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...

Biologists of the University of Zurich have developed a method to visualize the activity of genes in single cells. The method is so efficient that, for the first time, a thousand genes can be studied in parallel in ten thousand single human cells. Applications lie in fields of basic research and medical diagnostics. The new method shows that the activity of genes, and the spatial organization of the resulting transcript molecules, strongly vary between single cells. Whenever cells activate...

The Mystery Of Handedness
2013-10-02 05:23:47

April Flowers for redOrbit.com - Your Universe Online Most of us are right handed, with only approximately ten percent of the population of the UK, and the world at large, being left handed. But why that is so remains a mystery. Two independent studies might have given us some clues to the mystery, however. Professor John Armour and Dr. Angus Davison from The University of Nottingham collaborated with University College London's Professor Chris McManus to rule out a "strong genetic...

Supplementation at preventive intake levels could represent potential savings of billions of dollars. Chesterfield, MO (PRWEB) September 30, 2013 Reliv International, Inc. (NASDAQ: RELV), a maker of nutritional supplements that promote optimal health, today hailed the results of a new financial report on supplements as an indication of the economic potential of nutritional epigenetics. “It’s an eye-opening report in its own right,” said Dr. Carl Hastings, Reliv vice chairman and...

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...

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...
