Project description:Neuroendocrine neoplasms of the gallbladder and liver occur rarely in dogs and humans. A recent reclassification of human neuroendocrine neoplasms by the World Health Organization has refined categorization of these tumors by morphology, replicative indices, and molecular signatures. In humans, these factors correlate with survival outcomes. Improved characterization of these tumors is needed in dogs to identify diagnostic biomarkers and determine therapeutic strategies. To achieve this objective, the proteome of 3 canine hepatobiliary neoplasms was compared to normal canine adrenal and liver tissue from formalin-fixed paraffin-embedded samples. Thirty-two upregulated and 121 downregulated differentially expressed proteins were identified in the hepatobiliary neuroendocrine neoplasm samples. Among the upregulated proteins is galectin-1, a multivalent carbohydrate binding protein known to play a role in lung and pancreatic neuroendocrine neoplasia development and progression in humans. Drugs targeting the galectin family have shown promise as anticancer therapeutics in cervical cancer, prostate cancer, lung and pancreatic neuroendocrine neoplasia in human medicine. Galectin-1 may represent a novel treatment target in hepatobiliary neuroendocrine neoplasia in both humans and dogs.

Project description:<p>Pancreatic neuroendocrine tumors (PNETs), often referred to as "islet cell tumors", are neuroendocrine neoplasms that arise from cells of the endocrine and nervous system within the pancreas. These rare tumors which originate from the pancreatic islet are divided into many categories and are often classified by the hormone most strongly secreted. With the collaboration of the Elkins Pancreatic Center, the Human Genome Sequencing Center (HGSC) at Baylor College of Medicine had access to approximately 30 untreated tumor specimens and matched normal blood samples. Since the onset and progression of cancer is driven by extensive mutation of the genome, we are combining enrichment of exonic DNA with next generation sequencing to detect and characterize the somatic mutation profile of patients with pancreatic neuroendocrine cancer.</p> <p>This work was done at the Human Genome Sequencing Center (HGSC) in collaboration with the Elkins Pancreatic Center at Baylor College of Medicine in Houston, TX and was supported by grant number 5U54HG003273 from National Human Genome Research Institute (NHGRI).</p>

Project description:Pancreatic neuroendocrine tumors (PanNETs) account for 1-3% of all neoplasms of the pancreas. Epigenetic changes seem to be the main drivers of PanNET tumorigenesis. Indeed, the most frequent mutated genes in PanNETs are DAXX (Death domain associated protein 6), ATRX (Transcriptional Regulator ATRX) and MEN1 (menin 1), which are all involved in epigenetic regulation. The objective of the project is to study the epigenetic changes undergoing in PanNETs. Specifically, we aimed at investigating whether do exist biologically important epigenetic differences in PanNET, useful for a clinically relevant classification.

Project description:Pancreatic Neuroendocrine Neoplasms (PanNENs) are two subclasses: the well-differentiated, low to high-grade Pancreatic Neuroendocrine Tumors (PanNETs) and the poorly-differentiated, high-grade Pancreatic Neuroendocrine Carcinomas (PanNECs). DNA methylation and sequencing was performed for 57 PanNEN samples to decipher distinct methylation profiles separating PanNENs. Our study provides a robust and clinically applicable method to clearly distinguish PanNECs from PanNETG3s and improve patient stratification.
