Pheochromocytoma in rats with multiple endocrine neoplasia (MENX) shares gene expression patterns with human pheochromocytoma

MENX is a rat multiple endocrine neoplasia syndrome caused by a homozygous mutation of the Cdkn1b gene, encoding p27Kip1. Affected rats develop adrenomedullary hyperplasia which progresses to pheochromocytoma with time (incidence 100%), and to extra-adrenal pheochromocytoma (paraganglioma) (68%).
