Località: Pieve Emanuele, IT, 20090 Rozzano, IT, 20089 Research Program Title **Elucidating the pathomechanisms by which PAM mutations predispose to pituitary neuroendocrine tumors (PitNETs) formation** PI Giampaolo Trivellin Objectives of the research Background: Pituitary neuroendocrine tumors (PitNETs) impact health via hormonal hypersecretion and brain invasion, with most cases lacking known driver mutations. We recently identified germline mutations in the PAM gene in PitNET patients. PAM, a multifunctional protein, regulates hormone amidation and secretion, with altered expression linked to cancer mortality. Hypothesis: PAM defects predispose to PitNETs by disrupting its non-catalytic functions, unveiling a novel disease mechanism. Aims: We aim to elucidate how PAM loss drives pituitary tumorigenesis via three approaches:
1. Investigate how PAM mutations affect intracellular pathways and hormone secretion in tumor cell lines. 2. Study pituitary-specific PAM loss in mice to assess tumorigenesis and systemic effects. 3. Evaluate PAM staining as a biomarker in human PitNETs. Expected Results: Our findings will reveal PAM’s non-enzymatic roles in PitNET development, provide systemic insights, and assess PAM as a diagnostic/prognostic tool, advancing genetic testing and early diagnosis.
