Model unravels rules that govern how genes are switched on and off

For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off.

Dormant stem cells for emergencies

Many specialized cells, such as in the skin, intestinal mucosa or blood, have a lifespan of only a few days.

Fruit flies provide better understanding of human heart disease

Researchers at the Burnham Institute for Medical Research have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function.

Foxm1 gene mutation may cause immature lungs in newborns

Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing.

What are 'orphan' genes needed for?

Closely related animal species share most of their genes and look almost identical.

First comprehensive genetic blueprint of a forming mammalian organ

Part of an international consortium sponsored by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), a research team led by Cincinnati Children's Hospital Medical Center reports the creation of a detailed genome-based atlas for understanding healthy and abnormal kidney development and disease.

Scientists show how "junk" DNA may be a major driver for evolution

In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.

Universal gene signaling mechanism identified by UB molecular researchers

A novel gene signaling mechanism that controls whether a stem cell develops into its destined tissue or fails to differentiate and becomes cancer has been identified by researchers in the multi-laboratory Molecular and Structural Neurobiology and Gene Therapy Program based at the University at Buffalo.

Newly discovered molecular switch creates new path to study birth defects and cancer

Researchers have discovered a central molecular switch in fruit fly embryos that opens new avenues for studying the causes of birth defects and cancer in humans.

How short RNAs influence many proteins

During the last decade, microRNAs have emerged somewhat surprisingly as key players in the way genes are regulated. These short snippets of RNA do their work by interacting with messenger RNAs, which act as blueprints for protein creation.

Suprising finding on aging

Age may not be rust after all. Specific genetic instructions drive aging in worms, report researchers at the Stanford University School of Medicine. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage akin to rust, and implies science might eventually halt or even reverse the ravages of age.

Enzyme plays key role in cell fate

The road to death or differentiation follows a similar course in embryonic stem cells, said researchers at Baylor College of Medicine in Houston in a report that appears online today in the journal Cell Stem Cell.

Timer genes control brain size

Experiments using fruit flies have helped a team at the MRC National Institute for Medical Research to identify genes that control how large the developing brain becomes.

NCI scientists visualize gene regulation in living cells

A research team led by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), has applied advanced imaging methods and computer simulations to be able to glance at the regulation of a cancer-related gene in a living cell. They found that the efficiency with which the components of the cell's gene reading machinery come together has an impact on gene expression, the process by which a gene translates its information into a new protein. The findings, published in the May 23, 2008 issue of Molecular Cell, shed new light on the means by which living cells regulate gene activity.

Plant flavonoid luteolin reduces inflammatory response in the brain

Researchers at the University of Illinois report this week that a plant compound found in abundance in celery and green peppers can disrupt a key component of the inflammatory response in the brain. The findings have implications for research on aging and diseases such as Alzheimer's and multiple sclerosis.

Genetic tag team orchestrates the cell cycle

By surveying the activity of thousands of genes at several different time points, researchers at the Duke Institute for Genome Sciences & Policy have uncovered new evidence that a network of influential genes act as a kind of genetic tag team to orchestrate one of the most fundamental aspects of all life: the cell cycle.

FGFR2 gene increases susceptibility to breast cancer

Much work has been done to identify genetic variations that predispose women to breast cancer. Previous work showed that variants in the gene called fibroblast growth factor receptor 2 (FGFR2) were associated with increased risk of the disease, but how these variants translated into increased risk was unknown.

Discovery of a critical early player in the path that turns cells to fat

Given that obesity - defined as an excess amount of body fat relative to lean body mass - is a major health concern in the United States and an increasing problem in the developing world, such a fuller understanding of the molecular processes governing fat tissue formation could ultimately hold clinical importance, according to the researchers.

More efficient gene targeting improves prospects for gene therapy

The Nobel prize-winning MRC scientist Sir Aaron Klug and a team from an American company, Sangamo BioSciences, have announced a new way to target genes that may revolutionise medical research and pave the way for new treatments.

Molecular alliance that sustains embryonic stem cell state

One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of a molecular alliance between a specific group of key proteins known as transcription factors, a research team led by the Genome Institute of Singapore (GIS) under the Agency for Science, Technology and Research (A*STAR) reports in the current issue of Nature Cell Biology.
