Cells were lysed in PBS containing 1% nonidet P-40, 0.5% sodium deoxycholate, 0.1% sodium dodecyl sulfate (SDS), 5 μg/mL aprotinin, 100 μg/mL phenylmethylsulfonyl fluoride, 1 μg/mL pepstatin A, and 1 mM ethylenediaminetetraacetic acid (EDTA) at 4 °C for 20 min. Total lysates were quantified using a microBCA kit (Thermo Fisher Scientific, Waltham, MA, USA). Proteins (10 μg) were resolved by SDS-polyacrylamide gel electrophoresis and electrophoretically transferred to a PVDF (poly(vinylidene fluoride)) membrane. The membrane was blocked in 5% fat-free milk in PBST (PBS with 0.05% Tween-20), followed by incubation overnight with the following primary antibodies diluted in PBST: JNK Ab, p-JNK Ab, p38 Ab, p-p38 Ab, ASC Ab, procaspase-1 Ab (diluted to 1:1000, all from Santa Cruz Biotech (Dallas, TX, USA)), p65 Ab (Genetex, Taiwan) and NLRP3 Ab (Adipogen, San Diego, CA, USA). The primary antibodies were removed, and the membrane was washed extensively in PBST. Subsequent incubation with horseradish peroxidase-conjugated goat anti-rabbit antibodies (1:20,000, Santa Cruz Biotech) was performed at room temperature for 2 h. The membrane was washed extensively in PBST to remove any excess secondary antibodies, and the blot was visualized with enhanced chemiluminescence reagent (GE Healthcare, South Jakarta, Indonesia).

Cells were lysed in PBS containing 1% nonidet P-40, 0.5% sodium deoxycholate, 0.1% sodium dodecyl sulfate (SDS), 5 μg/mL aprotinin, 100 μg/mL phenylmethylsulfonyl fluoride, 1 μg/mL pepstatin A, and 1 mM ethylenediaminetetraacetic acid (EDTA) at 4°C for 20 minutes. Total lysates were quantified using a microBCA kit (Thermo Fisher Scientific, Waltham, MA). Proteins (10 μg) were resolved by SDS-polyacrylamide gel electrophoresis and electrophoretically transferred to a PVDF membrane. The membrane was blocked in 5% fat-free milk in PBST buffer (PBS with 0.05% Tween-20) followed by incubation overnight with the following primary antibodies diluted in PBST buffer: TM antibody (Ab), MMP-2 Ab, JNK Ab, pJNK Ab, p38 Ab, pp38 Ab, c-jun Ab, c-fos Ab, lamin B1 Ab (diluted used in 1 : 1,000, all from Santa Cruz Biotech [Dallas, TX]), MMP-9 Ab (Abcam, Cambridge, UK), p65 Ab, and p53 Ab (Genetex, Irvine, CA). The primary antibodies were removed, and the membrane was washed extensively in PBST buffer. Subsequent incubation with horseradish peroxidase-conjugated goat anti-rabbit antibodies (1 : 20,000, Santa Cruz Biotech) was performed at room temperature for 2 hours.
