Résumé

Nuclear factor-kappaB (NF-kappaB) has been implicated in anti-apoptotic gene transactivation, according to its transcriptional activity. The present study was designed to investigate whether constitutive NF-kappaB activity could modulate basal apoptosis and intrinsic radiosensitivity of KB head-and-neck carcinoma cell line and KB3 subline. The KB3 subline was more radiosensitive (SF2 = 0.48, alpha = 0.064) than the radioresistant KB parental cell line (SF2 = 0.80, alpha = 0.114).
