Study examines genetic risk factors for Alzheimer's disease

... the most interesting gene being ‘GALP?which could affect the development of tangles within brain cells, a hallmark of Alzheimer’s disease. Professor Julie Williams, School of Medicine, who leads this project with Professor Micheal Owen said: “Whilst these genes are likely to make modest contributions to...

Stanford-led study closes in on genes that may predispose some people to severe depression

...h there are specific DNA sequence variations that affect one's risk of depression, then we would be able to understand what type of gene is it, what it does in the brain and by what mechanism it could make one more or less predisposed to depression." Knowing more about which genes are the major fac...

Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle

...sex hormone levels during women's menstrual cycles affect the responsiveness of their brains' reward circuitry, an imaging study at the National Institute of Mental Health (NIMH), a component of the National Institutes of Health (NIH), has revealed. While women were winning rewards, their circuitry was more...

Gut research yields new anti-cancer approach

...rences. While studying whether compounds known to affect PPARgamma could play a role in inflammatory bowel diseases, a team at the University of Rochester Medical Center found that medium-to-high doses of PPARgamma inhibitor killed colorectal cancer cell lines. Despite the compound's class name, the anti-c...

Study shows isolation of stem cells may lead to a treatment for hearing loss

...hese cochlear stem cells into the adult cochlea to affect hair cell replacement in the mouse, by extension, in humans?remarked Dr. Alagramam. In this paper, Drs. Miller and Alagramam offer further evidence for the existence of cochlear stem cells in the mouse cochlea by confirming the ability to form ‘st...

Population size and affluence have long been hypothesized to be primary drivers of environmental impact, however...

The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

...rophy (DMD). DMD is a genetic disease estimated to affect one in every 3,500 boys. Patients with DMD lack dystrophin, a protein that gives muscle cells structure. Using an animal model of the disease, his laboratory is using stem cells to deliver dystrophin to muscles. In this study, Dr. Huard’s team inj...

Scripps research study shows humans and plants share common regulatory pathway

...tle has been known about other proteins that might affect the protein’s activation. In contrast, a number of additional proteins have been linked to the activation pathways of the R protein in plants. "The NLR family has clear links to human disease," Ulevitch said. "Out of the more than 20 proteins in ...

New compound prevents alcoholic behavior, relapse in animals by blocking stress response

... to relapse under stress. Yet the compound did not affect their native curiosity or lower levels of drinking alcohol in rats that were not alcohol-dependent. In addition to alcoholism, the compound may prove to be useful in the treatment of depression or anxiety disorders, in which CRF levels can be espe...

'Guardian of the genome' protein found to underlie skin tanning

... skin to tan during sunlight exposure, it may also affect neuronal circuits," Fisher says. "These proteins may provide an explicit link between the regulation of tanning and of mood. It raises the question of whether p53-mediated induction of beta-endorphin is involved in sun-seeking behavior, which often i...

Although other studies have measured increases in the overall volume of the brain, Bearden said, this imaging method allowed the researchers to see exactly which brain regions were affected by lithium. "Bipolar patients wh...

This would put an early safeguard into the system that could be applied long before the drug was tested on animals or even humans. In addition, the electrical activity test could be used to monitor the effects of pollution ...
