The pathogenesis of gonadotrophin secreting pituitary tumours (gonadotrophinomas) remains poorly understood. BMP2, known to be important in the control of cell proliferation and differentiation, is essential for commitment of undifferentiated pituitary cells to the gonadotroph cell lineage. Attenuation of its expression is critical in allowing terminal differentiation. BMPs are associated with up-regulated expression of Id (Inhibitors of differentiation) proteins with predicte...
