MIR378B: MIR378B is a microRNA that has been implicated in various cellular processes. It has been shown that circ_0078710 enhances the expression of PRIM2 by sponging MIR378B, and the downregulation of circ_0078710 leads to an increase in MIR378B population, resulting in the downregulation of PRIM2, which is involved in cell proliferation [PMC9774417]. MIR378B has also been found to target Usp22, which is involved in the maintenance of neural stem/progenitor cells [PMC7041117]. In a study that functionally annotated miRNAs, MIR378B was identified as one of the miRNAs involved [PMC6349826]. Another study found that ANIT downregulated MIR378B in rat liver [PMC6349826]. Additionally, MIR378B was found to be upregulated in KSHV (+) tumors and was associated with miR143-3p [PMC8242244]. In a comparison between striatum and cortex tissues, MIR378B was one of the microRNAs that showed significant association with Q values [PMC5764268]. Furthermore, it was observed that MIR378B expression was elevated in CpG-stimulated DCs with miR-378b inhibition but showed no change with miR-378 overexpression [PMC6963666]. In summary, MIR378B is a microRNA that plays a role in cell proliferation and neural stem/progenitor cell maintenance. It has been implicated in various cellular processes and its expression can be regulated by different factors.
