mmu-mir-3470b: Mmu-mir-3470b is a microRNA that has been found to interact with Piwil4, along with mmu-miR-210-5p, while Piwil1 and Piwil2 interact with a larger number of miRNAs [PMC8509654]. Mmu-mir-3470b is one of the miRNAs that may serve as a biomarker for different time points after ischemic stroke, along with other miRNAs such as mmu-miR-2137, mmu-miR-3085-3p, mmu-miR-5126, and mmu-miR-847-5p [PMC6798056]. Following cerebral ischemia-reperfusion, the expression levels of mmu-mir-3470b and other miRNAs were found to change over time [PMC6798056]. Mmu-mir-3470b has been shown to increase hypersensitivity during tonic inflammatory pain states in mice [PMC4579042]. Lentiviral injections of mmu-mir-3470b have been found to downregulate Comt mRNA levels in mice [PMC4579042]. Mmu-mir 3470a and mmu-mir 3470b are located within the B1 transposon sequence and have extensive targets throughout the genome [PMC4579042]. Mmu-mir 3470a and mmu-mir 3470b have been detected after ALPPS surgery and are associated with specific shifts in lipid levels in the hippocampus [PMC6882302] [PMC8295277].
