#3512 Genetic, epigenetic and/or transcriptional profiling of 14q genes, MAX and MEG3 in pituitary neuroendocrine tumors

Introduction: Recent studies have identified a growing series of susceptibility genes for pituitary neuroendocrine tumors (PitNETs) and pheochromocytomas/paragangliomas (PPGL). Some of these genes (e.g., SDH genes) have be specifically associated with the development of these pathologies.

#3505 DRD2 agonist cabergoline abolished the escape mechanism induced by mTOR inhibitor everolimus in pituitary neuroendocrine tumoral cells

Introduction: The mTOR inhibitor everolimus displays antimitotic effects on diverse neoplasms, including pituitary neuroendocrine ones (PitNETs); however, its effect is reduced by an escape mechanism that increases AKT phosphorylation (p-AKT) leading to survival pathway activation. Dopamine receptor type 2 (DRD2) reduces p-AKT in some non-functioning PitNETs (NF-PitNETs) and in lactotrophs MMQ cells, through a β-arrestin2-dependent mechanism.
