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

MIR29B1 is a microRNA gene that encodes for the miR-29b-3p sequence, a member of the miR-29 family, which is implicated in various cellular processes and diseases [PMC9601486]. In the context of Alzheimer's disease (AD), MIR29B1 has been found to be downregulated in the cortex of AD patients, suggesting a potential role in the disease's pathogenesis [PMC7564652]. This downregulation may influence AD by targeting genes directly involved in its pathogenesis, such as BACE1, which is involved in amyloid precursor protein processing [PMC7564652]. Additionally, MIR29B1's downregulation could indirectly affect neuron survival and thus contribute to AD progression [PMC7564652]. In other studies, MIR29B1 has been associated with various biological processes; for instance, it has been implicated in increasing milk yield in dairy cattle when co-expressed with MIR148A [PMC6898964], and its upregulation was observed upon knockdown of LASP-1 correlating with reduced MMP9 transcript levels in MDA-MB-231S cells [PMC4651668]. Furthermore, mutations in MIR29B1 have been linked to altered physiological responses such as reduced urine volume and increased renal fibrosis under certain dietary conditions in rats [PMC6156712], highlighting its significance beyond neurodegenerative diseases.

Comments
Mourelatos et al. identified two copies of this sequence mapping to chromosome 7, and assigned the names mir-102-7.1 and mir-102-7.2 [1]. Subsequent genome assemblies suggest the presence of only one miR-102 locus on chromosome 7. Human miR-102 is a homologue of mouse miR-29b (MIR:MI0000143) and so has been renamed here for consistency.
