Project description:Analysis of expression profile of peripheral blood from pancreatic ductal adenocarcinoma patients RNA expression profile of peripheral blood from pancreatic ductal adenocarcinoma patients
Project description:Analysis of expression profile of peripheral blood from pancreatic ductal adenocarcinoma patients RNA expression profile of peripheral blood from pancreatic ductal adenocarcinoma patients Total RNA was isolated from peripheral blood. 36 patients with unresectable PDAC were recruited. The diagnosis of PDAC was based on clinical evaluation and imaging studies, which were histologically confirmed by surgery or imaging-guided biopsy. 14 gender, age, and habits matched healthy controls were also included. A total of 1000 ng of total RNA was processed using Illumina TotalPrep RNA Amplification Kit. Hybridization of human samples was performed on Illumina Human-HT12 Version 4.
Project description:Pancreatic ductal adenocarcinoma (PDAC) cells undergo epithelial mesenchymal transdifferentiation (EMT) in adaption to environmental cues, including inflammation, a process that combines tumour cell dedifferentiation with dissemination and acquisition of stemness features. However, the mechanisms coupling inflammation-induced signalling pathways with EMT and stemness remain largely unknown. Here, we reveal the inflammation-induced transcription factor NFATc1 as a central regulator of pancreatic cancer cell plasticity.
Project description:Pancreatic acinar cells can dedifferentiate upon tissue injury and acquire ductal characteristics. This acquisition of duct cell features is critical in tumor development. Nevertheless, duct cells themselves are less prone for development of PDAC (pancreatic ductal adenocarcinoma) than dedifferentiated acini. We aimed to clarify which genes are unique for dedifferentiated acini. Mixed exocrine preparations of acinar and duct cells were obtained from human pancreatic donor organs and cultured to induce dedifferentiation. We lineage-labeled and FACS-purified these human dedifferentiated acinar cells and compared them to duct cells from the same donor (n=5).
Project description:Flow-sorted pancreatic acinar and ductal cells from fresh human pancreatic exocrine tissue were subjected to molecular characterization to identify lineage-specific expression and epigenetic properties. Cells of both lineages were cultured and transformed via lentiviral mutation to form pancreatic ductal adenocarcinoma.

Project description:The major objective of this study was to characterise theHapT1 orthotopic hamster pancreatic tumor as a preclinical model of desmoplastic pancreatic ductal adenocarcinoma; and use this model to validate the efficacy of drugs that kills activated pancreatic stellate cells (PSCs)in vitro. Experimentaldesign: Commercially procured HapT1 pancreatic cancer (PCA) cell line was implanted in the pancreas of its syngeneic host, Syrian golden hamster (Mesocricetusauratus). After certain time period the primary and secondary tumors were harvested for histological andimmunophynotypical analysis. PSCs of hamsters were harvested, cultured and characterised. The in-cultured activated rodent PSCs and commercially procured human PSCs were used to check the cytotoxic effect of Disulfiram (DSF) in presence and absence of copper (Cu )in vitro. Finally, theHapT1 orthotopic tumor model was used to check the efficacy of DSF in vivo.
