#4490 Parietal cell-selective Slc26a9 deletion in mice causes gasdermin D mediates mitochondrial damage and pyroptosis, which is the key event to induce autoimmune gastritis

Introduction: Autoimmune gastritis (AIG) is the basis of gastric malignancy, including neuroendocrine tumour (NET) and gastric cancer (GC). We reported that Slc26a9 is highly expressed in parietal cells (PCs), and its deficiency caused GC.

#4473 Somatostatin analogue delayed the recrudescence of stomach NET: A real-world study

Introduction: Type 1 gastric NENs (g-NENs) are common and relapse easily. Somstostatin analogues (SSAs) can inhibit gastrin secretion and cell proliferation. While the usage of SSAs in g-NENs is still controversial.

#4415 MGMT-activated DUB3 stabilises Nrf2/NCOA4 to modulate apoptosis and ferroptosis, driving temozolomide resistance in pancreatic neuroendocrine tumours

Introduction: O6-methylguanine DNA methyltransferase (MGMT) is a key DNA repair enzyme that removes methyl groups from O(6)-alkylguanine in DNA, introduced by temozolomide (TMZ). Clinical studies in pancreatic neuroendocrine tumours (PanNETs) have confirmed its role in TMZ efficacy.

#4397 DNA repair enzyme regulation strategy for enhanced pancreatic neuroendocrine tumour therapy via targeting siRNA-lipid nanoparticles

Introduction: Pancreatic neuroendocrine tumours (panNETs) originate from neuroendocrine cells with high rates of metastasis, rendering many patients’ ineligible for surgical resection. The first-line chemotherapeutic agent temozolomide (TMZ) for metastatic panNETs faces challenges related to resistance, primarily mediated by the DNA repair enzyme O6-methylguanine-DNA methyltransferase (MGMT).
