Comments: The RKO-E6 cell line was generated from the colon carcinoma RKO (ATCC CRL-2577) cell line by transfection with pCMV-E6 using Lipofectin. RKO-E6細胞[53390]
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. [51463]
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 (ATCC CRL-2577) cells than in RKO-E6 (ATCC CRL-2578) cells. [53331]
The RKO-E6 cell line can be used together with its parental cell line, RKO (ATCC CRL-2577) to investigate the effects of p53 loss on cellular parameters such as p53 mediated transcription and apoptosis.
Propagation: ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Temperature: 37.0°C
Subculturing: Subcultivation Ratio: RKO-E6細胞A subcultivation ratio of 1:4 to 1:10 is recommended
Medium Renewal: Every 2 to 3 days
Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Preservation: culture medium 95%; DMSO, 5%
Related Products: Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
recommended serum:ATCC 30-2020
parental cell line:ATCC CRL-2577
