Researchers from the Institute of Psychiatry (IoP), King's College London, have identified numerous novel regions of the genome where the chemical modifications involved in controlling gene expression are influenced by either genetic variation or the parental origin of that particular stretch of DNA. This contradicts previous assumptions that epigenetic signals are generally equal across both copies of a given region of the genome, except at a small number of known imprinted genes. Sequencing...

Gastric cancer, one of the most common types of cancer, is associated with high mortality rates. In the last decades, a decrease in the worldwide incidence has been observed with some changes in the therapeutic and diagnostic options. However, the prognosis for this disease still remains poor, mainly when the diagnosis is performed at advanced stages. The therapy most effective is still surgical resection and in a significant number of cases, especially in the advanced stage, it is only...

Billions of data points provide big picture of 'human epigenome' during critical developmental window Scientists at The Scripps Research Institute and The Genome Institute of Singapore (GIS) led an international effort to build a map that shows in detail how the human genome is modified during embryonic development. This detailed mapping is a significant move towards the success of targeted differentiation of stem cells into specific organs, which is a crucial consideration for stem cell...

Increasing numbers of research studies clearly demonstrate that genetics alone cannot explain the diversity of living organisms, reports Genetic Engineering & Biotechnology News (GEN). Also driving the development of such complexity is epigenetics, and the February 1 issue of GEN contains three articles that illustrate the growing recognition of the importance of this emerging field of study. "Scientists have shown that non-DNA-sequence-changing epigenetic phenomena such as histone...

Scientists have found what they believe is the "missing link" between heart failure, our genes and our environment. The study could open up completely new ways of managing and treating heart disease. The Cambridge team compared heart tissue from two groups "“ patients with end-stage heart failure and those with healthy hearts. The diseased tissue came from men who had undergone heart transplants at Papworth Hospital, Cambridge, and the healthy hearts from age-matched victims of road...

U of Minnesota researcher leads study Researchers at the University of Minnesota have discovered a molecular security system in human cells that deactivates and degrades foreign DNA. This discovery could open the door to major improvements in genetic engineering and gene therapy technologies. Led by Reuben Harris, associate professor of biochemistry, molecular biology and biophysics in the College of Biological Sciences, the report's findings was published online by Nature Structural and...

Epigenetic diagnosis and therapies, a new strategy for treating cancer In recent years it has been appreciated that there are additional chemical codes in addition to DNA sequence that control the behavior of normal and malignant cells. These additional codes are called "epi"genetic since they are contained outside of the DNA sequence. The investigators have concluded that much of the inter-patient difference in leukemia cell behavior is dependent on a patient's specific epigenetic...

The DNA contained within each of our cells is exactly the same, yet different types of cells "“ skin cells, heart cells, brain cells "“ perform very different functions. The ultimate fate of these cells is encoded not just in the DNA, but in a specific pattern of chemical modifications that overlay the DNA structure. These modifications, or epigenetic markers as they are called, are stably carried in our genomes -- except for at times when the cells change their fate, such as what...
