The Orphan Nuclear Receptors Steroidogenic Factor-1 and Liver Receptor Homolog-1: Structure, Regulation, and Essential Roles in Mammalian Reproduction.

Physiol Rev 2019 04;99(2):1249-1279

Centre de Recherche en Reproduction et Fertilité, Université de Montréal, St-Hyacinthe, Québec , Canada.

Nuclear receptors are intracellular proteins that act as transcription factors. Proteins with classic nuclear receptor domain structure lacking identified signaling ligands are designated orphan nuclear receptors. Two of these, steroidogenic factor-1 (NR5A1, also known as SF-1) and liver receptor homolog-1 (NR5A2, also known as LRH-1), bind to the same DNA sequences, with different and nonoverlapping effects on targets.

[Sex cord-stromal tumors of the ovary : Current aspects with a focus on granulosa cell tumors, Sertoli-Leydig cell tumors, and gynandroblastomas].

Authors:
F Kommoss H-A Lehr

Pathologe 2019 Feb;40(1):61-72

Institut für Pathologie, Medizin Campus Bodensee, Röntgenstr. 2, 88048, Friedrichshafen, Deutschland.

Sex cord-stromal tumors of the ovary (SCSTO) comprise a heterogeneous and fascinating group of neoplasms with diverse clinicopathological features, including benign lesions as well as tumors with malignant potential. Clinically, SCSTO may be associated with hyperestrogenic or androgenic function as a result of steroid hormone production by the tumor cells.Histological diagnosis may be challenging due to complex and sometimes overlapping morphological features of the various tumor types.

Hepatoid Carcinoma of the Ovary: Clinical, Histopathologic, and Immunophenotypic Features.

Arch Pathol Lab Med 2019 Jan 10. Epub 2019 Jan 10.

From the University of Illinois at Chicago (Dr Acosta); the Chicago Medical School of Rosalind Franklin University of Medicine and Science, North Chicago, Illinois (Dr Pins); and the Advocate Lutheran General Hospital and the James R. & Helen D. Russell Institute for Research & Innovation, Park Ridge, Illinois (Dr Pins).

Hepatoid carcinoma of the ovary (HCO) is a rare malignant tumor of uncertain histogenesis that was first described by Ishikura and Scully in the late 1980s. Unlike hepatoid yolk sac tumor (HYST), one of its main differential diagnoses, HCO usually presents in perimenopausal and postmenopausal women without gonadal dysgenesis. Most cases show advanced local disease at initial presentation, with diffuse intraperitoneal dissemination. Read More

Department of Radiology, Osaka Medical College, 2-7 Daigaku-machi, Takatsuki City, Osaka, 569-8686, Japan.

Background: Ovarian granulosa cell tumors (GCTs) are divided into adult GCT (AGCT) and juvenile GCT (JGCT). The AGCT is more common type, conversely, less than 5% of tumors are the JGCT and occur in mainly premenarchal girls and in women younger than 30 years. Although JGCT have different histologic features compared to AGCT, the two types have similar imaging features because they have similar gross appearance. Read More

Persistent endocrine-disrupting chemicals found in human follicular fluid stimulate the proliferation of granulosa tumor spheroids via GPR30 and IGF1R but not via the classic estrogen receptors.

Chemosphere 2019 Feb 4;217:100-110. Epub 2018 Nov 4.

Department of Physiology and Toxicology of Reproduction, Institute of Zoology and Biomedical Research, Jagiellonian University, Gronostajowa 9, 30-387 Krakow, Poland. Electronic address:

Epidemiological studies have found that women have detectable levels of organic pollutants such as hexachlorobenzene (HCB), 2,2-dichlorodiphenyldichloroethylene (p,p'-DDE), polychlorinated biphenyl 153 (PCB153), perfluorooctanoate (PFOA), and perfluorooctane sulfonate (PFOS) in their follicular fluid. Thus, these compounds may directly affect the function of granulosa cells within the ovary and may promote granulosa cell tumor (GCT) progression. Two human GCT cell lines, COV434 and KGN, have been used as in vitro model systems to represent juvenile (JGCT) and adult (AGCT) GCT subtypes, respectively. Read More

Electronic address:

Anti-Müllerian hormone (AMH), known for its role during sexual differentiation, is a dimeric glycoprotein that belongs to the transforming growth factor-β (TGF-β) family. AMH has recently been identified as a reliable marker of ovarian reserve that can help predict early ovarian follicle loss and menopause onset. AMH levels also reflect the effects of damaging gynecologic surgeries or gonadotoxic treatments such as chemotherapy on ovarian reserve. Read More

Department of Cellular and Organ Pathology, Graduate School of Medicine, Akita University, Akita 010-8543, Japan.

In the female genital tract, extrauterine leiomyomas such as those that arise in the ovary and paraovarian/paratubal regions are rare. Currently, little is known about the background genetic changes in such adnexal leiomyomas. Recent studies have found that the MED12 mutation is common in uterine leiomyomas, which suggests that such mutations may play an oncogenic role in smooth muscle neoplasms in females. Read More

What Is Known Already: In an earlier study, we demonstrated that constitutively active TGFB receptor 1 (TGFBR1) in ovarian somatic cells promotes the development of ovarian GrCTs. However, the consequence of dysregulation of TGFB signaling in the pathobiology of the testis, remains poorly defined. Read More

TERT promoter mutation in adult granulosa cell tumor of the ovary.

Mod Pathol 2018 07 15;31(7):1107-1115. Epub 2018 Feb 15.

Department of Molecular Oncology, British Columbia Cancer Agency, Vancouver, BC, Canada.

The telomerase reverse transcriptase (TERT) gene is highly expressed in stem cells and silenced upon differentiation. Cancer cells can attain immortality by activating TERT to maintain telomere length and telomerase activity, which is a crucial step of tumorigenesis. Two somatic mutations in the TERT promoter (C228T; C250T) have been identified as gain-of-function mutations that promote transcriptional activation of TERT in multiple cancers, such as melanoma and glioblastoma.
