Figure Lengend Snippet: Figure 1. Curcumin induced NLRP3 priming and caspase-1 activation in mouse malignant mesothelioma cells without proinflammatory cytokine processing. A, MTS assays revealed that curcumin inhibited mouse malignant mesothelioma cell growth in a manner that was dose and time dependent. Mouse malignant mesothelioma cells treated with curcumin (40 mmol/L for 48 hours) resulted in increased mRNA levels of NLRP3 (B) compared with control malignant mesothelioma cells, which was inhibited by actinomycin D pretreatment for 1 hour (C). Pro-IL-1b mRNA levels were not significantly altered by curcumin (D), whereas ASC mRNA levels were significantly decreased (E). Caspase-1 activation (F) and HMGB-1 release (G) significantly increased in mouse malignant mesothelioma cells in response to curcumin (20 and 40 mmol/L for 48 hours). , P 0.05 when compared with control; †, P 0.05 when compared with curcumin-only treatment group.

Figure Lengend Snippet: Figure 3. Curcumin mediates NLRP3 priming and caspase-1 activation without proinflammatory cytokine secretion in human malignant mesothelioma cells. MTS assays revealed that curcumin inhibited HMESO (A), H2461 (B), and H2595 (C) cell growth in a manner that was dose and time dependent. HMESO cells treated with curcumin (40 mmol/L for 48 hours) resulted in increased mRNA levels (D) and protein levels (I) of NLRP3 compared with control malignant mesothelioma cells. Pretreatment with actinomycin D 1 hour before curcumin treatment inhibited curcumin-induced increased mRNA levels of NLRP3 (E). Caspase-1 activation was significantly increased in response to curcumin (40 mmol/L for 48 hours) when measured by caspase-1 activity assay (F) and Western blot analysis of p20 (J) without significant change in secretion of IL-1b (G) and IL-18 (H). Curcumin treatment (40 mmol/L for 48 hours) resulted in increased HMBG1 release in HMESO cells compared with control cells (K). , P value 0.05 when compared with control. †, P < 0.05 when compared with curcumin-only treatment group.

Curcumin treatment (40 mmol/L for 6 hours) resulted in significantly increased ROS in HMESO cells (A) compared with control cells, which was attenuated by NAC pretreatment (40 mmol/L for 18 hours; B). Pretreatment with NAC (40 mmol/L for 18 hours) blocked increased NLRP3 mRNA levels (C), caspase-1 activity (D), cleavage of p20 (E), and HMGB1 release (F) by curcumin (40 mmol/L for 48 hours) in HMESO cells. Expression of NLPR3 protein (G) was not altered with NAC pretreatment.
