Chloroplast f and m Thioredoxins Discovered in Nonphotosynthetic Tissues
Thioredoxins (TRXs) are a large family of small proteins that function in multiple metabolic processes in all living organisms. They are a good example of proteins that have diversified throughout evolution, probably from one ancestral protein that arose in ancient cyanobacteria. view more (2007-10-16)
Schizophrenia-linked gene keeps new adult brain cells under control
A gene with reported links to schizophrenia and other mood disorders plays a broader role in the brain than scientists had previously suspected. view more (2007-09-07)
Newly found sensing system enables certain bacteria to resist human immune defenses
Researchers at the National Institute of Allergy and Infectious Diseases (NIAID), a component of the National Institutes of Health, have discovered a survival mechanism in a common type of bacteria that can cause illness. view more (2007-06-08)
Mouse gene shows new mechanism behind cardiac infarction in man
A gene that, in different variants, increases or decreases the level of atherosclerosis has been identified in mice. The corresponding human gene has been shown to play a role in the development of myocardial infarction. The results of the study is published this week on Nature Genetics Online. view more (2005-03-08)
GEN highlights increasing use of digital gene expression profiling
A novel technique for carrying out gene-expression profiling is set to challenge the market dominance of the current, widely used methodology, reports Genetic Engineering & Biotechnology News (GEN). view more (2009-04-06)
Novel enzyme offers new look at male hormone regulation
For the second time in less than a year, University of North Carolina at Chapel Hill scientists have purified a novel protein and have shown it can alter gene activity by reversing a molecular modification previously thought permanent. view more (2006-05-08)
Gene fusion discovery may lead to improved prostate cancer test
A newly discovered gene fusion is highly expressed in a subset of prostate cancers, according to a study by researchers at Weill Cornell Medical College. view more (2009-04-10)
Shoots but no droop in longer-lasting plants
Limp lettuce and wilting roses could be a thing of the past, following the identification of a key plant gene by University scientists. The discovery could also improve food shelf life, and help speed up reforestation programmes. Plant scientists Professor Meyer and Dr Elena Zubko have identified the plant gene which produces a specific type of... view more... (2002-04-25)
Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline. view more (2007-05-14)
Researchers show how obesity causes breakdown in system which regulates appetite and weight
New research led by scientists at the Oregon National Primate Research Center demonstrates how obesity causes the breakdown of a brain system that regulates appetite. view more (2007-03-07)
Self-regulation game predicts kindergarten achievement
Early childhood development researchers have discovered that a simple, five-minute self-regulation game not only can predict end-of-year achievement in math, literacy and vocabulary, but also was associated with the equivalent of several months of additional learning in kindergarten. view more (2009-06-09)
UCSD Research May Lead to Targeted Treatment for Asthma Sufferers
The bronchial tubes of a patient with severe asthma can become scarred due to repeated episodes of allergic inflammation in the airways. The scarring results in blocked airways, excessive production of mucus, and shortness of breath. view more (2005-11-29)
Characterization of grapevine transposons furthers understanding of in vino variety
The grapevine (Vitis vinifera) is a widely cultivated crop that has been subjected to intensive breeding since the Neolithic period (from ~10,500 to ~6,000 years ago). The domestication of grapevine has undergone a selection for traits important for its cultivation and usage. view more (2008-09-03)
Ali Shilatifard and Colleagues Aim to Clarify the Definition of "Epigenetics"
Ali Shilatifard, Ph.D., Investigator, has joined with a team of colleagues to propose an operational definition of "Epigenetics" - a rapidly growing research field that investigates heritable alterations in gene expression caused by mechanisms other than changes in DNA sequence. view more (2009-04-02)
New breakthrough in global warming plant production
Researchers at the universities of Leicester and Oxford have made a discovery about plant growth which could potentially have an enormous impact on crop production as global warming increases. view more (2009-03-31)
'Destruct' triggers may be jammed in tumor cells, UF geneticists say
Tumor cells living in the cross hairs of radiation or chemotherapy may be able to escape death because their self-destruct mechanisms are jammed, say University of Florida scientists writing in a recent issue of Developmental Cell. view more (2008-05-01)
New cancer gene discovered
A new cancer gene has been discovered by a research group at the Sahlgrenska Academy. The gene causes an insidious form of glandular cancer usually in the head and neck and in women also in the breast. The discovery could lead to quicker and better diagnosis and more effective treatment. view more (2009-10-14)
Swallowing Accelerates The Heartbeat
Life depends on the cardiac activity, therefore researchers have been studying for centuries all factors that can affect it. Among other things, researchers have been interested in the heartbeat frequency regulation. The purpose of such investigation requires that the heart systematically broke the established rate, which is harmful for health.... view more... (2003-07-25)
Conquest of land began in shark genome
When the first four-legged animals sprouted fingers and toes, they took an ancient genetic recipe and simply extended the cooking time, say University of Florida scientists writing in Wednesday's issue of the journal PLoS ONE. view more (2007-08-15)
Researchers have discovered a gene that can block the spread of HIV
A team of researchers at the University of Alberta, including a scientist at the University of Pennsylvania, have discovered a gene that is able to block HIV, and thought to in turn prevent the onset of AIDS. view more (2008-02-29)
