Two tumor suppressor genes function to disrupt overactive EGFR signaling

Overactive epidermal growth factor receptor (EGFR) signaling has been linked to the development of cancer. Several drug therapies have been developed to treat these EGFR-associated cancers; however, many patients have developed resistance to these drugs and are therefore no longer responsive to drug treatment.

Inhibiting IRE1α-XBP1 pathway impacts survival of myeloma cells

Results published in Blood, the official journal of the American Society of Hematology, confirm that inhibition of the IRE1α-XBP1 pathway impacts the survival of myeloma cells, suggesting a promising therapeutic option in multiple myeloma.

Gene variant linked to postmenopausal fracture risk

Women who carry a variation in a gene involved in blocking bone morphogenic proteins are more likely to have fragility fractures than women without the variant, Greek research shows.

EMBO Journal highlights three decades of Wnt research

The impact and influence of thirty years of research into the Wnt/beta-catenin signaling pathway are highlighted in a special issue of The EMBO Journal.

Study shows how a drug-lead compound suppresses tumour formation

A team of scientists from the National University of Singapore's (NUS) Department of Biological Sciences and Mechanobiology Institute have discovered how a drug-led compound - a compound that is undergoing preclinical trials as a potential drug - can deprive cancer cells of energy and stop them from growing into a tumour. This drug-led compound is named BPTES.

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.
