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.

Study validates Mitofusin 2 as possible target for treatment of diabetes mellitus

Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have discovered that deficiency of a single protein, Mitofusin 2, in muscle and hepatic cells of mice is sufficient to cause tissues to become insensitive to insulin, thus producing an increase in blood glucose concentrations. These are the two most common conditions prior to development of diabetes type 2.

Deficiency of Mitofusin 2 protein leads to insulin resistance, glucose intolerance

The study shows that the lack of Mitofusin 2 in mice produces insulin resistance and glucose intolerance, the main causes of diabetes.

Researchers identify Wnt pathway as new target for scleroderma therapy

A genetic pathway previously known for its role in embryonic development and cancer has been identified as a target for systemic sclerosis, or scleroderma, therapy.

HGF/C-MET signaling pathway plays a key role in gestational diabetes development

Researchers at the University of Pittsburgh School of Medicine have identified a cell-signaling pathway that plays a key role in increasing insulin secretion during pregnancy and, when blocked, leads to the development of gestational diabetes.

Researchers discover critical placental niche cell and signaling pathway

UCLA stem cell researchers have discovered a critical placental niche cell and signaling pathway that prevent blood precursors from premature differentiation in the placenta, a process necessary for ensuring proper blood supply for an individual's lifetime.

Similar mechanisms drive changes in puberty

It's one of life's special moments: a child finds a fat caterpillar, puts it in a jar with a twig and a few leaves, and awakens one day to find the caterpillar has disappeared and an elegant but apparently lifeless case now hangs from the twig.

Ruxolitinib boosts QOL and survival for patients with myelofibrosis

A drug that relieves the severe symptoms of a life-threatening bone marrow cancer called myelofibrosis also improves the survival of patients with the disease, according to a phase III clinical trial published in the March 1 edition of New England Journal of Medicine.

CNRS/Inserm researchers discover new family of anti-cancer compounds

A French-Italian team headed by researchers from CNRS and Inserm has discovered a new family of compounds that could make it possible to treat numerous cancers, particularly brain tumors and skin cancers.

Scientists identify specific mechanisms by which vitamin D inhibits inflammation

Researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. In their experiments, they showed that low levels of Vitamin D, comparable to levels found in millions of people, failed to inhibit the inflammatory cascade, while levels considered adequate did inhibit inflammatory signaling.

Can-Fite receives FDA Orphan Drug Status for CF102 to treat hepatocellular carcinoma

Can-Fite BioPharma Ltd, a biotechnology company developing small molecule drugs for the treatment of inflammatory, and liver diseases, traded on the Tel Aviv Stock Exchange, announced today that the US Food and Drug Administration (FDA) has granted Orphan Drug Status for its drug candidate, CF102, for the treatment of hepatocellular carcinoma.

IKK2 enzyme plays a key role in proliferation of lung cancer cells

Drugs targeting an enzyme involved in inflammation might offer a new avenue for treating certain lung cancers, according to a new study by scientists at the Salk Institute for Biological Studies.

Researchers identify potent regulator of sensitivity to insulin

Researchers at Washington University School of Medicine in St. Louis have identified a potent regulator of sensitivity to insulin, the hormone that controls blood sugar levels. The new findings may help scientists find better treatments for type 2 diabetes, obesity and other health problems caused by the body's inability to properly regulate blood sugar.

Researchers pinpoint source of Loeys-Dietz syndrome

A USC research team has pinpointed the source of a genetic disorder that causes life-threatening birth defects, which may allow doctors to quickly diagnose and better treat the disease.
