Proteomics and phosphoproteomics of sepsis induced acute and chronic kidney disease

Sepsis induced acute kidney injury (AKI) is associated with a rapid decline of kidney function, leading to unacceptably high morbidity and mortality rate as well as progression to chronic kidney disease (CKD). We have recently developed a septic AKI mouse model. By quantitatively assessing the kidney proteome and phosphoproteome changes upon bacterial infection, we accurately quantified over 2,200 kidney proteins with high confidence, which provided us the first global overview of the extensively remodeled kidney proteome and revealed widespread metabolic and oxidation-reduction processes undergone in septic kidney. This data will give us unprecedented insight into how renal cells response to microbe invasion, and will likely serve as a reference dataset of systems biology.
