Background:The three microRNAs from miRNA cluster MC-let-7a-1ϳlet-7d are often down-regulated in human cancers. Results: We functionally characterized the promoter and investigated the transcriptional regulation of MC-let-7a-1ϳlet-7d. Conclusion: MYC oncoprotein could inhibit the transcription of MC-let-7a-1ϳlet-7d via binding to a noncanonical E-box. Significance: Understanding how MC-let-7a-1ϳlet-7d is regulated could shed light on identifying new molecular targets and designing novel treatment for cancers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
