NIH researchers discover protein that appears to regulate bone mass loss, the cause of osteoporosis
03-05-2007 · EurekAlert!
An estimated ten million Americans suffer from osteoporosis, and another 34 million Americans are at risk of developing the disease. The basic mechanism behind osteoporosis involves an imbalance between bone mineral formation and loss, but the detailed biological processes that lead to this imbalance are not completely understood. Now researchers at NIAID and colleagues are reporting new insights into the biology of bone loss based on a study of 14 people with a rare genetic disorder called X-linked Hyper IgM Syndrome.

Quality control mechanism tags defective sperm cells inside the body
01-23-2008 · EurekAlert!
Defective sperm cells do not pass through the body unnoticed. A new University of Missouri study provides evidence that the body recognizes and tags defective sperm cells while they undergo maturation in the epididymis, a sperm storage gland attached to the testis. According to researchers, only the best sperm that have the highest chance of succeeding in fertilization will survive the production process without a "tag."

Molecular 'trip switch' shuts down inflammatory response
12-13-2007 · EurekAlert!
Like a circuit breaker that prevents electrical wiring from overheating and bringing down the house, a tiny family of three molecules stops the immune system from mounting an out-of-control, destructive inflammatory response against invading pathogens, researchers at the Salk Institute for Biological Studies have found.

Patterns on tropical marine mollusk shell mirror gene expression patterns
11-21-2006 · EurekAlert!
Scientists have identified a group of genes that control the formation of shapes and color patterns on the shell of the tropical marine mollusk referred to as "abalone." A study published today in the open access journal BMC Biology reveals that the shape and color patterns on the shell of the mollusc mirror the localised expression of specific genes in the mantle, a layer of skin situated just below the shell.

New mechanism for nutrient uptake discovered
02-11-2007 · EurekAlert!
Biologists at the Carnegie Institution's Department of Plant Biology have discovered a new way that plant cells govern nutrient regulation—neighboring pore-like structures at the cell’s surface physically interact to control the uptake of a vital nutrient, nitrogen. It is the first time scientists have found that the interaction of neighboring molecules is essential to this regulation. The discovery has widespread potential -- from understanding human diseases, such as kidney function, to engineering better crops.

Major breakthrough in the mechanism of myelin formation
11-02-2006 · EurekAlert!
The group of Dr. Michel Cayouette, researcher at Institut de recherches cliniques de Montréal (IRCM), and Dr. Jonah Chan, collaborator at the University of Southern California, will publish in the next issue of the prestigious scientific journal Science the results of their study that could have a major impact on the treatment of diseases such as multiple sclerosis, and preipheral neuropathies.

Aging gracefully requires taking out the trash
12-14-2007 · EurekAlert!
Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration. In an upcoming issue of Autophagy, scientists at the Salk Institute for Biological Studies report for the first time that the opposite is true as well: Boosting autophagy in the nervous system of fruit flies prevented the age-dependent accumulation of cellular damage in neurons and promoted longevity.
