NLRP3 and acute kidney injury: Furthermore, the expression levels of homeodomain interacting protein kinase 2 (HIPK-2), activating tranSrciption factor 3 (ATF3), NACHT, LRR and PYD domains-containing protein 3 (NLRP3), and Rho-associated protein kinase 2 (ROCK2 ) were significantly up regulated in CLP induced AKI model, which was markedly suppressed in Wa-2 mice were subjected to CLP (Supplementary Figure 5).
