Research also finds how RNA editing enzyme activity varies with temperature Because a function of RNA is to be translated as the genetic instructions for the protein-making machinery of cells, RNA editing is the body's way of fine-tuning the proteins it produces, allowing us to adapt. The enzyme ADAR, which does this editing job in the nervous system of creatures ranging from mice to men, even edits itself. In a new study that examined the self-editing process and locked it down at two...

An international team led by the University of Melbourne Australia, has found that increasing a specific protein in muscles could help treat Duchenne muscular dystrophy (DMD), a severe and progressive muscle wasting disease that affects young boys. Approximately one in every 3,500 boys worldwide is afflicted with DMD. There is no cure for the disease which causes muscle fragility, spinal curvature and premature death. Results from the studies published in Nature today showed that by...

Cardiomyopathy comprises a deterioration of the heart muscle that affects the organ's ability to efficiently pump blood through the body. Previously researchers have tied forms of the disease to the alternative splicing of titin, a giant protein that determines the structure and biomechanical properties of the heart, but the molecular mechanism remained unknown. Professor Michael Gotthardt and Professor Norbert Hübner of the Max Delbrück Center for Molecular...

Few molecules are more interesting than DNA–except of course RNA. After two decades of research, that "other macromolecule" is no longer considered a mere messenger between glamorous DNA and protein-synthesizing machines. We now know that RNA has been leading a secret life, regulating gene expression and partnering with proteins to form catalytic ribonucleoprotein (RNP) complexes. One of those RNPs is telomerase, an enzyme that maintains chromosome integrity. In the March 25, 2012,...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
