Human proximal tubular epithelial cells (PTEC) of the kidney are known to respond
to and mediate the disease process in a wide range of kidney diseases, yet their
exosomal production and exosome molecular cargo remain a mystery. Here we
investigate, for the first time, the production and molecular content of exosomes
derived from primary human PTEC cultured under normal and diseased conditions
representing a spectrum of in vivo disease severity from early inflammation,
experienced in multiple initial kidney disease states, through to hypoxia,
frequently seen in late stage chronic kidney disease (CKD) due to fibrosis and
vascular compromise. We demonstrate a rapid reproducible methodology for the
purification of PTEC-derived exosomes, identify increased numbers of exosomes
from disease-state cultures and identify differential expression levels of both
known and unique miRNA and protein species from exosomes derived from different
disease-culture conditions. The validity of our approach is supported by the
identification of miRNA, proteins and pathways with known CKD associations,
providing a rationale to further evaluate these novel and known pathways as
targets for therapeutic intervention.
