Project description:We observed that upon the activation of the oncogene KRasG12D and the deletion of the tumour suppressor Fbw7 in pancreatic ducts (KFCkY model), not all ducts respond in the same way. Some ductal cells remain morphologically normal while others exhibit signs of transformation (cellular and nuclear enlargement) with the concomitant upregulation of CD44. Here we wanted to understand the differences between the normal-looking and transformed cells at the transcriptional level.

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: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:Aberrant acinar to ductal metaplasia (ADM), one of the earliest events involved in exocrine pancreatic cancer development, is typically studied using pancreata from transgenic mouse models. We used primary, human pancreatic acinar cells to evaluate the transcriptional profile during the course of ADM.
