BACKGROUND To evaluate the role of γ-H2AX in peripheral blood lymphocytes (PBLs) as a predictive biomarker of the severity of oral mucositis (OM) in head and neck cancer (HNC) patients with receiving radiotherapy. METHODS In vitro assays for evaluating DNA damage and repair kinetics were performed on blood samples withdrawn from 25 HNC patients undergoing(More)
OBJECTIVE To investigate the relationship between -308 genotype polymorphism in the promoter region of the tumor necrosis factor alpha (TNFalpha) gene and asthenospermia in infertile men. METHODS Allele-specific polymerase chain reaction (ASPCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were used to analyze the(More)
Over-expression of epidermal growth factor receptor (EGFR) or insulin-like growth factor-1 receptor (IGF-1R) have been shown to closely correlate with radioresistance of breast cancer cells. This study aimed to investigate the impact of co-inhibition of EGFR and IGF-1R on the radiosensitivity of two breast cancer cells with different profiles of EGFR and(More)
PURPOSE Mutations in the epidermal growth factor receptor (EGFR)/phosphoinositide 3-kinase (PI3K)/Akt signaling transduction pathway are common in cancer. This pathway is imperative to the radiosensitivity of cancer cells. We aimed to investigate the radiosensitizing effects of the simultaneous inhibition of EGFR and PI3K in breast cancer cells.
