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.

Synaptic Signaling
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.
The presynaptic neuron fires an action potential that...
