Project description:To analyse gene expression differences between the human TFEB overexpressing cells vs. Controls, under growing conditions (GC) vs. Fasting conditions (Fast)
Project description:By using His6-tagged recombinant human secretagogin in the presence of Ca2+ (100 µM), we precipitated putative interacting partners from INS-1E cells and identified their amino acid sequences by mass spectrometry. We detected canonical interacting proteins participating in vesicle-mediated transport, exocytosis and cytoskeletal organization. Besides, we captured proteins controlling protein folding and (de-)ubiquitination. Our data support that secretagogin modulates protein folding and degradation through protein-protein interactions and interacts with USP9X in β cells to control cell survival.
Project description:Cytokine-induced beta-cell apoptosis is a key event for the death of pancreatic beta cells in the development of type-1 diabetes. We identified BRD0476 as a novel suppressor of cytokine-induced beta-cell apoptosis. We used microarrays to look for gene set(s) that are regulated by BRD0476. Rat INS-1E cells were treated with cytokine cocktails (IL-1b, IFN-g and TNF-a) and/or BRD0476 for 6 or 12 hours. Total RNAs were isolated using the RNEasy kit from Qiagen.

Project description:This study aims at elucidating how Coxsackie B virus infection perturbs the host's miRNA regulatory pathways that may lead to different pathological events using the miRNA microarray approach. The rat pancreatic cell line - INS-1E, was infected with various preparations of Coxsackie B4 viruses was analysed for miRNA expression profiles subsequently. The miRNA expression profiles were measured at 48, and 72 hours post infection, respectively.
Project description:Time course treatment with 0.4 mM Palmitate and 200 nM thapsigargin of insulinoma INS-1E cells. Timepoints; 0, 4, 16 and 24h in biological duplicates within an iTRAQ 8 set for palmitate and thapsigargin, respectively.
Project description:Locally released cytokines contribute to beta cell dysfunction and apoptosis in Type 1 diabetes. In vitro exposure of insulin producing INS-1E cells to the cytokines interleukin (IL)-1beta + interferon (IFN) gamma leads to a significant increase in apoptosis. To characterize the genetic networks implicated in beta cell dysfunction and apoptosis and its dependence on nitric oxide (NO) production, we performed a time course analysis using the Affymetrix RG U34A microarry. INS-1E cells were exposed in duplicate to IL-1beta + IFN-gamma for six different time points (1, 2, 4, 8, 12, and 24 h) with or without the inducible NO synthase blocker.
