rno-mir-30d: Rno-mir-30d is a microRNA that has been found to target differentially expressed mRNAs [PMC5485288]. In a study, fish oil feeding was shown to reduce the expression of rno-miR-29c and increase the expression of rno-miR-328 and rno-mir-30d, which in turn regulated the expression of Per3, Pcsk9, and Socs1 [PMC5485288]. The expression of rno-miR-29c, rno-miR-328, and rno-mir-30d was further examined using qRT-PCR to validate the findings [PMC5485288]. The miR-30 family includes several miRNAs such as rno-mir-30d that are mainly enriched in the oxidation-reduction process [PMC8315965]. Fish oil supplementation has been shown to alter hepatic expressions of miRNAs including rno-mir-30d, which may contribute to its amelioration of non-alcoholic fatty liver disease (NAFLD) in rats [PMC6321427]. Rno-mir-30b and rno-mir-30d have been found to have a large number of targets [PMC2990713]. These microRNA genes are located within a set of CNV regions associated with type 2 diabetes (T2D) susceptibility loci involving protein-coding genes as well as microRNA genes [PMC2990713][PMC4631338]. Rno-mir-30d is one of the most abundant microRNAs with 50 known validated targets [PMC4113183].
