The effects of the antiprogestin RU 486 on the human endometrium were investigated. Seventeen postmenopausal women were injected with estradiol (E2) benzoate (0.625 mg/day) for 15 days. Progesterone (P) (25 mg/day) and/or RU 486 (100 or 200 mg/day) were given to groups of 2-3 women during the last 6 days of E2 benzoate treatment. Serial blood samples were(More)
Progesterone receptor (PR) from a human endometrial carcinoma (EnCa 101) grown in nude mice consists of two hormone-binding proteins with mol wt around 116,000 and 85,000. To generate monoclonal antibodies against this receptor, PR was partially purified from EnCa 101 and used to immunize Robertsonian mice. Immune mouse spleens were fused with HL-1 Friendly(More)
Granulocyte macrophage colony-stimulating factor (GM-CSF) has emerged as an important growth factor for trophoblast and other placental cells, leading to improved placental functioning and fetal survival. Recent observations have indicated that GM-CSF is synthesized by epithelial cells in the murine pregnant and non-pregnant uterus. In this study, the(More)
Endometriosis is an adhesion disorder characterized by the presence of endometrial tissue in ectopic sites outside the uterus. The disease is associated with dysmenorrhea, pelvic pain and infertility. Although endometriosis is the most common gynecologic disorder, relatively little is known regarding its etiology, pathogenesis and the course of the disease.(More)
The effects of the antiestrogen tamoxifen (TAM) on the growth of two hormone-sensitive human tumors have been examined in athymic mice. The endometrial tumor, EnCa101, was stimulated to grow by TAM either alone or when combined with estradiol. This contrasted with the nonstimulation of the breast tumor, MCF-7, by TAM alone and the antagonist action of TAM(More)
Normal human endometrium expresses LH/hCG receptor gene. In the present study, we investigated whether human endometrial carcinomas also express this receptor gene. Reverse transcription-nested polymerase chain reaction amplified LH/hCG receptor sequences from human endometrial carcinoma just as it did those from normal human endometrium and human ovary as(More)
A simple method for isolation of glands from human endometrium has been developed. The procedure involves collagenase digestion of the endometrial tissue and filtration through sieves of various pore sizes. Isolated glands retained on the sieves were washed and collected in culture dishes. Tubular organization of the isolated glands was ascertained by(More)
Tamoxifen (TAM), a nonsteroidal antiestrogen, is used in the adjuvant treatment of breast cancer. Previous studies, however, have indicated that some human breast and endometrial tumors are stimulated to grow with TAM in the athymic mouse. One such TAM-stimulated tumor is the EnCa101 human endometrial adenocarcinoma. Our aim was to evaluate the ability of(More)
Endometrial progesterone receptors (PR) are regulated by both estrogen (E2) and progesterone (P) and mediate the expression of specific endometrial proteins. Ishikawa cells are a well-differentiated human endometrial adenocarcinoma cell line, with both estrogen receptors (ER) and PR, regulated in a manner similar to that of normal endometrium.(More)
To evaluate the usefulness of autoantibody detection as a nonoperative method of diagnosing endometriosis, we tested 221 sera from 215 patients from the infertility, gynecology, and gynecologic oncology services by an indirect immunofluorescence assay using monolayer cultures of an endometrial carcinoma cell line. The assay showed positive cytoplasmic(More)
