Flag TNF-induced complex-I immunoprecipitation. MC-38 cells (A) or HT-29 cells (B) were stimulated with Flag-TNF (1 µg/mL) for the indicated time points, followed by Flag immunoprecipitation and immunoblot analysis. HT-29 cells were pre-treated with 1 nM LCL161 for 1 h before Flag-TNF stimulation cell lysates of MC-38 cells (C) or HT-29 cells (D) stimulated with or without TNF were immunoprecipitated with antibody against RIPK1 or antibody against SMYD2, followed by immunoblot analysis. HT-29 cells were pre-treated with 1 nM LCL161 for 1 h before TNF stimulation. E Immunoblot of phosphorylated or total RIPK1 in lysates of WT and SMYD2 deficient HT-29 cells stimulated with TS (Upper panel) or TSZ (Lower panel) at different time points. β-Actin served as a loading control. F A schematic diagram depicting SMYD2 mediated cell death pathways in CRC cells.
