DNA Methylation News and Research

RSS

DNA methylation is a type of chemical modification of DNA that can be inherited and subsequently removed without changing the original DNA sequence. As such, it is part of the epigenetic code and is also the most well characterized epigenetic mechanism.

Exact Sciences to demonstrate methylation specific technology at AACC annual meeting

Exact Sciences Corp. today announced that data being presented this afternoon at the annual meeting of the American Association of Clinical Chemistry demonstrates that its methylation specific technology, using a combination of DNA methylation markers, detected 100 percent of colorectal cancers and precancers at a specificity cutoff of 100 percent in a preliminary study with colorectal tissue.

Researchers reveal findings on restricted lineage of iPS cells

Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem cells for basic research and cell replacement therapies, according to researchers at Children's Hospital Boston, John Hopkins University and their colleagues

Keck School of Medicine receives grant for research on biomarker impact on breast cancer screening

Researchers at the Keck School of Medicine of the University of Southern California (USC) will test whether a set of blood-based biomarkers can assist mammography in the early detection of breast cancer with a $180,000 grant announced today from Susan G. Komen for the Cure®. The grant will fund research into whether specific biomarkers, or minute substances in the blood, can effectively distinguish breast cancer patients from their healthy counterparts and whether an inexpensive, less invasive screening strategy can be developed based on this approach.

Epigentek develops new approach for identification of "sixth DNA base" 5-hmC

Research experts in the epigenetic field from Epigentek have developed a new, breakthrough approach for the identification of the "sixth DNA base," 5-hydroxymethylcytosine (5-hmC). This technology is based on a high throughput, strip-well format and is also incorporated into the first commercially available product, the MethylFlash(TM) Hydroxymethylated DNA Quantification Kit, for rapidly quantifying hydroxymethylated DNA.

Form of epigenetics may play role in pulmonary arterial hypertension: Researchers

A rare but fatal disease of blood vessels in the lung may be caused in part by aberrant silencing of genes rather than genetic mutation, new research reports. Pulmonary arterial hypertension, a syndrome characterized by gradual blockage of blood vessels in the lungs, has been linked to genetic causes in a small percentage of patients. But University of Chicago researchers have now found that a form of epigenetics - the modification of gene expression - causes the disease in an animal model and could contribute to the disease in humans.

WRNp controls key step in pluripotent stem cell differentiation: Study

A gene shown to play a role in the aging process appears to play a role in the regulation of the differentiation of embryonic stem cells, according to researchers from the Center for Stem Cell Biology and Regenerative Medicine and the Department of Medicine at Thomas Jefferson University.

Researchers discover relationship between DNA methylation and positioning of nucleosomes

A previously unknown pattern in DNA methylation - an event that affects cell function by altering gene expression - has been uncovered for the first time by stem cell researchers at UCLA, a finding that could have implications in preventing some cancers and correcting defects in human stem cell lines.

Imprinted genes may be the root cause of gender specific diseases, says study

Pregnancy places competing demands on a mother's physiology: Her body wants to produce a strong healthy baby but not at the expense of her own health. Some of the genes that she passes on to her child therefore try to protect her own body from excessive demands from her child.

NIH awards UIC $10M grant to study health disparities among underserved, minority women with breast cancer

A $9.6 million grant from the National Institutes of Health has been awarded to the University of Illinois at Chicago to study access to care and health disparities among underserved and minority women with breast cancer in Chicago.

MMRC Multiple Myeloma Genomics Initiative presented at AACR 2010

An analysis of 38 myeloma tumor genomes surveyed through extensive next-generation sequencing by the Broad Institute has revealed intriguing recurrent mutations that point to important cellular pathways which contribute to multiple myeloma. These data were revealed during an oral presentation entitled "First Impressions of the Multiple Myeloma Genome" by Todd R. Golub, MD, Director of the Cancer Program at the Eli and Edythe L. Broad Institute.

Ghent University signs agreement to use Roche's LightCycler 1536 Instrument for cancer research

Roche and Ghent University (Belgium) have signed an agreement for the use of Roche's LightCycler® 1536 Instrument in various cancer research projects in Ghent. Studies include multigene expression signature profiling on cancer research samples and, digital PCR for sensitive detection of mutant cancer cells in a background of normal cells.

DNA modification can define early onset glioblastoma

A class of brain tumor that tends to emerge in younger patients but is less aggressive than others can be identified by examining DNA methylation of a specific set of genes, scientists at The University of Texas M. D. Anderson Cancer Center and colleagues with The Cancer Genome Atlas report today online at Cancer Cell.

Research may provide better clinical outcomes for patients with aggressive type of brain cancer

A study conducted by a collaborative team led by researchers from the University of Southern California (USC) may lead to better insight into the clinical outcome for some patients with a particularly aggressive type of brain cancer. The research may also provide a framework for development of targeted drug treatments.

UBC doctoral candidate discovers a mechanism for silencing retroviruses

A University of British Columbia doctoral candidate has discovered a previously unknown mechanism for silencing retroviruses, segments of genetic material that can lead to fatal mutations in a cell's DNA.

Mutations in MeCP2 cause autism spectrum disorder Rett Syndrome

A paper published online today in Molecular Cell proposes that Methyl CpG binding protein 2 (MeCP2) impacts the entire genome in neurons, rather than acting as a regulator of specific genes. Mutations in MeCP2 cause the autism spectrum disorder Rett Syndrome as well as some cases of neuropsychiatric problems including autism, schizophrenia and learning disabilities.

Children born through assisted reproduction at greater risk of obesity and type 2 diabetes related defects

More than three million children have been born as a result of assisted reproductive technologies since the birth of the first "test tube baby" in 1978. While the majority of these children are healthy and normal, as a group they are at greater risk of certain kinds of birth defects and being low birth weight, which is associated with obesity, hypertension and type 2 diabetes later in life.

Allele-specific DNA methylation a widespread phenomenon, reveals IoP study

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.
