MicroRNAs (miRNAs) are conserved noncoding RNAs that function as posttranscriptional regulators of gene expression. miR-9 is one of the most abundant miRNAs in the brain. Although the function of miR-9 has been well characterized in neural progenitors. its role in dendritic and synaptic development remains largely unknown. https://pipingrockers.shop/product-category/clear-sinus/
