Abstract
miRNA biogenesis is a multistep process starting with the cleavage of the primary miRNA transcript in the nucleus by the microprocessor complex. The pri-miRNA processing kinetics has a high impact on the final regulative role of the mature miRNAs on the expression of their target transcripts. Thus studying the in vivo kinetics of the miRNA biogenesis could give more insights into the contribution of each individual miRNA on regulation of gene expression. Here, we describe step by step a method to determine the processing kinetics of pri-miRNAs in vivo, using a pulse-chase approach that can be used in downstream applications such as qPCR or deep sequencing. We explain in detail the various aspects of this approach that can be applied to different mammalian cell types. The nature of this protocol allows the in vivo study of pri-miRNA processing kinetics in cells treated with different conditions, mutants, and/or cancer cell lines under physiological conditions.
