The PI3K-AKT signaling pathway plays an important role in cell proliferation, apoptosis, cell cycle, and metabolism, and its abnormal activation has been found to be related to the occurrence and development of various tumors. This article aims to explore the expression and clinical significance of the PI3K-AKT pathway in nasal polyps.Firstly, the structure and function of the PI3K-AKT signaling pathway were introduced, and then the expression of related genes in nasal polyps was analyzed. The results showed that the PI3K-AKT signaling pathway was abnormally expressed in nasal polyps, and was related to the size, number, and clinical symptoms of nasal polyps. Among them, the expression of PIK3CA and AKT1 was significantly increased, while the expression of PTEN was significantly decreased.精品文档---下载后可任意编辑In addition, the clinical data of nasal polyps patients were statistically analyzed, and it was found that the abnormal activation of the PI3K-AKT pathway was related to the risk of recurrence and prolonged course of nasal polyps. Therefore, the PI3K-AKT pathway may serve as a new therapeutic target for nasal polyps, providing new ideas and methods for its clinical diagnosis and treatment.【Keywords】PI3K-AKT pathway; gene expression; nasal polyps; clinical significance
