Survey Reveals Women Aren't Doing All They Can To Support Breast Health
A recent Yankelovich survey unveiled that although a large majority of women know there are simple steps they can take to support breast health, few women are taking the necessary actions. What"s more, 80 percent of the women surveyed have been personally affected by breast cancer or know someone who has been. To address this issue, One A Day Women"s Multivitamins is encouraging women to join a virtual march against breast cancer through the One A Day Women"s Take A Stand Campaign.

UVA Study Shows Early Success In Treating Deadly Brain Tumors
New research from the University of Virginia Health System shows that, when combined, two emerging medical technologies hold significant promise for treating the most deadly and devastating form of brain tumor, glioblastoma multiforme (GBM).

Rampant Helper Syndrome Methane-producing Molecule Can Also Repair DNA
Catalysts assist in chemical reactions without undergoing any alteration of their own. In the cells of living organisms, proteins perform this important function. They carry out the metabolism fundamental to all living processes. Proteins are instrumental in cellular respiration, they for instance reduce oxygen to water and oxidize food into carbon dioxide. This releases the energy that makes life possible at all.

Mapping Gene Expression With Gene Expression Atlas

Recently, researchers at the European Molecular Biology Laboratory"s European Bioinformatics Institute (EMBL-EBI) launched a new database, the Gene Expression Atlas, which allows scientists to search and compare gene expression data at unprecedented detail and scope. Observing how gene expression varies in different cell types, tissues and under disease conditions can help researchers understand gene function and to develop new drugs and therapies. Although most cells in an organism share the same genetic information, different cell types, for example skin and liver cells, have different properties and functions, largely because different genes are active in these cells. The Gene Expression Atlas is a new database that allows users to query gene expression under a range of biological conditions, including different cell types, developmental stages, physiological states, phenotypes and disease states. The key questions this new database can answer can be summarised as: 1. under which conditions is my particular gene of interest expressed? 2. which genes are expressed in a particular condition? For example, what genes are specifically active in kidney cells, or how does the expression of genes in leukemic blood differ compared to normal blood? Both questions can also be combined to focus on particular genes and their role in a specific disease, such as identifying members of the Wnt signalling pathway that are expressed in cancer. The Atlas collates data from over 1000 different independent studies, mainly microarray experiments, with more than 30,000 samples in total. The new database is the latest product of the EBI"s Microarray Informatics group and has its origins in the EBI"s ArrayExpress re. After a phase of development, the Atlas is ready to begin its own life as an independent major re. Misha Kapushesky, Atlas project leader at the EBI commented, "While the ArrayExpress Archive makes data from high throughput functional genomics assays available to experts, Gene Expression Atlas presents this information in a format accessible to any biologist. The Atlas takes data directly from the ArrayExpress Archive, which is then enriched by curation, re-annotation and statistical computations before the results are presented to the user in an easily accessible form." Notes: The Gene Expression Atlas has already found use in the pharmaceuticals industry as a valuable research platform. The re can be accessed from http://www.ebi.ac.uk/gxa and the Microarray Informatics group have produced an e-learning tutorial to guide users on how to get the most from the Atlas. This tutorial is freely available from the EBI"s e-learning portal at http://www.ebi.ac.uk/training/elearningcentral/.
