(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) 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) 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) 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) 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) Purpose: The goal of the study was to determine the effects of forced expression of the acinar transcription factors MIST1 and PTF1a in PDAC cells. Methods: Doxycycline inducible MIST1myc and PTF1amyc Panc-1 cells were generated using Clontech's Tetone System and subjected to RNA-Sequencing following doxycycline treatment. Results: 50 million sequence reads were mapped to the human genome. Data suggests acinar associated molecules were induced upon doxycyline treatment. more...

Design We generated transgenic mouse models in which mTOR was hyperactivated either through the Kras/Mek/Erk cascade, by loss of Pten or through Tsc1 haploinsufficiency. more...

(Submitter supplied) Analysis of induced E47 expression on PDA cells at the gene expression level.The hypothesis tested in the present study was that PDA cells can be reprogrammed to revert to their original quiescent acinar cell phenotype by stimulating a tamoxifen inducible form of E47 fused to a modified estrogen (E47-ER) receptor . Results provide important information on the remarkable ability of E47ER to trigger reactivation of the acinar cell differentiation program and cell cycle arrest in PDA cells.

(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...
