Experimental details: Immunohistochemistry analysis of paraffin-embedded Phospho-MLKL (Ser358) in human gastric cancer tissue sections. Antigen retrieval was performed using citrate buffer. Samples were blocked with blocking buffer (1.5 hr, 22°C), incubated with Phospho-MLKL (Ser358) polyclonal antibody (Product # PA5-105678) using a dilution of 1:100 (1.5 hr, 22°C), followed by HRP conjugated goat anti-rabbit.

Experimental details: 6 Figure rSAA3 induces RIP3 expression and MLKL phosphorylation. (a) The protein levels of pro- and cleaved caspase-3, caspase-8 and caspase-9 in AR42J cells under CCK stimulation with or without rSAA3 were measured by western blot. (b) The mRNA levels of RIP1 and RIP3 in AR42J cells under CCK stimulation with or without rSAA3 were measured by quantitative RT-PCR. The results are shown as the relative levels of gene transcripts, with those of the no treatment group set as 1. (c) The protein levels of RIP3 and p-MLKL in AR42J cells under CCK stimulation with or without rSAA3 were measured by western blot. beta-actin and total MLKL were used as loading control. (d , e) The quantification of the blots in c is shown. All quantitative data shown are means +- s.e.m. based on triplicate measurements. # P < 0.05 versus the control group, * P < 0.05, **P < 0.01, *** P < 0.001 versus the CCK group. CCK, cholecystokinin; MLKL, mixed lineage kinase domain-like protein; mRNA, messenger RNA; RIP1, RIP3, receptor-interacting protein 1; RIP3, receptor-interacting protein 3; rSAA3, recombinant serum amyloid A 3; RT-PCR, real-time PCR.

Experimental details: 8 Figure rSAA3 induced acinar cell necroptosis through an RIP3-dependent pathway. (a) Caspase inhibitor (Q-VD-Oph) was added to AR42J cells 1 h prior to CCK treatment with or without rSAA3 stimulation. RIP3 inhibitor was added to AR42J cells 30 min prior to treatment with a caspase inhibitor. Annexin V/PI double staining was used to measure the cell death by flow cytometry. Double-negative staining represents live cells, positive staining for Annexin V/FITC and negative staining for PI represents early apoptotic stage and double-positive staining represents late apoptotic and necrosis stage. Q stands for Q-VD-Oph, G stands for GSK 872. (b) The ratios of Annexin V + /PI + are shown. (c) The protein levels of p-MLKL, MLKL, pro- and cleaved caspase-8 in AR42J cells were measured by western blot after stimulation. beta-actin and total MLKL were used as loading control. (d) The quantification of p-MLKL/MLKL in c was shown. All quantitative data shown are means +- s.e.m. based on triplicate measurements. * P < 0.05, *** P < 0.001. CCK, cholecystokinin; FITC, fluorescein isothiocyanate; MLKL, mixed lineage kinase domain-like protein; PI, propidium iodide; RIP3, receptor-interacting protein 3; rSAA3, recombinant serum amyloid A 3.
