Genetic Test Reveals More About Potential Birth Defects Than Conventional Methods
2012-12-06 11:43:12

Lawrence LeBlond for redOrbit.com - Your Universe Online Two new papers published in the New England Journal of Medicine (NEJM) show that genetic testing in early pregnancy reveals far more about potential birth defects and stillbirth risk than current prenatal testing does, based on a multi-center clinical trial using both methods. The clinical trials showed that 6 percent of certain fetuses declared normal by conventional prenatal tests were found to have genetic abnormalities using...

The surface of your skin, called the epidermis, is a complex mixture of many different cell types – each with a very specific job. The production, or differentiation, of such a sophisticated tissue requires an immense amount of coordination at the cellular level, and glitches in the process can have disastrous consequences. Now, researchers at the Stanford University School of Medicine have identified a master regulator of this differentiation process. "Disorders of epidermal...

Mapping The Evolution Of Human Intellect Through Epigenetics

April Flowers for redOrbit.com - Your Universe Online Hundreds of small regions of the genome that appear to be uniquely regulated in human neurons have been identified in a new study led by the University of Massachusetts. Humans are distinguished from other primates, such as monkeys and apes, by these regulatory differences. These features, which are neurons at the core of our cognitive abilities, may ultimately hold the key to our intellectual prowess. They might also be key to our...

A new discovery from researchers at Huntsman Cancer Institute (HCI) at the University of Utah concerning a fundamental understanding about how DNA works will produce a "180-degree change in focus" for researchers who study how gene packaging regulates gene activity, including genes that cause cancer and other diseases. The discovery, by Bradley R. Cairns, PhD, Senior Director of Basic Science at HCI and a professor in the Department of Oncological Sciences, is reported in this week's online...

Unlocking DNA Repair Secrets
2012-10-31 12:53:16

University of Sheffield Scientists from the University of Sheffield have unlocked one of the secrets to DNA repair —helping doctors identify DNA base damage and a patient's susceptibility to certain types of cancer. Groundbreaking research led by Dr David Williams from the University of Sheffield's Department of Chemistry and an international collaboration of expert researchers has discovered how some proteins recognize damaged bases within DNA which, if untreated, could lead to...

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 fibers. The researchers, whose findings are published in EMBO reports, reveal that the mouse genome consists of 10-nm chromatin fibers but did not find evidence for the wider 30-nm fibers that were previously thought to be important components of the DNA architecture. “DNA is an exceptionally long...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
