Doing the math for membranes

Determining the mechanisms that shape biological membranes has long been a tricky business. Like a factory assembly line, eukaryotic cells are organized into membrane-bound, functional compartments called organelles.

Fruit flies provide new insights into a brain-damaging disease mucolipidosis type IV

Johns Hopkins researchers have used fruit flies to gain new insights into a brain-damaging disorder afflicting children.

Researchers shed new light on genetics of Parkinson's

A new study by Narendra et al. suggests that Parkin, the product of the Parkinson's disease-related gene Park2, prompts neuronal survival by clearing the cell of its damaged mitochondria.

More data released on key diabetes genes

One of the most reliable indicators to predict that a person will develop type 2 diabetes is the presence of insulin resistance.

New research reveals key steps in HIV's assault on the brain

Scientists have unraveled in unprecedented detail the cascade of events that go wrong in brain cells affected by HIV, a virus whose assault on the nervous system continues unabated despite antiviral medications that can keep the virus at bay for years in the rest of the body.

Scientists confirm a molecular clipping mechanism behind stem cell development

Stem cells don't just become a part of the liver or the brain in a flash; it takes a complex molecular choreography and requires that specific genes be switched on and off at specific times.

Proteomics provides clues to how tuberculosis thwarts the immune system

A link between the immune system and the self-cleaning system by which biological cells rid themselves of obsolete or toxic parts may one day yield new weapons in the fight against tuberculosis and other deadly infectious diseases.

Untapped potential of antidepressants for cancer

A comprehensive review of current scientific literature, published in the peer-reviewed journal ecancer, has suggested that antidepressants can help the human body fight cancer by boosting its own immune response, amongst other mechanisms.

Discovery of new function for an old enzyme in sialidosis

The lack of a single protein usually thought of as a run-of-the-mill enzyme that helps to recycle molecules in cells causes an incurable and often fatal disease of children, according to St. Jude Children's Research Hospital investigators.

Novel approach for treating mitochondrial disorders wins Kaye prize

A novel concept for the treatment of mitochondrial disorders using directed enzyme replacement therapy (DERT) has won for a Hebrew University of Jerusalem doctoral candidate one of this year's Kaye Innovation Awards. The awards were presented at this year's 71st meeting of the Hebrew University Board of Governors.

Breakthrough toxin delivery system could pave way for new antibiotic drugs

Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in monitoring the toxin-delivery system of highly pathogenic bacteria - an accomplishment that could help pave the way for new drugs that will be capable of neutralizing those germs.

Newly identified protein called BILBO1 fatal to Trypanosoma brucei

Trypanosoma brucei is a pathogen that causes epidemics of human and animal sleeping sickness in central and Southern Africa, a disease that is fatal if untreated. A new paper published this week in the open-access journal PLoS Biology investigates the formation of a trypanosome structure called the Flagellar Pocket (FP).

Epidermal growth factor receptor protects cancer cells from starving

A growth factor receptor found abundantly on the surface of cancer cells and long known to fuel cancer growth also protects tumor cells from starvation by a newly identified mechanism, researchers at The University of Texas M. D. Anderson Cancer Center report in the May 5 issue of Cancer Cell.

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection

As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease.

From algae to parasites: new 'missing link' species found in Sydney Harbour

It's not often that brown algae is considered exciting or revolutionary, but Associate Professor Dee Carter from the School of Molecular and Microbial Biosciences at the University of Sydney and her former PhD student, Robert Moore, have found a new species of single-celled brown algae that is an evolutionary missing link.

Scientists identify key protein in cell's 'self-eating' function

Molecular biologists at the University of California, San Diego have found one piece of the complex puzzle of autophagy, the process of "self-eating" performed by all eukaryotic cells - cells with a nucleus - to keep themselves healthy.

New chemical tool kit manipulates mitochondria, reveals insights into drug toxicity

Why do nearly 1 million people taking cholesterol-lowering statins often experience muscle cramps? Why is it that in the rare case when a diabetic takes medication for intestinal worms, his glucose levels improve? Is there any scientific basis for the purported health effects of green tea?

Coral alga may hold key to malaria prevention

A brown alga discovered in Sydney harbour by Sydney University scientists could provide the key to treating diseases that disable and kill millions each year

21 Feb 2008

Researchers spearhead key genome initiative

The complete collection of genes - the genome - of a moss has been sequenced, providing scientists an important evolutionary link between single-celled algae and flowering plants.

Researchers find evidence of mature heart cell potential in embryonic stem cells

In a new study, UC Davis researchers report the first functional evidence that heart cells derived from human embryonic stem cells exhibit one of the most critical properties of mature adult heart cells, an important biological process called excitation-contraction coupling.
