Abstract

Abstract

Objective To study the molecular mechanism of the infection process of Pseudomonas aeruginosa in human middle ear epithelial cells (HMEECs) . Methods Real-time PCR and Western blotting method were used to detect the m RNA and protein levels of TGF-β1 and Smad2, and the phosphorylation of Smad7 in the infection process of Pseudomonas aeruginosaonhuman middle ear epithelial cells. Results Infection of Pseudomonas aeruginosa in human middle ear epithelial cells significantly increased the m RNA and protein levels of TGF-β1 and Smad2, and also inhibited the phosphorylation of Smad7. Mutation of Opr F and PKC inhibitor Bisindolylmaleimide I could derease the m RNA and protein levels of TGF-β1 and Smad2 and the enhanced the phosphorylation of Smad7 compared with Pseudomonasaeruginosa infected HMEECs. Conclusion Infection of Pseudomonas aeruginosaonhuman activates the TGF-β1 Smad signaling pathway in middle ear epithelial cells.
