Summary of "MicroRNA-486-5p inhibits ovarian granulosa cell proliferation and participates in the development of PCOS via targeting MST4."

To explore whether microRNA-486-5p affected the proliferation of ovarian granulosa cells by targeting MST4 (silk/threonine protein kinase 4), thereby promoting the development of polycystic ovary syndrome (PCOS).

Timely expression and activation of YAP1 in granulosa cells is essential for ovarian follicle development.

Although the role of the Hippo signaling pathway in development and tumorigenesis has been extensively studied in multiple organs, its role in ovarian follicle development remains largely unknown. Her...

LncSNHG14 promotes ovarian cancer by targeting microRNA-125a-5p.

This study aims to investigate whether small nucleolar RNA host gene 14 (SNHG14) is involved in the development of ovarian cancer through affecting cell proliferation and cell cycle progression by reg...

Estrogen regulates forkhead transcription factor 2 to promote apoptosis of human ovarian granulosa-like tumor cells.

Granulosa cell tumors of the ovary (GCTs) are the predominant form of ovarian stromal tumors and can lead to abnormally secreted estrogen hormones. Studies have reported that forkhead transcription fa...

Role of nuclear factor-κB pathway in the transition of mouse secondary follicles to antral follicles.

Nuclear factor-κB (NF-κB) signaling is involved in regulating a great number of normal and abnormal cellular events. However, little is known about its role in ovarian follicular development. In thi...

The phytoestrogen, diosgenin, directly stimulates ovarian cell functions in two farm animal species.

Medical and Biotech [MESH] Definitions

A cyclin D subtype which is regulated by GATA4 TRANSCRIPTION FACTOR. Experiments using KNOCKOUT MICE suggest a role for cyclin D2 in granulosa cell proliferation and gonadal development.

A forkhead box transcription factor that is expressed in the developing eyelid and during very early development of the gonad, prior to sex determination. It is essential for development of the ovary and inhibits SOX9 TRANSCRIPTION FACTOR to prevent differentiation to testes. It also induces APOPTOSIS in ovarian cells. Mutations in the FOXL2 gene are associated with BLEPHAROPHIMOSIS; Ptosis, and Epicanthus inversus (BPES with ovarian failure).

A B7 antigen subtype that inhibits the costimulation of T-cell activation, proliferation, cytokine production and development of cytotoxicity. The over expression of this protein in a variety of tumor cell types suggests its role in TUMOR IMMUNE EVASION.

Supporting cells for the developing female gamete in the OVARY. They are derived from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the OOCYTE in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the OVUM in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors (RECEPTORS, LH).

A neoplasm composed entirely of GRANULOSA CELLS, occurring mostly in the OVARY. In the adult form, it may contain some THECA CELLS. This tumor often produces ESTRADIOL and INHIBIN. The excess estrogen exposure can lead to other malignancies in women and PRECOCIOUS PUBERTY in girls. In rare cases, granulosa cell tumors have been identified in the TESTES.
