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

MIR652 is a microRNA that has been studied in various contexts. In the EOMG subgroup, MIR652 was found to be in low levels, along with other miRNAs such as miR518d, let7g, miR-192, miR24, miR15b, let7e, miR221, miR-345, miR20b, miR-140 and miR331 [PMC3956820]. In both KO and KI mice models, MIR652 was upregulated and negatively regulated spermatid differentiation [PMC10001410]. In breast cancer cases versus controls, MIR652 was found to be downregulated in serum samples [PMC9967215]. Furthermore, MIR652 was identified as a potential biomarker for breast cancer in multiple independent clinical studies [PMC9967215]. Additionally, the expression of MIR652 has been analyzed in relation to tumor relapse and overall survival in patients with triple-negative breast cancer (TNBC) [PMC7392022]. A four-miRNA signature consisting of MIR18b (miRNA-18b), MIR103 (miRNA-103), MIR107 (miRNA-107), and MIR652 was found to be predictive of tumor relapse and overall survival in TNBC patients [PMC7392022]. Overall, these studies highlight the potential role of MIR652 as a biomarker for various diseases and its involvement in spermatid differentiation.

Annotation confidence High
Do you think this miRNA is real?
Comments
The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [2]. The 3' end of the miRNA is offset with respect to previous annotations. miR-652 cloned in [2] has a 1 nt 3' extension (U), which is incompatible with the genome sequence.
