High-Throughput Measurement Of Mitochondrial Rna Turnover In Human Cultured Cells

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.
