Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Sabutoclax appears to selectively target leukemia stem cells that are responsible for relapses

Researchers at the University of California, San Diego School of Medicine have discovered that hard-to-reach, drug-resistant leukemia stem cells (LSCs) that overexpress multiple pro-survival protein forms are sensitive - and thus vulnerable - to a novel cancer stem cell-targeting drug currently under development.

Lack or excess of CaM kinase II affects heart muscle cell stiffness

A certain enzyme, the CaM kinase II, keeps the cardiac muscle flexible. By transferring phosphate groups to the giant protein titin, it relaxes the muscle cells. This is reported by researchers led by Prof. Dr. Wolfgang Linke of the Institute of Physiology at the Ruhr Universität in the journal Circulation Research. In failing hearts, which don't pump enough blood around the body, the scientists found an overly active CaM kinase II.

Octapharma receives FDA approval for Octaplas to treat blood clotting disorders

The U.S. Food and Drug Administration today approved Octaplas, a pooled plasma (human) blood product for the replacement of clotting proteins (coagulation factors) in certain medical conditions where patients have insufficient levels.

Head-scratching persists despite nodding syndrome study

Nodding syndrome is an epileptic disorder, with telltale nodding episodes caused by atonic seizures, concludes a pioneering study of the mysterious neurologic illness that has been reported in only three African countries.

Hypercoagulable markers identified in upper arm thrombosis patients

Coagulation tests are warranted in young women undergoing surgery for subclavian vein thrombosis, especially patients with Paget-Schroetter syndrome unrelated to physical activity, say US clinicians.

Potential stem cell therapy for Duchenne’s

Researchers have found that injecting aorta-derived stem cells into the hearts of dystrophin-deficient mice prevents the onset of dilated cardiomyopathy, raising hopes of a potential new treatment approach to prevent or reverse the condition in human Duchenne muscular dystrophy.

ELTD1 biomarker may help diagnose glioma

Researchers using sophisticated genetic testing techniques have identified a promising new biomarker for diagnosis of glioma—the most common type of malignant brain tumor, reports the January issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Eyes also need light to develop normally during pregnancy

New research in Nature concludes the eye – which depends on light to see – also needs light to develop normally during pregnancy.

Hepatitis B virus X protein represses miRNA-148a to enhance tumorigenesis

Viruses prompt oncogenic transformation by genetically altering infected cells. Several recent studies have demonstrated that viruses alter the expression of microRNAs, non-coding RNA molecules that can block the expression of target genes.

Positive gene therapy results in large mammals of Duchenne muscular dystrophy

Usually, results from a new study help scientists inch their way toward an answer whether they are battling a health problem or are on the verge of a technological breakthrough. Once in a while, those results give them a giant leap forward. In a preliminary study in a canine model of Duchenne muscular dystrophy (DMD), University of Missouri scientists showed exactly such a leap using gene therapy to treat muscular dystrophy.

Boehringer Ingelheim receives FDA Priority Review for afatinib to treat EGFR mutation-positive NSCLC

Boehringer Ingelheim today announced that the New Drug Application (NDA) for its investigational oncology compound afatinib has been accepted for filing and granted Priority Review by the U.S. Food and Drug Administration (FDA).

Scientists determine structure of Ltn1 protein

Using an innovative approach, scientists at The Scripps Research Institute (TSRI) have determined the structure of Ltn1, a recently discovered "quality-control" protein that is found in the cells of all plants, fungi and animals.

Astellas announces FDA acceptance of Tarceva sNDA for EGFR activating mutation-positive NSCLC

Astellas Pharma US, Inc., a U.S. subsidiary of Tokyo-based Astellas Pharma Inc., today announced that the U.S. Food and Drug Administration (FDA) has accepted for filing a supplemental New Drug Application (sNDA) for Tarceva (erlotinib) for first-line use in people with locally advanced or metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) activating mutations.

Protein Sciences receives FDA approval for Flublok vaccine

The U.S. Food and Drug Administration today announced that it has approved Flublok, the first trivalent influenza vaccine made using an insect virus (baculovirus) expression system and recombinant DNA technology. Flublok is approved for the prevention of seasonal influenza in people 18 through 49 years of age.

ARHGEF28 gene mutations present in amyotrophic lateral sclerosis: Research

Researchers at Western University in London, Canada, have identified a new genetic mutation for amyotrophic lateral sclerosis (ALS), opening the door to future targeted therapies. Dr. Michael Strong, a scientist with Western's Robarts Research Institute and Distinguished University Professor in Clinical Neurological Sciences at the Schulich School of Medicine & Dentistry, and colleagues found that mutations within the ARHGEF28 gene are present in ALS.
