Webb2 okt. 2024 · Nuclear receptors such as the Pregnane X Receptor (PXR) are known to be key regulators of ABC drug transporters such as Abcb1, Abcc2, Abcc3, and Abcg2 [ 25, 26, 27, 28 ]. It is well known that PXR is activated by endogenous steroidal hormones and their metabolites, the levels of which are dramatically elevated during pregnancy.
