TTNPB (Arotinoid Acid) is a potent RAR agonist, and inhibits binding of [3H]tRA with IC50 of 5.1 nM, 4.5 nM, and 9.3 nM for human RARα, β, and γ, respectively.
| Cell Experiment | |
|---|---|
| Cell lines | T47D cells and 184 cells |
| Preparation method | Human mammary epithelial cells are maintained in Mammary Epithelial Basal Medium (MEBM) supplemented with the Mammary Epithelial Growth Media (MEGM) bullet kit. 184 and 184B5 cells are maintained in MEBM sodium-bicarbonate free (MEBM-SBF) supplemented with the MEGM bullet kit, isoproterenol (10 μM), and transferrin (5 μg/ml). MCF10A cell lines are maintained in DME/F12 containing 5% heat inactivated horse serum, penicillin/streptomycin (100 μg/ml and 100 μg/ml), hydrocortisone (1.4μM), insulin (10 μg/ml), choleratoxin (100 ng/ml), and EGF (20 ng/ml). Breast cancer cell lines are maintained in Improved MEM Zinc Option containing 10% fetal bovine serum, 1% glutamine, and 1% penicillin/streptomycin. For growth assays, cells are treated with the different retinoids for the specified number of days with media and treatment changes every other day in T47D cells and every 2 days in 184 cells. Cell proliferation is measured according to the protocol for the CellTiter 96 Aqueous Non-Radioactive Cell Proliferation Assay. This colorimetric assay determines the number of viable cells in a sample. Each point represents samples done in quadruplicate |
