A 'network map' of genes involved in pain perception Scientists in Australia and Austria have described a "network map" of genes involved in pain perception. The work, published in the journal PLOS Genetics should help identify new analgesic drugs. Dr Greg Neely from the Garvan institute of Medical Research in Sydney and Professor Josef Penninger from the Austrian Academy of Sciences in Vienna had previously screened the 14,000 genes in the fruit fly genome and identified 580 genes...

Genetic Test Reveals More About Potential Birth Defects Than Conventional Methods

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...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
