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

MIR199B is a microRNA implicated in various biological processes and disease states. Overexpression of MIR199B does not significantly alter HIF-1α mRNA or NFκB mRNA and protein levels [PMC3645752]. The specific PCR primers for MIR199B have been designed to amplify a 66 bp product [PMC3645752]. MIR199B deficiency in a mouse model leads to increased levels of ACR, BUN, Cr, and proteinuria, suggesting that MIR199B has a protective role that is lost when it is absent [PMC8257373]. In the context of SARS-CoV-2 infection, MIR199B is one of the differentially expressed pri-miRNAs that show increased levels in patients' plasma [PMC9677482]. In breast cancer (BC), MIR199B has been reported as up-regulated [PMC3828615], and it has been studied for its potential role in VEGF transcriptional activation and secretion [PMC4737258]. The microRNA also plays a role in cancer biology by inhibiting the transcription factor HES1, which leads to reduced pluripotency in cancer stem cells and decreased growth of medulloblastoma [PMC3645752]. Furthermore, higher expression levels of MIR199B are associated with shorter progression-free survival (PFS) in patients with certain cancers [PMC6183594].

Annotation confidence High
Do you think this miRNA is real?
Comments
This human miRNA was predicted by computational methods using conservation with mouse and Fugu rubripes sequences [1]. Expression of the excised 5' miR has been validated in zebrafish, the ends mapped by cloning [2], and later verified in human [3].
