In this study, the neurotrophin tyrosine receptor kinase TrkA (also called NTRK1), the common neurotrophin receptor p75<sup>NTR</sup>, and the proneurotrophin receptor sortilin were analyzed with immunohistochemistry in a cohort of thyroid cancers (n = 128) and compared with adenomas and normal thyroid tissues (n = 62).
NTR3 mRNA expression was observed in all examined samples and was higher in the adenomas, both functioning and nonfunctioning, compared to normal pituitary.
