Heterozygous mutant MENX rats as a novel model of invasive medullary thyroid carcinoma

As overwhelming evidence coming from transgenic mouse models but also from MEN4 patients seem to suggest that loss or inactivation of a single p27 allele plays an important role in neuroendocrine tumorigenesis, we decided to perform a detailed analysis of the phenotype of rats heterozygous for the MENX-associated germline Cdkn1b mutation.
