ContentsRenin, angiotensin converting enzyme, and angiotensin II receptors are expressed in the bovine utero-placental unit, indicating the presence of a local renin-angiotensin system (RAS). Angiotensin II receptors of type AT1 and AT2 as well as non-AT1/non-AT2 binding sites were identified. The expression of both renin and the angiotensin II receptor types in the bovine utero-placental unit differs from that in humans. This fact is probably related to differences in placental architecture. The RAS in the bovine utero-placental unit might be important for growth processes in the endometrium and for placentation. It might also participate in the regulation of the utero-placental blood flow and secretion of hormones. Disturbances in the utero-placental RAS might cause a reduced utero-placental blood flow, intrauterine growth retardation and intrauterine death. [ABSTRACT FROM AUTHOR]
