The genes are composed of DNA and are carried on the chromosomes. Genes direct the production of all the molecules that form the structures that of a cell. Genes determine the inherited characteristics that distinguish one individual from another. Each human has an estimated 90,000 genes.
Penn study finds link between Parkinson’s disease genes and manganese poisoning – A connection between genetic and environmental causes of Parkinson’s disease has been discovered by a research team led by Aaron D. Gitler, PhD, Assistant Professor in the Department of Cell and Developmental Biology at the University of Pennsylvania School of Medicine.
Animal eggs not suitable substitutes to produce stem cells – Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications.
Stress may hasten the growth of melanoma tumors but common beta-blocker medications might slow that progress. – For patients with a particularly aggressive form of skin cancer malignant melanoma stress, including that which comes from simply hearing that diagnosis, might amplify the progression of their disease.
The genes in your congeniality: Researchers identify genetic influence in social networks – Researchers from Harvard University and the University of California, San Diego have found that our place in a social network is influenced in part by our genes.
Indiana University discovery may provide new approach to HIV treatment – Researchers at the Indiana University School of Medicine have identified a potential new target in the war on HIV/AIDS.
By 2010 India’s population will suffer approximately 60% of the world’s heart disease. – Heart disease is the number one killer in the world and India carries more than its share of this burden. Moreover, the problem is set to rise: it is predicted that by 2010 India’s population will suffer approximately 60% of the world’s heart disease.
Obesity starts in the head? Six newly discovered genes for obesity have a neural effect – Obesity is known to increase the risk of chronic disorders, such as diabetes (type 2). An international team of scientists with German participation through the Helmholtz Zentrum M?nchen identified six new obesity genes.
Early childhood diet may influence future health. New kinesiology research shows early diet may have a profound influence on adult obesity, diabetes – If you have trouble keeping weight off and you’re wondering why ? the surprising answer may well be the cheeseburgers you ate ? when you were a toddler.
Salk researchers develop novel brain cancer glioblastoma mouse model. – Researchers at the Salk Institute for Biological Studies have developed a versatile mouse model of glioblastoma-the most common and deadly brain cancer in humans-that closely resembles the development and progression of human brain tumors that arise naturally.
Scientists can now differentiate between healthy cells and cancer cells and normal stem cells. – One of the current handicaps of cancer treatments is the difficulty of aiming these treatments at destroying malignant cells without killing healthy cells in the process.
Few DNA repair genes maintain association with cancer in field synopsis – Variants of numerous DNA repair genes initially appeared to be statistically significantly associated with cancer risk in epidemiological studies.
Researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus. – By mixing and matching a contemporary flu virus with the “Spanish flu” – a virus that killed between 20 and 50 million people 90 years ago in history’s most devastating outbreak of infectious disease – researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.
