(Submitter supplied) Acinar and ductal cells are the major epithelial cell types in the exocrine pancreas, but which of these serves as the cell-of-origin in human PDAC has been debated. Our mouse models have demonstrated that oncogenic Kras expression and Trp53 loss in pancreatic acinar or ductal cells can lead to pancreatic cancer. Here, we performed gene expression profiling of bulk acinar cell-derived and ductal cell-derived mouse pancreatic tumors to identify the transcriptomic profiles.

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer embedded in an extensive desmoplastic stroma. Since this challenges the molecular analyses of bulk tumor samples, we FACS-purified epithelial cells from PDAC and healthy human pancreas and performed genome-wide transcriptome and DNA methylome analyses. Clustering based on DNA methylation revealed two distinct groups of PDAC with different methylation levels at genomic regions encoding repeat elements. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) is a deadly disease when diagnosed at a late stage, however patient survivorship significantly increases when the disease is detect prior to metastasis. To study the earliest events leading to PDAC initiation, we developed a genetically engineered mouse model of PDAC utilizing a tamoxifen-inducible Cre Recombinase knocked into the transcription factor Ptf1a locus to induce expression of oncogenic KrasG12D and Trp53R270H alleles in adult pancreatic acinar cells. more...

(Submitter supplied) We have previously described in mouse models that pancreas-specific deletion of Gata6 results in pancreas alterations by rendering pancreatic acinar cells in a non-fully differentiation state, and furthermore it accelerates tumor initiation and progression in a pro-tumorigenic context (KrasG12V expression). We aim to determine the sites where Gata6 binds at the genome-wide level in the pancreas to unveil why its loss leads to altered pancreatic function and enhanced tumor formation when coexpressed with KrasG12V.

(Submitter supplied) We report the global gene expression of mouse pancreatic cells in a pancreas-specific conditional knock-out mouse for Gata6, as compared with age-matched controls. Total RNA was extracted from the pancreas of 6-8 -week old mice of the two genotypes and analyzed. at this age, Gata6P-/- pancreata are histologically normal, but the acinar differentiation programme is already altered. we observe that loss of Gata6 causes the de-repression of ectopic non-pancreatic genes, as well as some genes involved in the mesenchymal programme.

(Submitter supplied) By studying a mouse model, as well as human tumors samples and cell lines, we have revealed a tumor suppressive role for Gata6 in the pathogenesis of pancreatic ductal adenocarcinoma (PDAC). In order to understand the mechanism underlying such tumor suppressive function, we analyzed the genome-wide DNA-binding of GATA6 in a human PDAC cell line (PaTu8988S). GATA6 is found to bind the promoter of genes involved in the epithelial differentiation programme, as well as of genes involved in the mesenchymal programme. more...

(Submitter supplied) Pancreatic ductal adenocarcinoma (PDAC) has a poor prognosis and is among the most common causes of cancer death worldwide. KrasG12D mutation is the main driver mutation but insuffi-cient for progression of invasive cancer on its own indicating that other pathways, such as Notch signaling may participate in that process. RBPJ, the only transcription factor in Notch signaling, is frequently lost in human cancers and associated with more aggressive breast cancer phenotype. more...
