CX3CL1 and acute kidney injury: In this study, we detected expression of FKN and activation of Wnt/β-catenin signaling pathway in podocytes induced by LPS in vitro and in vivo and examined whether the expression of FKN occurring through regulation of Wnt/β-catenin pathway leads to podocyte injury by reducing expression of podocyte-specific proteins and contributes to risk factors that affect the development of AKI.
