We employed molecular modeling to design and then synthesize fluorescent ligands for the human progesterone receptor. Boron dipyrromethene (BODIPY) or tetramethylrhodamine were conjugated to the progesterone receptor antagonist RU486 (Mifepristone) through an extended hydrophilic linker. The fluorescent ligands demonstrated comparable bioactivity to the parent antagonist in live cells and trigg...
The progesterone receptor has been localized in the rabbit uterus by immunocytochemistry at the electron microscopic level, using monoclonal antibodies and the protein A-gold technique. The progesterone receptor in uterine stromal cells was mainly localized in the nucleus; however, a small fraction of antigen was present in the cytoplasm, where it was associated with the rough endoplasmic retic...
Cytological imprint material from 26 mammary carcinomas was stained with monoclonal antibodies to oestrogen and progesterone receptors in an immunoperoxidase procedure. The staining result was compared with that of parallel stainings of frozen tissue sections of the same tumours. The peroxidase reactions in both techniques were semiquantitatively assessed (histoscore). In both sets of stainings...
PURPOSE The purpose of this research was to identify factors predicting response to preoperative chemotherapy. EXPERIMENTAL DESIGN In a large volume laboratory using standard immunohistochemical methods, we reviewed the pretreatment biopsies and histologic specimens at final surgery of 399 patients with large or locally advanced breast cancer (cT2-T4, N0-2, M0) who were treated with preoperat...
The aim of this study was to investigate the role of progesterone in the meiotic resumption of porcine oocytes. Progesterone production and progesterone receptor (PR) immunoreactivity in cumulus cells were not detected in porcine cumulus-oocyte complexes (COC) when observations were made either just after collection from the follicles or after 28 h cultivation without LH and FSH. However, the a...
