Study defines complexity of underlying mutations responsible for pancreatic cancers

A large-scale study that defines the complexity of underlying mutations responsible for pancreatic cancers in more than 100 patients was published in Nature today.

New study finds bacteria cue single-celled choanoflagellates to form colonies

Bacteria have a bad rap as agents of disease, but scientists are increasingly discovering their many benefits, such as maintaining a healthy gut.

Novel approach to assemble the 'connectome' via genetic barcoding

A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October 23 in the open-access journal PLOS Biology.

Austrian researchers receive $7.4 million award to verify new breast cancer pathways

The innovator's award recognises Josef Penninger's work in identifying a key molecular pathway how hormone replacement therapies and contraceptive pills can lead to breast cancer. His team provided the first genetic proof that a protein called RANKL is the master regulator of bone loss, which has contributed to the development of a novel drug already approved for the treatment of osteoporosis and skeletal related events in multiple cancers.

Study looks at DNA sequences for receptors in T lymphocytes

Our immune system must be tremendously complex to respond to the unending assault of viruses, bacteria and cancerous cells. One of the mechanisms used by the immune system to cope with the huge variety of possible threats is to randomly combine DNA segments for the production of receptors on lymphocytes - a type of white blood cell.

New approach to prevention of breast cancer wins $7.4M award

A new approach to possible future prevention of breast cancer and slowing the spread of tumours has won Austrian researcher Josef Penninger, director of the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) in Vienna, a $7.4 million innovator's award to continue his research, from the USA's Congressionally Directed Medical Research Program.

Epigenetic alteration associated with increased risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

UCI, Brown work advances quest for novel treatments for inherited disorder

UC Irvine and Brown University researchers have created a new fruit fly model of inherited epilepsy that's providing insights into the mechanisms underlying temperature-dependent seizures while establishing a platform from which to develop therapies for these disorders.

AMP report provides overview of next generation sequencing technology

The Association for Molecular Pathology published the report of the Whole Genome Analysis Working Group of the AMP Clinical Practice Committee in the November 2012 issue of The Journal of Molecular Diagnostics.

Researchers identify crucial stage in the lifecycle of simple viruses

Researchers at the University of Leeds have identified a crucial stage in the lifecycle of simple viruses like polio and the common cold that could open a new front in the war on viral disease.

Research roundup: Financial impact of reducing surgical complications; Pay for performance to doctors, hospitals yields mixed results

The authors write: "We found that if a hospital's surgical inpatient volume is not growing, such a program results in negative cash flow. We also found that if a hospital's surgical volume is growing, and if the hospital can sufficiently reduce the average length-of-stay for surgical patients without complications, the cash flow could be positive. We recommend that hospitals with limited growth prospects that are nonetheless contemplating a surgical complication reduction program establish agreements with payers to share in any savings generated by the program."

New discovery could help revolutionize antibiotic treatment of bacteria

Three Simon Fraser University scientists are among six researchers who've made a discovery that could help revolutionize antibiotic treatment of deadly bacteria.

New study decodes complete epigenome of chronic lymphocytic leukemia

Researchers of the University of Oviedo have contributed to decipher the first epigenomes of chronic lymphocytic leukemia.

Salk findings on cold virus proteins may spur new cancer treatments

Cold viruses generally get a bad rap----which they've certainly earned----but new findings by a team of scientists at the Salk Institute for Biological Studies suggest that these viruses might also be a valuable ally in the fight against cancer.

Study finds novel function of non-protein coding RNA

While studying Parkinson's disease, an international research group made a discovery which can improve industrial protein synthesis for therapeutic use. They managed to understand a novel function of non-protein coding RNA: the protein synthesis activity of coding genes can be enhanced by the activity of the non-coding one called "antisense."

Researchers identify critical mechanisms of epigenetic cell programming

A team of researchers at the IRCM, supervised by Dr. Jacques Drouin, reprogrammed the identity of cells in the pituitary gland and identified critical mechanisms of epigenetic cell programming.

Brachyury variation may increase risk of chordoma

A genetic variation possessed by 40% of the population is associated with a five-fold increase in risk for developing chordoma, a cancer that strikes the bones of the skull and spine.

Mixing mitochondrial DNA bad for physiology

Mice with mitochondrial DNA from two sources have abnormal physiology and cognition, researchers report in Cell.

Accumulation of small genetic variations could increase risk of ASD

An increased risk of autism spectrum disorders (ASD) could result from an accumulation of many small, common genetic variations rather than large-effect, rare changes in the genetic code, according to a multicenter team led by researchers at the University of Pittsburgh School of Medicine.

NIH to accelerate development and application of single cell analysis across various fields

The National Institutes of Health plans to invest more than $90 million over five years, contingent upon the availability of funds, to accelerate the development and application of single cell analysis across a variety of fields.
