Nuclear receptor subfamily 0 group B member 1 (Nr0b1) is an atypical member of the nuclear receptor family that is predominantly expressed in mouse Sertoli cells (SCs). Mutations of NR0B1 in humans cause adrenal failure and hypogonadotropic hypogonadism. The targeted mutagenesis of Nr0b1 in mice has revealed a primary gonadal defect characterized by the overexpression of aromatase and cellular obstruction of the seminiferous tubules and efferent ductules, leading to germ cell death and infertility. The transgenic expression of Nr0b1 under the control of the Müllerian-inhibiting substance promoter (MIS-Nr0b1), which is selectively expressed in SCs, improves fertility...

Undescended testes (UDTs) are a relatively common finding in newborn males, especially in those born prematurely. Upon discovering a non-intrascrotal testis, it is important to determine whether the testis is palpable or non-palpable and whether the finding is unilateral or bilateral. Imaging should not be used in this workup, as no current modality has been shown to be adequately sensitive or specific to aid in management decisions. Patients with UDTs diagnosed after 6 months of age should be referred to a specialist for correction so that surgery may be performed within 1 year thereafter...

BACKGROUND: Anti-Müllerian hormone (amh) or Müllerian-inhibiting substance (mis) is a member of the transforming growth factor-β family of hormones. This gene plays a key role in vertebrate male sex-determination by inhibiting the development of the Müllerian ducts, and has been shown to be the master sex-determinant in the Patagonian pejerrey. RESULTS: In the lingcod, Ophiodon elongatus, both males and females share one copy of amh, however we have identified a second duplicate copy that appears solely in the male individuals...

Nonylphenols (NPs) are considered as important environmental toxicants and potential endocrine disrupting compounds which can disrupt male reproductive system. 4-[1-Ethyl-1-methylhexy] phenol (4-NP65 ) is one of the main isomers of technical nonylphenol mixtures. In the present study, effect of NPs was evaluated from an isomer-specific viewpoint using 4-NP65 . Decreased mRNA expression levels of estrogen receptor (ER)-α, ER-β, androgen receptor (AR) and progesterone receptor (PR) were observed in the cells exposed to 4-NP65 for 24 h...

INTRODUCTION: Anti-Mullerian Hormone (AMH) is a glycoprotein of the transforming growth factor-β (TGF-β) family that seems to reflect the continuous non-cyclical growth of small follicles and can be considered an indirect index of the size of the resting primordial follicle pool. Accordingly, AMH represents a marker of Ovarian Reserve (OR) and is particularly useful in demonstrating ovarian tissue damage induced by chemotherapy. AIM: To evaluate and compare the levels of AMH in Breast Carcinoma patients before and after chemotherapy with age matched healthy controls and to assess whether AMH as a biochemical marker of the OR might improve prediction of chemotherapy related outcomes in these patients...

The MIS pathway is a potential therapeutic target in epithelial ovarian cancer (EOC): signaling requires both type II (T2R) and type I receptors (T1R), and results in growth inhibition. MISR2 is expressed in EOC, but the prevalence and relative contributions of candidate T1R remain unknown. We sought to: a) determine expression of T1R in EOC; b) assess impact of T1R expression with clinical outcomes; c) verify MIS-dependent Smad signaling and growth inhibition in primary EOC cell cultures. Tissue microarrays (TMA) were developed for analysis of T1Rs (ALK2/3/6) and MISR2 expression...

PURPOSE: This study aimed to investigate whether Müllerian inhibiting substance (MIS) in combination with calcitriol modulates proliferation and apoptosis of human ovarian cancer (OCa) cell lines (SKOV3, OVCAR3, and OVCA433) and identify the signaling pathway by which MIS mediates apoptosis. MATERIALS AND METHODS: OCa cell lines were treated with MIS in the absence or presence of calcitriol. Cell viability and proliferation were evaluated using the Cell Counting Kit-8 assay and apoptosis was evaluated by DNA fragmentation assay...

Predisposition to breast and extrauterine Müllerian carcinomas in BRCA1 mutation carriers is due to a combination of cell-autonomous consequences of BRCA1 inactivation on cell cycle homeostasis superimposed on cell-nonautonomous hormonal factors magnified by the effects of BRCA1 mutations on hormonal changes associated with the menstrual cycle. We used the Müllerian inhibiting substance type 2 receptor (Mis2r) promoter and a truncated form of the Follicle stimulating hormone receptor (Fshr) promoter to introduce conditional knockouts of Brca1 and p53 not only in mouse mammary and Müllerian epithelia, but also in organs that control the estrous cycle...

Orexin A (OXA), a hypothalamic neuropeptide, and its receptor (OX1R) are primarily expressed in lateral hypothalamus and are involved in the control of various biological functions. Expressions of OXA and OX1R have also been reported in peripheral organs like gastrointestinal and genital tracts. In the present study, expressions of OXA and OX1R have been observed in the testis of Parkes strain neonatal mice by semi-quantitative RT-PCR and western blot analyses. Immunohistochemical study also revealed their presence on spermatogonia, Sertoli cells and in the interstitium of the testis...

Plasma anti-Müllerian hormone (AMH) concentrations have been recently found to be predictive of the number of embryos recovered after FSH superovulatory treatment in the cow. However, the sensitivity of the Active Müllerian-inhibiting substance/AMH ELISA (ref. 10-14400; DSL-Beckman-Coulter) used to make these measurements in bovine plasma samples is low because it was developed to measure human AMH levels. To overcome this limitation, we developed an immunoassay specific for the bovine (B), ovine (O), and caprine (C) species, the bovine-ovine-caprine (BOC) ELISA...

