Figure Lengend Snippet: Fig. 3 Soyasaponins inhibited the recruitments of TLR4 and MyD88 into lipid rafts in liver tissues. The lipid rafts (fraction 3 and 4) were fractionated from liver tissue lysates by using sucrose gradient ultracentrifugation. The protein levels of flotillin-1 (a lipid raft marker), TLR4 and MyD88 were detected by western blotting. The ratio of the amount of TLR4 (or MyD88) in lipid raft to that in total fractions were quantitatively calculated. Results reported are Means ± SD of samples from six mice in each group (n = 6). Data were statistically analyzed by using one-way ANOVA of SPSS software. *: p < 0.05 v.s. control, #: p < 0.05 v.s. LPS alone

Article Snippet: HEK293T cells were transfected with MyD88 flag expression plasmid (Addgene plasmid #13093) or the empty plasmid vector using the LipofectamineTM 3000 reagent (Invitrogen) by following the recommended protocols.

Figure Lengend Snippet: Fig. 4 Effects of soyasaponins on the protein levels of molecules in TLR4/MyD88 signaling pathway in LPS-stimulated RAW264.7 macrophages. RAW264.7 macrophages were pre-treated with graded concentrations (10, 20 or 40 μmol/L) of soyasaponins (A1, A2, or I) for 2 h and then stimulated with LPS (1 μg/mL) for 30 min (a and b), 1 h (c), or 3 h (d and e). The levels of molecules (MD-2, TLR4, TIRAP, MyD88, p-IRAK4, p-IRAK1 and TRAF6) in TLR4/MyD88 signaling pathway were measured by western blotting. Results reported are Means ± SD of three independent experiments. Data were statistically analyzed by using one-way ANOVA of SPSS software. *: p < 0.05 v.s. control, #: p < 0.05 v.s. LPS alone

Figure Lengend Snippet: Fig. 5 Soyasaponins inhibit the protein expression of MyD88 and TRAF6, and activation of NF-κB in MyD88-transfected HEK293T cells. HEK293T cells were transfected with MyD88-flag plasmid for 24 h, and then treated with graded concentration (20 or 40 μmol/L) of soyasaponin (A1, A2 or I) or ST2825 (a MyD88 inhibitor) for 6 h. The protein levels of TLR4 (a), MyD88 (b), TRAF6 (c), p-p65 and p65 (d) were measured by western blotting. Results reported are Means ± SD of three independent experiments. Data were statistically analyzed by using one-way ANOVA of SPSS software. *: p < 0.05 v.s. control, #: p < 0.05 v.s. MyD88-flag plasmid transfected group
