Temporal and sex‑dependent gene expression patterns in a renal ischemia–reperfusion injury and recovery pig model


ABSTRACT: Men are more prone to acute kidney injury (AKI) and chronic kidney disease (CKD), progressingto end-stage renal disease (ESRD) than women. Severity and capacity to regenerate after AKI are important determinants of CKD progression, and of patient morbidity and mortality in the hospital setting. To determine sex diferences during injury and recovery we have generated a female and male renal ischemia/reperfusion injury (IRI) pig model, which represents a major cause of AKI. This study was conducted using farm pigs, hybrids between Large White and Landrace. Five females and five males of four months old, free of specifc pathogens, between 30 and 40 kg of weight were included in this study. This age range was chosen due to the sexual maturity of the animal, allowing hormone efects. Using microarray assays, global transcriptomic analyses of kidney biopsies from this IRI pig model was conducted and revealed a sexual dimorphism in the temporal regulation of genes and pathways relevant for kidney injury and repair. Overall, this study constitutes an extensive characterization of the time and sex diferences occurring during renal IRI and recovery at gene expression level.
