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...

UC Riverside geneticists show the COPIA-R7 transposon enhances the immunity of its host against a pathogenic microorganism Transposons are DNA elements that can multiply and change their location within an organism's genome. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk DNA." Also referred to as transposable elements and jumping genes, they are snippets of "selfish DNA" that spread in their host genomes serving no other biological purpose but...

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. The discovery, by Bradley R. Cairns, PhD, Senior Director of Basic Science at HCI and a professor in the Department of Oncological Sciences, is reported in this week's online...

Epigenetic memory may pass RNA silencing from 1 generation to the next Organisms employ a fascinating array of strategies to identify and restrain invasive pieces of foreign DNA, such as those introduced by viruses. For example, many viruses produce double-stranded (ds)RNA during their life cycle and the RNA interference (RNAi) mechanism is thought to recognize this structural feature to initiate a silencing response. Now, UMass Medical School researchers have identified a mechanism...

A DICER protein, known to produce tiny RNAs in cells, also helps complete an important step in gene expression, according to research on Arabidopsis thaliana. The expression of a gene, when an organism's DNA is transcribed into a useable product, requires activation via a promoter or an external trigger. Plant research to be published in Science helps to show that later stages of transcription are just as important. This is likely to apply to other organisms, including humans....