To improve ovarian cancer patient survival, effective treatments addressing chemoresistant recurrences are particularly needed. Mullerian inhibiting substance (MIS) has been shown to inhibit the growth of a stem-like population of ovarian cancer cells. We have recently engineered peptide modifications to human MIS [albumin leader Q425R MIS (LRMIS)] that increase production and potency in vitro and in vivo. To test this novel therapeutic peptide, serous malignant ascites from highly resistant recurrent ovarian cancer patients were isolated and amplified to create low-passage primary cell lines...

BACKGROUND: Müllerian inhibiting substance, also called anti-Müllerian hormone (AMH), belongs to the TGF-alpha family and plays a key role during sexual development. Various reports have underlined expression of AMHRII in human gynecologic cancers including ovarian cancers (OC). Based on these considerations, a humanized glyco-engineered monoclonal antibody (3C23K) specific to AMHRII has been developed. In this study, we have assessed AMHRII expression in a panel of OC patient-derived xenografts (PDXs) and evaluated in vivo efficacy of 3C23K...

Müllerian inhibiting substance (MIS) has been shown to inhibit growth of a number of tumors in vitro and/or in vivo, but the downstream pathways which it regulates are not fully understood. In the present study we show that MIS type II receptor was highly expressed in AN3CA cells, a cell line derived from human endometrial cancer cell in which MIS-treatment caused a reduction of cell viability, and induced cellular apoptosis and genes involved cell cycle arrest. To understand the genome-wide effects of MIS on gene regulation, we performed serial gene expression analyses from 0 to 96 h at 24 h intervals after treating AN3CA cells with MIS...

Ovarian cancer has the highest mortality rate among gynecologic malignancies. The monoclonal antibody 12G4 specifically recognizes the human Müllerian inhibiting substance type II receptor (MISRII) that is strongly expressed in human granulosa cell tumors (GCT) and in the majority of human epithelial ovarian cancers (EOC). To determine whether MISRII represents an attractive target for antibody-based tumor therapy, we first confirmed by immunohistochemistry with 12G4 its expression in all tested GCT samples (4/4) and all, but one, EOC human tissue specimens (13/14)...

Müllerian inhibiting substance (MIS), also called anti-Müllerian hormone (AMH), is a member of the transforming growth factor-β super-family of growth and differentiation response modifiers. It is produced in immature Sertoli cells in male embryos and binds to MIS/AMH receptors in primordial Müllerian ducts to cause regression of female reproductive structures that are the precursors to the fallopian tubes, the surface epithelium of the ovaries, the uterus, the cervix, and the upper third of the vagina...

BACKGROUND: Detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of FSH is one of the most important goals in assisted reproductive technique (ART). OBJECTIVE: To evaluate whether high level of anti-mullerian hormone level is related to success of ART in patients with temporarily or consistently elevated early follicular phase serum levels of FSH. MATERIALS AND METHODS: Sixty three women underwent intracytoplasmic sperm injection (ICSI) with GnRH-agonist long protocol or intrauterine insemination (IUI) in a prospective cohort study...

Whereas in all other vertebrates the Müllerian ducts of genetic males are aborted during development, under the influence of Müllerian-inhibiting substance, in the caecilian amphibians they are retained as a pair of functional glands. It has long been speculated that the Müllerian gland might be the male accessory reproductive gland but there has been no direct evidence to this effect. The present study was undertaken to determine whether the caecilian Müllerian gland secretory proteins would bear antigenic similarity to secretory proteins of the prostate gland and/or the seminal vesicles of a mammal...

Persistent mullerian duct syndrome (PMDS) is usually an accidental finding either during orchipexy or during routine inguinal hernia repair in male patients presenting with maldescended or crytorchid testes. It is caused by a defect in the mullerian inhibiting substance system. Intraoperatively, mullerian remnants consisting of an infantile uterus and fallopian tubes are usually found. Familiarity with PMDS is necessary to diagnose the condition. We report a case of PMDS in a 14-year-old male presenting with bilateral undescended testes...

Mullerian Inhibiting Substance (MIS) has been shown to inhibit ovarian cancer cells both in-vitro and in-vivo. Furthermore, recent evidence suggests that MIS may effectively target a putative ovarian cancer progenitor cell population enriched by a panel of CD44+, CD24+, Ep-CAM+, and E-cadherin-cell surface markers. In order to accommodate clinical testing of MIS in ovarian cancer patients, the production of recombinant human MIS must be optimized to increase yield and purity. Here we show that, compared to wild type, the substitution of the MIS leader sequence to that of human serum albumin, combined with a modification of the endogenous cleavage site from RAQR/S to a furin/kex2 RARR/S consensus site results in high expression, increased C-terminus cleavage and a reduction in unwanted cryptic internal cleavage products when produced in CHO cells...

Each year, ∼25 000 women are newly diagnosed with ovarian cancer in the USA. The vast majority (>90%) of cases are of epithelial origin. This highly lethal cancer carries a mortality rate of >50% and a high risk of recurrence after conventional, first-line chemotherapy. Müllerian-inhibiting substance (MIS) is a gonadal hormone that causes regression of the Müllerian ducts. A series of studies have demonstrated that MIS also has multiple extra-Müllerian functions including inhibition of epithelial ovarian cancer cells in vitro and in vivo...
