Research reveals unconventional production of specialized T cells essential for balanced immune system

New findings from St. Jude Children's Research Hospital reveal an unconventional control mechanism involved in the production of specialized T cells that play a critical role in maintaining immune system balance. The research appears in the current online edition of the scientific journal Nature.

Reading books and participating in brain-stimulating activities may preserve memory

New research suggests that reading books, writing and participating in brain-stimulating activities at any age may preserve memory. The study is published in the July 3, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Human gene expression mechanism opens new therapeutic strategies against neurological disease

In a study that could change the way scientists view the process of protein production in humans, University of Chicago researchers have found a single gene that encodes two separate proteins from the same sequence of messenger RNA.

Study shows miR-22 plays a key role in breast and blood cancers

A mere 25 years ago, noncoding RNAs were considered nothing more than "background noise" in the overall genomic landscape. Now, two new studies reveal that one of these tiny noncoding molecules - microRNA-22 - plays an outsized role in two types of cancer.

Texas scientists develop new medium for cultivation of beneficial microorganisms

Texas A&M University System scientists from the departments of nutrition and food science and poultry science have developed a new medium for the cultivation of beneficial microorganisms called lactobacilli.

Discovery sheds new light on aggressiveness of certain breast cancers

In a discovery that sheds new light on the aggressiveness of certain breast cancers, Whitehead Institute researchers have identified a transcription factor, known as ZEB1, that is capable of converting non-aggressive basal-type cancer cells into highly malignant, tumor-forming cancer stem cells (CSCs). Intriguingly, luminal breast cancer cells, which are associated with a much better clinical prognosis, carry this gene in a state in which it seems to be permanently shut down.

Study: Different strains of alpha-synuclein may contribute to different types of brain diseases

It only takes one bad apple to spoil the bunch, and the same may be true of certain proteins in the brain. Studies have suggested that just one rogue protein (in this case, a protein that is misfolded or shaped the wrong way) can act as a seed, leading to the misfolding of nearby proteins.

Research shows over 50% of tumors have mutations in p53

Researchers of the Cancer Metabolism group at the Bellvitge Biomedical Research Institute (IDIBELL), Catalan Oncology Institute (ICO) and the Division of Hematology-Oncology of the University of Cincinnati, led by George Thomas, have discovered a role for ribosomal 5S RNA in the formation of a complex that regulates the stability of p53.

Study shows activated blood platelets enable cancer cells to penetrate blood vessels

Malignant tumours often spread to remote areas of the body. In the majority of cases, metastases formation develops via the blood vascular system. The blood platelets thereby provide invaluable help to the tumour cells in penetrating new organs.

Scientists identify molecular signals that spur the formation of arteries

The ability to form blood vessels is one of evolution's crowning achievements, and something that separates vertebrates (animals with a backbone) from the rest of the animal kingdom.

Researchers produce potential antibiotic that targets bacterial enzyme critical to metabolic processes

University of Adelaide research has produced a potential new antibiotic which could help in the battle against bacterial resistance to antibiotics.

Mothers commonly talk to children about genetic test even it they test positive for gene mutation

Mothers commonly talk to their children about genetic test results even if they test positive for a BRCA1 or BRCA2 gene mutation, which sharply increases a woman's risk of developing breast and ovarian cancer.

Scientists discover network for molecular communication in human embryonic stem cells

Scientists at A*STAR's Genome Institute of Singapore (GIS) and the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin (Germany) have discovered a molecular network in human embryonic stem cells (hESCs) that integrates cell communication signals to keep the cell in its stem cell state.

Study says screening heart with natriuretic peptide may reduce risk of dysfunction, heart failure

Among patients at risk of heart failure, collaborative care based on screening for certain levels of brain-type natriuretic peptide reduced the combined rates of left ventricular systolic dysfunction, diastolic dysfunction, and heart failure as well as emergency cardiovascular hospitalizations, according to a study in the July 3 issue of JAMA.

Growing brain aneurysms 12 times more likely to burst, says new UCLA study

Brain aneurysms of all sizes—even small ones no larger than a pea—are up to 12 times more likely to rupture if they are growing, according to a new UCLA study.

Metastasis can occur when leukocyte and cancer cell fuse to form genetic hybrid

Yale Cancer Center scientists, together with colleagues at the Denver Police Crime Lab and the University of Colorado, have found evidence that a human metastatic tumor can arise when a leukocyte (white blood cell) and a cancer cell fuse to form a genetic hybrid.

Genetic variations can identify women who are likely to benefit from breast cancer prevention drug

Scientists found genetic variations that could be used to identify women who are most likely to benefit from a certain type of breast cancer prevention drug—and who should avoid it.

Researchers pinpoint role of Arl13b gene in guiding placement of neurons during brain development

Researchers have pinpointed the role of a gene known as Arl13b in guiding the formation and proper placement of neurons in the early stages of brain development. Mutations in the gene could help explain brain malformations often seen in neurodevelopmental disorders.

Researchers identify two promising candidates for development of drugs to combat adenovirus

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have identified two promising candidates for the development of drugs against human adenovirus, a cause of ailments ranging from colds to gastrointestinal disorders to pink eye.

Researchers report that aerobic exercise can lessen or worsen ulcerative colitis symptoms

Aerobic exercise can lessen - or worsen - the symptoms of inflammatory bowel diseases such as ulcerative colitis, depending on the circumstances under which the exercise is undertaken, researchers report.
