    ..In spermatozoa, beta-microseminprotein was found attached to the cell membrane of the head but not in the tail, and gamma-seminoprotein was not found at all. ..

    ..Inhibin A and activin A, but not inhibin B, serum levels are markedly increased in women with preeclampsia. These hormones might serve as an endocrine marker for preeclampsia. ..

    ..Analysis of the predicted secondary structure of the two precursor polypeptides revealed a strong correlation between structural features and sites of protein processing. ..

    ..A portion (40%) can be activated by trypsin, while the rest is stably inactive PSA. LNCaP cells may serve as a source of the "unreactive" PSA present in prostate cancer patients' serum. ..
