(Submitter supplied) In this project we have used single cell RNA-seq to profile pancreatic cancer development in a mouse model, from pre-invasive stage to cancer, and in human PDAC sample. Using a reporter gene, we were able to dissect metaplastic acinar cell heterogeneity, profiled six different acinar metaplastic cell types and states, validated their localization to pre-invasive lesions and correlated findings with human PDAC. more...

(Submitter supplied) Cellular senescence is a central barrier to tumorigenesis, acting to block the proliferation of premalignant cells. However, senescent cells residing within tumor lesions can also exert paracrine effects influencing tumor growth and progression. Premalignant pancreatic intraepithelial neoplasia (PanIN) lesions contain senescent cells, yet whether these influence disease progression is unknown. Here we report that senescent cells in PanINs that develop in a Kras-driven mouse model express a pro-inflammatory gene signature, which includes high Cox2 levels. 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) Oncogenic mutations in Kras initiate neoplastic transformation in the pancreas through a process that hijacks the activity of developmental regulators and induces an inflammatory microenvironment. We report that the homeodomain transcription factor Prox1 is a novel component of a progenitor signature that is activated in acinar cells undergoing dedifferentiation and ductal metaplasia conversion. Also, the conditional deletion of a single Prox1 allele markedly accelerates early transformation and significantly enhances features of inflammation in pancreatic tissues carrying a Kras oncogene. more...

(Submitter supplied) Accumulation of genetic mutations is thought to be a primary cause of cancer. However, a set of genetic mutations sufficient for cancer development remains unclear in most cancers, including pancreatic cancer. Here, we examined the effect of in vivo reprogramming on Kras-induced cancer development. We first demonstrate that Kras and p53 mutations are insufficient to induce activation of ERK signaling and cancer development in the pancreas. more...

(Submitter supplied) BACKGROUND & AIMS: Acinar cells produce digestive enzymes that impede transcriptomic characterization of the exocrine pancreas. Thus, single-cell RNA-sequencing (scRNA-seq) studies of the pancreas underrepresent acinar cells relative to histological expectations, and a robust approach to capture pancreatic cell responses in disease states is needed. We sought to innovate a method that overcomes these challenges to accelerate study of the pancreas in health and disease. more...

(Submitter supplied) In this study, we performed laser capture microdissection (LCM) of PDAC samples to define their cancer- and stroma-specific molecular subtypes and identify a prognostic gene expression signature for short-term and long-term survival. LCM and RNA-seq analysis of cancer and adjacent stroma of 19 treatment-naïve PDAC tumors were performed. Gene expression signatures were tested for their robustness in a large independent validation set. more...

(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.
