Genome-wide analysis of long noncoding RNA turnover.

Genome-wide analysis for determining RNA turnover is an advanced method in RNA biology that examines the specific half-life of nuclear noncoding RNA (ncRNA). In particular, a pulse-labeling method using uridine analogs enables the determination of RNA stability under physiologically undisturbed conditions. The technique involves pulse labeling of endogenous RNAs in mammalian cells with 5'-bromo-uridine (BrU), followed by measuring the chronological decrease of BrU-labeled RNAs using deep sequencing. The method is called BrU immunoprecipitation chase assay (BRIC) or BRIC through deep sequencing (BRIC-seq). Here, we describe a detailed protocol and technical tips for BRIC-seq.
