title: Thyroid hormone, all-trans retinoic acid, and 9-cis retinoic acid functioned as negative modulators of the effect of glucocorticoid on induction of alpha 1-acid glycoprotein mRNA in RLN-10 cells.
abstract: The expression of acute-phase protein genes is controlled by many factors, such as IL-1, IL-6, glucocorticoids, thyroid hormone (T3), and retinoic acids. We studied the interaction of T3, glucocorticoids, all-trans retinoic acid (RA), and 9-cis retinoic acid (9cRA) on the expression of the rat alpha 1-acid glycoprotein (AGP) gene in vitro. Dexamethasone (Dex) activated AGP gene expression in a rat liver derived cell line, RLN-10. Although T3, RA, and 9cRA by themselves had no effect on AGP production, they reduced the response to Dex of the AGP gene.
