New Oncogene for Brain Cancer

...he glial cells which normally support and nourish neurons -- that are highly resistant to treatment. This makes IGFBP2 an important candidate for development of targeted therapy to treat gliomas, Zhang says. Gliomas kill about 13,000 people in the United States annually. The possibilities are not limite...

Insight Into Neural Stem Cells Has Implications For Designing Therapies

...godendrocytes and neurons. Their role in producing neurons is of particular interest to scientists because neurons orchestrate brain functions -- thought, feeling and movement. If scientists could figure out how to...

Scientists Find Single Circuit Channeling Depression in Rats

...igh-resolution cameras to record activity in brain neurons in real time. According to Deisseroth, rat brains show similar depression symptoms to human ones and react to anti-depression medicines in the same way. The testing showed that an alteration in electrical activity flow through the brain could be ...

Stem Cells Research in Parkinsons Disease

...ipients a significant amount of dopamine-producing neurons that were not derived from stem cells. The results suggest that stem cells may actually trigger the brains own self-repair mechanisms by pumping out molecules that boost nerve survival and blood vessel development and decrease neural degeneration. ...

Eap1 in the Brain Regulates the Female Reproductive Cycle

...female reproductive cycle are events controlled by neurons in the hypothalamus that secrete gonadotropin-releasing hormone (GnRH). How signaling to these neurons is controlled remains unclear. In a study appearing online on July 12 in advance of publication in...

Bak Protein Sets Stressed Cells on Suicide Path

...ctured mitochondria. Looking at kidney cells and neurons in a Bak deficient mouse, they also showed that Bak and Bax need each other to successfully spawn cell suicide. "If you have Bak but not Bax, the mitochondria still fragment but they don't die; if you have Bax but not Bak, you still have puncture...

Sensible Diet, Exercise and Weight Control Increases Longevity

... Because reducing insulin-like signalling in the neurons of roundworms and fruitflies extends their lifespan, the researchers decided to examine what would happen when they knocked out one or both copies of the Irs2 gene only in the brains of mice. Mice lacking one copy of the Irs2 gene in brain cells a...
