It plays a pivotal role in oesophageal cancer and may act as a therapeutic target for this intractable malignancy. It has a novel role in oligodendroglioma proliferation and acts as a potential therapeutic alternative for oligodendrogliomas. Lower expression of ETB receptor responsiveness is associated with polycystic ovary syndrome (PCOS) and may reflect lower endothelial-mediated vasodilatation independent of generally lower vascular reactivity.
