    MicroRNA-mediated repression of nonsense mRNAs

    Ya Zhao et al.
    microRNAs can serve as a surveillance system to repress nonsense mRNAs by recognizing miRNA-responsive elements in the open reading frame region downstream of the premature termination codon.

    Decreased microRNA levels lead to deleterious increases in neuronal M2 muscarinic receptors in Spinal Muscular Atrophy models

    Patrick J O'Hern et al.
    In invertebrate and vertebrate models of Spinal Muscular Atrophy, diminished SMN protein causes Gemin3-dependent decreases in microRNA function, leading to upregulated M2 muscarinic receptor and deleterious consequences.

    microRNA-1 regulates sarcomere formation and suppresses smooth muscle gene expression in the mammalian heart

    Amy Heidersbach et al.
    microRNA-1 plays an essential role in the development and functioning of the heart by ensuring that genes for striated, rather than smooth, muscle are expressed there.

    Decoupling the impact of microRNAs on translational repression versus RNA degradation in embryonic stem cells

    Jacob W Freimer et al.
    The deletion of Ddx6 results in the translational upregulation, but not transcript stabilization, of microRNA targets in embryonic stem cells while largely phenocopying the overall impact of global microRNA loss.

    Cotranslational microRNA mediated messenger RNA destabilization

    Trinh To Tat et al.
    MicroRNAs stimulate the decay of targeted mRNAs while they are associated with translating ribosomes.

    MicroRNA-203 represses selection and expansion of oncogenic Hras transformed tumor initiating cells

    Kent Riemondy et al.
    Inhibition of microRNA-203 by oncogenic HRas mutations promotes skin cancer initiation.

    MicroRNA-146a acts as a guardian of the quality and longevity of hematopoietic stem cells in mice

    Jimmy L Zhao et al.
    Chronic and excessive inflammation can lead to exhaustion of the supply of hematopoietic stem cells and to myeloid malignancies in mice, mimicking important aspects of the myelodysplastic syndrome found in humans.

    Y-box protein 1 is required to sort microRNAs into exosomes in cells and in a cell-free reaction

    Matthew J Shurtleff et al.
    A cell-free reaction that reconstitutes the selective sorting of a miRNA into exosomes reveals an RNA-binding protein, YBX1, as a critical sorting factor.

    Water-mediated recognition of t1-adenosine anchors Argonaute2 to microRNA targets

    Nicole T Schirle et al.
    Argonaute proteins directly contact adenosine nucleotides in some miRNA target sites, leading to enhanced repression of the target mRNA.
