Evidence for thyroid hormone-dependent and independent glucocorticoid actions in cultured cells. Studies on the induction of growth hormone and glutamine synthetase in GH1 cells and tyrosine aminotransferase in Reuber H-35 cells.
The induction of growth hormone synthesis and mRNA by thyroid hormone in cultured GH1 cells is mediated by the thyroid hormone nuclear receptor. In addition, the regulation of the growth hormone response by glucocorticoid is highly dependent on the action of thyroid hormone. To clarify whether thyroid hormone has a general influence on glucocorticoid action… (More)
