Abstract:
Objective:Analysis of phosphatidyl inositol 3-kinase catalytic subunit of alpha(PIK3CA) expression in nasopharyngeal carcinoma and prognosis.Method:On normal nasopharyngeal mucosa and tissue adjacent to carcinoma and nasopharyngeal carcinoma tissues serine/threonine protein kinase (pAkt) and the expression of PIK3CA status detection,immunohistochemical method,in-depth analysis is made to the relationship between the development of tumor; The expression of tumour stage,prognosis and IK3CA comprehensive analysis of the relationship between.Result:Tissue adjacent to carcinoma,pAkt in nasopharyngeal carcinoma tissue,the expression of PIK3CA increased significantly(P<0.05). There was a significant correlation between the degree of overexpression of PIK3CA and clinical stage(T stage: r=0.437,P<0.01;N stage: r=0.318,P<0.05; clinical stage:r=0.496,P<0.01).Compared with PIK3CA-negative patients,PIK3CA-positive patients had a worse overall survival(P<0.01).Conclusion:PIK3CA is highly expressed in nasopharyngeal carcinoma,which is significantly associated with worse clinical stage and worse overall survival prognosis.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
