Abstract
Rabbit uterine cervical fibroblasts produced a large amount of matrix metalloproteinases (MMPs) such as collagenase (MMP-1) and stromelysin (MMP-3) and a small relatively amount of tissue inhibitor of metalloproteinases (TIMP). When cells were treated with progesterone or oestradiol-17 beta, both steroids concurrently decreased the level of procollagenase and prostromelysin in the culture media and the steady-state levels of the respective mRNAs. On the other hand, the level of TIMP in the culture media and the steady-state level of its mRNA were simultaneously increased by these steroids. Similarly, the suppression of production of MMPs and the augmentation of TIMP production by both steroids were observed with interleukin 1 (IL-1)-treated cells, but the action of progesterone was more effective than that of oestradiol-17 beta in the IL-1-untreated and -treated cells. These results suggest that collagenolysis in uterine cervical fibroblasts is negatively regulated by steroid hormones via the acceleration of TIMP production and the suppression of synthesis of MMPs at the pretranslational level.
It is now accepted that gelatinase B (92 kd type IV collagenase) is involved in blastocyst implantation and trophoblast invasion. However, little is known about the regulation of this enzyme at the fetomaternal interface. Progesterone has been demonstrated to inhibit gelatinase B secretion from endometrial cells, myometrium, and cervical fibroblasts. Interestingly, the promotor of gelatinase B contains a progesterone-responsive element that may explain transcriptional activation of this metalloproteinase by progesterone. It may be hypothesized that progesterone secreted from trophoblast cells, representing the fetal part of the fetomaternal interface, may have a role in the regulation of gelatinase secretion and blastocyst implantation. To this end, use was made of first-trimester trophoblast cells obtained from first-trimester pregnancy terminations. The trophoblast cells were separated by trypsin degradation and fractionation on Percoll gradients. Metalloproteinase activity was measured by zymography, and the expression of the gelatinase B messenger ribonucleic acid was determined by the solution hybridization/ribonuclease protection assay. Primary cell cultures of trophoblasts from first trimesters of pregnancy constitutively elaborated two species of type IV collagenases (gelatinase A and B) as assessed on a gelatin matrix. Treatment with progesterone decreased the accumulation of a gelatinase B species in a dose-dependent fashion. Administration of a progesterone receptor antagonist onapristone (ZK-98.299) neutralized the progesterone inhibitory effect on the gelatinase B in a dose-dependent fashion, thus supporting the presumption that the progesterone effect is receptor mediated. Progesterone significantly attenuated the expression of gelatinase B by trophoblast cells, an effect that was neutralized by ZK-98.299. These observations provide strong indirect support for the participation of progesterone in the regulation of gelatinase B in trophoblast cells. It may be an important regulator of gelatinase production at the fetomaternal interface.
Microsomal membranes sedimented at 40 000 g were prepared from human myometrium samples. The progesterone binding properties of microsomal suspensions were determined by incubating microsomes and [3H]progesterone at 4 degrees C. Dextran-coated charcoal was used for the separation of bound and free steroids. Membrane-associated progesterone binding sites of high affinity were identified in microsomes prepared from pregnant and nonpregnant uteri. The binding was saturable (Kd approximately 4 X 10(-9) M, concentration of binding sites 400-900 fmol/mg microsomal protein) and specific for natural progesterone. Of 21 steroids tested only 21-hydroxy-4-pregnene-3,20-dione, 17 alpha-hydroxyprogesterone and testosterone showed moderate competition against progesterone with relative affinities between 7.0-20.0% (R.A. of progesterone 100%). 5 alpha-Dihydroprogesterone and 5 alpha-dihydrotestosterone showed weak cross reaction (relative affinities 2.5 and 2.0%, respectively). Corticosteroids, estrogens and the 5 synthetic progestins tested showed only weak competition with relative affinities lower than 1.0%. These microsomal progesterone binding sites of high affinity and limited capacity resemble steroid hormone receptors but they are different from the soluble cytosolic progesterone receptor of human uterus in terms of steroid specificity. The physiological function of this microsomal progesterone receptor is unknown.

Estrogen and progesterone and their signaling mechanisms are tightly regulated to maintain a normal menstrual cycle and to support a successful pregnancy. The imbalance of estrogen and progesterone disrupts their complex regulatory mechanisms, leading to estrogen dominance and progesterone resistance. Gynecological diseases are heavily associated with dysregulated steroid hormones and can induce chronic pelvic pain, dysmenorrhea, dyspareunia, heavy bleeding, and infertility, which substantially impact the quality of women's lives. Because the menstrual cycle repeatably occurs during reproductive ages with dynamic changes and remodeling of reproductive-related tissues, these alterations can accumulate and induce chronic and recurrent conditions. This review focuses on faulty progesterone signaling mechanisms and cellular responses to progesterone in endometriosis, adenomyosis, leiomyoma (uterine fibroids), polycystic ovary syndrome (PCOS), and endometrial hyperplasia. We also summarize the association with gene mutations and steroid hormone regulation in disease progression as well as current hormonal therapies and the clinical consequences of progesterone resistance.

Semen liquefaction changes semen from a gel-like to watery consistency and is required for sperm to gain mobility and swim to the fertilization site in the Fallopian tubes. Kallikrein-related peptidases 3 (KLK3) and other kallikrein-related peptidases from male prostate glands are responsible for semen liquefaction by cleaving gel-forming proteins (semenogelin and collagen). In a physiological context, the liquefaction process occurs within the female reproductive tract. How seminal proteins interact with the female reproductive environment is still largely unexplored. We previously reported that conditional genetic ablation of Esr1 (estrogen receptor α) in the epithelial cells of the female reproductive tract (Wnt7aCre/+;Esr1f/f) causes female infertility, partly due to a drastic reduction in the number of motile sperm entering the oviduct. In this study, we found that post-ejaculated semen from fertile wild-type males was solidified and the sperm were entrapped in Wnt7aCre/+;Esr1f/f uteri, compared to the watery semen (liquefied) found in Esr1f/f controls. In addition, semenogelin and collagen were not degraded in Wnt7aCre/+;Esr1f/f uteri. Amongst multiple gene families aberrantly expressed in the absence of epithelial ESR1, we have identified that a lack of Klks in the uterus is a potential cause for the liquefaction defect. Pharmacological inhibition of KLKs in the uterus replicated the phenotype observed in Wnt7aCre/+;Esr1f/f uteri, suggesting that loss of uterine and seminal KLK function causes this liquefaction defect. In human cervical cell culture, expression of several KLKs and their inhibitors (SPINKs) was regulated by estrogen in an ESR1-dependent manner. Our study demonstrates that estrogen/ESR1 signaling in the female reproductive tract plays an indispensable role in normal semen liquefaction, providing fundamental evidence that exposure of post-ejaculated semen to the suboptimal microenvironment in the female reproductive tract leads to faulty liquefaction and subsequently causes a fertility defect.
