Domestic Goat Reference Genome Sequence Complete
2012-12-24 05:45:56

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers announced on Sunday they had completed the first high-quality reference genome of the domestic goat (Capra hircus), marking the first time the DNA of a ruminant animal has been sequenced. "Goats are recognized as an important member of the world livestock industry, and with many unique biological features," officials from BGI Shenzen, one of the institutions responsible for the feat, explained...

Genome Sequencing Complete On Three Lophotrochozoans
2012-12-20 08:31:54

redOrbit Staff & Wire Reports - Your Universe Online With the sequencing of three new members of a group of creatures known as lophotrochozoans, researchers from a pair of US universities and the Department of Energy's Joint Genome Institute (JGI) have more than doubled the number of genomes from these often overlooked marine creatures. Scientists from the JGI, Rice University, and the University of California-Berkeley announced on Thursday that they had sequenced and published the...

In the twentieth century the sequencing of an entire genome of a higher (eukaryotic) organism was a truly exceptional event — by the end of the year 2000, only four such sequences were available.  Since then, technological advances have put whole-genome sequencing within the reach of many more groups and new sequences have appeared at regular intervals. Viola Nolte in the group of Christian Schlötterer at the University of Veterinary Medicine, Vienna has just published...

Scientists Identify Genes Related To Crohn’s Disease
2012-12-14 08:15:46

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University College London (UCL) recently revealed that they had identified over 200 genes for Crohn´s Disease, a chronic bowel condition. The scientists believe that knowledge about genetic factors of complex diseases will help in understanding patients´ symptoms and providing better treatment. The study looked at the entire human genome, and the findings are featured in a recent edition of The...

Honeybee Histone Code Found
2012-12-12 20:06:33

Lee Rannals for redOrbit.com — Your Universe Online Researchers have uncovered a new element of the honeybee's genetic makeup, shedding light on why bees are so sensitive to environmental changes. Scientists found honeybees have a "histone code," which is a series of marks on the histone proteins around which their DNA is wrapped to help fit into the nucleus of a cell. This code is known to exist in humans and other organisms in order to control changes in cell development....

Homosexuality May Have Roots In Epigenetic Markers
2012-12-12 08:28:52

[ Watch the Video: Researchers Say They Have Found Genetic Switches for Homosexuality ] Connie K. Ho for redOrbit.com — Your Universe Online A new study from the National Institute for Mathematical and Biological Synthesis (NIMBioS) reveals that epigenetics, rather than genetics, could be the basis for homosexuality. To begin, epigenetics looks at how gene expression is managed by temporary switches, known as epi-marks. In the report, recently published online in The Quarterly...

Daily Liver Cycles Controlled By More Than 3,000 Epigenetic Switches
2012-12-11 10:16:12

Salk Institute Salk findings may help explain connections between dietary schedules and chronic disease When it's dark, and we start to fall asleep, most of us think we're tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the level of individual organs, and even genes. Now, scientists at the Salk Institute have determined the specific genetic switches that sync liver activity to the circadian cycle. Their finding gives...

New Genetic Fingerprint Resides In Your Belly
2012-12-06 12:35:08

Washington University School of Medicine Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine. The research is the first to catalog the genetic variation of microbes that live in the gut, where they extract nutrients from food, synthesize vitamins, protect against infections, and produce compounds that naturally reduce inflammation....
