#4209 Transcriptomic and spliceosomic landscapes of pancreatic neuroendocrine tumors generated through Oxford Nanopore Technology sequencing

Introduction: Pancreatic Neuroendocrine tumors (PanNETs) are rare neoplasms with heterogenous nature, still poorly understood. Their low mutational burden has prompted to explore other molecular aspects, from epigenomics to transcriptomics. Increasing evidence indicates that transcriptomic changes, often derived from alterations in alternative splicing, can generate isoforms with oncogenic potential. In this context, long-read Oxford Nanopore Technology (ONT) has emerged as an ideal suited sequencing tool to deeply study transcriptomics and splicing variants.

#4206 Specific spliceosomic landscapes reveal a possible link between RNA processing and panNETs behaviour

Introduction: Pancreatic Neuroendocrine Tumors (PanNETs) are characterized by a low number of mutations. Despite genomics, transcriptomics and epigenomics studies have helped to understand the molecular features of PanNETs, there is still a vast unexplored ground for better comprehension of this disease. In this context, we have previously documented that RNA splicing is dysregulated in these tumors, which unveils new avenues to discover potential biomarkers and therapeutic targets. However, clinical and molecular implications of this dysregulation are still very poorly understood.

#2745 Integrative Genomic Characterization Identifies Molecular Subtypes of Lung Carcinoids

Introduction: Lung carcinoids (LCs) are rare and slow growing primary lung neuroendocrine tumors. The WHO classify LCs into atypical and typical carcinoids. Recent studies have shown that the reproducibility of LCs classification and its prognostic efficacy have high interobserver variability
