AIM: Recent evidence has suggested the important implications of microRNAs (miRNAs) in the processes of proliferation and tissue remodeling in endometriosis (EMS). We therefore aim to determine the role of miR-202-3p in the pathophysiology …

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder in females of the reproductive age. PCOS is commonly manifested as ovulatory dysfunction, clinical and biochemical excess androgen level, and polycystic ovaries. Meta…

AIMS: Premature ovarian failure (POF) is a phenomenon in which the ovaries fail before the age of 40 years. Prior research has used a wide range of mouse models designed to reflect different causes of POF, including genetic factors, iatroge…

AIMS: Improving the environment of the injured area and the preconditioning of mesenchymal stem cells (MSCs) are promising approaches to optimize the therapeutic properties of transplanted MSCs. Herein we investigated the synergistic effect…

The alteration of PTEN expression may be a vital part of the pathological and physiological mechanisms in infertility-related with endometriosis. However, the potential mechanisms underlying abnormal expression of PTEN and its role in proge…

AIMS: Our study was designed to explore the function and mechanism of Tanshinone IIA in alleviating pain syndrome caused by endometriosis (EMs). MAIN METHODS: Female Sprague-Dawley rats went through autotransplantation operation to establi…

AIMS: Controversy surrounds the gender basis of progression in chronic kidney disease. Unfortunately, most experimental studies addressing this question do not distinguish between direct effects of estrogen and indirect activation of estrog…

AIMS: Suppression of the hypothalamic-pituitary-gonadal axis has been widely utilized for the management of gonadal-hormone-dependent diseases such as endometriosis. Efforts to develop orally available gonadotropin-releasing hormone (GnRH) …

AIMS: To characterize the biochemical alterations that occur in the peritoneal tissue of the mouse endometriosis model during early development of the lesion using microarray analysis. MAIN METHODS: The endometriosis model was induced by a…

Angiogenesis, the formation of new capillaries from preexisting vessels, plays an essential role in revascularization of the myocardium following myocardial infarction (MI). Interleukin-1beta (IL-1beta), a proinflammatory cytokine increased…

Many persistent pesticides have been implicated in reproductive and developmental adverse effects, in man and wildlife. It has been hypothesized that these so-called xeno-hormones could upset the endocrine system function by binding to huma…

Endometriosis is a gynaecological disorder characterized by the presence and growth of endometrial tissue in ectopic sites. In this study we examined the immunological functions of patients with endometriosis and serum level of PCBs and p,p…

Chinese herbs have been used to relieve dysmenorrhea associated with endometriosis. Active components in the herbs and their mechanisms of action remain unknown. Prunella stica, a Chinese herb commonly used to treat dysmenorrhea, was chosen…

Uterine adenomyosis is a disease in which hyperplastic endometrial stroma and glands invade the myometrium. We have previously demonstrated that hyperprolactinemia leads to the development of adenomyosis in mice. In the present study, a sub…

Like carcinoma, endometriosis has the unique characteristics, of invasion and metastasis, though pathologically, it is a benign tumor. However, the mechanism of destruction of the surrounding tissue in endometriosis is still unclear. In thi…

The possibility of therapeutic application of novel nonsteroidal progesterone receptor modulators CP8816 and CP8863 for preventing the development of uterine adenomyosis was investigated in mice. First priming effects of CP8816 on 17beta-es…

To assess the effect of pharmacological dose of melatonin on bone metabolism in ovariectomized rats, urinary deoxypyridinoline (a marker of bone resorption) and calcium excretion, circulating levels of calcium, phosphorus and bone alkaline …

Although transforming growth factor-alpha (TGF-alpha), one of the epidermal growth factor (EGF) family of growth factors, is expressed in the rat decidual cells, its roles in decidualization remain to be elucidated. This study examined the …

To evaluate the effects of mifepristone (RU486) on the development of uterine adenomyosis induced by pituitary grafting (PG), 3 groups of mice receiving pituitary grafts at 7 weeks of age were given RU486 in food (20 mg/kg chow) from 3-14 (…

To investigate changes in uterine prolactin receptor (PRLR) expression in advanced uterine adenomyosis induced by ectopic pituitary isograft, the amount of PRLR mRNA was measured, by a quantitative competitive PCR, in both normal uteri and …

The reproductive function of male and female rats with induced nephrotic syndrome was examined by assessing hormonal levels, the estrous cycle pattern and fertility. Measurements were carried out on day 10 (nephrotic stage) and on day 30 (r…

Components of the uterine fluid in mice with experimentally-induced adenomyosis and in controls were examined by proton nuclear magnetic resonance spectroscopy. One of the components was markedly different in mice with adenomyosis. As this …

The number of ovulation was significantly higher in hysterectomized rats with regular estrous cycles than in sham-operated rats at the estrous stage 20-24 days after operations (13.2 +/- 0.33 vs. 11.8 +/- 0.41, P < 0.05). This finding sugge…

Inhibitory effects of danazol, an isoxazol derivative of synthetic steroid 17 alpha-ethinyl-testosterone, on the development of uterine adenomyosis, a pathological disorder of endometrial tissue defined as the presence of endometrial glands…

Development of uterine adenomyosis was studied in SHN mice treated with psychotherapeutic drugs, sulpiride and perphenazine, and gastroenteric drug, metoclopramide, which act as dopamine antagonists to increase prolactin release from the pi…
