Summary

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

MIR574 is a microRNA encoded by the gene ID: 693159, located on human chromosome 4p14, and is involved in a multi-step biogenesis process [PMC9855975]. It has been identified as a novel self-ligand of TLR7, capable of activating plasmacytoid dendritic cells (pDCs) in the context of systemic lupus erythematosus (SLE) when contained within exosomes [PMC9762196]. Additionally, MIR574 has been associated with epigenetic changes, with age-demethylated sites identified within its encoding gene [PMC4396570]. It is also implicated in cancer biology; MIR574 was consistently down-regulated across all central nervous system (CNS) tumor samples and was part of a panel that could distinguish CNS tumors from controls with high diagnostic accuracy [PMC8235499]. Furthermore, MIR574 expression has been observed in neurons and altered in certain cancer types such as gastric, thyroid, and brain cancer [PMC8018161], [PMC9775590]. Gains covering the MIR574 gene have been reported in certain patient samples indicating its potential involvement in disease progression or as a diagnostic marker [PMC9775590]. Lastly, it has been suggested that MIR574 could be involved in the regulation by acting as a target for endogenous miRNA sponges such as LNC473 [PMC7419277].
