(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) 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) 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) 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...

(Submitter supplied) Inflammation is a major risk factor for pancreatic ductal adenocarcinoma (PDAC). When occurring in the context of pancreatitis, mutations of KRAS accelerate tumor development. We discovered that long after its complete resolution, a transient inflammatory event primes pancreatic epithelial cells to subsequent transformation by oncogenic KRAS. Upon recovery from acute inflammation, epithelial cells of the pancreas display an enduring adaptive response associated with sustained transcriptional and epigenetic reprogramming. more...
