Learn MoreSlowing down mRNA translation in either the cytoplasm or the mitochondria are both conserved longevity mechanisms. Here, we found a non-interventional natural correlation of mitochondrial and cytoplasmic ribosomal proteins when looking at mouse population genetics, suggesting a mito-cytoplasmic translational balance. Additionally, inhibiting mitochondrial translation in C. elegans in turn reduced cytoplasmic translation and repressed growth pathways while upregulating stress responses at both proteome and transcriptome levels. This coordinated repression of cytoplasmic translation is dependent on the atf-5/Atf4 transcription factor and is conserved in mammalian cells upon inhibiting mitochondrial translation pharmacologically with the antibiotic doxycycline. Lastly, extending this to a mammalian setting using doxycycline-treated germ-free mice, we found repressed cytoplasmic translation and ribosomal proteins in liver. These data demonstrate that inhibiting mitochondrial translation initiates a signaling cascade leading to coordinated repression of cytoplasmic translation, unlike previously described unidirectional cyto-to-mito translational communication in yeast, which can be targeted to promote healthy aging.
