A series of C10-position imidazole-modified catalpol derivatives are specifically designed and synthesized for serving as potential pancreatic cancer inhibitors, which are characterized by H NMR, C NMR and high-resolution mass spectrometry (HRMS). They were evaluated by the 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) test on two human pancreatic cancer cells PANC-1, BxPC-3 and normal pancreatic cell HPDE6-C7, which showed the significant inhibitory effected on the growth of human pancreatic cancer cells of PANC-1 and BxPC-3, especially 91.6% efficacy on BxPC-3, and 73.1% on PANC-1. Simulation studies like molecular docking supported strong binding of vascular endothelial growth factor receptor 2 (VEGFR-2) protein tyrosine kinase (PDB ID: 4AGD), a target of pancreatic cancer. A novel imidazol-modified catalpol compound 3i with strong inhibitory effect on pancreatic cancer cells, which could potentially develop into anti-pancreatic cancer drug candidates in the future.

Pancreatic cancer is a lethal disease with an insidious onset, and little is known about its early molecular events. Here, we found that the sterol regulatory element-binding protein 1 (SREBP1) expression is gradually upregulated during the initiation of pancreatic cancer. Through in vitro 3D culture of pancreatic acinar cells and experiments in LSL-Kras;Pdx1-Cre (KC) mice, we found that pharmacological inhibition of SREBP1 suppressed pancreatic tumorigenesis.

Lipid metabolism in cancer is characterized by dysregulated lipid regulation and utilization, critical for promoting tumor growth, survival, and resistance to therapy. Pancreatic cancer (PC) is a highly aggressive malignancy of the gastrointestinal tract that has a dismal 5-year survival rate of less than 10%. Given the essential function of the pancreas in digestion, cancer progression severely disrupts its function.

Background: Despite advances in treatment, the incidence of postoperative complications following pancreatectomy remains high, leading to frequent hospital readmissions. Therefore, this study aimed to investigate the relationship between preoperative exercise tolerance and the likelihood of unplanned readmission in patients with pancreatic ductal adenocarcinoma.
Methods: This retrospective analysis included 88 patients who underwent pancreatectomy at a single institution between July 2019 and September 2022 and focused on patients with pancreatic ductal adenocarcinoma.

The single nucleotide polymorphism in NOD2 (rs2066847) is associated with conditions that may predispose to the development of gastrointestinal disorders, as well as the known BRCA1 and BRCA2 variants classified as risk factors in many cancers. In our study, we analyzed these variants in a group of patients with pancreatitis and pancreatic cancer to clarify their role in pancreatic disease development. The DNA was isolated from whole blood samples of 553 patients with pancreatitis, 83 patients with pancreatic cancer, 44 cases of other pancreatic diseases, and 116 healthy volunteers.

A 78-year-old male patient came to our hospital with a chief complaint of fever. Computed tomography revealed an indistinct tumor in the pancreatic head, along with dilatation of the bile duct and main pancreatic duct. An endoscopic transpapillary biopsy demonstrated adenocarcinoma in the glandular epithelium and a dense formation of quasi-round cells.
