MicroRNA profiling of wild type and p72 knock-out mice embryos

ABSTRACT: To examine the effect of DEAD-box RNA helicase subunits on the primary miRNAs processing by Drosha complex, we made knockout mice of p72, DEAD-box RNA helicase, a component of Drosha complex. And we compare the miRNA expression profiles derived from whole mice embryo between wild-type and p72 KO mice.

MicroRNAs (miRNAs) control cell proliferation, differentiation and fate through modulation of gene expression by partially base-pairing with target mRNA sequences. Drosha is an RNase III enzyme that is the catalytic subunit of a large complex that cleaves pri-miRNAs with distinct structures into pre-miRNAs. Here, we show that both the p68 and p72 DEAD-box RNA helicase subunits in the mouse Drosha complex are indispensable for survival in mice, and both are required for primary miRNA and rRNA pro  ...[more]
