双硫仑通过阻断RIPK1/RIPK3/MLKL通路抑制肾足细胞和巨噬细胞发生坏死性凋亡
Disulfiram inhibits necroptosis in podocytes and macrophages by suppressing RIPK1/RIPK3/MLKL pathway
摘要
Abstract
Objective:To explore effect and potential mechanism of disulfiram on necrotizing apoptosis of renal podocytes and macrophages.Methods:Mouse renal podocyte MPC-5 and macrophages J774A.1 and BMDM cells were cultured in vitro and treated with TNF-α,Smac mimetic LCL-161 and pan-caspase inhibitor IDN-6556(TSI)to induce necroptosis.Cell necrosis was detected by propi-dium iodide staining.Western blot was used to detect protein levels of necroptosis markers MLKL,RIPK3 and RIPK1.Immuno-fluorescence microscopy was used to observe the subcellular distribution of RIPK3 and p-MLKL in MPC-5 cells.Results:TSI treat-ment induced significant necroptosis in both MPC-5 cells and macrophages.Disulfiram was able to inhibit necroptosis in these cells in a dose-dependent manner.Moreover,disulfiram markedly blocked the phosphorylation of RIPK1,RIPK3 and MLKL.The aggregation of RIPK3 and p-MLKL were also suppressed by disulfiram.Conclusion:Disulfiram inhibits necroptosis in podocytes and macrophages by suppressing RIPK1/RIPK3/MLKL signaling pathway.关键词
