mmu-mir-23a: Mmu-mir-23a is a microRNA that has been extensively studied in various contexts [PMC4346489]. In a study by [PMC4346489], it was found that mmu-mir-23a was differentially expressed in both plasma and aorta tissue samples, with its expression being downregulated. This finding was consistent with the results obtained from microarray analysis [PMC4346489]. Furthermore, the study identified three pathways enriched with predicted targets of mmu-mir-23a that were differentially expressed in atherosclerotic tissue compared to control tissue [PMC4346489]. Another study [PMC3597329] investigated the expression of mmu-mir-23a in response to UVB irradiation and baicalin treatment. The results showed that mmu-mir-23a was highly expressed in the baicalin plus UVB treated group compared to the UVB group [PMC3597329]. In addition, mmu-mir-23a has been implicated in various biological processes and diseases, such as neuropathic pain [PMC8914318], asthma [PMC3030602], inflammation, and cancer [PMC4062425]. The role of mmu-mir-23a has also been investigated in the interaction between endothelial cells (ECs) and neural stem/progenitor cells (NSPCs) [PMC7758130]. Furthermore, it has been suggested that mmu-mir-23a is regulated by Smad members and may play a role in oligodendrocyte differentiation and myelin formation [PMC7906897]. Overall, these studies highlight the importance of mmu-mir-23a in various biological processes and diseases.
