Abstract

J. Neurochem. (2012) 120, 230–238. Brain‐derived neurotrophic factor (BDNF) is required for efficient skeletal‐muscle regeneration and perturbing its expression causes abnormalities in the proliferation and differentiation of skeletal muscle cells. In this study, we investigated the mechanism of BDNF suppression that occurs during myogenic differentiation. BDNF is expressed at the mRNA level as two isoforms that differ in the length of their 3′UTRs as a result of alternative cleavage and polyadenylation. Sequence analysis revealed the presence of three miR‐206 target sites in the long BDNF 3′UTR (BDNF‐L), whereas only one site was found in the short mRNA BDNF 3′UTR (BDNF‐S). miR‐206 is known to regulate the differentiation of C2C12 myoblasts and its expression is induced during the transition from myoblasts to myotubes. We thus examined whether miR‐206‐mediated suppression is responsible for the expression pattern of BDNF during myogenic differentiation. BDNF‐L was suppressed to a greater extent than BDNF‐S during differentiation of C2C12 myoblasts. Transfection of a miR‐206 precursor decreased activity of reporters representative of the BDNF‐L 3′UTR, but not BDNF‐S 3′UTR, and repressed endogenous BDNF mRNA levels. This suppression was found to be dependent on the presence of multiple miR‐206 target sites in the BDNF‐L 3′UTR. Conversely, suppression of miR‐206 levels resulted in de‐repression of BDNF 3′UTR reporter activity and increased endogenous BDNF‐L mRNA levels. A receptor for BDNF, p75 NTR, was also suppressed during differentiation and in response to miR‐206, but this appeared to not be entirely mediated via a miR‐206 target site its 3′UTR. Based on these observations, BDNF represents a novel target through which miR‐206 controls the initiation and maintenance of the differentiated state of muscle cells. These results further suggest that miR‐206 might play a role in regulating retrograde signaling of BDNF at the neuromuscular junction.

  • Stem cell quiescence is controlled at least in part by mechanisms that alter 3' UTR length and thus susceptibility to miRNA regulation.

    “the importance of transcript 3′ UTRs as targets for miRNAs suggests that stem cell quiescence is controlled, at least in part, by mechanisms that alter 3′ UTR length and thus the susceptibility to regulation by miRNAs92–95.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
