Granulosa cell-specific markers

Granulosa cell-specific markers represent a diverse suite of proteins, receptors, and enzymes exclusively or predominantly expressed by the granulosa cells of the ovarian follicles. Key members of this group include Anti-Müllerian Hormone (AMH), Inhibin A and B, the Follicle-Stimulating Hormone Receptor (FSHR), and the master transcription factor FOXL2. These molecules are essential for orchestrating ovarian folliculogenesis, regulating steroidogenesis (particularly the conversion of androgens to estrogens via aromatase), and maintaining the follicular microenvironment for oocyte development. In clinical oncology, these markers—specifically AMH and Inhibin B—are critical diagnostic and prognostic tools for Granulosa Cell Tumors (GCT), serving as sensitive indicators for disease monitoring and recurrence. In reproductive medicine, markers like AMH are used to assess ovarian reserve and predict response to controlled ovarian stimulation. While several markers are targeted therapeutically (e.g., FSHR by gonadotropins or aromatase by inhibitors), the category itself serves more as a biological classification than a single drug target. Emerging research also explores targeted therapies like multi-kinase inhibitors and progesterone receptor modulators for recurrent granulosa cell malignancies.
