatic cancer

A mutant protein found in nearly all pancreatic cancers plays a role not only in the cancer's development but in its continued growth, according to a new study from University of Michigan Comprehensive Cancer Center researchers. The finding suggests a possible target for developing new ways to treat this deadly disease.

Pneumonic plague bacteria transform lungs into a playground for microbes to flourish

Among medical mysteries baffling many infectious disease experts is exactly how the deadly pneumonic plague bacterium, Yersinia pestis, goes undetected in the first few day of lung infection, often until it's too late for medical treatment.

Nanosize titanates may inhibit growth of oral cancer and bacterial cell lines

Sometimes bigger isn't better. Researchers at the U.S. Department of Energy's Savannah River National Laboratory have successfully shown that they can replace useful little particles of monosodium titanate (MST) with even tinier nano-sized particles, making them even more useful for a variety of applications.

New technology helps scientists observe Parkinson's cell development

In the US alone, at least 500,000 people suffer from Parkinson's disease, a neurological disorder that affects a person's ability to control his or her movement. New technology from the University of Bonn in Germany lets researchers observe the development of the brain cells responsible for the disease.

Researchers investigate Avian Pathogenic E. coli strains

Escherichia coli bacteria thrive in the lower intestine of humans and other animals, including birds. Most are vital constituents of the healthy gut flora, but certain forms of E. coli cause a range of diseases in both humans and poultry.

Fluorescence microscopy reveals 3-D picture of myoV's transport capacity

A new study in the Journal of General Physiology uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) "walk" along their actin track.

Link between maternal nurturing and size of hippocampus in healthy children

School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. The new research, by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, is the first to show that changes in this critical region of children's brain anatomy are linked to a mother's nurturing.

Small molecules at the cell’s membrane enable cell movement

Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell’s skeletal shape and drive the cell’s movement.

Study investigates trade-off between sperm quality and immunity

A new study shows the production of sperm is more biologically taxing than previously thought, and expending energy on it has significant health implications.

Lycopene can kill prostate cancer cells

A nutrient in cooked tomatoes has been shown in laboratory studies to slow the growth of or even kill prostate cancer cells.

HSP40/70 linked to hepatitis C infection

Researchers from UCLA's Jonsson Comprehensive Cancer Center have identified a cell-permeable peptide that inhibits a hepatitis C virus protein and blocks viral replication, which can lead to liver cancer and cirrhosis.

Study pinpoints genetic factors behind increased ALL risk in Hispanic children

Hispanic children are more likely than those from other racial and ethnic backgrounds to be diagnosed with acute lymphoblastic leukemia (ALL) and are more likely to die of their disease. Work led by St. Jude Children's Research Hospital scientists has pinpointed genetic factors behind the grim statistics.
