How Huntington's disease proteins move from cell to cell

One bad apple is all it takes to spoil the barrel. And one misfolded protein may be all that's necessary to corrupt other proteins, forming large aggregations linked to several incurable neurodegenerative diseases such as Huntington's, Parkinson's and Alzheimer's.

Doctor explores link between lack of oxygen and inflammation in patients undergoing surgery

When the body is deprived of oxygen during a major surgery, the kidneys, heart muscles or lungs can be injured as a result. The problem is that lack of oxygen can lead to inflammation.

Scientists establish biomarker strategy to diagnose variety of cancer types

A team of biologists, clinical oncologists, pathologists and information scientists has established a strategy for identifying biomarkers. If a particular pattern of these biomarkers can be detected in the blood, this indicates a cancerous disease. An interdisciplinary research breakthrough that opens many doors.

Cyclacel's CYC065 CDK inhibitor demonstrates potential against breast cancer resistant to trastuzumab

Cyclacel Pharmaceuticals, Inc., today announced the publication of preclinical data in the Proceedings of the National Academy of Sciences (PNAS), demonstrating that cyclin E plays a major role in making Human Epidermal growth factor Receptor 2 positive (HER2+) breast cancer resistant to trastuzumab (Herceptin®), a widely used medicine for breast cancer patients who test positive for HER2.

Rare bleeding disorder misdiagnosed

A rare bleeding disorder that can lead to life-threatening bleeding episodes is misdiagnosed in 15 per cent of cases according to findings from a new international research project led by a Queen's professor.

Deactivation of CRTC1 protein increases lifespan

Substantial evidence suggests that lifespan is increased if an organism restricts its daily calorie intake, a spartan regime that some say works by just making life seem longer. A team of scientists from the Salk Institute of Biological Studies has discovered a molecular switch flipped by hunger that could not only make longevity more appetizing but identify drug targets for patients with aging-related diseases such as type II diabetes or cancer.

Muscle, aptly enough, is born of cellular bullying, and not mutual consent

In fact, according to new research from Johns Hopkins, the fusion of muscle cells is a power struggle that involves a smaller mobile antagonist that points at, pokes and finally pushes into its larger, stationary partner using a newly identified finger-like projection.

Study: Overexpression of EZH2 protein promotes breast cancer progression

An essential protein for normal stem cell renewal also promotes the growth of breast cancer stem cells when it's overproduced in those cells, researchers at The University of Texas MD Anderson Cancer Center report in the February edition of Cancer Cell.

New research finds differences in cell fate commitment during embryonic development in mammals

New research shows that all not mammals are created equal. In fact, this work shows that the animals most commonly used by scientists to study mammalian genetics -- mice -- develop unusually quickly and may not always be representative of embryonic development in other mammals.

Study shows beneficial anti-fibrotic effects of Pentraxin-2 in idiopathic pulmonary fibrosis

Promedior, Inc., a clinical stage biotechnology company developing novel therapies to treat fibrotic and inflammatory diseases, announced today the publication of collaborative research in the International Journal of Biochemistry and Cell Biology entitled, "TGF-beta driven lung fibrosis is macrophage dependent and blocked by Serum amyloid P."

Spinal cord sugar residues regulate growth and survival of nerve cells: Study

Researchers in Bochum have found out that certain sugar residues in the spinal cord regulate the growth and survival of nerve cells which control the movement of muscles. "We hope that our findings can improve regenerative treatment of nerve injuries", explains Prof. Dr. Stefan Wiese from the Molecular Cell Biology study group.

Single molecule imaging movies of living cell membranes clarify enigma surrounding receptor molecule behaviors

Unprecedented single molecule imaging movies of living cell membranes, taken by a research team based at Kyoto University and the University of New Mexico, have clarified a decades-old enigma surrounding receptor molecule behaviors. The results, appearing in the latest issue of the Journal of Cell Biology, promise to open the door to new possibilities for drug development.

TREK1 activity offers a key target for fluoxetine and other antidepressant drugs

Using a unique and relatively simple cell-based fluorescent assay they developed, scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley have identified a means by which fluoxetine, the active ingredient in Prozac, suppresses the activity of the TREK1 potassium channel.

Research unmasks long sought stem cell origin of carcinoma

A constellation of different stem cell populations within our skin help it to cope with normal wear and tear. By constantly proliferating, the stem cells allow skin to replenish itself, allowing each cell to be replaced by a new one about once a month. But the normal cycle of division and death within one or more of these stem cell types can sometimes be derailed by genetic mishaps. Such events are believed to spawn carcinomas and other deadly skin cancers, which are the mostly frequently diagnosed cancers in the United States.

Generation of iPSCs can be enhanced by modulating miRNA action

Stem cells are ideal tools to understand disease and develop new treatments; however, they can be difficult to obtain in necessary quantities. In particular, generating induced pluripotent stem (iPS) cells can be an arduous task because reprogramming differentiated adult skin cells into iPS cells requires many steps and the efficiency is very low - researchers might end up with only a few iPS cells even if they started with a million skin cells.

Researchers grow arteries with elasticity of natural blood vessels outside the body

University of Pittsburgh researchers have grown arteries that exhibit the elasticity of natural blood vessels at the highest levels reported, a development that could overcome a major barrier to creating living-tissue replacements for damaged arteries, the team reports in the Proceedings of the National Academy of Sciences.

Scientists create 'reporter mouse' to close gap between kidney injury and diagnosis

The current check for kidney disease is a simple blood test for serum creatinine, but it can take longer than two days for this metabolite to accumulate to levels that are significant enough to indicate kidney damage - and by then it may be too late to intervene.

Scientists convert adult skin cells into cardiomyocytes using direct reprogramming strategy

Scripps Research Institute scientists have converted adult skin cells directly into beating heart cells efficiently without having to first go through the laborious process of generating embryonic-like stem cells. The powerful general technology platform could lead to new treatments for a range of diseases and injuries involving cell loss or damage, such as heart disease, Parkinson's, and Alzheimer's disease.

UMMS, Lundbeck announce research collaboration to develop targeted therapy for HD

The University of Massachusetts Medical School and Lundbeck Inc. today announced a research collaboration aimed at further development of a targeted therapy to slow or halt the progression of Huntington's disease.
