Biologists develop genome-wide map of miRNA-mRNA interactions
Researchers at New York University's Center for Comparative Functional Genomics and the University of California, Berkeley have used computational analyses to predict a genome-wide map of microRNA (miRNA) targets in the animal model organism, Caenorhabditis elegans (C. elegans). MicroRNAs bind to messenger RNA (mRNA) in a specific section, called 3'UTR, and are known to regulate them. Parts of th...miRNA-mediated silencing of mRNAs
Dr. Elisa Izaurrralde and colleagues (EMBL; Max-Planck-Institute for Developmental Biology-Tuebingen) provide new mechanistic insight into gene silencing by miRNAs . .. .. Dr. Izaurralde and colleagues demonstrate that the P-body protein, GW182, interacts with the miRNA effector Argonaute proteins as well as mRNA degradation e...Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription
The distribution of the four nucleotides along the DNA sequence encodes the genetic information in living systems. However, do nucleic acids possess other attributes that contribute to their biological functions? Recent work of a team led by Stoyno Stoynov, working at the Bulgarian Academy of Sciences, suggests that thermodynamic stability of DNA/DNA and RNA/DNA duplexes influences mRNA transcrip...
