Alterations in mitophagy have been increasingly linked to aging and age-related
diseases. There are, however, no convenient methods to analyze mitophagy in vivo.
Here, we describe a transgenic mouse model in which we expressed a
mitochondrial-targeted form of the fluorescent reporter Keima (mt-Keima). Keima
is a coral-derived protein that exhibits both pH-dependent excitation and
resistance to lysosomal proteases. Comparison of a wide range of primary cells
and tissues generated from the mt-Keima mouse revealed significant variations in
basal mitophagy. In addition, we have employed the mt-Keima mice to analyze how
mitophagy is altered by conditions including diet, oxygen availability,
Huntingtin transgene expression, the absence of macroautophagy (ATG5 or ATG7
expression), an increase in mitochondrial mutational load, the presence of
metastatic tumors, and normal aging. The ability to assess mitophagy under a host
of varying environmental and genetic perturbations suggests that the mt-Keima
mouse should be a valuable resource.
