A new level of variation in messenger RNAs exposed Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers at EMBL have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings, published today in...

Scientists have adopted a novel laboratory approach for determining the effect of genetic variation on the efficiency of the biological process that translates a gene's DNA sequence into a protein, such as hemoglobin, according to a presentation, Nov. 6, at the American Society of Human Genetics 2012 meeting in San Francisco. In the 0.1% of the DNA that differs between any two individuals, scientists search for the biological mechanisms underlying human genetic differences, including...

Targeted 'negative ASOs' cause missplicing and pathogenesis, providing unique window on disease progression A team led by scientists at Cold Spring Harbor Laboratory (CSHL) has developed a new way of making animal models for a broad class of human genetic diseases — those with pathology caused by errors in the splicing of RNA messages copied from genes. To date, about 6,000 such RNA "editing" errors have been found in various human illnesses, ranging from neurodegenerative disorders...

Structural analysis opens the way to new anti-influenza drugs Researchers at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, have determined the detailed 3-dimensional structure of part of the flu virus' RNA polymerase, an enzyme that is crucial for influenza virus replication. This important finding is published today in PLoS Pathogens. The research was done on the 2009 pandemic influenza strain but it will help scientists to design innovative drugs against all the...

MicroRNAs (miRNAs) are endogenously encoded RNAs that regulate the stability or translation of mRNA molecules, and emerging research suggests that they have diverse roles in normal physiology and disease. In this issue, two groups investigated the role of the predominant liver miRNA, miR-122. Ann-Ping Tsou and colleagues from National Yang-Ming University in Taiwan, and a team led by Kalpana Ghoshal, from Ohio State University generated mouse models of MiR-122 loss of function, and determined...


Word of the Day
jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
