Abstract
Glomerulonephritis (GN) is a set of pathological conditions that result in the destruction of glomeruli and loss of renal function, commonly leading to the development of end-stage renal disease. Current pharmacotherapy is limited to immunosuppressive therapy. In the present study, we found a novel antinephritic effect of a tricaprylin emulsion in the anti-glomerular basement membrane (anti-GBM) GN rat model. We evaluated the treatment in vivo by comparing administration of the emulsion with administration of a casein kinase II (CK2) inhibitor in this rat model, and performed a gene ontology-based microarray analysis to reveal in silico the detailed mechanism of action. Our results showed that administration of the tricaprylin emulsion, or even tricaprylin alone, significantly ameliorated the anti-GBM antibody-induced renal dysfunction in these rats. We believe that tricaprylin is the key active antinephritic component of the emulsion and might be a promising drug for the effective treatment of nephritis. Moreover, with respect to microarray analysis, we developed a generally applicable and rapid method to compare gene expression profile data for multiple models of nephritis and clinical samples from a public domain microarray database.
