Dexamethasone effect on TN and ER + breast cancer cell growth. a Cell proliferation of breast cancer cells upon GR agonist (dexamethasone, dex) and antagonist (mifepristone, mif) treatment. Columns represent the averages of three biological replicates, with error bars indicating standard deviations. Statistical differences were assessed by ANOVA following Dunnett test to compare different groups. *: p ≤ 0.05; **: p ≤ 0.01; ***: p ≤ 0.001. b No morphological or cell proliferation change have been observed in 3D spheroid cultures.
