Improved statistical tools reveal many linked loci
An innovative new statistical method, described in the open-access journal PLoS Biology, streamlines the computation required to identify all the potential locations in the genome that influence a particular physical trait, or phenotype. view more (2005-07-26)
High cholesterol diets modify gene expression in atherosclerosis
Scientists from the department of Biochemistry and Molecular Biology 1 of the University of Granada (Universidad de Granada) have proven that a high cholesterol diet causes changes in gene expression of chicken aortic smooth muscle cells at the early stages of an experimental atherosclerosis. view more (2007-06-13)
A new key to detecting deadly aortic aneurysms
Yale scientists have discovered a way to use a simple blood test that may accurately detect thoracic aneurysm disease (TAA), which gives little warning and is almost always fatal if untreated. view more (2007-10-25)
Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE. view more (2008-10-06)
Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed
During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. view more (2007-12-10)
Boston Univeristy bioengineers devise 'dimmer swith' to regulate gene expression in mammal cells
Three Boston University biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene's function. view more (2007-07-27)
Van Andel Institute Study Rules Out Transcriptional Coactivators as Useful Herpes Antiviral Drug Targets
Researchers at Van Andel Research Institute (VARI) have determined that the herpes simplex virus type 1 (HSV-1) does not require transcriptional coactivators for viral gene expression early in the infection process. The finding is significant in determining that, in contradiction to earlier models, chemical inhibitors of these cellular proteins... view more... (2009-03-26)
MRI: A window to genetic properties of brain tumors
Doctors diagnose and prescribe treatment for brain tumors by studying, under a microscope, tumor tissue and cell samples obtained through invasive biopsy or surgery. view more (2008-03-25)
Gene expression levels may reveal stage of Huntington's disease
A survey of the genome of patients with Huntington's Disease (HD) has identified potential markers of the progression of this devastating neurological disorder. view more (2005-08-17)
Scientists find clue to mechanisms of gene signaling and regulation
Scientists have discovered a pattern in the DNA sequence of the mouse genome that may play a fundamental part in the way DNA molecules regulate gene expression. view more (2007-08-23)
Computation to unravel how genes are regulated and shed light on how cells become different
A closer alliance between computational and experimental researchers is needed to make progress towards one of biology's most challenging goals, understanding how epigenetic marks contribute to regulation of gene expression. view more (2008-04-11)
UT Southwestern researchers identify new targets for RNAs that regulate genes
Tiny strands of genetic material called RNA - a chemical cousin of DNA - are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease. view more (2008-07-07)
Divergent life history shapes gene expression in brains of salmon
Scientists working with salmon have found that gene expression in the brain can differ significantly among members of a species with different life histories. view more (2005-07-21)
Probiotic bacteria can induce monocyte-derived dendritic cells maturation?
Probiotic bacteria are widely used to relieve the symptoms of many disorders such as inflammatory bowel syndrome, diarrhea, and allergies. Probiotic mixtures have also been found to reduce the symptoms of diarrhea. view more (2008-09-25)
Predicting acute GVHD by gene expression could improve liver stem cell transplant outcomes
Many cell transplants involve the use of stem cells from another human being (known as an allograft), which raises the major concern of the potential for acute graft-versus-host disease (GVHD). view more (2008-07-21)
Depression model leaves mice with molecular scar
In addition to triggering a depression-like social withdrawal syndrome, repeated defeat by dominant animals leaves a mouse with an enduring "molecular scar" in its brain that could help to explain why depression is so difficult to cure. view more (2006-03-01)
Fox Chase Researchers Uncover One Force Behind the MYC Oncogene in Many Cancers
DLX5, a gene crucial for embryonic development, promotes cancer by activating the expression of the known oncogene, MYC, according to researchers from Fox Chase Cancer Center. view more (2009-07-29)
Protein protects anti-cancer gene from chemical shutdown
A protein that is largely absent in one type of skin cancer protects an important gene in a cell's defense against harmful mutations from being silenced. view more (2007-07-20)
A novel marker of colorectal carcinoma
The colorectal cancer is thought to be resulted from a combination of environmental factors, diet, lifestyle, chronic inflammation and accumulation of specific genetic alterations. view more (2009-05-22)
Understanding the Noxious cause of Lou Gehrig's disease
There is no known cure for amyotrophic lateral sclerosis (ALS), often known as Lou Gehrig disease and motor neuron disease. view more (2007-09-14)
