Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?

Mmu-mir-223 is a microRNA that is upregulated in various biological contexts [PMC5617494]. In CD34+SCA1+ BMHSCs, the expression of mmu-mir-223 was found to be upregulated after treatment with CTX [PMC5617494]. Knocking out mmu-mir-223 resulted in the de-repression of exclusive targets with 8mer sites, indicating that the 5'-isomiR of mmu-mir-223 affected these targets [PMC3919606]. The expression levels of mmu-mir-223 were normalized against β-actin [PMC4755013]. In UVB irradiated mice, mmu-mir-223 was found to be upregulated compared to untreated mice [PMC3597329]. Mice with DSS-induced colitis were treated with mmu-mir-223 loaded nanoparticles, which resulted in therapeutic effects [PMC9024817]. Mmu-mir-223 mimic treatment repressed the expression of NLRP3 and increased the repression of IL-1β, IL-6, TNF-α, and CXCL1 and CXCL2 mRNA transcripts [PMC6113393]. G1 arrest and the presence of p27 regulated three miRs including mir233 [PMC4012735]. Several miRNAs including mir233 increased their expression significantly at different times post-infection [PMC9861972].

Do you think this miRNA is real?
Comments
Mouse mir-223 is predicted [2] based on homology to a reported miR from human (MIR:MI0000300) [1]. Its expression was later verified by cloning [3].
