Transcription profiling of pancreatic islets from heterozygous Hnf1a-mutant and wild type mice

ABSTRACT: Pancreatic islets were isolated from Hnf1a+/- (Hepatocyte nuclear factor 1 alpha) and wild-type mice and cultured ex vivo for two days in RPMI medium with 10% FBS before RNA extraction. The transcription profiles were obtained using Affymetrix GeneChip Mouse Genome 430 2.0 arrays [Mouse430_2].

Heterozygous HNF1A mutations cause pancreatic-islet beta-cell dysfunction and monogenic diabetes (MODY3). Hnf1alpha is known to regulate numerous hepatic genes, yet knowledge of its function in pancreatic islets is more limited. We now show that Hnf1a deficiency in mice leads to highly tissue-specific changes in the expression of genes involved in key functions of both islets and liver. To gain insights into the mechanisms of tissue-specific Hnf1alpha regulation, we integrated expression studies ...[more]

Transcription profiling of pancreatic islets from wild type, pancreas-specific Hnf4alpha knockout, heterozygous Hnf1alpha, and double mutant mice

Project description:Gene expression differences between wild-type, pancreas-specific Hnf4alpha knockout (Hnf4a-pKO), heterozygous Hnf1alpha (Tcf1) (Hnf1aHET), and double mutant (Hnf4a-pKO;Hnf1aHET) mouse pancreatic islets were assesed using amplified RNA samples from islets of matched quality and endocrine purity, obtained from 60-75 day-old control and genetically modified male mice after 48 hours in culture. RNA was amplified using the Affymetrix GeneChIP two-cycle protocol and hybridized to Affymetrix GeneChip Mouse Genome 430 2.0 arrays [Mouse430_2].

Human Pancreatic Islets Expressing HNF1A Variant Have Defective β cell Transcriptional Regulatory Networks

Project description:Using an integrated approach to characterize the pancreatic tissue and isolated islets from a 33-year-old with 17 years of type 1 diabetes (T1D), we found donor islets contained β cells without insulitis and lacked glucose-stimulated insulin secretion despite a normal insulin response to cAMP-evoked stimulation. With these unexpected findings for T1D, we sequenced the donor DNA and found a pathogenic heterozygous variant in hepatocyte nuclear factor 1 alpha (HNF1A). In one of the first studies of human pancreatic islets with a disease-causing HNF1A variant associated with the most common form of monogenic diabetes, we found that HNF1A dysfunction leads to insulin-insufficient diabetes reminiscent of T1D by impacting the regulatory processes critical for glucose-stimulated insulin secretion and suggest a rationale for a therapeutic alternative to current treatment.

HNF1A, UTX, H3K27me3 and H3K27ac ChIP-seq in wild-type and UTX- or HNF1A-deficient mouse pancreas

Project description:HNF1A and UTX are putative tumor suppressors in pancreatic cancer. In this study, we have combined mouse genetics, transcriptomics and genome binding studies to link HNF1A and UTX in a molecular mechanism that suppresses pancreatic cancer. In this session, we have profiled UTX, HNF1A, H3K27me3 and H3K27ac in normal and UTX- or HNF1A-deficient mouse pancreas by ChIP-seq experiments. We show that HNF1A recruits UTX to its genomic targets in pancreatic acinar cells, which results in remodeling of the chromatin landscape and activation of a broad transcriptional program of differentiated acinar cells, which in turn indirectly suppresses tumor suppressor pathways.

UMI-4C in control and HASTER-deficient EndoC-betaH3 cells overexpressing HNF1A

Project description:The HASTER promoter region is a cis-regulatory element that stabilizes the transcription HNF1A. If HASTER is deleted after beta cells have been formed and HNF1A is already stably expressed, HASTER is not required to maintain HNF1A activity, and is only required to provide negative feedback on HNF1A. HNF1A binding to the HASTER promoter mediates the repression of the HNF1A gene itself. To determine whether HNF1A binding to the HASTER promoter remodels 3D chromatin interactions of the HNF1A promoter, we performed UMI-4C experiments in wild type and HASTER-promoter KO EndoC-betaH3 cells with or without doxycycline-induced HNF1A overexpression using the HNF1A promoter as viewpoint.

HNF1A deficiency impairs β-cell fate, granule maturation and function

Project description:Mutations in HNF1A cause Maturity Onset Diabetes of the Young type 3, the second most frequent form of diabetes caused by single gene mutation. We generated human pancreatic stem cell-derived endocrine cells with mutations in HNF1A and show that HNF1A deficiency impairs scβ-cell fate, insulin granule maturation and the secretion of insulin in a glucose responsive manner. Single-cell RNA sequencing reveals that HNF1A orchestrates a network of genes involved in glucose metabolism, zinc transport, calcium ion binding and hormone exocytosis. Furthermore, in both patients and stem cell-derived β-cells, HNF1A deficiency altered the stoichiometry of secreted c-peptide to insulin. Sulfonylurea, used in the treatment of these patients, restored both insulin secretion and stoichiometry. Significantly, uncoupling of c-peptide and insulin secretion as described here questions the common practice in using c-peptide as a proxy to evaluate β-cell function. We also demonstrate that correction of the HNF1A locus restores function, providing a path to cell therapy.
