Fig. 3: Dead tubules provoke Mincle and proinflammatory cytokine expression in macrophage via SAP130.

A Dead cells were stained by Trypan blue and detected by Countess™ II FL Automated Cell Counter. B SAP130 was detected in the supernatant of dead tubule epithelial cells (TECs) induced by heat stress, while expression was barely detected in normal cells. C–D Mincle and MCP-1 expression was induced in a dose and time-dependent manner in macrophages treated with SAP130-enriched supernatant of dead TECs. E–G SAP130 siRNA transfection reversed the proinflammatory effect caused by dead TECs. Data were presented as mean ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001 compared to Ctrl. #p < 0.05, ##p < 0.01 compared to NC. Ctrl Control, NC Scramble negative control.
