For the first time, researchers have corrected a disease-causing mutation in early stage human embryos with gene editing. The technique, which uses the CRISPR-Cas9 system, corrected the mutation for a heart condition at the earliest stage of embryonic development so that the defect would not be passed on to future generations. With advances in stem … Read more
Changes in scores of genes contribute to autism risk — Newfound genetic differences provide many hints at causes – Small differences in as many as a thousand genes contribute to risk for autism or autism spectrum disorder (ASD). This new study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children, and unrelated individuals.
Biomarker predicts effectiveness of brain cancer treatment – Researchers at the University of California, San Diego School of Medicine have identified a new biomarker that predicts whether glioblastoma – the most common form of primary brain cancer – will respond to chemotherapy.
New test predicts the risk of non-hereditary breast cancer — A simple blood test is currently in development that could help predict the likelihood of a woman developing breast cancer – A simple blood test is currently in development that could help predict the likelihood of a woman developing breast cancer, even in the absence of a high-risk BRCA1 gene mutation. This new research is published in the Genome Medicine.
How a versatile gut bacterium helps us get our daily dietary fiber – A common gut bacterium – Bacteroides ovatus – helps us metabolize a main component of dietary fibre xyloglucan from the cell walls of fruits and vegetables, revealed by researchers from University of British Columbia in the journal Nature.
FDA Orders Genetic Testing Firm 23andme to Stop Marketing DNA Analysis Service — Blocks Sale of a Company’s Mail-Order Gene Tests – The Food and Drug Administration, USA has ordered 23andme – the maker of a popular genetic-testing kit to stop sales of its heavily marketed product, saying the mail-order tests haven’t been proven effective and could dangerously mislead people about their health.
Meat, egg and dairy nutrient essential for brain development — Deficiency of asparagine synthetase caused by rare genetic disorder affects brain development – Asparagine, found in foods such as meat, eggs, and dairy products, was until now considered non-essential because it is produced naturally by the body. Researchers at the University of Montreal and its affiliated CHU Sainte-Justine Hospital found that the amino acid is essential for normal brain development.
Ordinary skin cells morphed into functional brain cells — Scientists at CWRU School of Medicine discover new technique that holds promise for the treatment of multiple sclerosis and cerebral palsy – Researchers at Case Western Reserve School of Medicine have discovered a technique that directly converts skin cells to the type of brain cells destroyed in patients with multiple sclerosis, cerebral palsy and other so-called myelin disorders.
NIH scientists identify molecular link between metabolism and breast cancer – A protein associated with conditions of metabolic imbalance, such as diabetes and obesity, may play a role in the development of aggressive forms of breast cancer, according to new findings by researchers at the National Cancer Institute (NCI).
UNC Lineberger scientists lead cancer genome analysis of breast cancer — Team identifies genetic causes and similarity to ovarian cancer – The researchers, including a large group from the University of North Carolina at Chapel Hill, reported their study about genetic characterization of 800 breast tumors, finding some of the genetic causes of the most common forms of breast cancer, providing clues for new therapeutic targets, and identifying a molecular similarity between one sub-type of breast cancer and ovarian cancer.
