mmu-mir-203: Mmu-mir-203 is a microRNA that has been studied in various contexts. It has been shown to be present in a plasmid sequence called PSilencer 4.1-CMV-Puro [PMC4649077]. Mmu-mir-203 is part of a cluster of miRNAs that includes mmu-miR-10a, mmu-mir-330, mmu-mir-342, mmu-mir-470, and mmu-mir-99b [PMC3937077]. These miRNAs have been identified as potential candidates for the protein Oct4 [PMC3937077]. Mmu-mir-203 has also been found to be involved in the MAPK signaling pathway ceRNA network, where it can regulate circRNA1709 and genes such as AKT3, MAPK9, FGF9, and IGF1R [PMC10048691]. Additionally, mmu-mir-203 has been identified as a potential target for several other miRNAs that are either upregulated or downregulated in different contexts [PMC3030602]. It has also been shown to target Zeb1 and Zeb2 genes involved in epithelial to mesenchymal transition [PMC3319598]. Mmu-mir-203 expression can be detected using specific LNATM miRNA primers [PMC3549733]. It is worth noting that the expression of mmu-miR-203 is downregulated in certain conditions such as HFD-induced obesity [PMC3319598]. Furthermore, it has been observed that the 3p arm of the mmu-miR-203 hairpin has a higher abundance than the 5p arm [PMC3919606]. Overall, these studies highlight the importance of mmu-miR-203 in various biological processes.
