Abstract

Removal of damaged mitochondria through mitophagy is critical for maintaining cellular homeostasis and functions. Increasing evidence implicates mitophagy in red blood cell differentiation, neurodegeneration, macrophage-mediated inflammation, ischemia, adipogenesis, drug-induced tissue injury, and cancer. Considerable progress has been made toward understanding the biochemical mechanisms involved in mitophagy regulation. However, few reliable assays to monitor and quantify mitophagy have been developed, particularly in vivo. In this review, we summarize the recent development of three assays, MitoTimer, mt-Keima and mito-QC, for monitoring and quantifying mitophagy in cells and in animal tissues. We also discuss the advantages and limitations of these three assays when using them to monitor and quantify mitophagy. Impact statement: Removal of damaged mitochondria through mitophagy is critical for maintaining cellular homeostasis and functions. However, reliable quantitative assays to monitor mitophagy, particularly in vivo, are just emerging. This review will summarize the current novel quantitative assays to monitor mitophagy in vivo.
