About
microRNAs (miRNAs) are small, noncoding RNAs that may regulate more than half of human genes, yet the molecular mechanism of miRNA-mediated repression remains obscure. Using a cell-free assay of miRNA activity, we show that miRNA-targeted mRNAs are enriched for components of the 40S, but not 60S ribosomal subunit. Additionally, a molecular toeprint of 18 nucleotides 3' relative to the start codon, consistent with nucleotide protection by 40S ribosomal subunits, is enriched on miRNA-targeted mRNAs. Our results suggest that miRNAs repress translation initiation in a cell-free system by preventing 60S ribosomal subunit joining to 40S subunits positioned at the start codon.

  1. 1

    How does the author's investigation into the hidden mechanisms of microRNAs mirror our own human desire to understand the unseen forces that shape our lives and health?

  2. 2

    In a field as microscopic and complex as melanoma research, how does Yanez make the invisible machinery of cellular repression feel immediate and consequential to the reader?

  3. 3

    The text describes how translation initiation factors prevent the 60S subunit from joining the 40S subunit. Have you ever experienced a moment in your personal or professional life where a vital final connection was blocked just as something important was about to begin?
