New understanding of X chromosome inactivation

New understanding of X chromosome inactivation

ScienceDaily (Nov. 27, 2012) — In a paper published in the Nov. 21 issue of Cell , a team led by Mauro Calabrese, a postdoctoral fellow at the University of North Carolina in the lab of Terry Magnuson, chair of the department of genetics and member of the UNC Lineberger Comprehensive Cancer Center, broadens the understanding of how cells regulate silencing of the X chromosome in a process known as X-inactivation.

Minority report: Insight into subtle genomic differences among our own cells

ScienceDaily (Nov. 18, 2012) — Stanford University School of Medicine scientists have demonstrated, in a study conducted jointly with researchers at Yale University, that induced-pluripotent stem cells — the embryonic-stem-cell look-alikes whose discovery a few years ago won this year’s Nobel Prize in medicine — are not as genetically unstable as was thought. The new study, published online Nov Continue reading

DNA packaging discovery reveals principles by which CRC mutations may cause cancer

ScienceDaily (Nov. 16, 2012) — 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 Continue reading

Arthritis study reveals why gender bias is all in the genes

ScienceDaily (Nov. 16, 2012) — Researchers have pieced together new genetic clues to the arthritis puzzle in a study that brings potential treatments closer to reality and could also provide insights into why more women than men succumb to the disabling condition. Continue reading

Class of RNA molecules protects germ cells from damage

ScienceDaily (Nov. 15, 2012) — Passing one’s genes on to the next generation is a mark of evolutionary success. So it makes sense that the body would work to ensure that the genes the next generation inherits are exact replicas of the originals Continue reading

Cancer therapy: Nanokey opens tumors to attack

ScienceDaily (Nov. 14, 2012) — There are plenty of effective anticancer agents around. The problem is that, very often, they cannot gain access to all the cells in solid tumors. Continue reading

Family tree stops MRSA outbreak

Family tree stops MRSA outbreak

13 November 2012 Last updated at 20:03 ET By James Gallagher Health and science reporter, BBC News An outbreak of the hospital superbug MRSA has been brought to an end by UK doctors cracking the bacterium’s genetic code. It led to them finding one member of staff at Rosie Hospital, in Cambridge, who may have unwittingly carried and spread the infection. They say it is the first time rapid genetic testing has been used to track and then stop an outbreak Continue reading

New type of bacterial protection found within cells: Novel immune system response to infections discovered

New type of bacterial protection found within cells: Novel immune system response to infections discovered

ScienceDaily (Nov. 13, 2012) — UC Irvine biologists have discovered that fats within cells store a class of proteins with potent antibacterial activity, revealing a previously unknown type of immune system response that targets and kills bacterial infections. Continue reading

‘Calm down’ genes treat epilepsy

‘Calm down’ genes treat epilepsy

12 November 2012 Last updated at 12:11 ET By James Gallagher Health and science reporter, BBC News Adding “calm down” genes to hyperactive brain cells has completely cured rats of epilepsy for the first time, say UK researchers. They believe their approach could help people who cannot control their seizures with drugs. Continue reading

New form of brain plasticity: How social isolation disrupts myelin production

New form of brain plasticity: How social isolation disrupts myelin production

ScienceDaily (Nov. 11, 2012) — Animals that are socially isolated for prolonged periods make less myelin in the region of the brain responsible for complex emotional and cognitive behavior, researchers at the University at Buffalo and Mt Continue reading
