Background: BCL-2 is an anti-apoptotic protein associated with resistance to tumor cell death and is a histopathologic marker of neuroendocrine differentiation. We characterized the transcriptomic profile of BCL2 expression in NENs and its association with site, immune infiltration, and overall survival (OS).Methods: Next-generation sequencing of both DNA (592-gene panel or whole exome) and RNA (whole transcriptome) was performed on NENs of pancreatic (P...

Background: SSTR substypes are collectively expressed in the majority of NENs. However, SSTR subtype expression is not routinely assessed for clinical decision-making, including patients eligible for targeted radionucleotide therapy. Elucidating the landscape of SSTR subtypes in context of molecular profiles for low-grade (LG-) and high-grade NENs (HG-NENs) provides an opportunity to better tailor targeted therapy. Here, we leverage the ability of transcriptomics to predict NE...

Background: Significant advances have been made in the treatment of gastrointestinal (GI-) and pancreatic (P-) NENs. However, the use of immunotherapy is still limited, with most tumors considered immune “cold”. The cGAS-STING signaling pathway has emerged as a critical mediator of inflammation and immune-mediated responses, with pathway agonists under development for enhancing immunotherapy. In this study, we evaluated associations between cGAS-STING pathway activit...
