Abstract 3550: Inhibition of either LIN28A or ZCCHC11 (TUT4) provides distinct effects on the expression of the let-7 miRNA family and tumor cell proliferation
Abstract:The LIN28A and LIN28B oncogenes are overexpressed in about 15% of human cancers, and they selectively block the expression of the tumor suppressor miRNA let-7 family, comprising twelve members (let-7a-1, -2, -3, let-7b, let-7c, let-7d, let-7e, let-7f-1, -2, let-7g, let-7i and miR-98) expressed from eight distinct loci. Upon binding to pre-let-7, LIN28A recruits ZCCHC11, a 3′ terminal uridylyl transferase, responsible for let-7 poly-uridylation and subsequent targeting of poly-uridylated let-7 miRNA for degrada… Show more
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.
