Abstract
We screened cell line and plasma-derived exosomes for molecules that localize to mitochondria or that reflect mitochondrial integrity. SH-SY5Y cell-derived exosomes contained humanin, citrate synthase, and fibroblast growth factor 21 protein, and plasma-derived exosomes contained humanin, voltage-dependent anion-selective channel 1, and transcription factor A protein. Nuclear mitochondrial (NUMT) DNA complicated analyses of mitochondrial DNA (mtDNA), which otherwise suggested exosomes contain at most very low amounts of extended mtDNA sequences but likely contain degraded pieces of mtDNA. Cell and plasma-derived exosomes contained several mtDNA-derived mRNA sequences, including those for ND2, CO2, and humanin. These results can guide exosome-focused, mitochondria-pertinent biomarker development.Entities:
