Evaluating Evolutionary Rates Could Shed Light Into Functions of Uncharacterized Genes
February 8, 2013 — Genes that have roles in the same biological pathways change their rate of evolution in parallel, a finding that could be used to discover their functions, said a researcher. Humans have nearly ... > full story -
Histone Modification Controls Development: Chemical Tags on Histones Regulate Gene Activity
February 8, 2013 — Every gene in the nucleus of an animal or plant cell is packaged into a beads-on-a-string like structure called nucleosomes: the DNA of the gene forms the string and a complex of proteins called ... > full story -
Protein Paves the Way for Correct Stem Cell Differentiation
February 7, 2013 — A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. New research has ... > full story -
For Drug Makers, New 3-D Control Opens Wealth of Options
February 7, 2013 — Scientists have demonstrated a new, highly versatile approach for quickly assembling drug-like compounds, establishing a broad new route to drug discovery and medical ... > full story -
Translation Error Tracked in the Brain of Dementia Patients: Scientists Identify Enigmatic Aggregates Linked to Neurodegenerative Diseases
February 7, 2013 — In certain dementias silent areas of the genetic code are translated into highly unusual proteins by mistake. The proteins that have now been identified shouldn't actually ... > full story -
Key Protein Revealed as Trigger for Stem Cell Development
February 7, 2013 — A natural trigger that enables stem cells to become any cell type in the body has been discovered by scientists. Researchers have identified a protein that kick-starts the process by which stem cells ... > full story -
Study Identifies Liver Gene That Regulates Cholesterol and Fat Blood Levels
February 7, 2013 — Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in ... > full story -
Zinc Helps Against Infection by Tapping Brakes in Immune Response
February 7, 2013 — New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even ... > full story -
'Zombie' Cells May Outperform Live Ones as Catalysts and Conductors
February 7, 2013 — A simple technique uses silica to coat a living cell both inside and outside. The process forms a near-perfect replica of the cell's structure, down to the tiniest organelle. The resulting model, ... > full story -
New Compound Protects Heart Cells During and After Attack, Animal Study Suggests
February 7, 2013 — Using two different compounds they developed, scientists have been able to show in animal models that inhibiting a specific enzyme protects heart cells and surrounding tissue against serious damage ... > full story
