Ex Input:
To examine the effect of glucocorticoid deficiency on the glucocorticoid receptor , we examine the binding of [ 3H ] dexamethasone to lymphocytes in normal subjects and patients with adrenal insufficiency before and after glucocorticoid replacement therapy .

Ex Output:
glucocorticoid receptor

Ex Input:
We have established optimal conditions for the measurement of glucocorticoid receptors ( GR ) in human white cells using a whole - cell binding assay with [ 3H ] dexamethasone as the ligand , and the subsequent determination of the GR content in normal human lymphocytes and in leukemic cells of patients with various forms of acute and chronic leukemia .

Ex Output:
glucocorticoid receptors

Ex Input:
