Previously, the steroid hormone progesterone has been demonstrated to stimulate OATP2B1-mediated transport of estrone-3-sulphate (E(1)S), dehydroepiandrosterone sulphate (DHEAS) and pregnenolone sulphate (PS), which may influence the uptake of precursor molecules for steroid hormone synthesis. However, it is unclear whether OATP2B1
