Cancer-related pathway reveals potential treatment target for rare pediatric disease

TORONTO -- Cancer researchers studying genetic mutations that cause leukemia have discovered a connection to the rare disease cherubism, an inherited facial bone disorder in children.

The link is the enzyme Tankyrase and its pivotal role in switching on or off the protein that controls two known cancer genes. In normal cells, the protein is vital for bone development. In abnormal cells, it is thought to be involved in two common types of blood cancer – chronic myelogenous leukemia and acute myeloid leukemia.

Toronto researchers obtain detailed molecular 'signature' for Tankyrase

Toronto, ON -- The Samuel Lunenfeld Research Institute's Drs. Frank Sicheri, Tony Pawson and Sebastian Guettler, in collaboration with Dr. Robert Rottapel at the Ontario Cancer Institute, have uncovered the detailed architecture of a crucial component of Tankyrase, a protein linked to the bone development disorder cherubism and involved in a myriad of cellular processes. The discovery is the first structural insight into precisely how the enzyme correctly identifies its targets, or substrates.

Personalized treatment for Crohn's Disease a step closer following gene mapping

Three new locations for Crohn's Disease genes have been uncovered by scientists at UCL using a novel gene mapping approach.

Breakthrough in regulating fat metabolism

Scientists at Warwick Medical School have made an important discovery about the mechanism controlling the body's 'fat switch', shedding new light on our understanding of how proteins regulate appetite control and insulin secretion.

First genome sequencing clinical trial for triple negative cancer points to new treatments

PHOENIX, Ariz. -- Initial results from an ongoing clinical trial, the first designed to examine the utility of whole-genome sequencing for triple negative breast cancer, were reported today during the CRTC-AACR San Antonio Breast Cancer Symposium.

Study shows species can change

A study of South American songbirds completed by the Department of Biology at Queen's University and the Argentine Museum of Natural History, has discovered these birds differ dramatically in colour and song yet show very little genetic differences which indicates they are on the road to becoming a new species.

Climate change driving tropical birds to higher elevations

DURHAM, N.C. -- Tropical birds are moving to higher elevations because of climate change, but they may not be moving fast enough, according to a new study by Duke University researchers.

The study, published Thursday in the peer-reviewed online journal PLoS ONE, finds that the birds aren't migrating as rapidly as scientists previously anticipated, based on recorded temperature increases.

The animals instead may be tracking changes in vegetation, which can only move slowly via seed dispersal.

Study: Supplemental reading programs work better when aligned with core curricula

Students who struggle with reading get an extra benefit from a supplemental reading program when its content is aligned with the students' core reading curriculum, according to a study published in the December issue of the Elementary School Journal.

The findings suggest that supplemental reading programs work best when they mirror core curricula in scope and sequence rather than simply being "layered on top," write the study's authors, Carla Wonder-McDowell, D. Ray Reutzel (Utah State University), and John A. Smith (University of Texas-Arlington).

New imaging agent has an appetite for dangerous prostate tumors

Non-invasive imaging detects prostate cancer earlier than ever before, but can't accurately distinguish between malignant and benign disease. According to Lawson Health Research Institute's Drs. John Lewis and Len Luyt, a new molecular imaging probe could be the answer.

Ghrelin is a growth hormone produced by the stomach and pancreas to stimulate hunger. Malignant prostate cancer cells are known to consume it at much higher rates than normal prostate cells. The Lawson team believed this could be the key to singling out aggressive disease.

New study is first to test the actual impact of branded apps on consumers

BLOOMINGTON, Ind. -- A new research study co-authored by an Indiana University professor suggests that interactive applications for mobile phones such as Apple's iPhone and Google's Android may be some of the most powerful forms of advertising yet developed.

Promising results in mice on needle-free candidate universal vaccine against various flu viruses

Scientists from the International Vaccine Institute (IVI) have discovered that an antigen common to most influenza viruses, and commonly referred to as matrix protein 2 (M2), when administered under the tongue could protect mice against experimental infection caused by various influenza viruses, including the highly pathogenic avian H5 virus and the pandemic H1 ("swine flu") virus.

Study sheds light on cancer burden in Australia

Over the past quarter century in Australia, cancer incidence rates have increased while deaths from cancer have steadily decreased. Those are some of the findings of a recent study published early online in the Asia-Pacific Journal of Clinical Oncology.

Early lineage of Larkspur and Monkshood plants rediscovered in Southern Europe

Larkspurs, monkshoods, and aconites are plants, widely cultivated for their beauty and medicinal properties. They all belong to the Delphinieae, a natural group of 650-700 species ranging from Eurasia into North America, with a few species on tropical African mountains. The study was published in the open access journal PhytoKeys.

Women advised to avoid ZEN bust-enhancing supplements because of possible cancer risk

Women who use bust-enhancing dietary supplements containing the mycoestrogen zearalenone (ZEN), a naturally occurring toxin that widely contaminates agricultural products, could be increasing their risk of breast cancer. That is the warning from breast health experts in a paper published online ahead of print publication in the January issue of IJCP, the International Journal of Clinical Practice.
