In vitro studies demonstrate that ERβ ligands inhibit the proliferation of melanoma cells harboring the NRAS (but not the BRAF) mutation, suggesting that ERβ activation might impair melanoma development through the inhibition of the PI3K/Akt pathway. 17β-estradiol was reported to inhibit melanoma cells proliferation however, clinical trials did not provide the expected survival benefits. Thus, ERβ is now considered as an effective molecular target for melanoma treatment. ERβ is the predominant ER in melanoma, and its expression decreases in melanoma progression, supporting its role as a tumor suppressor.
Estrogens exert their effects through estrogen receptors (ERα and ERβ) that affect cancer growth in an opposite way: ERα is associated with a proliferative action and ERβ with an anticancer effect. Melanoma incidence is higher in males than in females, and females have a significant survival advantage over men. Increasing evidence supports that melanoma is a hormone-related cancer. However, treatment resistance and side effects are common events of these therapeutic strategies. The current therapeutic approaches are based on therapies targeting mutated BRAF and the downstream pathway, and on monoclonal antibodies against the immune checkpoint blockade. Melanoma is a heterogeneous tumor, with most patients harboring mutations in the BRAF or NRAS oncogenes, leading to the overactivation of the MAPK/ERK and PI3K/Akt pathways. 2Department of Medical Biotechnologies and Translational Medicine, Università degli Studi di Milano, Milano, ItalyĬutaneous melanoma is an aggressive tumor its incidence has been reported to increase fast in the past decades.1Department of Pharmacological and Biomolecular Sciences, Università degli Studi di Milano, Milano, Italy.Roberta Manuela Moretti 1 and Patrizia Limonta 1* The PNG files have a transparent background.
