Comments:
Since both glucocorticoid receptor and androgen receptor are present in the MDA-MB-453 cells, and both receptors can act through the MMTV promoter, compounds that act through either androgen receptor or glucocorticoid receptor activate the MMTV luciferase reporter. Androgen receptor agonists such as dihydrotestosterone, and glucocorticoid receptor agonists such as dexamethasone, corticosterone, and aldosterone induce luciferase expression. Responsiveness of the cell line was monitored over time and was stable for more than 80 passages. The cell line is an in vitro tool for research in endocrine activity of the human androgen receptor and glucocorticoid receptor. It can be used to screen chemicals for both androgen receptor and glucocorticoid receptor mediated activities.
Propagation:
ATCC complete growth medium: The base medium for this cell line is ATCC-formulated Leibovitz's L-15 Medium, Catalog No. 30-2008. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. Atmosphere: air, 100%
parental cell line:ATCC HTB-131
