Fragile X Syndrome
2014-02-28 13:24:30

Brett Smith for redOrbit.com - Your Universe Online New research from a team of American researchers has found a genetic mechanism that shuts off the gene associated with fragile X syndrome – which causes developmental disorders such as mental retardation and autism. According to the team’s report in the journal Science, they were successfully able to a test drug that blocks this blocking mechanism. While it has been known that the syndrome is driven by the excessive repetition...

As the price for decoding a person's DNA keeps dropping, expectations for personalized medicine based on specific genetic profiling rise. But translating an individual's genetic data into finely tailored medical treatments still faces major challenges, explains a new article in Chemical & Engineering News (C&EN), the weekly magazine of the American Chemical Society. Rick Mullin, senior editor at C&EN, notes that advances in DNA sequencing have allowed researchers to design some...

How Well Did You Sequence That Genome?

National Institute of Standards and Technology (NIST) In December 2013, the U.S. Food and Drug Administration approved the first high-throughput DNA sequencer (also known commonly as a "gene sequencer"), an instrument that allows laboratories to quickly and efficiently sequence a person's DNA for genetic testing, medical diagnoses and perhaps one day, customized drug therapies. Helping get the new device approved was another first: the initial use of a reference set of standard genotypes,...

Technological discovery Cells in our body are constantly dividing to maintain our body functions. At each division, our DNA code and a whole machinery of supporting components has to be faithfully duplicated to maintain the cell’s memory of its own identity. Researchers at BRIC, University of Copenhagen, have developed a new technology that has revealed the dynamic events of this duplication process and the secrets of cellular memory. The results are published in Nature Cell Biology....

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
