Disease link between hsa-let-7a and Hodgkin's lymphoma.
miRNA ID (from miR2Disease)hsa-let-7a
MethodNorthern blot, qRT-PCR etc
DescriptionmiR-9 and let-7a functionally targeted specific binding sites in the 3' untranslated region of PRDM1/blimp-1 mRNA and repressed luciferase reporter activities through repression of translation. Similar to their in vitro counterparts, the majority of HRS cells in primary Hodgkin lymphoma (HL) cases showed weak or no PRDM1/Blimp-1 expression. Over-expression of miR-9 or let-7a reduced PRDM1/Blimp-1 levels in U266 cells by 30% to 50%, whereas simultaneous inhibition of their activities in L428 cells resulted in an approximately 2.6-fold induction in PRDM1/Blimp-1. MiRNA-mediated down-regulation of PRDM1/Blimp-1 may contribute to the phenotype maintenance and pathogenesis of HRS cells by interfering with normal B-cell terminal differentiation, thus representing a novel molecular lesion, as well as a potential therapeutic target in HL.
