Genetic Testing Technique Will Accelerate Personalized Medicine
2013-11-04 03:57:33

redOrbit Staff & Wire Reports - Your Universe Online In a development expected to improve the process of matching organ donors and understanding how genes contribute to diseases, researchers have devised a method that can help determine whether or not a specific genetic sequence came from an individual’s mother or father. The technique, which was developed by experts from the Ludwig Institute for Cancer Research and is described in the latest edition of the journal Nature...

Every case of cancer originates from changes in a person's genetic material (mutations). These usually occur as "somatic mutations" in individual cells during an individual's lifetime, rather than being inherited from a person's parents. "Over time, the original damaged cell accumulates additional mutations, and it is still largely unknown why," says Prof. Roland Eils, who leads bioinformatics departments both at DKFZ and Heidelberg University. By studying when and where mutations occur...

First 3D Pictures Of Chromosome Structure Revealed
2013-09-25 15:40:45

Biotechnology and Biological Sciences Research Council A new method for visualizing chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with. Scientists at the BBSRC-funded Babraham Institute, working with the University of Cambridge and the Weizmann Institute, have produced beautiful 3D models that more accurately show their complex shape and the way DNA within them folds up. The X-shape, often used to...

In a study to be published in the journal Nature, two Dartmouth researchers have found that the protein cyclin A plays an important but previously unknown role in the cell division process, acting as a master controller to ensure the faithful segregation of chromosomes during cell division. Cell division is the process in which cells reproduce by splitting into two identical copies. This process happens trillions of times in an average person's lifetime. To generate two identical copies,...

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...

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...

Genes Regulated By Newly Found CLAMP Protein
2013-07-18 12:49:15

Brown University They say a good man is hard to find. Were it not for a newly discovered protein, the X chromosome of a male fruit fly could never be found by a gene-regulating complex that male flies need to develop and survive. And that case is just one example of what the new finding means. More generally, the research provides biologists with a model of how proteins that govern gene transcription find their targets on chromosomes, a process that’s essential to healthy...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
