Abstract Background Pregnane X receptor PXR agonists inhibit liver fibrosis. However the rodent PXR activator pregnenolone 16a carbonitrile PCN blocks in vitro hepatic stellate cell-to-myofibroblast trans-differentiation and proliferation in cells from mice with a disrupted PXR gene suggesting there is an additional anti-fibrogenic drug target for PCN. The role of the low affinity glucocorticoid binding site LAGS - which may be identical or associated with the progesterone receptor membrane component 1 PGRMC1 - in mediating this anti-fibrogenic effect has been examined since binding of dexamethasone to the LAGS in liver microsomal membranes has previously been shown to be inhibited by PCN. Results Quiescent rat and human .
