Figure 3. Suppressing NOX4 inhibits inflammatory response and injury in KCs. (A, B) Results of FCM assay (n = 3). The cell apoptosis level in L/N + GKT group significantly decreased, lower than that in L/N group. *P < 0.05, compared with Con group; #P < 0.05, compared with L/N group. (C) IF staining (n = 3). GKT suppressed NLRP3 inflammasome activation. The expression levels of NLRP3 and ASC evidently decreased, lower than those in L/N group. (D) ROS detection by DCFH-DA probe (n = 3). GKT inhibited ROS expression, and the number of positive cells markedly decreased, lower than that in L/N group.
