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

MIR92A1 is a microRNA that is part of the miR-17~92 cluster, which is encoded by the MIR17HG host gene and includes several other miRNAs such as MIR17, MIR18A, MIR19A, MIR20A, and MIR19B1 [PMC4005632]. This cluster has been found to be upregulated in Alzheimer's disease (AD), with a specific increase in the expression of MIR92A1 observed in the cortex of AD patients [PMC7564652]. The upregulation of miRNAs including MIR92A1 has been linked to the downregulation of their target genes in disease models [PMC6321611]. The role of these miRNAs in AD is complex and not fully understood; however, it has been suggested that MIR92A1 may be involved in memory processes [PMC7564652]. Additionally, a microduplication encompassing the miR-17~92 cluster genes suggests a potential genetic basis for their altered expression levels [PMC4005632]. The conservation of a p53 binding site within the human MIR92A1 locus indicates potential regulatory mechanisms that may be important for its expression and function [PMC9207587].

Comments
Human miR-92a (previously named miR-92 here) has two predicted hairpin precursor sequences: mir-92a-1 (MIR:MI0000093) on chromosome 13 (named mir-92-13 in [1]) and mir-92a-2 (MIR:MI0000094) on chromosome X (named mir-92-X in [1]). miR-92a has also been cloned from mouse embryonic stem cells [2] and is predicted to be expressed from two closely related precursor hairpins (MIR:MI0000719 and MIR:MI0000580). The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [7].
