    Figure 4. Effect of transfection with miR-708-5p mimic on FOXA2 expression and <t>MUC5AC</t> secretion by A549 epithelial cells. A549 cells were seeded on 24-well plates and transfected with miR-708-5p mimics or negative control siRNA (1 nM) in A549 cells in serum free medium. Cells were harvested for RNA isolation and cell-free supernatants were collected after 24 h. (a) Expression of FOXA2 was normalized to the housekeeping genes PPIA and B2M and compared between treatment with oligo control and miR-708-5p mimics. (b) MUC5AC levels were measured in cell-free supernatants by ELISA and compared between treatment with oligo control and miR-708-5p mimics. Four experiments were performed independently. Significant differences were determined by paired Student’s t-test. * p < 0.05 between the indicated values.

    Fig. 2. GPR120 inhibits IL-4- and IL-13-induced production of MUC5AC and cytokines in 16HBE human bronchial epithelial cells. 16HBE monolayers were incu bated with 10 ng/mL each of IL-4 and IL-13 and co-treated with or without 1 µM of GSK137647A for 48 h. To confirm activation of GPR120, cells were pretreated with 100 µM of AH7614, GPR120 antagonist for 1 h before the experiment.

    Fig. 7. Schematic diagram demonstrating mechanisms by which GPR120 stimulation suppresses cytokine-induced airway remodeling in asthmatic models. Acti vation of type-I IL-4R (IL4Rα/γ-chain dimerization) emanates signaling via activation of insulin receptor substrate (IRS)-phosphoinositide 3-kinase (PI3K)-Akt pathway and JAK-STAT6 pathway, while type-II IL-4R (IL-4Rα/IL-13Rα1 dimerization) activates JAK-STAT6 pathway. GPR120 stimulation by GSK137647A at tenuates airway epithelial remodeling hallmarks including increased MUC5AC, tight junction disruption, and upregulated fibrotic markers. GPR120 stimulation attenuates the epithelial disrupting effects of IL-4 and IL-13 signaling via inhibition of STAT6 and Akt.
