Scientists discover new evidence for role of epigenetic changes on premature aging diseases

Scientists at the Bellvitge Biomedical Research Institute in Barcelona, Spain have found new evidence for the role of epigenetic changes (those heritable alterations in gene expression caused by mechanisms other than changes in DNA sequence) on premature aging diseases.

Scientists identify specific p53 pocket that can be targeted by cancer-fighting drugs

UC Irvine biologists, chemists and computer scientists have identified an elusive pocket on the surface of the p53 protein that can be targeted by cancer-fighting drugs. The finding heralds a new treatment approach, as mutant forms of this protein are implicated in nearly 40 percent of diagnosed cases of cancer, which kills more than half a million Americans each year.

Study investigates R1441G mutation of Parkinson's disease

A team from the UPV/EHU-University of the Basque Country came across a mutation of the LRRK2 gene in 2004, which is particularly prevalent among the population of Gipuzkoa. It is the R1441G mutation and is known as the Basque mutation.

Innate lymphoid cells may be new therapeutic target in treating atopic dermatitis

The increasing incidence of allergic skin diseases, and the accompanying economic burden and heightened risk of developing other allergic conditions, have spurred researchers to look for better ways to control these immune system-based disorders.

Endothelial cells can trigger changes in cancer cells without direct contact

Blood vessels that supply oxygen and nutrients to tumors can also deliver something else - a signal that strengthens nearby cancer cells, making them more resistant to chemotherapy, more likely to spread to other organs and more lethal, scientists at The University of Texas MD Anderson Cancer Center report online in Cancer Cell.

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.

Notch protein responsible for activating GATA2 gene to generate hematopoietic stem cells

Researchers from the group on stem cells and cancer at IMIM (Hospital del Mar Medical Research Institute) have deciphered one of the gene regulation circuits which would make it possible to generate hematopoietic blood cells, i.e. blood tissue stem cells.

Moderate gum disease causes severe infection and inflammation in AIDS animal model

Texas Biomed scientists in San Antonio have found that moderate gum disease in an animal model exposed to an AIDS- like virus had more viral variants causing infection and greater inflammation. Both of these features have potential negative implications in long term disease progression, including other kinds of infections, the researchers say in a new report.

NIH stresses importance of genomics in nursing care in medical literature

On April 14, 2003 a map of the human genome was completed, ushering in a new era of genetics in medicine with applications that include genetic testing; newborn screening; susceptibility to diseases such as cancer, cardiovascular disease, or psychiatric conditions; screening, diagnosis and monitoring of disease; and treatment planning.

Microbiologists discover new pathway to improve vaccines against tuberculosis

A new pathway for improving vaccines against tuberculosis has been discovered by microbiologists at the University at Buffalo in collaboration with researchers at other universities, according to a paper in the journal Mucosal Immunology, published by the Nature group.

Soft x-ray electrostatic precipitator protects mice against airborne pathogens

A new device called a soft x-ray electrostatic precipitator protected immunocompromised mice from airborne pathogenic bacteria, viruses, ultrafine particles, and allergens, according to a paper published online ahead of print in the journal Applied and Environmental Microbiology.

Bioelectric signals can identify cells that are likely to develop into tumors

Biologists at Tufts University School of Arts and Sciences have discovered a bioelectric signal that can identify cells that are likely to develop into tumors. The researchers also found that they could lower the incidence of cancerous cells by manipulating the electrical charge across cells' membranes.

Study supports hypothesis that disulfiram reduces drug consumption by blocking DβH

Disulfiram was the first medication approved for the treatment of alcoholism over 50 years ago. It works, at least in part, by preventing the metabolism of an alcohol by-product, acetaldehyde. High levels of acetaldehyde in the body quickly cause unpleasant symptoms, including nausea, vomiting, headache, and accelerated heart rate. Thus, disulfiram provides a very strong incentive to avoid drinking.

Study demonstrates new fragile genomic sites responsible for chromosomal alterations in tumors

Cancer arises from the accumulation of mutations and structural changes in chromosomes, which in some cases give rise to combinations that favour the growth or expansion of the disease. In this context, chromosomes tend to lose or duplicate entire regions, although, the mechanisms that initiate these chromosomal abnormalities are not fully understood.

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.

SINEUP allows scientists to target individual genes in cells to increase protein production

One of the most innovative biotechnologies of the last decade has recently been developed. SINEUP allows scientists, for the first time, to target individual genes in cells to knockup, or increase, the amount of protein they make. The technique will improve Protein manufacture, analyse the function of genes and engineer improved cell function.

Interferon retreatment of chronic hepatitis C may be harmful

People with hepatitis C and chronic liver disease who relapsed or failed to respond to initial treatment are unlikely to improve on interferon retreatment. In fact, they may face an increased risk of dying sooner, and are likely to experience a variety of adverse effects, according to an updated systematic review published in The Cochrane Library.
