概要：The cells contain a stably integrated human papilloma virus(HPV) E6 oncogene under control of the cytomegalovirus(CMV) promoter.
The HPV E6 oncogene causes a decrease in normal p53 levels and functions.The RKO-E6 cell line lacks appreciable functional p53.Disruption of normal p53 function in human colon carcinoma RKO cells with the human papillomavirus E6 oncoprotein results in reduced repair of u.v.-induced DNA damage and also loss of induced repair following cellular u.v.-irradiation.RKO cells contain wild-type p53 but lack endogenous human thyroid receptor nuclear receptor(h-TRbeta1).
The level of p53 protein is higher in RKO cells than in RKO-E6 cells.The RKO-E6 cell line can be used together with its parental cell line, RKO to investigate the effects of p53 loss on cellular parameters such as p53 mediated transcription and apoptosis.
