The update will result in improved patient prognoses, better informed patient care decisions and reduced costs. (PRWEB) July 22, 2013 Signal Genetics today announced that it has launched an update to its MyPRS gene expression assay for patients with Multiple Myeloma, which will improve patient prognoses, enable better informed patient care decisions, and ultimately reduce costs. Every MyPRS test performed now includes an analysis of an additional set of 813-genes within the patient’s...

Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the "female" counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized role in sperm production. This surprising finding, reported by Whitehead Institute scientists in a paper published online this week in the journal Nature Genetics, is paired with another unexpected outcome: despite its reputation as the...

Susan Bowen for redOrbit.com - Your Universe Online Scientists at the University of Massachusetts Medical School have made a huge breakthrough in our understanding of Down's syndrome. They reported in the online science journal Nature, that in a lab, they have switched off the extra chromosome that causes the disorder in humans. This is the proof-of-principal that opens the doorway for exciting new discoveries about this condition. Down's syndrome is the world's leading genetically...

Penn State The Y chromosomes of cattle have more genes and are more active than the Y chromosomes of other primates, according to researchers. This discovery may help biologists better understand how cattle and other mammals evolved, as well as help animal breeders and farmers better maintain and enhance fertility in the cattle industry, said Wansheng Liu, associate professor of animal genomics, Penn State. "Low fertility is a big problem for the dairy and beef industry," Liu said....

Findings of disrupted micronuclei may prove to be a valuable tool for detecting cancer Scientists studying cancer development have known about micronuclei for some time. These erratic, small extra nuclei, which contain fragments or whole chromosomes that were not incorporated into daughter cells after cell division, are associated with specific forms of cancer and are predictive of poorer prognosis. In a new study, published on July 3 in Cell, a team of scientists at the Salk Institute...

From one family to another, the Chengs publish a free book for families dealing with the loss of an infant. Los Angeles, CA (PRWEB) June 18, 2013 In the fall of 2008, Melanie Tioleco-Cheng received the news that no expectant mother ever wants to hear. Her baby was diagnosed with Trisomy 18. As a physician, she knew exactly what this meant for her second child, Macy, and even more about how little her chance of survival was in light of her heart and lung problems. But, how would Melanie...

New research has found that routine screening using a non-invasive test that analyzes fetal DNA in a pregnant woman's blood can accurately detect Down's syndrome and other genetic fetal abnormalities in the first trimester. Published early online in Ultrasound in Obstetrics & Gynecology, the results suggest that the test is superior to currently available screening strategies and could reshape standards in prenatal testing. Current screening for Down's syndrome, or trisomy 21, and...
