Genetic mutation found to restore translational balance in mice

In a biological quirk that promises to provide researchers with a new approach for studying and potentially treating Fragile X syndrome, scientists at the University of Massachusetts Medical School (UMMS) have shown that knocking out a gene important for messenger RNA (mRNA) translation in neurons restores memory deficits and reduces behavioral symptoms in a mouse model of a prevalent human neurological disease.

New research identifies internal timepiece that accurately gauge age of human organs and tissues

Everyone grows older, but scientists don't really understand why. Now a UCLA study has uncovered a biological clock embedded in our genomes that may shed light on why our bodies age and how we can slow the process.

Scientists find unexpected molecular switch that prompts blood stem cells aging

Scientists report in Nature they have found a novel and unexpected molecular switch that could become a key to slowing some of the ravages of getting older as it prompts blood stem cells to age.

Research: Learning mentally demanding skill likely to improve cognitive functioning

Older adults are often encouraged to stay active and engaged to keep their minds sharp, that they have to "use it or lose it." But new research indicates that only certain activities - learning a mentally demanding skill like photography, for instance - are likely to improve cognitive functioning.

Study finds inherited GATA3 gene variation increases risk of developing pediatric leukemia

Research led by St. Jude Children's Research Hospital scientists has linked an inherited gene variation to a nearly four-fold increased risk of developing a pediatric acute lymphoblastic leukemia (ALL) subtype that is associated with a poor outcome.

Clarified role of signal-relay proteins may help explain spread of cancer

Cell biologists at The Johns Hopkins University have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.

Researchers identify key therapeutic target for cancers driven by KRAS protein

Patients with cancers driven by the protein KRAS, which are particularly hard to treat, may benefit from small molecules that attach to and disrupt the function of a KRAS-containing protein complex, according to results presented here at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, held Oct. 19-23.

Study: Pds5 proteins modulate behavior of cohesins to ensure proper division of cells

Cohesins are protein complexes that join the two copies of each chromosome-called sister chromatids-to ensure that they are shared fairly between the daughter cells during cell division. In this way, each daughter cell receives exactly the same genetic information from the parent cell.

RNA-based gene expression test potentially determine presence or absence of BRAF V600E mutation

Veracyte, Inc., a molecular diagnostics company pioneering the field of molecular cytology, today announced preliminary study results suggesting the potential for an RNA-based gene expression test to accurately detect the BRAF V600E gene mutation in thyroid nodule fine needle aspiration (FNA) samples.

Study: Skin tanning gene linked to higher risk for testicular cancer in white men

A gene important in skin tanning has been linked to higher risk for testicular cancer in white men, according to a study led by scientists from the U.S. National Institutes of Health and the University of Oxford in England.

Research: Hypermutation in cancer is more frequent in inactive X chromosome

Every case of cancer originates from changes in a person's genetic material (mutations). These usually occur as "somatic mutations" in individual cells during an individual's lifetime, rather than being inherited from a person's parents.

Sugary drink consumption among young children spikes 8% in California

While consumption of soda and other sugary drinks among young children in California is starting to decline, a new study released today shows an alarming 8 percent spike among adolescents, the biggest consumers of these beverages.

Study shows significant link between low dietary fiber intake and cardiometabolic risks

A new study published in the December issue of The American Journal of Medicine shows a significant association between low dietary fiber intake and cardiometabolic risks including metabolic syndrome, cardiovascular inflammation, and obesity.

Oral nutritional supplements linked with decreased probability of 30-day hospital readmission

In the U.S., one in five Medicare patients is readmitted to a hospital each year at an estimated cost of $17.5 billion annually.i To reduce this impact, the Affordable Care Act (ACA) has introduced hospital penalties based on readmissions conditions that commonly affect patients aged 65 and older - including acute myocardial infarction, congestive heart failure and pneumonia.
