Geniom RT Analyzer provides accurate diagnosis of multiple sclerosis and lung cancer disorders

Data published in BMC Cancer and PLoS ONE show that microRNA (miRNA) biomarkers provide reliable and highly differentiated diagnosis from blood samples for lung cancer and multiple sclerosis.

New mouse models resembles human ALS; may provide important tool for screening new drugs

A new mouse model of amyotrophic lateral sclerosis (ALS) closely resembles humans with the paralyzing disorder, researchers at Washington University School of Medicine in St. Louis report.

NCI selects Integral Molecular to map epitopes for monoclonal antibodies

Integral Molecular, Inc. has been selected by the National Cancer Institute (NCI) to map epitopes for monoclonal antibodies directed against cancer biomarkers. Protein targets of interest to the Clinical Cancer Proteomics community will be analyzed using Shotgun Mutagenesis Mapping technology to identify amino acids that are essential for antibody binding, allowing the discovery and characterization of cancer-specific biomarkers.

Changes in mtDNA can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria - popularly known as the cells' power plants - become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.

Unstable proteins can cause premature ageing

The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients.

Discovery shows that different parts of chromosomes can have very different evolutionary histories

A new study reveals that - contrary to decades of evolutionary thought - chromosome regions that are prone to breakage when new species are formed are a rich source of genetic variation.

Research shows how p53 mutations link to high-grade breast cancer, poor outcomes

In what is believed to be the largest study of its kind in the US, researchers have found that almost 26 percent of women studied who have breast cancer have mutations in a gene important in controlling cell growth and death, and that patients with mutations in this gene - known as p53 - had poorer outcomes including a significantly increased risk of death from the cancer.

Tiny genetic change keeps nicotine from binding to muscle cells

A tiny genetic mutation is the key to understanding why nicotine--which binds to brain receptors with such addictive potency--is virtually powerless in muscle cells that are studded with the same type of receptor.

How loss or mutation of LMNA gene causes Emery-Dreifuss muscular dystrophy

Mutations in the nuclear intermediate filament lamin A/C (LMNA) gene are associated with Emery-Dreifuss muscular dystrophy, but cause the disease by unknown mechanisms.

Researcher develops method for early detection of leukemia relapse

Researchers at the Fred Hutchinson Cancer Research Center have developed a method that allows for the early detection of a common mechanism of resistance on drug treatment for chronic myeloid leukemia.

Potential new neuronal tumor suppressor

In a G&D paper published online ahead of its April 1 print publication date, Dr. William Kaelin (Dana Farber Cancer Institute) and colleagues identify a potential new neuronal tumor suppressor.

Genomatix integrates genome-wide open chromatin from next generation sequencing

Genomatix Software GmbH, a Systems Biology company focussed on high quality annotation and the understanding of gene regulation, has begun showcasing its abilities in the analysis of data generated by Next Generation Sequencing (NGS) technology.

Losses of long-established genes contribute to human evolution

While it is well understood that the evolution of new genes leads to adaptations that help species survive, gene loss may also afford a selective advantage.

Genetic evidence that human evolution is speeding up

Researchers discovered genetic evidence that human evolution is speeding up – and has not halted or proceeded at a constant rate, as had been thought – indicating that humans on different continents are becoming increasingly different.

Genetic differences point to ethnic and racial disparities in colorectal cancer risk

Risk of developing colorectal cancer is known to differ across ethnic and racial groups, and now an analysis of 26 studies, involving over 25,000 participants shows that some of these disparities might be explained by distinct patterns of genetic inheritance.

New explanation for how regulatory networks of genes evolved

When ancient retroviruses slipped bits of their DNA into the primate genome millions of years ago, they successfully preserved their own genetic legacy.

New view of what causes greatest genetic variability among individuals

A study by Yale researchers offers a new view of what causes the greatest genetic variability among individuals - suggesting that it is due less to single point mutations than to the presence of structural changes that cause extended segments of the human genome to be missing, rearranged, or present in extra copies.

Smallpox evolved earlier than believed

Smallpox is older than thought, according to results of a new technique reported in the Sept. 24 issue of the Proceedings of the National Academy of Sciences by researchers from Lawrence Livermore National Laboratory and the Centers for Disease Control (CDC).

Androstenone determines whether male body odor smells pleasant

New research from Rockefeller University, performed in collaboration with scientists at Duke University in North Carolina, reveals for the first time that this extreme variability in peopl's perception of androstenone is due in large part to genetic variations in a single odorant receptor called OR7D4.
