Abstract:
Objective To investigate the expression of phosphoinositide 3-kinase (PI3K) and protein kinase B (Akt) and their role in pathogenesis in laryngeal squamous cell carcinoma. Methods Immunohistochemical S-P method was used to detect the expression of PI3K and p-Akt in 40 paraffin-embedded human laryngeal squamous cell carcinoma, 20 cases of polyp of vocal cords and 20 cases of laryngeal papilloma. All the samples were stained by HE method to confirm their pathologic characteristics. Positive rates of PI3K and p-Akt were evaluated by microscopy. Results PI3K and p-Akt showed low expression in the polyp tissues of vocal cords, while they were of significantly higher expression in laryngeal squamous cell carcinoma (P
