Purpose: Clinically Non-Functioning Pituitary Neuroendocrine Tumours (NF-PitNETs) present a varying degree of aggressiveness, and reliable prognostic markers are lacking. We aimed to characterize the distribution of E- and N-cadherin in corticotroph, PIT1 and null-cell NF-PitNETs, and link it to the clinical course of the tumours.Methods: We investigated the distribution of E- and N-cadherin by immunohistochemistry in a retrospective cohort of thirty tum...

Background: Real-time reverse transcription quantitative PCR (RT-qPCR) has become the method of choice for quantification of gene expression changes. Inappropriate data normalization and inconsistent data analyses are some limitations of RT-qPCR. Pituitary adenomas are frequent tumours and the interpretation of increasingly published data within this field is hindered by the lack of a proper selection and validation of stably expressed reference genes.Ai...
