The molecular basis for the receptorless (r-) and activation-labile (act1) phenotypes of glucocorticoid-resistant mutants isolated from glucocorticoid-sensitive human leukemic CEM-C7 cells was determined. Clones isolated from a complementary DNA library prepared from r- ICR27TK.3 cells, in which one glucocorticoid receptor (GR) gene has been deleted,(More)
The role of the ligand in glucocorticoid receptor-mediated transactivation and transrepression of gene expression was investigated. Half-maximal transactivation of a mouse mammary tumor virus-chloramphenicol acetyltransferase reporter gene in transfected cells expressing the human glucocorticoid receptor mutant GRL753F, from which the rate of ligand(More)
Glucocorticoid resistance was investigated in human leukemic CCRF-CEM cells. A mutation (L753F), which renders the human glucocorticoid receptor (hGR) gene functionally hemizygous, was identified in all CEM-derived cell lines analyzed. Allele-specific PCR identified the same mutation in lymph node biopsy material from patient CEM cells. Given the(More)
