Researchers at the Stanford University School of Medicine have identified a new group of proteins involved in determining the life span of laboratory roundworms. Blocking the expression of one member of the group can extend the worm's life span by up to 30 percent. Because the proteins work in the worms' reproductive systems, the research represents yet another intriguing link between longevity and fertility. In particular, the researchers showed that the proteins are involved in epigenetics...

Findings help illuminate biochemical mechanisms that determine stem cell function and fate Human embryonic stem cells (hESCs) possess remarkable properties of self-renewal and pluripotency, the ability to become almost any kind of cell within the body. And yet they share the same genome or set of genes with lineage-committed cells, cells fated to be or do one thing. Scientists have long suspected that the distinct properties of different cells were attributable to their particular epigenomes...

New on-off switches: SUMO protein silences developmental genes, SNP2 snips SUMO to allow gene expression HOUSTON "“ Deleting a gene in mouse embryos caused cardiac defects and early death, leading researchers to identify a mechanism that turns developmental genes off and on as an embryo matures, a team led by a scientist at The University of Texas M. D. Anderson Cancer Center reported today in Molecular Cell. "Our study focused on regulation of two genes that are critical to the healthy...

A paper published online today in Molecular Cell proposes that Methyl CpG binding protein 2 (MeCP2) impacts the entire genome in neurons, rather than acting as a regulator of specific genes. Mutations in MeCP2 cause the autism spectrum disorder Rett Syndrome as well as some cases of neuropsychiatric problems including autism, schizophrenia and learning disabilities. The discovery of MeCP2's global reach was made in the laboratory of Adrian Bird, Ph.D. of the University of Edinburgh. Bird's...

Discovery could lead to new drugs for combating spread of deadly disease Malaria remains one of the most deadly infectious diseases. Yet, how Plasmodium, the malaria parasite, regulates its infectious cycle has remained an enigma despite decades of rigorous research. But now a team led by a cell biologist at the University of California, Riverside has identified a mechanism by which Plasmodium intensively replicates itself in human blood to spread the disease. "If this mechanism can be...

A viral infection is like an uninvited, tenacious houseguest in the cell, using a range of tricks to prevent its eviction. Researchers at the Salk Institute for Biological Studies have identified one of the key proteins allowing herpes simplex virus (HSV) DNA to fly under the radar of their hosts' involuntary hospitality. Their findings, to be published in a forthcoming issue of The EMBO Journal, reveal one of the tactics that HSV employs in order to overcome its hosts' defenses and may...

Plants are incredibly temperature sensitive and can perceive changes of as little as one degree Celsius. Now, a report in the January 8th issue of the journal Cell, a Cell Press publication, shows how they not only 'feel' the temperature rise, but also coordinate an appropriate response -- activating hundreds of genes and deactivating others; it turns out it's all about the way that their DNA is packaged. The findings may help to explain how plants will respond in the face of climate change...

Like a child awaiting the arrival of Christmas, embryonic stem cells exist in a state of permanent anticipation. They must balance the ability to quickly become more specialized cell types with the cellular chaos that could occur should they act too early (stop shaking those presents, kids!). Researchers at the Stanford University School of Medicine have now identified a critical component, called Jarid2, of this delicate balancing act "” one that both recruits other regulatory proteins...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
