 We investigated the expression differences of the TEL-AML1 fusion gene in a leukemia glucocorticoid (GC)-sensitive cell line (CEM) and a GC-resistant cell line (Jurkat).     ///    Expression differences in TEL-AML1 fusion gene in leukemia glucocorticoid-sensitive and -resistant cell lines..     ///    "A methyl thiazolyl tetrazolium assay was used to detect cell proliferation inhibition, flow cytometry was used to observe cell apoptosis, reverse transcription-polymerase chain reaction was used to detect the mRNA expression of TEL-AML1 before and after exposure, and western blotting was used to analyze protein levels of TEL-AML1 before and after exposure. "    ///    Changes in TEL-AML1 expression before and after GC exposure were analyzed.     ///    Inhibition of TEL-AML1 may provide a new therapeutic approach to reverse GC resistance.     ///    Sustained high expression of TEL-AML1 participated in and maintained the occurrence of GC resistance.     ///    "In the exposed group, Jurkat cells showed higher TEL-AML1 expression than did CEM cells (P < 0.05). "    ///    "In the unexposed group, TEL-AML1 gene expression in Jurkat cells was not affected by GC exposure (P > 0.05), while the CEM cells presented significant differences before and after exposure (P < 0.05).
