Neuronal Activity-Dependent Regulation of MicroRNAs

Neuronal activity-dependent regulation of MicroRNAs.

MicroRNAs are non-coding short (~23 nucleotides) RNAs that mediate post-transcriptional regulation through sequence-specific gene silencing. The role of miRNAs in neuronal development, synapse formation and synaptic plasticity has been highlighted. However, the role of neuronal activity on miRNA regulation has been less focused. Neuronal activity-dependent regulation of miRNA may fine-tune gene...

Bidirectional activity-dependent regulation of neuronal ion channel phosphorylation.

Activity-dependent dephosphorylation of neuronal Kv2.1 channels yields hyperpolarizing shifts in their voltage-dependent activation and homoeostatic suppression of neuronal excitability. We recently identified 16 phosphorylation sites that modulate Kv2.1 function. Here, we show that in mammalian neurons, compared with other regulated sites, such as serine (S)563, phosphorylation at S603 is supe...

Network Stability from Activity-Dependent Regulation of Neuronal Conductances

Activity-dependent plasticity appears to play an important role in the modification of neurons and neural circuits that occurs during development and learning. Plasticity is also essential for the maintenance of stable patterns of activity in the face of variable environmental and internal conditions. Previous theoretical and experimental results suggest that neurons stabilize their activity by...

Activity-Dependent Regulation of Neuronal Ion Channel Expression During Epileptogenesis

micrornas and asthma regulation.

micrornas participate in the regulation of asthma, the goal of this study is to summarize recent researches on the roles of micrornas in the pathogenesis of asthma. a review of the english medical literatures was conducted by searching pubmed for studies concerning asthma and micrornas. the results of the present study indicate that micrornas play important roles in regulating asthma immune res...
