Summary
Caution, this is an AI generated summary based on literature. This may have errors. ?
MIR129-1, a microRNA involved in gene expression regulation, is transcribed from a genomic locus that includes several underexpressed miRNAs in SMZL [PMC8064455], [PMC8138178]. There is no direct evidence suggesting that MIR129-1 is affected by miRNA eQTL mechanisms due to the proximity of a Parkinson’s disease risk SNP to MIR132, as the original context refers to MIR132 and not MIR129-1 [PMC9645562]. MIR129-1 is implicated in various biological processes including cell proliferation and migration, and its dysregulation has been observed post-spinal cord injury [PMC6394761], [PMC6515063]. Additionally, miR-129-5p, produced by MIR129-1, has been recognized for its role in liver function improvement and anti-inflammatory effects in liver disease models [PMC8138178]. While there is no CpG island near the MIR129-1 promoter, unlike MIR129-2, both are important for transcriptional regulation and are located on different chromosomes [PMC3576298]. Experimental studies on hypoxia have utilized transfection of MIR129-1 mimic to assess its expression under such conditions using qPCR with specific TaqMan probes for validation [PMC7399878].

Comments
This miRNA sequence was predicted based on homology to a verified miRNA cloned from mouse cerebellum [1]. Expression of this miRNA was subsequently verified in a human osteoblast sarcoma cell line [2]. Reference [2] named the human/mouse conserved sequence miR-129b, but subsequent genome searches suggest that the same mature sequence may be expressed from two predicted hairpin precursors in both human (this entry and MIR:MI0000473) and mouse (MIR:MI0000222 and MIR:MI0000585). Landgraf et al. show that the 5' product of mir-129-1 (this entry) is the predominant one, whereas both 5' and 3' products are significantly expressed from mir-129-2 (MIR:MI0000585) [3].
