A research team centered at Brown University has compiled the largest and most stringently validated list of RNA editing sites in the fruit fly Drosophila melanogaster, a stalwart of biological research. Their research, which yielded several insights into the model organism's fundamental biology, appears Sept. 29 in Nature Structural & Molecular Biology. The "master list" totals 3,581 sites in which the enzyme ADAR might swap an "A" nucleotide for a "G" in an RNA molecule. Such 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...

Sometimes, when the DNA in a cell is copied during cell division, there is a mistake. A large portion of the genetic material could be duplicated or deleted. In each instance, there is often a greatly enhanced potential for serious genetic disease. Such changes are known as copy number variation (CNV) referring to the numbers of copies of a gene. Instead of ‘letters of the DNA alphabet’ being changed or missing, whole sentences, entire paragraphs or even pages/volumes of the encyclopedia...

Pioneering new research from a team of Indiana University Bloomington biologists has shown for the first time that a protein which has been long known to be critical for the initiation of protein synthesis in all organisms can also play a role in the regulation of gene expression in some bacteria, and probably land plants as well. The protein, called translation initiation factor 3, or IF3, is one of three proteins that make up the core structure of the machinery needed to guide the...

University of Adelaide researchers have identified a likely molecular pathway that causes a group of untreatable neurodegenerative diseases, including Huntington's disease and Lou Gehrig's disease. The group of about 20 diseases, which show overlapping symptoms that typically include nerve cell death, share a similar genetic mutation mechanism ‒ but how this form of mutation causes these diseases has remained a mystery. "Despite the genes for some of these diseases having been...

Getting the message about bitter taste Do you love chomping on raw broccoli while your best friend can't stand the healthy veggie in any form or guise? Part of the reason may be your genes, particularly your bitter taste genes. Over the past decade, scientists at the Monell Center and elsewhere have made headway in understanding how variants of bitter taste receptor genes can help account for how people differ with regard to taste perception and food choice. However, some perplexing...

Next Generation Sequencing Reveals Absence Of DNA In Sub-fossilized Insects

University of Manchester Research just published in the journal PLOS ONE by a team of researchers from the Faculty of Life Sciences at The University of Manchester can now confirm that the existence of DNA in amber fossils is highly unlikely It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the fascination of the public for two decades....

Near-optimal Genetic Code Model Created By Researchers
2013-08-29 04:15:01

redOrbit Staff & Wire Reports - Your Universe Online By creating a model of genetic code evolution, researchers have discovered new information about how RNA signaling could have developed into the “near-optimal” modern genetic code. Lead author Justin Jee, a doctoral student at NYU School of Medicine, and colleagues set out to account for the composition of the genetic code, which makes it possible for proteins to be constructed from amino acids with high specificity based on...

Discovery of long non-coding RNA's role in neurogenesis may lead to cures for diseases such as Alzheimer's diseaseSingapore, Aug 28, 2013 - (ACN Newswire) - Scientists at A*STAR's Genome Institute of Singapore (GIS) have discovered an unusual gene that controls the generation of neurons[1]. This important finding, which is crucial in understanding serious diseases of the brain such as Alzheimer's disease, was reported in the 8th August 2013 issue of the prestigious...

In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function. A paper from the University of Wisconsin–Madison in the August issue of the journal GENETICS takes genome editing to a new level in fruit flies, demonstrating a remarkable level of fine control and, importantly, the transmission of those engineered genetic changes across generations. Both features are key...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
