The circadian clocks that control and influence dozens of basic biological processes have an unexpected "snooze button" that helps cells adapt to changes in their environment. A study by Vanderbilt University researchers published online Feb. 17 by the journal Nature provides compelling new evidence that at least some species can alter the way that their biological clocks function by using different "synonyms" that exist in the genetic code. "This provides organisms with a novel and...

Genes relocated from their correct position in the nucleus cause them to malfunction and this may lead to the heart, blood vessels and muscles breaking down.Singapore, Feb 8, 2013 - (ACN Newswire) - Scientists from Singapore and Germany have identified that the proteins lamin A (Lmna) and lamin B receptor (Lbr) are essential for holding silent genes in their correct position at the edge of the nucleus, in the form of heterochromatin(1). A deviation from their normal position will cause the...

Research by UC Riverside plant pathologists is the first to show that RNA silencing regulates plant defense against the notorious Phytophthora pathogens When a pathogen attacks a plant, infection usually follows after the plant´s immune system is compromised. A team of researchers at the University of California, Riverside focused on Phytophthora, the pathogen that triggered the Irish Famine of the 19th century, and deciphered how it succeeded in crippling the potato plant´s...

Studies suggest new approach to treating HIV A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, when it reads the code, switches from repairing the DNA to chopping it up into unusable pieces. The researchers, who report the find in the Jan. 21 early...

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing themselves from stagnation or death. The study appears in the January 21st issue of The Journal of Cell Biology. The BRCA1 protein helps to mend double-strand DNA breaks by promoting homologous recombination. Without it, cells can amass broken, jumbled, and fused...

A new metabolic engineering tool that allows fine control of gene expression level by employing synthetic small regulatory RNAs was developed to efficiently construct microbial cell factories producing desired chemicals and materials Biotechnologists have been working hard to address the climate change and limited fossil resource issues through the development of sustainable processes for the production of chemicals, fuels and materials from renewable non-food biomass. One promising...
