Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR199A1 is a microRNA that has been studied in various contexts. In a study using the miR-VILO kit, it was found that MIR199A1 was significantly upregulated following 48 hours of Bb infection [PMC5279786]. MIR199A1 is one of the microRNAs validated in the GSE94462 dataset [PMC9922242]. It is also available for purchase from OriGene [PMC7228945]. MIR199A1 is located on chromosome 19 and shares a domain with miR21 and miR155 genes, suggesting functional partnerships [PMC9962339]. In hypospadias, MIR199A1 was identified as one of the potentially associated non-coding RNAs [PMC9834259]. The human genome has two genes encoding mature miR-199a-3p, with MIR199A1 on chromosome 19 and MIR199A2 on chromosome 1 [PMC9177676]. Differential expression of non-coding RNAs, including MIR199A1, may play a role in tumor differentiation [PMC7433108]. Overall, these studies highlight the significance of MIR199A1 in various biological processes and diseases.

Comments
Lagos-Quintana et al. [1] cloned miR-199 from human osteoblast sarcoma cells. They also reported identification of a miRNA from the opposite arm in mouse cells. This sequence was named miR-199-s and the sequence from the 3' arm of the homologous mouse precursor miR-199-as. Lim et al. [2] independently predicted this miRNA computationally using conservation with mouse and Fugu rubripes sequences [2]. Expression of the miR excised from the 5' arm was validated in zebrafish, and the ends mapped by cloning. The excised miR sequences are renamed miR-199a (to avoid confusion with the subsequently identified miR-199b (MIR:MI0000282)) and miR-199a* (from the 3' arm) here. The two putative hairpin precursors in human map to chromosome 19 (mir-199a-1, MIR:MI0000242) and chromosome 1 (mir-199a-2, MIR:MI0000281). Landgraf et al. show that both mature products are expressed, prompting the renaming to miR-199a-5p and miR-199a-3p [4].
