Scientists discover origin of Barrett's esophagus

Dr Frank McKeon, Senior Group Leader of the Stem Cell and Developmental Biology at A*STAR's Genome Institute of Singapore, and Principal Investigator Dr Wa Xian at A*STAR's Institute of Medical Biology, together with their counterparts from the Harvard Medical School, the Brigham and Women's Hospital in Boston, and the National University of Singapore, have made the striking finding that Barrett's esophagus work, published online in the journal Cell on 24 June 2011, is essential to developing therapeutics for esophageal cancer.

Chaos in biochemical alterations of cancer cells

Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a Johns Hopkins team says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.

Study links genetic variants in MHC region with risk of lupus in African American women

Researchers from Boston University's Slone Epidemiology Center have found four new genetic variants in the major histocompatibility complex (MHC) that confer a higher risk of systemic lupus erythemathosus in African American women.

23andMe study discovers two novel gentic associations with Parkinson's

Today 23andMe, an industry leader in personal genetics, announced the discovery of two significant, novel genetic associations with Parkinson's disease (PD) and provided new evidence that there is a substantial genetic component remaining to be discovered for Parkinson's.

A*STAR-CSI scientists discover how body uses single communication system to decide fate of stem cells

Scientists from the Genome Institute of Singapore (GIS), an institute of the Agency for Science, Technology and Research (A*STAR), in collaboration with the Cancer Science Institute of Singapore (CSI), have discovered how the body uses a single communication system to decide the fate of stem cells.

Epilepsy may arise from complex mixture of altered ion channels

Imagine two flat screen televisions tuned to the same channel and sitting side-by-side. From a distance, their pictures are virtually the same, however up close, you can see subtle variations in the pixels - one blurred here, another dropped out there.

Stresses can change gene expression without DNA sequence change

None of us are strangers to stress of various kinds. It turns out the effects of all those stresses can change the fate of future generation, influencing our very DNA without any change to the underlying sequence of As, Gs, Ts and Cs. Now, researchers reporting in the June 24th issue of Cell, a Cell Press publication, have new evidence that helps to explain just how these epigenetic changes really happen.

RIKEN researchers reveal mechanism for stress-induced epigenetic change

Researchers at RIKEN have uncovered a mechanism by which the effects of stress in the fly species Drosophila are inherited epigenetically over many generations through changes to the structure of chromatin, the material that makes up the cell nucleus.

Study traces precursor of deadly esophageal cancers to leftover embryonic cells

The ultimate source of some cancers is embryonic cells. Research published in the June 24th Cell, a Cell Press publication, traces the precursor of deadly esophageal cancers to leftover embryonic cells found in all adults.

New VAAST software tool can identify disease-causing mutations in rare genetic disorders

Harnessing the new generation of rapid, highly accurate gene-sequencing techniques, a research team has identified the disease-causing mutation in a newly characterized rare genetic disease, by analyzing DNA from just a few individuals.

CBMi creates iPad app for exploring human genomic information

Navigating the human genome with software that you can view on an iPad® sounds pretty impressive, until perhaps you reflect that nature has already encoded trillions of copies of this in your chromosomes. Then again, printing that data using ink and paper would produce a mind-staggering pile of pages—so viewing it on an iPad® may be impressive after all.

Researchers discover new mechanism for origin of Barrett's esophagus

Researchers have discovered a new mechanism for the origin of Barrett's esophagus, an intestine-like growth in the esophagus that is triggered by chronic acid reflux and often progresses to esophageal cancer.
