(Submitter supplied) Objective: Homozygous loss-of-function mutations in the gene coding for the homeobox transcription factor (TF) PDX1 leads to pancreatic agenesis, whereas heterozygous mutations can cause Maturity-Onset Diabetes of the Young 4 (MODY4). Although the function of Pdx1 is well studied in pre-clinical models during insulin-producing β-cell development and homeostasis, it remains elusive how this TF controls human pancreas development by regulating a downstream transcriptional program. more...

(Submitter supplied) Missense mutations in coding region of PDX1 predispose to type-2 diabetes mellitus as well as cause MODY through largely unexplored mechanisms. Here, we screened a large cohort of subjects with increased risk for diabetes and identified two subjects with impaired glucose tolerance carrying heterozygous missense mutations in the PDX1 coding region leading to single amino acid exchanges (P33T, C18R) in its transactivation domain. more...

(Submitter supplied) Despite this critical role in islet cell development, the precise function and downstream genetic programs regulated directedly by NEUROG3 remain elusive. We therefore mapped genome-wide NEUROG3 occupancy in human induced pluripotent stem cell (iPSC)-derived endocrine progenitors and determined NEUROG3 dependency of associated genes to uncover direct targets. To this aim, we generated a novel hiPSC line (NEUROG3-HA-P2A-Venus), where NEUROG3 is HA-tagged and fused to a self-cleaving fluorescent VENUS reporter. more...

(Submitter supplied) Heterozygous mutations in HNF1B in humans result in a multi-system disorder, including pancreatic hypoplasia and diabetes mellitus. The underlying mechanisms that contribute to disease pathogenesis remain largely unknown, partially accounted by the fact that mouse models with heterozygous deletions in Hnf1b do not develop diabetes, in contrast to the phenotypes observed in MODY patients. Here we used a well-controlled human induced pluripotent stem cell pancreatic differentiation model to elucidate the molecular mechanisms underlying HNF1B-associated diabetes and pancreatic hypoplasia. more...

(Submitter supplied) Pancreatic beta cell generation from induced pluripotent stem cells (iPSCs) offers an alternative donor tissue source; however, the efficiency of induction of INSULIN (INS)+ cells from human iPSCs (hiPSCs) is low. We aimed to establish an efficient differentiation protocol for generating INS+ cells from hiPSCs by identifying novel inducers. We screened small molecules that increased the induction rate of INS+ cells from hiPSC-derived PDX1+ pancreatic progenitor cells by using high-throughput screening (HTS) system. more...

(Submitter supplied) We have studied the impact of T2D on open chromatin in human pancreatic islets. We used assay for transposase-accessible chromatin using sequencing (ATAC-seq) to profile open chromatin in islets from T2D and non-diabetic donors. We identified ATAC-seq peaks representing open chromatin regions in islets of non-diabetic and diabetic donors. The majority of ATAC-seq peaks mapped near transcription start sites. more...
