Discovery provides target to potentially halt the process, prevent cancers Biologists reported today in Nature that they have identified two pathways through which chromosomes are rearranged in mammalian cells. These types of changes are associated with some cancers and inherited disorders in people. "Our finding provides a target to prevent these rearrangements, so we could conceivably prevent cancer in some high-risk people," said senior author Edward P. (Paul) Hasty, D.V.M., of the...

Scientists Discover Aneuploidy In Single-celled Organisms
2013-08-14 14:57:39

University of Luxembourg Baker's yeast is a popular test organism in biology. Yeasts are able to duplicate single chromosomes reversibly and thereby adapt flexibly to environmental conditions. Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg, in collaboration with colleagues from the US Institute for Systems Biology (ISB) in Seattle, have now systematically studied the genetics of this process, which biologists refer to as aneuploidy. The...

The guiding founding principles of the XXY Brain Trust: 47,XXYs are all genders, not just male; the most important aspect of life for 47,XXYs (Klinefelter Syndrome) is appropriate medical care for individuals who express themselves in a range of gender from female to male. Don't try to fix XXYs or variants with hormones or surgical intervention; wait until they are old enough to make their own decisions about their body and identity. Truckee, CA (PRWEB) August 07, 2013 There is a new...

The media has recently been filled with headlines proclaiming that Down syndrome has been “cured”. These statements are not accurate, but that is not to say the findings are without significance. Philadelphia, PA (PRWEB) July 24, 2013 The media has recently been filled with headlines proclaiming that Down syndrome has been “cured”. Down syndrome, or trisomy 21, is the most common survivable chromosomal abnormality and is caused by the presence at conception of a third copy of...

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...

Down's Syndrome Genes Shut Off In New Breakthrough
2013-07-18 05:30:06

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...
