Drug rapamycin reverses mental retardation caused by tuberous sclerosis complex

UCLA researchers discovered that an FDA-approved drug reverses the brain dysfunction inflicted by a genetic disease called tuberous sclerosis complex (TSC). Because half of TSC patients also suffer from autism, the findings offer new hope for addressing learning disorders due to autism. Nature Medicine publishes the findings in its online June 22 edition.

New, previously unrecognized source of heart stem cells discovered

Researchers at Children's Hospital Boston are continuing to document the heart's earliest origins. Now, they have pinpointed a new, previously unrecognized group of stem cells that give rise to cardiomyocytes, or heart muscle cells. These stem cells, located in the surface of the heart, or epicardium, advance the hope of being able to regenerate injured heart tissue.

Study provides direct proof on how key protein promotes vascular disease

Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal Circulation.

Scientists identify a key regulator of DNA mutations

As a general rule, your DNA is not something you want rearranged. But there are exceptions - especially when it comes to fighting infections. Since the number of microbes in the world far surpasses the amount of human DNA dedicated to combat them, specialized cells in the immune system have adopted an ingenious, if potentially disastrous, strategy for making antibodies. These cells, called B lymphocytes, intentionally mutate their own DNA to ward off invaders they have never seen before.

Saving teeth by using periodontal ligament regeneration

Teeth may fall out as a result of inflammation and subsequent destruction of the tissues supporting the teeth. Dutch researcher Agnes Berendsen has investigated a possible solution to this problem. At the Academic Centre for Dentistry Amsterdam (ACTA), she has studied the regeneration of the periodontal ligament by use of tissue engineering.

Discovery of genes that regulate glucose levels

In an effort to understand how genes work, a collaborative study which includes the University of Southern California (USC) has identified a gene that regulates glucose levels. The results, which will be published in the July issue of the Journal of Clinical Investigation and is currently available online, may provide further understanding of the underlying causes of diabetes.

NGAL protein levels in simple urine test speed diagnosis of failing kidneys

Walk into any emergency department complaining of chest pain and you are likely to have blood drawn. Within hours it should be clear whether you've had a heart attack, based on enzyme levels in your blood and whether those levels reveal the tissue damage normally associated with a heart attack or other major cardiac event.

Personal genomes may lead to personalized vitamin supplements

As the cost of sequencing a single human genome drops rapidly, with one company predicting a price of $100 per person in five years, soon the only reason not to look at your "personal genome" will be fear of what bad news lies in your genes.

How advanced prostate cancer becomes resistant to androgen-deprivation therapy

For the past 70 years the treatment of choice for advanced, metastatic prostate cancer has been androgen-deprivation therapy. That is, the suppression of circulating testosterone - the hormone that fuels prostate-cancer growth - via surgical castration (orchiectomy) or medical castration with testosterone-blocking drugs. While such therapy buys time for patients, it is not a cure, as inevitably the cancer becomes resistant to the androgen deprivation and continues to grow.

Potential hypophosphatasia therapy discovered

Researchers at the Burnham Institute for Medical Research, led by José Luis Millán, Ph.D., have demonstrated in mice the first successful use of enzyme replacement therapy to prevent hypophosphatasia (HPP), a primary skeletal disease of genetic origin. This discovery lays the foundation for future clinical trials for HPP patients.
