Brain circuit may permit scientists to eavesdrop on memory formation

... in learning and memory research that concerns the roles of two brain structures, the hippocampus, which is involved in memory formation, and the neocortex, which is associated with higher brain functions. "There are two key findings required to understand the present work," said Schuman. "First, lesions o...

New study will tackle three major killer diseases

...S) will increase our understanding of the relative roles of inheritance and the environment in causing these diseases, and will include a search for any genes that predispose strongly to illness. The volunteers taking part in the project will have the benefit of a health check and will also be contributing...

Toward a better understanding of taste and smell impairments

..., "Inflammatory processes are believed to play key roles in a variety of chronic diseases, including a number of forms of cancer, heart disease, and Alzheimer's disease. This research will contribute to the broader understanding of the impact of inflammatory mediators on cell function." The studie...

A new culprit in depression?

...sion research to go," says Evans. "Given the known roles of this FGF family in neural development and maintenance, it's not a huge leap to see how compromising the system could lead to changes in neural circuitry and contribute to mood disorders." "The bottom line is, the FGF system is less active in depr...

Structure of new DNA enzyme family member found

...protein began as a general kinase, playing lots of roles in the cell, he says. Eventually, it evolved and diverged into a group of different proteins, each of which could focus on a specialized task. Ealick's group now hopes to design a broad specificity riboside kinase as a laboratory tool for testing ant...

Conversion of flower organs into leaves

... functions. The ubiquitin pathway also plays major roles in many other cellular processes such as cell division, DNA repair, immune functions, and even gene expression, which determines what kind of cell a progenitor , or stem, cell becomes, making it a rich target for research on health, disease and aging...

No getting around RET

...ut GFRs have recently been suggested to play other roles as well. The individual functions of the RET and GFR subunits in these receptor complexes, which are important in developmental milieux from peripheral neurogenesis to the developing kidney, remains a thorny question complicated by the fact that GFR...

Study identifies molecular complex vital to creation of miRNAs

...ewed most broadly, they appear to play significant roles in controlling gene expression and development in many different settings. Now, a new study from researchers at The Wistar Institute identifies for the first time a molecular complex vital for the creation of miRNAs. This complex, dubbed the micropro...

Nobel Prize for Chemistry in 2004 The work of Professor Bouvier and his team is part of the leading edge of an international research movement, wh...

A 'repulsive' protein guides blood vessel development

...In their experiments, the researchers explored the roles of two proteins involved in vascular development. One of the molecules, Semaphorin 3E (Sema3E), is a member of a family of protein signals that guides the growth of nerve cells. The other protein, plexin-D1, is a receptor protein that nestles in the ...
