Multiple Epigenetic Mechanisms Functionally Cooperate to Silence Expression of Somatostatin Receptor Type 2 in Pancreatic Neuroendocrine Tumors

James P. Madigan, Stephen G. Andrews, Rivka B. Farrell…·Samira Mercedes Sadowski

This study identifies multiple epigenetic mechanisms that silence SSTR2 expression in PNETs, highlighting the role of DNMT3B, PRC complexes, histone demethylases, and chromatin remodelers, with potential therapeutic implications.

Upregulation of Somatostatin Receptor Type 2 in a Receptor-Deficient In Vivo Pancreatic Neuroendocrine Tumor Model Improves Tumor Response to Targeted 177Lu-DOTATATE

Rupali Sharma, Bhargav Earla, Kwamena E. Baidoo…·Samira Mercedes Sadowski

This study shows that HDAC inhibitors increase SSTR2 expression in pancreatic neuroendocrine tumors, enhancing 177Lu-DOTATATE therapy efficacy in receptor-deficient models.
