Dexamethasone 16-29 KRAS proto-oncogene, GTPase Rattus norvegicus 122-125 9442036-4 1998 Dexamethasone stimulated p21 promoter activity in a p53-independent manner that required functional glucocorticoid receptors. Dexamethasone 0-13 KRAS proto-oncogene, GTPase Rattus norvegicus 25-28 9442036-6 1998 Analysis of 5" deletions of the p21 promoter uncovered a glucocorticoid responsive region between nucleotides -1481 and -1184, which does not contain a canonical glucocorticoid response element but which can confer dexamethasone responsiveness to a heterologous promoter. Dexamethasone 215-228 KRAS proto-oncogene, GTPase Rattus norvegicus 32-35 9442036-8 1998 Finally, ectopic expression of p21 had no effect on hepatoma cell growth in the absence of glucocorticoids but facilitated the ability of dexamethasone to inhibit cell proliferation. Dexamethasone 138-151 KRAS proto-oncogene, GTPase Rattus norvegicus 31-34
