1 In this study, we have examined the effects of physiologic-like exposure doses to dexamethasone and/or pulsatile (masculine) or constant (feminine) human growth hormone on expression levels of CYP3A4, 1A2, 2D6, and 2E1 and the glucocorticoid and growth hormone receptors in hepatocyte cultures obtained from men and women donors.

2 The masculine-like pulsatile growth hormone profile suppresses dexamethasone-induced CYP3A4, 1A2, and 2D6, whereas the feminine-like constant profile is permissive allowing isoform expression to be equal to or greater than glucocorticoid induction alone.
