Scientists discover recurring pattern of more than 13,000 epigenetic alterations in young tumours

Tumourigenesis is driven by genetic alterations and by changes in the epigenome, for instance by the addition of methyl groups to cytosine bases in the DNA. A deeper understanding of the interaction between the genetic and epigenetic mechanisms is critical for the selection of tumour biomarkers and for the future development of therapies. Human tumour specimens and cell lines however contain a plethora of genetic and epigenetic changes, which complicate data analysis.

Basis of antidepressant drugs and electroconvulsive therapy found

Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy. Results of their experiments explain how these therapies likely work to relieve depression by stimulating stem cells in the brain to grow and mature.

Accumulation of passenger mutations can slow or even halt tumor growth

A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression.

Scientists track evolution of antibiotic resistance using automated device

With the discovery of antibiotics, medicine acquired power on a scale never before possible to protect health, save lives, and reduce suffering caused by certain bacteria. But the power of antibiotics is now under siege because some virulent infections no longer respond to antibiotic drugs.

Weill Cornell and NewYork-Presbyterian create pioneering Institute for Precision Medicine

Recognizing that medicine is not "one size fits all," Weill Cornell Medical College and NewYork-Presbyterian Hospital have created the pioneering Institute for Precision Medicine at Weill Cornell and NewYork-Presbyterian/Weill Cornell Medical Center. This new, cutting-edge translational medicine research hub will explore the new frontier of precision medicine, offering optimal targeted, individualized treatment based on each patient's genetic profile.

Study expands and deepens biological and genetic links between CVD and schizophrenia

A new study, to be published in the Feb. 7, 2013 issue of the American Journal of Human Genetics, expands and deepens the biological and genetic links between cardiovascular disease and schizophrenia. Cardiovascular disease (CVD) is the leading cause of premature death among schizophrenia patients, who die from heart and blood vessel disorders at a rate double that of persons without the mental disorder.

GSU associate professor receives federal grant to bolster flu vaccine research

Sang-Moo Kang, associate professor at Georgia State University's Center for Inflammation, Immunity and Infection, has received a federal five-year, $3.4 million grant to bolster research that will lead to better flu vaccines and vaccines against respiratory syncytial virus (RSV), a disease for which there is no immunization.

Viewpoints: Debating P4P; ‘Tactical retreat' by GOP; The virtues of across-the-board spending cuts

Instead of granting automatic pay increases, N.Y. City's public hospital system will pay them based on how well they reduce costs, increase patient satisfaction and improve the quality of care. The Health and Hospitals Corporation, which runs the city's 11 public hospitals, deserves praise for an ambitious proposal that will need to be refined as it is put into practice.

Researchers to develop new diagnostic tools and treatments for people with rare diseases

A multi-million Euro initiative is bringing together researchers from across the world to develop new diagnostic tools and new treatments for people with rare diseases and to connect research data in this area on a global scale.

Salk Institute to establish Helmsley Center for Genomic Medicine

The Salk Institute for Biological Studies has received a $42 million gift-the largest in the Institute's history-to establish the Helmsley Center for Genomic Medicine (HCGM), a research center dedicated to decoding the common genetic factors underlying many complex chronic human diseases.

SLU team discovers molecular pathway that contributes to triple-negative breast cancer

In research published in the Jan. 17 issue of The Journal of Cell Biology, a team led by Susana Gonzalo, Ph.D., assistant professor of biochemistry and molecular biology at Saint Louis University, has discovered a molecular pathway that contributes to triple-negative breast cancer, an often deadly and treatment resistant form of cancer that tends to strike younger women.

Law banning genetic discrimination doesn't apply to some insurers

NPR examines a key loophole in the law designed to keep health insurers from raising rates or denying coverage because of genetic issues. The law doesn't apply to life, disability or long-term-care insurance.

Researchers identify four new genetic regions associated with Behcet's disease

Researchers have identified four new regions on the human genome associated with Behcet's disease, a painful and potentially dangerous condition found predominantly in people with ancestors along the Silk Road.

Researchers study response of living cells to artificial protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques-collectively referred to as synthetic biology-have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes.

New light on how epigenetic signals may function together to determine fate of stem cell

Long-standing research efforts have been focused on understanding how stem cells, cells capable of transforming into any type of cell in the body, are capable of being programmed down a defined path to contribute to the development of a specific organ like a heart, lung, or kidney. Research from the University of North Carolina at Chapel Hill School of Medicine has shed new light on how epigenetic signals may function together to determine the ultimate fate of a stem cell.

Researchers reveal critical role of BRCA1 gene in maintenance of hair follicle stem cells

Our DNA, which stores our genetic information, is constantly submitted to damage. If not properly repaired, DNA damage can lead to cell death, which may in turn lead to tissue exhaustion and ageing, or induce mutations resulting in uncontrolled cell proliferation and cancer. Brca1 is a key gene that mediates DNA repair. Mutations in Brca1 lead to familial and sporadic breast and ovarian cancer in humans.

AAV-based gene therapy cocktail may help extend lives of children with Canavan disease

Results of a clinical trial that began in 2001 show that a gene therapy cocktail conveyed into the brain by a molecular special delivery vehicle may help extend the lives of children with Canavan disease, a rare and fatal neurodegenerative disorder.

Researchers identify possible heredity mechanism that predisposes children to ALL

Researchers at the Sainte-Justine University Hospital Center and the University of Montreal have found a possible heredity mechanism that predisposes children to acute lymphoblastic leukemia (ALL), the most common type of blood cancer in children. According to their findings published in Genome Research, the presence of a genetic defect in the egg or sperm from which children having ALL arise may be a prerequisite for the disease to develop.

TU Darmstadt’s biosensor can diagnose African sleeping sickness before it breaks out

African sleeping sickness is an infectious disease that is widespread south of the Sahara Desert. Although the around sixty million people residing in tropical Africa run the risk of becoming infected with the disease every day, only around four million of them are monitored for the disease by disease-control authorities.
