Expression profile of GATA6 deficient pancreatic islets

ABSTRACT: GATA6 mutations have been linked to adult-onset diabetes with subclinical or no exocrine insufficiency suggesting an important role for GATA6 in humanβcell physiology. To investigate the role of GATA6 in adult endocrine pancreas, we generated mice in which Gata6 is specifically inactivated in the pancreas. These mice develop glucose intolerance. Islets deficient in GATA6 activity display decreased insulin content and impaired glucose-induced insulin secretion. Gata6-deficient ß cells exhibit ultrastructural abnormalities including increased immature insulin granules, swollen mitochondria and disorganized endoplasmic reticulum. Microarray analysis revealed that loss of GATA6 greatly impacts ß cell specific gene expression.

GATA6-AS1 Regulates GATA6 Expression to Modulate Human Endoderm Differentiation

Project description:Transcriptome analysis has uncovered a series of long noncoding RNAs (lncRNAs) transcribed during cell differentiation. Here, we uncovered lncRNA GATA6-AS1 is a functional lncRNA in definitive endoderm (DE) differentiation. We found GATA6-AS1 positively regulated the expression of endoderm key factor GATA6, which was different from previous reports in other biological contexts. Further investigation showed GATA6-AS1 interacted with SMAD2/3 and recruited SMAD2/3 to the promoter region of the GATA6 gene locus. In addition, overexpression of GATA6 was able to rescue the defect of DE differentiation due to the absence of GATA6-AS1, suggesting GATA6 was the functional target of GATA6-AS1 during endoderm differentiation. Ultimately, our study uncovers GATA6-AS1 is necessary for DE and pancreas differentiation, and reveals the detailed regulation mechanism between GATA6-AS1 and DE differentiation.

Genome-wide map of Gata6 DNA binding in mouse pancreas

Project description: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.

Genome-wide maps of Gata6 in primary mouse keratinocytes

Project description:In adult K14ΔNLef1 mouse, the overexpression of ∆NLef1, a ß-catenin dominat negative, in basal keratinocytes leads to the conversion of hair follicles into multilayered epithelial cysts and ectopic sebaceous gland. ∆NLef1 transcriptional activity led to Gata6 overexpression in the pilosebaceous unit in transgenic mice. To uncover direct target genes of Gata6 we performed ChIP-Seq experiments in primary mouse keratinocytes.

Global gene expression in the adult Gata6 null mouse pancreas

Project description: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. mRNA extracted from the pancreas of 4 controls and 4 Gata6P-/- mice was sequenced.

Pancreas-specific Sirt1-deficiency in mice compromises beta-cell function without development of hyperglycemia

Project description:Sirtuin 1 (Sirt1) has been reported to be a critical positive regulator of glucose-stimulated insulin secretion in pancreatic beta-cells. The effects on islet cells and blood glucose levels when Sirt1 is deleted specifically in the pancreas are still unclear.This study examined islet glucose responsiveness, blood glucose levels, pancreatic islet histology and gene expression in Pdx1-Cre;Sirt1(ex4F/F) mice that have loss of function and loss of expression of Sirt1 specifically in the pancreas. We found that in the Pdx1-Cre;Sirt1(ex4F/F) mice, the relative insulin positive area and the islet size distribution were unchanged. However, beta-cells were functionally impaired, presenting with lower glucose-stimulated insulin secretion. This defect was not due to a reduced expression of insulin but was associated with a decreased expression of the glucose transporter Slc2A2/Glut2 and of the Glucagon like peptide-1 receptor (Glp1r) as well as with a marked down regulation of endoplasmic reticulum (ER) chaperones that participate in the Unfolded Protein Response (UPR) pathway. Counter intuitively, the Sirt1-deficient mice did not develop hyperglycemia. Pancreatic polypeptide (PP) cells were the only other islet cells affected, with reduced numbers in the Sirt1-deficient pancreas. This study provides new mechanistic insights showing that beta-cell function in Sirt1-deficient pancreas is affected due to altered glucose sensing and deregulation of the UPR pathway. Interestingly, we uncover a context in which impaired beta-cell function is not accompanied by increased glycemia. This points to a unique compensatory mechanism. Given the reduction in PP, investigation of its role in the control of blood glucose is warranted. To uncover other Sirt1-regulated mechanisms, we performed a gene expression microarray analysis comparing pancreata from the 6 month old Sirt1âdeficient mice to their controls (n=3 per group).

Pluripotent stem cell disease modeling of GATA6 haploinsufficiency in human pancreatic development

Project description:To better understand molecular mechanisms of human pancreatic development associated with GATA6 haploinsufficiency, we performed RNA-seq analysis to characterize the biological processes affected by GATA6 heterozygous mutation. We found majority of top downregulated transcription factors are known to play key roles in pancreatic development and top downregulated genes were enriched with factors involved in developmental processes, with the pancreas being the top affected lineage.

Genomic profiling identifies GATA6 as a candidate oncogene amplified in pancreatobiliary cancer

Project description:Pancreatobiliary cancers have among the highest mortality rates of any cancer type. Discovering the full spectrum of molecular genetic alterations may suggest new avenues for therapy. To catalogue genomic alterations, we carried out array-based genomic profiling of 31 exocrine pancreatic cancers and 6 distal bile duct cancers, expanded as xenografts to enrich the tumor cell fraction. We identified numerous focal DNA amplifications and deletions, including in 19% of pancreatobiliary cases gain at cytoband 18q11.2, a locus uncommonly amplified in other tumor types. The smallest shared amplification at 18q11.2 included GATA6, a transcriptional regulator previously linked to normal pancreas development. When amplified, GATA6 was overexpressed at both the mRNA and protein level, and strong immunostaining was observed in 25 of 54 (46%) primary pancreatic cancers compared to 0 of 33 normal pancreas specimens surveyed. GATA6 expression in xenografts was associated with specific microarray gene-expression patterns, enriched for GATA binding sites and mitochondrial oxidative phosphorylation activity. siRNA mediated knockdown of GATA6 in pancreatic cancer cell lines with amplification led to reduced cell proliferation, cell cycle progression, and colony formation. Our findings indicate that GATA6 amplification and overexpression contribute to the oncogenic phenotypes of pancreatic cancer cells, and implicate GATA6 as a lineage-specific oncogene in pancreatobiliary cancer, with implications for novel treatment strategies. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Tissue type: cancer xenograft from diff tissues Keywords: Logical Set cDNA microarrays from the Stanford Functional Genomics Facility were used to perform gene expression profiling on 28 out of 31 of the exocrine pancreatic cancer and all 6 distal bile duct cancer xenografts.
