Reduction in myelin production may also play a role in development of mental illness

Reduced production of myelin, a type of protective nerve fiber that is lost in diseases like multiple sclerosis, may also play a role in the development of mental illness, according to researchers at the Graduate School of Biomedical Sciences at Mount Sinai School of Medicine. The study is published in the journal Nature Neuroscience.

Advances in genomic techniques help understand cancer at cellular and molecular level

Cancer is a complex disease and only thanks to advances in genomic techniques have researchers begun to understand, at a cellular and molecular level, the mechanisms which are disrupted in cancer cells. This knowledge is a key prerequisite for developing effective treatment strategies.

Study provides new insight into human cognitive function and risk for neurological diseases

Short snippets of DNA found in human brain tissue provide new insight into human cognitive function and risk for developing certain neurological diseases, according to researchers from the Departments of Psychiatry and Neuroscience at Mount Sinai School of Medicine. The findings are published in the November 20th issue of PLoS Biology.

Dysregulation of CISTR-ACT causes brachydactyly type E

The patients have single short fingers (metacarpals) and toes (metatarsals) and can be restricted in growth due to a shortened skeleton. This hereditary disease is called brachydactyly type E (Greek for short fingers).

Researchers identify genes linked to serous endometrial cancer

Researchers have identified several genes that are linked to one of the most lethal forms of uterine cancer, serous endometrial cancer.

Idea of nuclear reprogramming holds promise for repairing damaged tissue

The idea of taking a mature cell and removing its identity (nuclear reprogramming) so that it can then become any kind of cell, holds great promise for repairing damaged tissue or replacing bone marrow after chemotherapy.

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.

Chromosome 3p21.1 locus contains common genetic risk for bipolar disorder

One of the biggest challenges in psychiatric genetics has been to replicate findings across large studies. Scientists at King's College London, Institute of Psychiatry have now performed one of the largest ever genetic replication studies of bipolar affective disorder, with 28,000 subjects recruited from 36 different research centers. Their findings provide compelling evidence that the chromosome 3p21.1 locus contains a common genetic risk for bipolar disorder, the PBRM1 gene.

Mouse genome consists of 10-nm chromatin fibres

Scientists in Canada and the United States have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibres. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibres but did not find evidence for the wider 30-nm fibres that were previously thought to be important components of the DNA architecture.

People with SIRT1 genetic variation more likely to develop vibration-induced white finger disease

Vibration-induced white finger disease (VWF) is caused by continued use of vibrating hand held machinery (high frequency vibration >50 Hz), and affects tens of thousands of people. New research published in BioMed Central's open access journal Clinical Epigenetics finds that people with a genetic polymorphism (A2191G) in sirtuin1 (SIRT1), a protein involved in the regulation of endothelial NOS (eNOS), are more likely to suffer from vibration-induced white finger disease.

Study finds new regulator for heart formation

A new regulator for heart formation has been discovered by studying how embryonic stem cells adjust the packaging of their DNA. This approach to finding genetic regulators, the scientists say, may have the power to provide insight into the development of any tissue in the body - liver, brain, blood and so on.

Hundreds of new genes are involved in function and development of T-cells

A research team led by investigators at New York University and NYU School of Medicine has determined how cells that cause inflammatory ailments, such as Crohn's disease, multiple sclerosis, and arthritis, differentiate from stem cells and ultimately affect the clinical outcome of these diseases.

Researchers obtain first detailed and complete picture of PRC2 protein

The first detailed and complete picture of a protein complex that is tied to human birth defects as well as the progression of many forms of cancer has been obtained by an international team of researchers led by scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab).

SOX2 gene potential therapeutic target for SCLC

Expression of the Sry-related HMG box 2 gene is higher in small-celllung cancer tissue samples than in non-cancerous lung tissue samples, according to findings from a genetic study.

Sifting through the junk with ENCODE

The first large-scale results from the ENCylopedia Of DNA Elements Consortium have shed light on possible functions of large areas of the genome previously thought of as “junk DNA.”

Parental methylated histones not transferred to daughter DNA

It's widely accepted that molecular mechanisms mediating epigenetics include DNA methylation and histone modifications, but a team from Thomas Jefferson University has evidence to the contrary regarding the role of histone modifications.

MOZ protein could explain variations in severity of DiGeorge syndrome

The discovery of a 'switch' that modifies a gene known to be essential for normal heart development could explain variations in the severity of birth defects in children with DiGeorge syndrome.

Mof protein plays a key role in epigenetics of stem cells

How do stem cells preserve their ability to become any type of cell in the body? And how do they "decide" to give up that magical state and start specializing? If researchers could answer these questions, our ability to harness stem cells to treat disease could explode. Now, a University of Michigan Medical School team has published a key discovery that could help that goal become reality.
