Abstract

Suppressor of cytokine signaling 3 (SOCS-3) is an important intracellular negative regulator of several signaling pathways. We found that SOCS-3 is highly expressed in renal proximal tubules during acute kidney injury. To test the impact of this, conditional proximal tubular knockout mice (SOCS-3(sglt2Δ/sglt2Δ)) were created. These mice had better kidney function than their wild-type counterparts in aristolochic acid nephropathy and after ischemia/reperfusion injury. Kidneys of these knockout mice showed significantly more proximal tubular cell proliferation during the repair phase. A direct effect of SOCS-3 on tubular cell cycling was demonstrated by in vitro experiments showing a JAK/STAT pathway-dependent antimitotic effect of SOCS-3. Furthermore, acute damaged kidneys of the knockout mice contained increased numbers of F4/80(+) cells. Phenotypic analysis of these F4/80(+) cells indicated a polarization from classically activated to alternatively activated macrophages. In vitro, SOCS-3-overexpressing renal epithelial cells directly induced classical activation in cocultured macrophages, supporting the observed in vivo phenomenon. Thus, upregulation of SOCS-3 in stressed proximal tubules plays an important role during acute kidney injury by inhibition of reparative proliferation and by modulation of the macrophage phenotype. Antagonizing SOCS-3 could have therapeutic potential for acute kidney injury.

Kidneys of these knockout mice showed significantly more proximal tubular cell proliferation during the repair phase. A direct effect of SOCS-3 on tubular cell cycling was demonstrated by in vitro experiments showing a JAK/STAT pathway-dependent antimitotic effect of SOCS-3.

Phenotypic analysis of these F4/80(+) cells indicated a polarization from classically activated to alternatively activated macrophages. In vitro, SOCS-3-overexpressing renal epithelial cells directly induced classical activation in cocultured macrophages, supporting the observed in vivo phenomenon.

<Abstract>
<AbstractText>Suppressor of cytokine signaling 3 (SOCS-3) is an important intracellular negative regulator of several signaling pathways. We found that SOCS-3 is highly expressed in renal proximal tubules during acute kidney injury. To test the impact of this, conditional proximal tubular knockout mice (SOCS-3(sglt2Δ/sglt2Δ)) were created. These mice had better kidney function than their wild-type counterparts in aristolochic acid nephropathy and after ischemia/reperfusion injury. Kidneys of these knockout mice showed significantly more proximal tubular cell proliferation during the repair phase. A direct effect of SOCS-3 on tubular cell cycling was demonstrated by in vitro experiments showing a JAK/STAT pathway-dependent antimitotic effect of SOCS-3. Furthermore, acute damaged kidneys of the knockout mice contained increased numbers of F4/80(+) cells. Phenotypic analysis of these F4/80(+) cells indicated a polarization from classically activated to alternatively activated macrophages. In vitro, SOCS-3-overexpressing renal epithelial cells directly induced classical activation in cocultured macrophages, supporting the observed in vivo phenomenon. Thus, upregulation of SOCS-3 in stressed proximal tubules plays an important role during acute kidney injury by inhibition of reparative proliferation and by modulation of the macrophage phenotype. Antagonizing SOCS-3 could have therapeutic potential for acute kidney injury.</AbstractText>
