Conditional transgenic miR-9 sponge mice exhibit developmental defects in dendrite growth due to up-regulation of the transcriptional repressor REST.

During neurogenesis, Neurogenin 1 activates the microRNA miR-9, which directly targets the Jak-Stat pathway to inhibit astrogliogenesis.

Gene manipulation combined with behavior analysis reveals a role of miR-9 in modulating basal-ganglia-dependent developmental vocal learning and adult vocal performance via regulating the FOXP1/FOXP2 gene network and dopamine signaling in songbirds.

Mir155 showed a catabolic effect on osteogenesis and bone mass phenotype via interaction with the S1pr1 gene, suggesting inhibition of Mir155 as a potential approach to bone regeneration and bone defect healing.

miR-31 drives proliferation of intestinal stem cells, and protects intestinal stem cells against apoptosis both during homeostasis and regeneration in response to ionizing radiation injury, and promotes intestinal tumorigenesis through regulation of multiple signaling pathways.

Coordinate control of lysosomal v-ATPase subunits and biogenesis factor TFEB by miR-1 identifies a key regulatory axis with strong links to age-related proteotoxic disease.

Combination of in vitro and in vivo approaches reveal how learning suppresses the microRNA system to trigger de novo synthesis of plasticity proteins, a missing link in the current model of microRNA-mediated translation in persistent synaptic plasticity and memory.

A genetic oscillator composed of NHR-23 and let-7 family of microRNAs links the molting cycle timer and the heterochronic pathway to regulate the pace of molting in C. elegans and ensure that worms molt only four times.

Primate-specific miR-934 mediates neurogenesis and downstream neuronal differentiation processes, modulating the expression of genes associated with the subplate, a region most prominent in primates, emerging during early cortical development.

The tumor suppressor p53 prevents tumor cell growth by employing a small RNA called miR-139-5p to inhibit the activity of an tumorigenic protein, cAMP-specific phosphodiesterase 4D.
