Study uncovers mechanism by which Notch pathway could contribute to RA

A new study led by researchers at Hospital for Special Surgery identifies the mechanism by which a cell signaling pathway contributes to the development of rheumatoid arthritis (RA). In addition, the study provides evidence that drugs under development for diseases such as cancer could potentially be used to treat RA.

Researchers map processes that power health benefits of omega-3 fatty acids

For the first time, researchers at the University of California, San Diego have peered inside a living mouse cell and mapped the processes that power the celebrated health benefits of omega-3 fatty acids. More profoundly, they say their findings suggest it may be possible to manipulate these processes to short-circuit inflammation before it begins, or at least help to resolve inflammation before it becomes detrimental.

Mass. Eye and Ear announces recipients of 2012 Curing Kids Fund grants

The Mass. Eye and Ear Curing Kids fund has awarded grants for research projects that aim to help the brain locate sound, identify genes that cause congenital blindness, cure deafness through hair cell regeneration, and improve treatment for childhood eye cancer.

mTOR protein plays a key role in development of diabetes

The signaling protein mTOR is a key regulator that controls cell growth. Dysfunction of mTOR increases not only the likelihood of developing cancer but also diabetes. In the current issue of the journal Cell Metabolism, Mike Hall and his team from the Biozentrum of the University of Basel describe how inhibition of mTOR signaling can impair carbohydrate metabolism and potentially lead to diabetes.

Study: Breast cancer in young women is enriched with aggressive basal-like tumors

Breast cancer in young women is a biologically unique disease that requires customized management strategies, researchers report at the 4th IMPAKT Breast Cancer Conference, in Brussels, Belgium.

FDA approves Novartis’ Afinitor for treatment of renal angiomyolipomas and TSC

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.

Soy protein may reduce fat accumulation, triglycerides in the livers of obese persons

University of Illinois scientists report that soy protein may significantly reduce fat accumulation and triglycerides in the livers of obese persons. And they've discovered why it happens: soy restores partial function of that organ's key signaling pathway.

March of Dimes selects UTMB scientist to receive Basil O'Connor Starter Scholar Award

The March of Dimes Foundation has chosen University of Texas Medical Branch at Galveston assistant professor Muge Kuyumcu-Martinez to receive a two-year, $150,000 Basil O'Connor Starter Scholar Award. The grant will support her research on congenital heart defects, the most common type of major birth defect.

New study describes therapeutic approach to halt cancer progression

A new study describes a therapeutic approach to halting cancer progression by exploiting a previously unrecognized "addiction" of leukemia cells to specific signaling molecules. The research, published by Cell Press online on April 16th in the journal Cancer Cell, identifies non-classical oncogenes critical for tumor development and survival, and describes a potentially less toxic strategy that selectively targets these molecules.

$Researchers identify 32 genetic regions associated with osteoporosis, fracture$

Researchers identify 32 genetic regions associated with osteoporosis, fracture

Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, MD, DSc. Variations in the DNA sequences in these regions confer either risk or protection from the bone-weakening disease. Many, but not all, of the regions encode proteins involved in pathways known to involve bone health.

Study contains warning for obese expectant mother

A new University of Illinois study contains a warning for obese women who are planning pregnancies. Even if they eat a healthy diet when they are pregnant, their babies will develop in an unhealthy environment that places the infants at risk for future health problems.

Scientists transform skin cells directly into induced neurons

Until recently, the production of pluripotent "multipurpose" stem cells from skin cells was considered to be the ultimate new development. In the meantime, it has become possible to directly convert cells of the body into one another - without the time-consuming detour via a pluripotent intermediate stage. However, this method has so far been rather inefficient.

Novel anti-leukemia compound with little toxicity successfully treats zebrafish

A novel anti-leukemia compound with little toxicity successfully treated zebrafish with T-cell acute lymphoblastic leukemia (T-ALL), suggesting its potential to become a new highly targeted therapy for humans - even those resistant to conventional therapies - according to results from a study published online today in Blood, the Journal of the American Society of Hematology (ASH).

Scientists discover why rapamycin causes diabetic-like symptoms in patients

Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing.

MEK1 mutation does not necessarily make BRAF mutant melanomas resistant to inhibitors

A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true.

Aberrations in translation regulators linked with hormone receptor-positive breast cancer survival

Four proteins involved in translation, the final step of general protein production, are associated with poor prognosis in hormone-receptor-positive breast cancer when they are dysregulated, researchers reported at the AACR Annual Meeting 2012.

Disrupting mTORC1 protein complex extends lifespan

One of the secrets to a longer, healthier life is simply to eat less. When subjected to calorie restriction (CR), typically defined as a 20-40% reduction in caloric intake with corresponding maintenance of proper nutrition, animals in labs not only live longer, but also have improved insulin sensitivity and glucose tolerance, both of which decline during aging.

Researchers identify new population of intestinal stem cells

Vanderbilt-Ingram Cancer Center researchers have identified a new population of intestinal stem cells that may hold clues to the origin of colorectal cancer.

Pfizer to present data on ADCs at AACR 2012

Pfizer Oncology will present data from a variety of preclinical and clinical studies of Pfizer's early-stage compounds, including data from Pfizer's investigational antibody-drug conjugate (ADC) portfolio and research evaluating several molecules targeting novel pathways that play a crucial role in basic cellular functions, at the American Association for Cancer Research (AACR) Annual Meeting 2012 in Chicago, IL, from March 31-April 4.
