In line with our results, N-cadherin has been shown to be expressed in other tumor types from neural crest/neuroendocrine cells origin such as astrocytomas [38], Merkel cell carcinoma [39] and pheochromocytomas and adrenal tumors [40] as well as in our recent study in gastroenteropancreatic neuroendocrine tumors [41]. Here, CDH2 is linked to pheochromocytoma.
