  1. Non-microRNA binding competitively inhibits LIN28 regulation.

    Cell reports · 2021 · 36(6): 109517

    RNA binding protein (RBP) expression is finite. For RBPs that are vastly outnumbered by their potential target sites, a simple competition for binding can set the magnitude of post-transcriptional control. Here, we show that LIN28, best known for its direct …

    PMID 34380031 DOI ↗

  2. A Transcriptome-wide Translational Program Defined by LIN28B Expression Level.

    Molecular cell · 2019 · 73(2): 304-313.e3

    LIN28 RNA binding proteins are dynamically expressed throughout mammalian development and during disease. However, it remains unclear how changes in LIN28 expression define patterns of post-transcriptional gene regulation. Here we show that LIN28 expression level is a key variable that …

  3. The Period protein homolog LIN-42 negatively regulates microRNA biogenesis in C. elegans.

    Developmental biology · 2014 · 390(2): 126-35

    MicroRNAs (miRNAs) are small RNAs that post-transcriptionally regulate gene expression in many multicellular organisms. They are encoded in the genome and transcribed into primary (pri-) miRNAs before two processing steps that ultimately produce the mature miRNA. In order to generate …

    PMID 24699545 DOI ↗

  4. Functional genomic analysis of the let-7 regulatory network in Caenorhabditis elegans.

    PLoS genetics · 2013 · 9(3): e1003353

    The let-7 microRNA (miRNA) regulates cellular differentiation across many animal species. Loss of let-7 activity causes abnormal development in Caenorhabditis elegans and unchecked cellular proliferation in human cells, which contributes to tumorigenesis. These defects are due to improper expression of …

    PMID 23516374 DOI ↗

  5. LIN28 binds messenger RNAs at GGAGA motifs and regulates splicing factor abundance.

    Molecular cell · 2012 · 48(2): 195-206

    LIN28 is a conserved RNA-binding protein implicated in pluripotency, reprogramming, and oncogenesis. It was previously shown to act primarily by blocking let-7 microRNA (miRNA) biogenesis, but here we elucidate distinct roles of LIN28 regulation via its direct messenger RNA (mRNA) …

    PMID 22959275 DOI ↗

  6. LIN-28 co-transcriptionally binds primary let-7 to regulate miRNA maturation in Caenorhabditis elegans.

    Nature structural & molecular biology · 2011 · 18(3): 302-8

    The highly conserved let-7 microRNA (miRNA) regulates developmental pathways across animal phyla. Mis-expression of let-7 causes lethality in C. elegans and has been associated with several human diseases. We show that timing of let-7 expression in developing worms is under …
