    Abstract:
    Immunoreactive (IR) corticotropin-releasing factor (CRF)-like activity was detectable in the majority of plasma samples obtained from women in the third trimester of pregnancy (68.7 +/- 23.6 pg/ml (14.4 +/- 4.9 fmol/ml); mean +/- SE, n = 15), but not in plasma (less than 10 pg/ml) from first (n = 9) or second (n = 11) trimester of pregnancy, 1 day post partum (n = 7), non-pregnant women (n = 10), or in plasma obtained from patients with Cushing's disease (n = 2) or Nelson's syndrome (n = 1), or in basal (n = 6) or ether-stressed (n = 6) rat plasma. Gel filtration of third trimester pooled plasma revealed that the majority of such material eluted with Kav of rat CRF (1-41). The IR CRF (1-41)-sized material eluted with the identical retention time as rat CRF in a reverse phase high performance liquid chromatography (HPLC) system. The detection of IR CRF exclusively in third trimester maternal plasma, together with our previous demonstration that material physicochemically indistinguishable from it is present in human term placental extracts, suggests that the placenta may be the source of plasma IR CRF.
