Oncogene: p53 + (underexpressed)
Comments: RKO-AS45-1細(xì)胞The RKO-AS45-1 cell line was generated from the colon carcinoma RKO (ATCC CRL-2577) cell line by transfection with the open reading frame portions of human cDNAs for GADD45 cloned into the expression vector pCMV. [51464]
The cells contain a stably integrated cytomegalovirus (CMV) promotor driven expression vector. The cells overexpress Gadd45 RNA and protein.
The GADD45 gene is p53-regulated and the Gadd45 protein interacts with proteins involved in both cell-cycle regulation and DNA repair.
The RKO-AS45-1 cell line has reduced ability to repair U.V.-induced DNA damage. [51464]
The RKO-AS45-1 cell line can be used together with its parental cell line, RKO (ATCC CRL-2577) to investigate the effects of Gadd45 on DNA repair, apoptosis and drug sensitivity.
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: A subcultivation ratio of 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. RKO-AS45-1細(xì)胞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
