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...

Our objectives were to investigate the possible role of VEGFA in bovine placenta steroid synthesis and to determine whether cloned derived placental cells present similar responses as non-cloned ones. Placental cells from cloned (term) and non-cloned (days 90, 150, 210...

The pregnancy-associated hormones, progesterone (P4), pregnanediol-3-glucuronide (PdG), relaxin (RLN) and oestrone sulphate (E1S) in plasma, saliva, milk and urine of alpacas were measured in order to assess their potential use for pregnancy diagnosis. Samples were obtained from 36 female alpacas...
