Analysis of pancreas from C57BL/6 adults with Mist1-null phenotype rescued by tamoxifen-induced Mist1 expression. Embryonic knockout of Mist1 leads to acinar cell dysfunction, disrupting pancreatic function. Results provide insight into the role of Mist1 in regulating mature acinar properties.

(Submitter supplied) Although early developmental processes involve cell fate decisions that define the body axes and establish progenitor cell pools, development does not cease once cells are specified. Instead, most cells undergo specific maturation events where changes in the cell transcriptome ensure that the proper gene products are expressed to carry out unique physiological functions. Pancreatic acinar cells mature post-natally to handle an extensive protein synthetic load, establsih organized apical-basal polarity for zymogen granule trafficking, and assemble gap-junctions to perimt efficient cell-cell communication. more...

(Submitter supplied) Mouse pancreas from wild type and MistKO animals were induced either with caerulein or saline as control and processed for RNA. Targets from three biological replicates of each were generated and the expression profiles were determined using Affymetrix Mouse Expression chips 430. Comparisons between the sample groups allow the identification of genes with differential expression patterns of genes which might contribute to pancreatitis. more...

Analysis of pancreas from transcription factor Mist1 knockouts (Mist1KO) injected with caerulein. Mist1KOs exhibit disrupted cell morphology in adult pancreatic acini; caerulein induces acute pancreatitis. Results identify genes that may contribute to susceptibility and initiation of pancreatitis.

(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...

(Submitter supplied) Epigenetic profile of tissues is reprogrammed under diseased conditions. H3K4Me3 and H3K27Me3 represent active and repressive epigenetic marks, respectively. ChIP-seq is an effective tool to study global protein-DNA interactions. To study global epigenetic differences, we used H3K4Me3 antibody to evaluate its enrichment in pancreatic acinar cells of WT and Mist1-/- mice followed by next generation sequencing. more...

(Submitter supplied) The transcription factor MIST1 is required for final maturation of secretory cells of diverse tissues, including gastric digestive-enzyme secreting zymogenic (chief) cells (ZCs). Here, we show that MIST1 directly activates RAB26, RAB3D and several other genes.

(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) beta-catenin is an essential mediator of canonical Wnt signaling and a central component of the cadherin-catenin epithelial adhesion complex. Dysregulation of beta-catenin expression has been described in pancreatic neoplasia. Newly published studies have suggested that beta-catenin is critical for normal pancreatic development although these reports reached somewhat different conclusions. In addition, the molecular mechanisms by which loss of beta-catenin affects pancreas development are not well understood. more...

(Submitter supplied) To identify the molecular mechanism of Mist1 during hepatoblasts differentiation, we performed gene expression analysis in Mist1 over-expressed cells. Dlk+ hepatoblasts derived from E13 fetal livers were purified. Purification of Dlk+ cells were performed using anti-Dlk antibody after hematopoietic cells were removed. Cells were infected with mock or Mist1-overexpressing retroviruses and cultured for 3days with oncostatin M.

(Submitter supplied) Antibody secretion by plasma cells provides acute and long-term protection against pathogens. The high secretion potential of plasma cells depends on the unfolded protein response, which is controlled by the transcription factor Xbp1. Here, we analyzed the Xbp1-dependent gene expression program of plasma cells and identified Bhlha15 (Mist1) as the most strongly activated Xbp1 target gene. As Mist1 plays an important role in other secretory cell types, we analyzed in detail the phenotype of Mist1-deficient plasma cells in Cd23-Cre Bhlha15(fl/fl) mice under steady-state condition or upon NP-KLH immunization. more...
