Abstract

The proper functions of cortical circuits are dependent upon both appropriate neuronal subtype specification and their maturation to receive appropriate signaling. These events establish a balanced circuit that is important for learning, memory, emotion, and complex motor behaviors. Recent research points to mRNA metabolism as a key regulator of this development and maturation process. Hu antigen D (HuD), an RNA-binding protein, has been implicated in the establishment of neuronal identity and neurite outgrowth in vitro. Therefore, we investigated the role of HuD loss of function on neuron specification and dendritogenesis in vivo using a mouse model. We found that loss of HuD early in development results in a defective early dendritic overgrowth phase and pervasive deficits in neuron specification in the lower neocortical layers and defects in dendritogenesis in the CA3 region of the hippocampus. Subsequent behavioral analysis revealed a deficit in performance of a hippocampus-dependent task: the Morris water maze. Further,HuD knock-out (KO) mice exhibited lower levels of anxiety than their wild-type counterparts and were overall less active. Last, we found that HuD KO mice are more susceptible to auditory-induced seizures, often resulting in death. Our findings suggest that HuD is necessary for the establishment of neocortical and hippocampal circuitry and is critical for their function.

  • ELAVL4 expression decreases self-renewal of neural progenitor cells and promotes deep-layer glutamatergic neuronal differentiation.

    “ELAVL4 expression decreases self-renewal of neural progenitor cells and promotes deep-layer glutamatergic neuronal differentiation (Akamatsu et al., 2005; DeBoer et al., 2014; Popovitchenko et al., 2020).”

    From ELAVL4, splicing, and glutamatergic dysfunction precede neuron loss in MAPT mutation cerebral organoids (2021) · cites this paper as DeBoer et al., 2014

    The Results section, “HuD is critical for the balanced expression of Tle4 in lower layer neocortical neurons” (page unavailable), reports fewer Tle4-positive lower-layer neurons after HuD deletion and suggests a role in their specification and/or maintenance. That supports a connection to deep-layer neuronal identity, but does not establish that ELAVL4 expression promotes differentiation specifically. Our copy does not report that ELAVL4 decreases neural progenitor self-renewal. (LLM, conf=0.86)

  • ELAVL4 is selectively expressed in neuronal populations vulnerable to cell death in tau-V337M organoids.

    “ELAVL4 is selectively expressed in neuronal populations vulnerable to cell death in tau-V337M organoids, consistent with its reported expression in the brain (Bronicki and Jasmin, 2013; DeBoer et al., 2014).”

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.
