title: Expression of hypoxia inducible factor-1alpha and its relationship to apoptosis and proliferation in human laryngeal squamous cell carcinoma.
abstract: To investigate the expression of hypoxia inducible factor-1 alpha (HIF-1alpha) and its relationship to apoptosis and proliferation in laryngeal squamous cell carcinoma (LSCC), immunohistochemical method was used to detect the expression of HIF-1alpha and PCNA. Tunnel technique was used to detect in situ cell apoptosis in LSCC. Our results showed that the expression of HIF-1alpha was related to the clinical stages of cancer and lymph node metastasis (P<0.05). The relationship between HIF-1alpha and PCNA was statistically significant (P<0.05) and no relationship was found between HIF-1alpha and apoptosis (P>0.05) It is concluded that HIF-1alpha plays a role in the carcinogenesis of laryngeal carcinoma and is correlated with proliferation, but bears no relationship with the apoptosis of tumor cells in LSCC.
