The ROS/GRK2/HIF-1α/NLRP3 Pathway Mediates Pyroptosis of Fibroblast-Like Synoviocytes and the Regulation of Monomer Derivatives of Paeoniflorin

Figure 3

The levels of hypoxia-inducible factor (HIF)-1α and N-terminal domain of human gasdermin D (GSDMD-N) increase in fibroblast-like synoviocytes (FLS) of RA patients and adjuvant-induced arthritis (AA) rats. (a, b) Immunoblot analysis and quantification of HIF-1α and GSDMD-N in the FLS of RA patients. (c, d) Immunoblot analysis of HIF-1α and GSDMD-N expression levels in FLS of normal, AA, AA+MDP, and AA+MTX rats. Data are presented as . . , compared with the control group and ### compared with the AA group (MTX: methotrexate; MDP: monomeric derivatives of paeoniflorin).
