Deguelin Potentiates Apoptotic Activity of an EGFR Tyrosine Kinase Inhibitor (AG1478) in PIK3CA-Mutated Head and Neck Squamous Cell Carcinoma
Head and neck squamous cell carcinoma (HNSCC) is known to be intrinsically resistant to inhibitors for epidermal growth factor receptor (EGFR). Until now, clinical outcomes for HNSCC using EGFR inhibitors as single agents have yielded disappointing results. Here, we aimed to study whether combinatorial treatment using AG1478 (EGFR tyrosine kinase inhibitor) and deguelin, which is a rotenoid iso...
متن کاملTyrosine kinase domain mutations of EGFR gene in head and neck squamous cell carcinoma
BACKGROUND Epidermal growth factor receptor (EGFR) is a commonly altered gene that is identified in various cancers, including head and neck squamous cell carcinoma (HNSCC). Therefore, EGFR is a promising molecular marker targeted by monoclonal antibodies and small molecule inhibitors targeting the tyrosine kinase (TK) domain. OBJECTIVE The objective of this study was to investigate the spect...
متن کاملPIK3CA mutations in head and neck squamous cell carcinoma.
PURPOSE Recent studies have reported high frequencies of somatic mutations in the phosphoinositide-3-kinase catalytic alpha (PIK3CA) gene in several human solid tumors. Although gene amplifications of PIK3CA have been reported in head and neck squamous cell carcinoma (HNSCC), small mutation of the gene has not been evaluated in HNSCC previously. In this study, we examined the mutation frequency...
متن کاملAnalysis of PIK3CA and Akt/protein kinase B in head and neck squamous cell carcinoma.
PIK3CA, which encodes the catalytic subunit, p110-alpha, of phosphatidylinositol 3-kinase (PI3K), is implicated in the development and progression of numerous neoplasias including head and neck squamous cell carcinoma (HNSCC). In the present study, we investigated the occurrence of PIK3CA hot-spot mutations in exons 9 and 20, the genomic gain and amplification of PIK3CA, the expression of PIK3C...
متن کاملIncidence of Etiologic Factors in Squamous Cell Carcinoma of Head and Neck in Ahvaz
Introduction: Squamous cell carcinoma (SCC) is the most common head and neck malignancy. Smoking, alcohol consumption, viral infections, exposure, oral hygiene, and dietary, genetic, and occupational factors are the most important etiologic factors. The aim of this study was determining the incidence of etiologic factors in head and neck SCC. Materials and Methods: This is a cross-sectiona...
