ABSTRACT We probed an epigenetic regulatory path from small molecule to neuronal gene activation. Isoxazole small molecules triggered robust neuronal differentiation in adult neural stem cells, rapidly signaling to the neuronal genome via Ca(2+) influx. Ca(2+)-activated CaMK phosphorylated and mediated nuclear export of the MEF2 regulator HDAC5, thereby de-repressing neuronal genes. These results provide new tools to explore the epigenetic signaling circuitry specifying neuronal cell fate and new leads for neuro-regenerative drugs.

    ABSTRACT: Nervous system development relies on the generation of neurons, their differentiation and establishment of synaptic connections. These events exhibit remarkable plasticity and are regulated by many developmental cues. Here, we review the mechanisms of three classes of these cues: morphogenetic proteins, elec-trical activity, and the environment. We focus on second messenger dynamics and their role as integrators of the action of diverse cues, enabling plasticity in the process of neural development. V C 2014 Wiley Periodicals, Inc. Develop

    ABSTRACT: The Class IIa histone deacetylases HDAC4 and HDAC5 play a role in neuronal survival and behavioural adaptation in the CNS. Phosphorylation at 2/3 N-terminal sites promote their nuclear export. We investigated whether non-canonical signaling routes to Class IIa HDAC export exist due to their association with the co-repressor Silencing Mediator Of Retinoic And Thryoid Hormone Receptors (SMRT). We found that, while HDAC5 and HDAC4 mutants lacking their N-terminal phosphorylation sites (HDAC4(MUT) , HDAC5(MUT) ) are constitutively nuclear, co-expression with SMRT renders them exportable by signals that trigger SMRT export, such as synaptic activity, HDAC inhibition, and Brain Derived Neurotrophic Factor (BDNF) signaling. We found that SMRT's repression domain 3 (RD3) is critical for co-shuttling of HDAC5(MUT) , consistent with the role for this domain in Class IIa HDAC association. In the context of BDNF signalling, we found that HDAC5(WT) , which was more cytoplasmic than HDAC5(MUT) , accumulated in the nucleus after BDNF treatment. However, co-expression of SMRT blocked BDNF-induced HDAC5(WT) import in a RD3-dependent manner. In effect, SMRT-mediated HDAC5(WT) export was opposing the BDNF-induced HDAC5 nuclear accumulation observed in SMRT's absence. Thus, SMRT's presence may render Class IIa HDACs exportable by a wider range of signals than those which simply promote direct phosphorylation. © 2012 International Society for Neurochemistry, J.

    ABSTRACT: There is intense interest in developing methods to regulate proliferation and differentiation of stem cells into neuronal fates for the purposes of regenerative medicine. One way to do this is through in vivo pharmacological engineering using small molecules. However, a key challenge is identification of relevant signaling pathways and therein druggable targets to manipulate stem cell behavior efficiently in vivo. Here, we use the planarian flatworm as a simple chemical-genetic screening model for nervous system regeneration to show that the isoquinoline drug praziquantel (PZQ) acts as a small molecule neurogenic to produce two-headed animals with integrated CNSs following regeneration. Characterization of the entire family of planarian voltage-operated Ca(2+) channel α subunits (Ca(v)α), followed by in vivo RNAi of specific Ca(v) subunits, revealed that PZQ subverted regeneration by activation of a specific voltage-gated Ca(2+) channel isoform (Ca(v)1A). PZQ-evoked Ca(2+) entry via Ca(v)1A served to inhibit neuronally derived Hedgehog signals, as evidenced by data showing that RNAi of Ca(v)1A prevented PZQ-evoked bipolarity, Ca(2+) entry, and decreases in wnt1 and wnt11-5 levels. Surprisingly, the action of PZQ was opposed by Ca(2+) influx through a closely related neuronal Ca(v) isoform (Ca(v)1B), establishing a novel interplay between specific Ca(v)1 channel isoforms, Ca(2+) entry, and neuronal Hedgehog signaling. These data map PZQ efficacy to specific neuronal Ca(v) complexes in vivo and underscore that both activators (Ca(v)1A) and inhibitors (Ca(v)1B) of Ca(2+) influx can act as small molecule neurogenics in vivo on account of the unique coupling of Ca(2+) channels to neuronally derived polarity cues.
