Genome-wide changes result from silencing extra chromosome, scientists report at ASHG 2013 The first evidence that the underlying genetic defect responsible for trisomy 21, also known as Down syndrome, can be suppressed in laboratory cultures of patient-derived stem cells was presented today (Oct. 22) at the American Society of Human Genetics 2013 annual meeting in Boston. People with Down syndrome are born with an extra chromosome 21, which results in a variety of physical and...

Plug And Play Synthetic Biology - Rewriting An Entire Genome
2013-10-19 04:15:01

April Flowers for redOrbit.com - Your Universe Online A team of scientists from Harvard and Yale have recorded the entire genome of the bacteria E. coli, and in a dramatic demonstration of the potential of rewriting an organism's genetic code, they have improved the bacterium's ability to resist viruses. "This is the first time the genetic code has been fundamentally changed," according to Farren Isaacs, assistant professor of molecular, cellular, and developmental biology at Yale....

Nature Study Shows Distinct Behavior of Proteins Reflects Common Biochemical Principles Researchers from Case Western Reserve University School of Medicine have found unexpected similarities between proteins that were thought to be fundamentally different. The team studied how proteins bind to RNA, a process required for gene expression. It is known that some proteins only bind RNAs with certain sequences. Other proteins have been deemed “non-specific” because they interact with...

Understanding how genes act in specific tissues is critical to our ability to combat many human diseases, from heart disease to kidney failure to cancer.  Yet isolating individual cell types for study is impossible for most human tissues. A new method developed by researchers at Princeton University and the University of Michigan called “in silico nano-dissection” uses computers rather than scalpels to separate and identify genes from specific cell types, enabling the systematic study...

By detailing a process required for repairing DNA breakage, scientists at the Duke Cancer Institute have gained a better understanding of how cells deal with the barrage of damage that can contribute to cancer and other diseases. The insights, reported online the week of Sept. 30, 2013, in the journal Proceedings of the National Academy of Sciences, build on earlier work by the research team and identify new prospects for developing cancer therapies. The researchers have focused on a...

How Rare 'Words' In Bacterial Genes Boost Protein Production
2013-09-27 07:29:50

Wyss Institute for Biologically Inspired Engineering at Harvard Scientists routinely seek to reprogram bacteria to produce proteins for drugs, biofuels and more, but they have struggled to get those bugs to follow orders. But a hidden feature of the genetic code, it turns out, could get bugs with the program. The feature controls how much of the desired protein bacteria produce, a team from the Wyss Institute for Biologically Inspired Engineering at Harvard University reported in the...

snash
  • To talk saucily.
  • Insolent, opprobrious language; impertinent abuse.
This word is Scots in origin and probably imitative.
