Transcriptome analysis of the D3 mouse embryonic stem cell line in comparison to the MIN6 pancreatic beta-cell insulinoma cell line

ABSTRACT: Analysis of the transcriptional differences between mouse ES cells from the D3 cell line and transformed beta-cells (MIN6 cell line) as determined by a direct comparative analysis of their transcriptome. The results show that 40% of transcripts were differentially expressed between D3 and MIN6 cells. There is thus a marked difference in the pattern of transcription between the ES cell and beta-cell genomes.

Transcriptome analysis of the D3 mouse embryonic stem cell line in comparison to the MIN6 pancreatic beta-cell insulinoma cell line

Project description:Analysis of the transcriptional differences between mouse ES cells from the D3 cell line and transformed beta-cells (MIN6 cell line) as determined by a direct comparative analysis of their transcriptome. The results show that 40% of transcripts were differentially expressed between D3 and MIN6 cells. There is thus a marked difference in the pattern of transcription between the ES cell and beta-cell genomes. Total RNA was extracted from three independent replicates of passage 21 D3 cells and passage 23 MIN6 cells. A whole mouse genome comparison between D3 and MIN6 cells was performed using the Mouse WG-6 v2.0 Expression Beadchip from Illumina.

Selenomethionine Modulates Insulin Secretion in the MIN6-K8 Mouse Insulinoma Cell Line

Project description:Selenium is an essential trace element that has gained interest for its potential role in glucose homeostasis. The purpose of the present study was to investigate the impact of selenium supplementation as selenomethionine (SeMet) on insulin secretion in MIN6-K8 cells, a model of pancreatic -cells. We found that 40 μM and 80 μM SeMet significantly enhanced percent insulin secretion at low (2.8 mM), intermediate (11.7 mM), and high (16.7 mM) glucose stimulation. SeMet also increased tolbutamide- or KCl-induced percent insulin secretion at 40 μM and 80 μM. Ca2+ influx was only reduced with 80 μM SeMet. RNA-sequencing showed that 40 μM SeMet supplementation upregulated expression of selenoprotein H (SelH) and thioredoxin reductase 1 (Txnrd 1) and downregulated expression of glutathione peroxidase 3 (Gpx3), selenoprotein O (SelO), and selenoprotein P (SelP). Gpx3 knockdown increased both percent and total insulin release with high glucose stimulation. SelP knockdown increased insulin release at high glucose. In conclusion, high SeMet supplementation augments insulin secretion, while reductions in Gpx3 and SelP expression, from SeMet supplementation or via silencing, augment -cell function in the MIN6-K8 cell line. These studies support a putative role for selenium and selenoproteins in the regulation of glucose homeostasis and diabetes risk.

Selenomethionine modulates insulin secretion in the MIN6-K8 mouse insulinoma cell line.

Project description:Selenium is an essential trace element of interest for its potential role in glucose homeostasis. The present study investigated the impact of selenium supplementation as selenomethionine (SeMet) on insulin secretion in MIN6-K8 cells, a pancreatic β-cell model. We found that SeMet enhanced percent glucose-induced insulin secretion, while also increasing tolbutamide- and KCl-induced percent insulin secretion. RNA-sequencing showed that SeMet supplementation altered expression of several selenoproteins, including glutathione peroxidase 3 (Gpx3) and selenoprotein P (SelP). Targeted knockdown of Gpx3 increased both percent and total insulin release, while SelP knockdown increased insulin content and insulin release. Collectively, these studies support a putative role for selenium and selenoproteins in the regulation of insulin secretion, glucose homeostasis, and diabetes risk.

Metabolomic identification of biochemical changes induced by fluoxetine in an insulinoma cell line (MIN6).

Project description:Background and purposeThe use of fluoxetine raises the risk of pancreatic beta-cell dysfunction. However, the specific mechanism behind its mechanism of action in beta cells is unknown. This study investigated the cellular response of MIN6 cells to fluoxetine using untargeted cell-based metabolomics.Experimental approachMetabolic profiling of MIN6 cells was performed using liquid chromatography-high resolution mass spectrometry (LC-HRMS) analysis on samples prepared under optimized conditions, followed by principal component analysis, partial least squares-discriminant analysis, and pair-wise orthogonal projections to latent structures discriminant analyses.Findings/resultsSixty-six metabolites that had been differentially expressed between the control and fluoxetine-treated groups demonstrated that the citric acid cycle is mainly perturbed by fluoxetine treatment.Conclusion and implicationsThe current study provides insights into the molecular mechanisms of fluoxetine effects in MIN6 cells.

Transcription profiling by array of mouse pancreatic beta cells of MIN6 insulinoma cell line transfected with siRNA directed against murine Meis3 or non targeting control.

Project description:In order to identify genes that are regulated by Meis3, MIN6 insulinoma cells were transfected with siRNA directed against murine Meis3 (siMeis3) or non targeting control (siControl). RNA was harvested and reverse transcribed. Reduced expression of Meis3 was confirmed. The RNA was then submitted for labeling and hybridization to the Agilent cDNA microarray.
