1 After treatment with forskolin for 12 or 24 hours, the number of p-CREB (Ser133) and AQP5 positive cells increased, p-CREB (Ser133) and AQP5 protein increased, and AQP5 mRNA was increased. Colforsin cAMP responsive element binding protein 1 Rattus norvegicus
2 After treatment with forskolin for 12 or 24 hours, the number of p-CREB (Ser133) and AQP5 positive cells increased, p-CREB (Ser133) and AQP5 protein increased, and AQP5 mRNA was increased. Colforsin cAMP responsive element binding protein 1 Rattus norvegicus
3 CONCLUSION: Both H89 (PKA inhibitor) and forskolin (cAMP inducing medicine) regulate AQP5 production through the cAMP-PKA/CREB pathway, which could influence the secretory function of the submucosal glands in nasal epithelium. Colforsin cAMP responsive element binding protein 1 Rattus norvegicus
