ST3GAL3 Promotes the Inflammatory Response of Fibroblast-Like Synoviocytes in Rheumatoid Arthritis by Activating the TLR9/MyD88 Pathway

Figure 5

ST3GAL3 regulated the TLR9/MyD88 signalling pathway. (a) GSEA software was used to analyse the enrichment signalling pathways associated with ST3GAL3 in RA. TLR signalling pathway was finally screened out. (b) Western blotting results showed that ST3GAL3 overexpression promoted the expression of TLR9 and MyD88. (c) Western blotting results showed that si-ST3GAL3 inhibited the expression of TLR9 and MyD88. (d) Western blotting result showed that si-ST3GAL3 inhibited sLeX levels in MH7A cells. (e) Western blotting result showed the activated TLR9/MyD88 signalling pathway by adding with sLeX in MH7A cells. (f) ELISA results showed that ST3GAL3 overexpression increased IL-1β and TNF-α levels. . compared with the indicated group.
