Stem cells may cause some forms of bone cancer

The researchers are the first to identify a population of cells with characteristics of adult and embryonic stem cells in cultures derived from biopsies of patients' bone tumors. They describe their findings in the medical journal Neoplasia.

Transport mechanisms for serotonin

Researchers at The Forsyth Institute have discovered that the transport mechanisms for serotonin - the chemical substance involved in transmitting signals between neurons, and which has a role in anxiety and mood disorders - play a key role in determining where organs are positioned in the body during embryonic development.

Recording the formation of a memory trace

Memory formation follows a dynamic pattern, allowing for retrieval from different areas of the brain, depending on when an organism needs to remember, said a researcher at Baylor College of Medicine.

Physicians slow to prescribe newer heart drugs

An analysis of the treatment received by more than 100,000 heart patients has shown that physicians' prescription practices for drugs proven effective for treating heart disease has shown steady improvement over the past three years, cardiologists at the Duke Clinical Research Institute (DCRI) have concluded.

Mesoblast recruits first patients for pilot clinical trials

Australia's adult stem cell company, Mesoblast Limited, today announced that several patients have now been formally recruited for its Pilot Clinical Trials.

Cancer cell resistance to chemotherapy drugs - mechanism discovered

Technion-Israel Institute of Technology researchers have discovered new mechanisms developed by cancer cells to become resistant to various chemotherapy drugs.

Intervention in immune regulation can prevent onset of type-1 diabetes

Some forms of diabetes could feasibly be prevented. Scientists at the German Research Centre for Biotechnology (GBF) in Braunschweig recently were able to do just that in experiments with mice.

Getting old? Slowing down? Blame inefficient mitochondria

In mitochondria, the fuel is oxidised and builds up a pressure of hydrogen ions (protons). These force through molecular turbines and enable the cell to generate ATP, an energy unit that can be used throughout the cell.

Cerebrospinal fluid analysis combined with brain scan predicts Alzheimer's

A combination of brain scanning with a new imaging agent and cerebrospinal fluid (CSF) analysis has left neuroscientists encouraged that they may finally be moving toward techniques for diagnosing Alzheimer's disease before its clinical symptoms become apparent.

Ack1 molecule stimulates the aggressive growth of prostate cancer

The molecule, Ack1, a member of the growth-promoting tyrosine kinase gene family, stimulates tumor formation in part by signaling prostate cells to rid themselves of a tumor-suppressor protein. Normally, this suppressor protein would inhibit rapid cell growth by signaling the cell to destroy itself.

Fibroblast research could lead to alternatives to implanted electronic pacemakers

In guinea pig experiments, Johns Hopkins scientists fused common connective tissue cells taken from lungs with heart muscle cells to create a safe and effective biological pacemaker whose cells can fire on their own and naturally regulate the muscle's rhythmic beat.

Alagebrium may prevent arterial aging in patients with systolic hypertension

A compound called alagebrium, which is very similar to another used in anti-wrinkle creams, may be useful in reducing the deleterious effects of arterial aging in the majority of elderly Americans with systolic hypertension, a new study from researchers at Johns Hopkins shows.

LEDGF protein controls the location of HIV integration in human cells

A human DNA-associated protein called LEDGF is the first such molecule found to control the location of HIV integration in human cells, according to researchers at the University of Pennsylvania School of Medicine.

Phenoxodiol - docetaxel combination for women with recurrent ovarian cancer

A clinical study of ovarian cancer initiated by investigators at Yale School of Medicine will combine the anti-cancer drug phenoxodiol with docetaxel for women with recurrent ovarian cancer.

Researchers link microRNA - miR 196 - to limb development

A tiny strand of molecules plays a role in how our arms and legs develop and grow - a finding that sheds light on perplexing bits of material once dismissed as genetic "junk," say scientists at the University of Florida and Harvard University.

Researchers move in on novel therapeutics to inhibit melanoma

Northwestern University researchers have developed a novel, three-dimensional model that allows scientists to observe how interacting with the microenvironment of metastatic melanoma cells induces normal skin cells to become similar to aggressive cancer cells that migrate and spread throughout the body.

Researchers detail mechanism of stroke

In the neural train wreck that is stroke, the cutoff of oxygen kills brain cells through a buildup of acid, as well as by overexciting receptors on the surface of brain cells.

Unexpected link between muscular dystrophy and muscle wasting associated with cancer

A new study provides important insight into the mechanisms of a muscle wasting disorder that interferes with treatment for cancer and has a negative impact on patient survival.

HRAS mutation analysis in Costello Syndrome

Gene mutations in the HRAS sequence are present in most patients affected with Costello syndrome, according to a new study in the American Journal of Medical Genetics. The mutations occurred de novo in patients, meaning, they were not observed in their parents' genes.
