mmu-mir-34b: Mmu-mir-34b is a microRNA that has been studied in various contexts. Primers for mmu-mir-34b were used in a study that investigated its expression in mouse testes [PMC6586303]. Additionally, mmu-mir-34b was confirmed to be differentially expressed in mouse testes using conventional Northern blot analysis [PMC2923610]. Mouse miR-34b (mmu-mir-34b) was used to detect the mouse-specific expression of this microRNA [PMC6761099]. In an A-Myb mutant study, mmu-mir-34b was identified as one of the miRNAs whose expression is significantly reduced [PMC8514520]. The pre-miRNA sequence of mmu-mir-34b was obtained from miRBase [PMC2577349]. For the analysis of mature miRNA expression, cDNA was generated and qPCR was performed using specific primers for mmu-miR-34a, mmu-mir-34b, and mmu-miR-34c [PMC7881031]. In summary, mmu-mir-34b is a microRNA that has been investigated in various studies. It has been shown to be differentially expressed in mouse testes and its specific expression in mice has been detected. Additionally, its reduced expression has been observed in an A-MYB mutant. The pre-miRNA sequence of mmu-mir-34b has been obtained from miRBase. In qPCR analysis for mature miRNA expression, specific primers for mmu-miR-34a, mmu-mir-34b, and mmu-MiR 3c were used.
