#3997 FOXA2-initiated transcriptional activation of INHBA induced by methylmalonic acid promotes pancreatic neuroendocrine neoplasm progression

Introduction: More than 60% of pancreatic neuroendocrine neoplasms (PanNENs) represent metastases when diagnosed. Metabolic alterations have been recognized as one of the hallmarks of tumor metastasis. However, little is known about the molecular mechanism of metabolic changes regulating PanNEN progression.

#3987 m6A modifications promote the invasion and metastasis of pancreatic neuroendocrine neoplasms by activating the Integrin/FAK signalling pathway via TGFBI

Introduction: Nearly 50% of patients with pNENs have metastases at the time of initial diagnosis, and there is a lack of effective treatment once they have metastases. The 5-year overall survival rate for G3 pNENs with metastasis at diagnosis was 0, which was significantly lower than that for patients without metastasis, with a 5-year overall survival rate of 43%. At present, the pathogenesis of pNENs has not been clarified.

#3713 Methylmalonic acid activates INHBA induced epithelial-mesenchymal transition and promotes the cancer progression by TGF-β signalling pathway in pancreatic neuroendocrine neoplasm

Introduction: Metabolic reprogramming is a well-recognized hallmark of cancer progression, especially the process of tumor metastasis. However, the role of metabolic alteration and its potential mechanism in pancreatic neuroendocrine neoplasm (pNEN) with metastasis remain elusive.

#3622 Hypoxia down-regulates m6A methyltransferase METTL3 and WTAP promotes pancreatic neuroendocrine tumor metastasis via regulating TGFBI

Introduction: Hypoxia is a marker of cancer progression. When faced with hypoxia, tumor cells exhibit the dynamic change of N6-methyladenine (m6A). m6A is a reversible RNA modification that plays an important role in gene expression regulation and is closely related to the occurrence and development of various tumors.

#2920 Mutation Spectrums Analysis of Colorectal Adenocarcinoma and Neuroendocrine Neoplasm Based on Same Genetic Background to Reveal Tumorigenesis

Introduction: The tumorigenesis of neuroendocrine neoplasm (NEN) are still ambiguous. The therapies of NENs in colon or rectum refer to adenocarcinomas (AC) when tumor metastasis, but the response was unsatisfactory which inspired us to explore the mutation difference.
