| Description: |
The increasing global burden of chronic kidney disease (CKD) magnifies an urgent need to find treatable targets. Monocyte chemoattractant protein-1 (MCP-1/CCL2) is a chemokine secreted by kidney tubular epithelia in response to a variety of stimuli. To better understand the effects of tubular MCP-1 in response to kidney injury, we generated tubular epithelia-specific MCP-1 knockout mice (KO; Pax8-Mcp-1fl/fl). We then exposed these mice and their control littermates to Adriamycin (Adr; 18 mg/kg, IV bolus). Thirty-two days after Adr injection, Mcp-1 transcript and protein levels were suppressed in the KO mice compared to their wild-type (WT) littermates. The KO mice exhibited no effect on survival, change in body weight, albuminuria, kidney function, glomerular or tubular injury, or tubulointerstitial fibrosis compared to WT. Overall, the results suggest that tubule-secreted MCP-1 is not necessary for progression of Adr-induced injury. These findings contribute to our understanding of the role of MCP-1 in kidney injury. |
