Figure 4. Suppressing NOX4 inhibits inflammatory factor expression and NLRP3 activation. (A) Results of cell viability assay (n = 3). GKT improved the cell viability, which was higher than that in L/N group. ^*P < 0.05, compared with Con group; ^#P < 0.05, compared with L/N group. (B–D) Expression of inflammatory factors (n = 3). GKT reduced the expression of inflammatory factors. The levels of IL-6, TNF-α and IL-1β in L/N + GKT group markedly decreased, lower than those in L/N group. ^*P < 0.05, compared with Con group; ^#P < 0.05, compared with L/N group. (E, F) Detection of protein expression (n = 3). After GKT suppressed NOX4, the activation of NLRP3 inflammasome was suppressed, and the expression of NLRP3, ASC and Caspase-1 decreased, significantly lower than that in L/N group. ^*P < 0.05, compared with Con group; ^#P < 0.05, compared with L/N group.
