High-Throughput Measurement of Mitochondrial RNA Turnover in Human Cultured Cells

Methods Mol Biol. 2021:2192:133-146. doi: 10.1007/978-1-0716-0834-0_11.

Abstract

RNA turnover is an essential part of the gene expression pathway, and there are several experimental approaches for its determination. High-throughput measurement of global RNA turnover rates can provide valuable information about conditions or proteins that impact gene expression. Here, we present a protocol for mitochondrial RNA turnover analysis which involves metabolic labeling of RNA coupled with quantitative high-throughput fluorescent microscopy. This approach gives an excellent opportunity to discover new factors involved in mitochondrial gene regulation when combined with loss-of-function screening strategy.

Keywords: Bromouridine (BrU); Metabolic labeling; Mitochondrial RNA; RNA turnover.
