Topic: post-transcriptional regulation

Modification of mRNA by methylation is involved in post-transcriptional regulation of gene expression by affecting the splicing, transport, stability and translation of mRNA. Methylation of adenosine at N6 (m6A) is the most common and most important cellular modification occurring in the mRNA of eukaryotes. Evidence that m6A mRNA methylation is involved in regulation of stress response and that its dysregulation may contribute to the pathogenesis of neuropsychiatric disorders is accumulating. We have examined the acute and subchronic (up to 18 days once per day intraperitoneally) effect of the

Voltage-gated sodium channels (Navs) play an integral role in brain function and development, enabling the generation and transmission of electrical signals with implications for neuronal excitability, synapse formation, and circuit establishment. Despite the distinct spatiotemporal expression of Navs, the understanding of their regulation in the developing brain is limited. Here we investigated the involvement of microRNAs (miRNAs), short non-coding RNAs, in the post-transcriptional regulation of sodium channel subunit expression. We carried out Argonaute sequencing on mouse hippocampal tissu
