A novel and universal method for microRNA data analysis

Our understanding of the importance of microRNAs in regulating gene expression is expanding, and with it our requirement for robust methods to measure their expression levels. Now a new method published in BioMed Central's open access journal Genome Biology helps researchers to better understand the delicate interplay between differences in microRNA expression levels and their target genes.

Discovery of key gene in deadly inflammatory breast cancer

Aggressive, deadly and often misdiagnosed, inflammatory breast cancer (IBC) is the most lethal form of primary breast cancer, often striking women in their prime and causing death within 18 to 24 months.

Scientists launch Gene Expression Atlas

Today, researchers at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) launch 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.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Don't stress when the going gets tough - you'll go gray!

A study by Japanese researchers has revealed that a certain kind of stress damages the hair - they say "genotoxic stress" damages DNA by depleting the melanocyte stem cells (MSCs) within hair follicles that are responsible for making the pigment-producing cells.

Global Post articles examine Malaria worldwide

Global Post examines the quest for an effective vaccine to fight malaria. According to Global Post, "epidemiologists are pinning their hopes on a malaria vaccine" because "[k]illing mosquitoes, or avoiding bites, is an imprecise solution to malaria."

Scientists create simple chemical system that mimics DNA

A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

Researcher looks for link between gene and pregnancy weight gain

Even before last week’s release of revised pregnancy weight-gain guidelines, a researcher at the University of Rochester School of Nursing was studying why certain women gain more pounds than others and searching for ways to help them maintain healthy weights.

51 genes predict breast cancer survival

It may be possible in the future to use a specimen from the tumour to determine which patients with breast cancer have a good chance of overcoming the disease, and which patients should be given more intensive treatments.

Researchers estimate risk of transmission of Huntington's disease to offspring among male carriers

Researchers from Boston University School of Medicine (BUSM) have quantified the probability of a male who carries a "high normal" variant of the Huntington's Disease (HD) gene having a child who develops the disease. Although thought to be a very rare event, the probability has never been estimated using current information and disease guidelines. The findings, appear on-line in the American Journal of Medical Genetics, may be useful during prenatal genetic counseling.
