Expression data by BRD7552 treatment in PANC-1 cells

ABSTRACT: Three master regulatory transcription factors Pdx1, MafA and Ngn3 have the ability to transdifferentiate pancreatic acinar cells to insulin-producing beta cells in mice. BRD7552 was identified as a small-molecule inducer that can upregulate the expression of Pdx1 in PANC-1 cells by high-throughput qPCR screening. We used microarrays to illustrate the mechnism of BRD7552 for PDX1 and insulin induction. PANC-1 cells were treated with BRD7552 at 5uM, the mininal concentration for the maximal induction of Pdx1. The RNA was isloated at two time points 6-hour and 72-hour.

Pancreatic and duodenal homeobox 1 (PDX1), a member of the homeodomain-containing transcription factor family, is a key transcription factor important for both pancreas development and mature β cell function. The ectopic overexpression of Pdx1, Neurog3, and MafA in mice reprograms acinar cells to insulin-producing cells. We developed a quantitative PCR-based gene expression assay to screen more than 60,000 compounds for expression of each of these genes in the human PANC-1 ductal carcinoma cell ...[more]

Role of Neurogenin3 phosphorylation in the reprogramming of pancreatic organoids into endocrine cells

Project description:During pancreatic development, Neurogenin3 (Ngn3) promotes the differentiation of endocrine cells, including insulin-producing β-cells. Our previous work has shown that Ngn3 phosphorylation on multiple serine-proline (SP) sites increases protein stability and endocrine differentiation (Azzarelli et al., DevCell 2017). Here, we aim to exploit our recent data to investigate whether manipulation of Ngn3 phosphostatus might improve in vitro generation of β-cells for replacement therapies in diabetes. A potential source of β-cells comes from fate conversion of exocrine pancreatic cells into the endocrine lineage, by overexpression of 3 transcription factors, Ngn3, Pdx1 and MafA. Using this approach we show that pancreatic ductal cells grown in vitro as 3D organoids can be reprogrammed to express insulin. The efficiency can be strongly enhanced by substituting wild type Ngn3 with a the un(der)phosphorylated and more active Ngn3 form (6S-A Ngn3). Here we perform transcriptomic analysis of a low number of pancreatic organoid cells expressing wild type or phosphomutant Ngn3, alone or in various combination Pdx1 and/or MafA. The analysis revealed endocrine differentiation and in particular β-like cell gene expression in the conditions where Ngn3 was in combination with both Pdx1 and MafA.

Transcriptional program for induced delta cell on day10

Project description:Direct lineage conversion of adult cells is a promising approach for regenerative medicine. A major challenge of lineage conversion is to generate specific subtypes of cells, closely related cells with distinct properties. The pancreatic islets contain three major hormone-secreting endocrine subtypes: insulin+ β-cells, glucagon+ α-cells, and somatostatin+ δ-cells. We previously reported that a combination of three transcription factors, Ngn3, Mafa, and Pdx1, directly reprogram pancreatic acinar cells to β-cells. We now show that acinar cells can be converted to δ-like and α-like cells by Ngn3 and Ngn3+Mafa respectively. Thus, three major islet endocrine subtypes can be derived by acinar reprogramming. Ngn3 promotes establishment of a generic endocrine state in acinar cells at the onset of reprogramming in addition to promoting δ-specification. Mafa and Pdx1 suppress δ-specification in α- and β-cell formation. These studies identify a set of defined factors whose combinatorial actions reprogram acinar cells to distinct islet endocrine subtypes in vivo. induced beta cells samples at day 10 collected for the microarray

Long-term correction of diabetes in mice by in vivo reprogramming of pancreatic ducts

Project description:Here, we report in vivo reprogramming of pancreatic ductal cells through intra-ductal delivery of an adenoviral vector expressing the transcription factors Pdx1, Neurog3 and Mafa (adPNM). To better understand the extent of reprogramming in induced pancreatic ductal cells, comparative single cell RNA sequencing was performed on insulin+ pancreatic ductal cells and pancreatic β-cells. Compared with pancreatic β cells, we show that insulin+ pancreatic ductal cells had established a β-cell gene expression program, albeit with immature features.
