a The effect of TRIF siRNA transfection, as confirmed by Western blot analysis. b Western blotting and c relative protein density of necroptotic proteins after LPS challenge in the scramble and the TRIF silenced HCT-116 cells. d The effect of TNFR1 siRNA transfection, as confirmed by Western blot analysis. e Western blotting and f relative protein density of necroptotic proteins after LPS challenge in the scramble and the TNFR1-silenced HCT-116 cells. g Simultaneous TRIF and TNFR1 siRNA transfections resulted in near-complete depletion of both TRIF and TNFR1 expressions, as confirmed by Western blot analysis. h Western blotting and i relative protein density of necroptotic proteins after LPS challenge in the scramble and the TRIF/TNFR1-silenced HCT-116 cells. pRIPK1 phosphorylated RIPK1, pRIPK3 phosphorylated RIPK3, pMLKL phosphorylated MLKL. #p > 0.05, *p < 0.05, **p < 0.01, and ***p < 0.001. n = 4 in each group.
