  1. ...of duplication (Fig. 2C). MicroRNAs (miRNAs) are short, noncoding RNAs that fine-tune gene dosage by pairing to the 3′ untranslated region and lowering target mRNA levels (Bartel 2009). Conserved targeting by miRNAs is a feature of genes sensitive to changes in gene dosage, particularly to overexpression (Naqvi...
  2. ...Chromosome inactivation (XCI) in females, but some Y-linked genes were retained during the course of sex chromosome evolution, and many X-linked genes did not become subject to XCI. We reconstructed gene-by-gene dosage sensitivities on the ancestral autosomes through phylogenetic analysis of microRNA (mi...
  3. ...in evolutionary biology. In addition to protein sequence changes, gene expression alterations due to regulatory mutations are thought to underlie many or even most phenotypic innovations (King and Wilson 1975). MicroRNAs (miRNAs) are short (approximately 22 nucleotides) noncoding RNA molecules that bind...
  4. ...by microRNAs (miRNAs), small regulatory RNAs that act as sequence-specific repressors of gene expression (Bartel 2018). A miRNA might specifically target EIF1AX, limiting its expression level in these tissues. When we searched the 3′ untranslated region (3′ UTR) of EIF1AX (Methods), the miRNA target site...
