The protein expression is demonstrated in Figures 6B,C, and the expression levels of the protein in the MC group were significantly higher than those in the BC [group difference: TLR4 (0.6067, 95% CI: 0.3450 to 0.8684, p < 0.001), MyD88 (0.5400, 95% CI: 0.2353 to 0.8447, p < 0.001), and NF-κB (0.5967, 95% CI: 0.4805 to 0.7128, p < 0.001)]. Here, MYD88 is linked to breast cancer.
