Translation Profiling +/- miR-124


ABSTRACT: Ribosome Occupancy Experiments: for these experiments Channel 1 is amplified RNA (aRNA) from mRNA unbound to any ribosomes. Channel 2 is aRNA from mRNA associated with ribosomes. Ribosome Density Experiments: for these experiments Channel 1 is amplified RNA (aRNA) from mRNA present in the light fractions of the polysome. Channel 2 is aRNA from mRNA associated with ribosomes deep in the polysome. Experiments are biological replicates of ribosome occupancy and density 12 hours post mock transfection or miR-124 transfection.

MicroRNAs (miRNAs) regulate gene expression posttranscriptionally by interfering with a target mRNA's translation, stability, or both. We sought to dissect the respective contributions of translational inhibition and mRNA decay to microRNA regulation. We identified direct targets of a specific miRNA, miR-124, by virtue of their association with Argonaute proteins, core components of miRNA effector complexes, in response to miR-124 transfection in human tissue culture cells. In parallel, we asses  ...[more]
