Glucocorticoid sensitivity is not related to differential use of GR promoters after 8 hours of prednisolone exposure in ALL. The ratio for the 5′ GR promoter transcripts between the prednisolone-exposed and control samples was calculated. The results are depicted as median (horizontal bars) and the 25th and 75th percentiles. Comparisons of the ratios of these 5 transcripts between GC-sensitive and -resistant patient samples were not significant.
