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.

Study: Fluorescent probe may serve as useful tool in future surgeries to repair injured nerves

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered.

Researchers trace scent signals from nose to higher centers of mouse brain

Mice know fear. And they know to fear the scent of a predator. But how do their brains quickly figure out with a sniff that a cat is nearby?

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.

Immune protein exacerbates skin cancer due to sun exposure: Study

An unexpected immune protein exacerbates cancer due to sun exposure, report researchers in the January 27th issue of Nature. The study suggests that drugs blocking the protein might halt tumor growth in skin cancer patients.

Losartan improves effectiveness of nanotherapeutics against cancer

Low doses of an inexpensive, FDA-approved hypertension medication may improve the results of nanotherapeutic approaches to cancer treatment. In a report in the early edition of Proceedings of the National Academy of Sciences, Massachusetts General Hospital (MGH) investigators describe experiments showing that the generic drug losartan, by modifying the network of collagen fibers that characterizes most solid tumors, improved the effectiveness of two nanotherapeutics against several types of cancer.

Salk Institute uncovers presenilin's productive side

Mutant presenilin is infamous for its role in the most aggressive form of Alzheimer's disease-early-onset familial Alzheimer's-which can strike people as early as their 30s. In their latest study, researchers at the Salk Institute uncovered presenilin's productive side: It helps embryonic motor neurons navigate the maze of chemical cues that pull, push and hem them in on their way to their proper targets.

Time-lapse technique can show cellular-level changes within deep brain regions: Study

Changes within deep regions of the brain can now be visualized at the cellular level, based on research on mice, which was funded by the National Institutes of Health. Published Sunday in Nature Medicine, the study used a groundbreaking technique to explore cellular-level changes over a period of weeks within deep brain regions, providing a level of detail not possible with previously available methods.

UCLA imaging system could help reveal 'miscommunications' in autism, schizophrenia

Some disorders of the brain are obvious - the massive death of brain cells after a stroke, the explosion in the growth of cells that marks a tumor. Other disorders, such as autism, schizophrenia and mental retardation show no physical signs of damage and are believed to be caused by problems in how brain cells communicate with one another.
