Demonstration of a Glucocorticoid Hormone-receptor Complex in the Cytoplasm of a Hormone-Responsive Tumour

Specific substances binding [(3)H]-triamcinolone acetonide have been demonstrated in the cytoplasmic fraction of the R3230AC mammary carcinoma using sucrose gradient centrifugation. These receptors, which exhibit sedimentation coefficients of 8-9 Svedberg units, are relatively specific for glucocort...

Descripción
Sumario:Specific substances binding [(3)H]-triamcinolone acetonide have been demonstrated in the cytoplasmic fraction of the R3230AC mammary carcinoma using sucrose gradient centrifugation. These receptors, which exhibit sedimentation coefficients of 8-9 Svedberg units, are relatively specific for glucocorticoid ligands and possess a high affinity for triamcinolone acetonide (K(d)∼7 × 10(-8) mol/1).
