University of Alberta researchers find new cause of blindness
The scientific community is just starting to appreciate the importance of pH regulation in normal vision.   view more (2007-09-05)

Evolution is driven by gene regulation
It is not just what's in your genes, it's how you turn them on that accounts for the difference between species - at least in yeast - according to a report by Yale researchers in this week's issue of Science.   view more (2007-08-10)

Free shopping in a virtual bazaar of gene regulation data
An international team has opened a virtual bazaar, called PAZAR, which allows biologists to share information about gene regulation through individually managed 'boutiques' (data collections).   view more (2007-10-04)

Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.   view more (2008-02-28)

Identification of Functional SNPs - Advances in Determining Genetic Susceptibility to Disease
Researchers at Oxford University's Wellcome Trust Centre for Human Genetics have developed a methodology to evaluate concurrently the functional significance of the millions of non-coding polymorphisms that exist in the human genome. Ultimately, this method will aid the progress in determining... view more (2003-04-07)

Stringent regulation of traditional medicines is urgently needed
Traditional Chinese medicines for slimming still cause health problems and stringent regulation is urgently needed, according to a letter in this week's BMJ. Researchers at Southend Hospital in Essex analysed several slimming preparations and the urine of several patients who had been attending a... view more (2002-03-13)

Panic attacks tied to breathing
Panic disorder can be tied to disturbances in the regulation of breathing. A dissertation from the Sahlgrenska Academy at Göteborg University in Sweden shows that the effect of serotonin preparations in attacks of panic anxiety might be due to their influence on breathing.   view more (2002-12-20)

The benefits of social contact
Have you ever wondered why people surrounded by friends or family appear happier and healthier?   view more (2007-05-18)

Researchers discover new form of cancer gene regulation
The Quaking gene, first described as a mutation in mice that causes rapid tremor, is thought to suppress tumor formation and protect humans from cancer.   view more (2005-11-08)

Turn-ons and turn-offs for neurons
Our brain consists of billions of nerve cells enabling to learn, remember and reason. Every time we think and experience, touch, smell or fear, millions of neurons in our brain becomes active.   view more (2007-06-20)

Most human-chimp differences due to gene regulation - not genes
The vast differences between humans and chimpanzees are due more to changes in gene regulation than differences in individual genes themselves, researchers from Yale, the University of Chicago, and the Hall Institute in Parkville, Victoria, Australia, argue in the 9 March 2006 issue of the journal... view more (2006-03-09)

Unravelling new complexity in the genome
A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans.   view more (2007-08-14)

Isolation of a new gene family essential for early development
Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute sig-nificantly to the understanding of... view more (2007-08-23)

Making memories that last a lifetime
Neurobiologists have discovered a mechanism by which the constantly changing brain retains memories—from that dog bite to that first kiss. They have found that the brain co-opts the same machinery by which cells stably alter their genes to specialize during embryonic development.   view more (2007-03-15)

Fitting in: Newly evolved genes adopt a variety of strategies to remain in the gene pool
When Mother Nature creates an identical copy of a gene in an organism's genome, the duplicated copy is usually deleted, inactivated, or otherwise rendered nonfunctional in order to prevent genetic redundancy and to preserve biological homeostasis.   view more (2005-10-03)

Search for the 'on' switches may reveal genetic role in development and disease
A new resource that identifies regions of the human genome that regulate gene expression may help scientists learn about and develop treatments for a number of human diseases, according to researchers at Duke's Institute for Genome Sciences & Policy (IGSP).   view more (2008-01-25)

Teamwork between 2 key proteins necessary for normal development and regulation of red blood cells
Virginia Commonwealth University researchers studying hemoglobin genes, mutations of which play a role in genetic blood disorders like sickle cell anemia and beta-thalassemia, have identified two proteins that are responsible for regulating overlapping groups of genes during the development of red... view more (2007-08-07)

Epigenetic research uncovers new targets for modification enzymes
Enzymes regulating genetic expression can be just as important as the genome itself, increasing evidence shows. The expanding field of epigenetics focuses on the multiple influences on DNA and surrounding molecules that determine whether genes are turned on or off during development and disease... view more (2008-04-28)

How nature tinkers with the cellular clock
The life of a cell is all about growing and dividing at the right time. That is why the cell cycle is one of the most tightly regulated cellular processes.   view more (2006-09-28)

First gene therapy for heart failure offered at NewYork-Presbyterian/Columbia
Could injecting a gene into a patient with severe heart failure reverse their disabling and life-threatening condition? Physician-scientists are setting out to answer that question in a first-ever clinical trial of gene therapy to treat severe heart failure.   view more (2008-06-19)

Study finds value in 'junk' DNA
For about 15 years, scientists have known that certain "junk" DNA -- repetitive DNA segments previously thought to have no function -- could evolve into exons, which are the building blocks for protein-coding genes in higher organisms like animals and plants.   view more (2008-10-17)

Rushing fireball developed its own form of sugar digestion
Microbiologists from Wageningen have discovered a strange form of digestion in an exotic microorganism. The rushing fireball, Latin name Pyrococcus furiosus, has reinvented the wheel for several steps of sugar digestion. Pyrococcus furiosus, which was discovered 15 years ago on an Italian volcanic... view more (2002-04-18)

Effects of aging in stem cells
There is little disagreement that the body's maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why.   view more (2007-07-24)

Gene expression pattern could lead to improved treatment of pediatric septic shock
A consortium of researchers headed by Cincinnati Children's Hospital Medical Center has discovered a gene expression pattern that could lead to improved diagnosis and treatment of pediatric septic shock - still a serious public health problem despite today's potent antibiotics and pediatric... view more (2007-07-27)

A brainy idea 25 years in the making
A discovery made 25 years ago about how the brain controls blood pressure regulation is only now being explored with the help of scientists from the Howard Florey Institute.   view more (2007-10-04)
