Abstract:
Granulosa cell tumors (GCTs) are rare ovarian tumors comprising an adult and a juvenile subtype. They have a generally good prognosis, but the survival rate drastically declines in patients with late-stage or recurring tumors. Due to the rarity of GCTs, the tumor type is largely understudied and lacks a specific treatment strategy. Estrogen receptor beta (ERβ/ESR2) has been found to be highly expressed in GCTs, which could be of therapeutic importance since it can be targeted with small molecules. However, its role in GCTs is not known. In this review, we summarize the current knowledge about the action of ERβ in the ovary and discuss its prospective role in GCTs.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
