Gene linked with mental illness shapes brain region, researchers find

... brief influence on the target neurons. Drugs that prevent this re-uptake, such as Prozac, are frequently used to treat patients with depression. The serotonin transporter gene has two forms, or variants: short, or SERT-s, and long, SERT-l. A person can have two copies of the short gene, one copy each of...

...es to reliably identify and treat cases, let alone prevent these diseases," he says. "In up to 95 per cent of cases, the root causes of vascular diseases are still unknown. So clinicians have to rely on 'lifestyle' indicators and 'risk factors' such as high blood pressure and high cholesterol. "However, no...

...ollistatin. Basically, what follistatin does is to prevent myostatin from working, says Dr. Sartorelli. When his group treated the cells with deacetylase inhibitors, they saw that the cells became large and that follistatin was overexpressed. However, when the group treated the cells with the inhibitors and ...

An AIDS-related virus tricks cells to become tumors, new Penn study finds

...ion. Tumor suppressors, as their name implies, prevent or limit the growth of tumors in numerous ways. One way the tumor suppressors p53 and VHL work is to mark a key protein that controls the blood supply in a tumor mass. Once marked, this protein called hypoxia-induced factor 1a (HIF-1a) is degraded th...

Researchers identify a key regulator for skin stem cells

By turning on a single gene, researchers can prevent skin stem cells from maturing into the three types of adult skin cells -- epidermal, sebaceous and hair cells. They say this finding could have important implications for scientists trying to grow stem cells in the lab, for both research and potentia...
