Half-maximal effective concentration (EC50) was measured using PrestoBlue cell viability assay. Initial EC50 values were measured before dexamethasone treatment started. b B-ALL cells were lysed and lysates were processed for Western blotting analysis using anti-glucocorticoid receptor (GR) and anti-¦Â-actin antibodies. Blots were derived from the same experiment and were processed in paralle %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6449402/
