Saturated fatty acids induced genes and ISR target genes in pancreatic beta cells

ABSTRACT: To identify the genes induced by lipotoxicity and integrated stress response in pancreatic beta cells, we have employed whole genome microarray expression in panvreatic beta cell line MIN6m9 cells. First microarray analysis : Wild type MIN6m9 cells were treated with Palmitate, Oleate or negative control condition. Second microarray analysis : Wild type and Fv2E-PERK transgened MIN6m9 cells were treated with mock or artificial dimerizer AP20187(AP) in various time course.

ISR target genes in muscle of hSA::Fv2E-PERK

Project description:To identify the target genes of integrated stress reponse (ISR) in skeletal muscle, we have employed whole genome microarray expression in muscle specific Fv2E-PERK transgenic mice and C2C12 myotubes expressed in Fv2E-PERK. As a result, we identified that Fgf21 mRNA expression was commonly induced in skeletal muscle and C2C12.

ISR target genes in the liver of either LFD and HFD-treated Alb::GC mice and AP20187-treated TTR::Fv2E-PERK mice

Project description:The molecular mechanisms linking the stress of unfolded proteins in the endoplasmic reticulum (ER stress) to glucose intolerance in obese animals are poorly understood. In this study enforced expression of a translation initiation 2alpha (eIF2a)-specific phosphatase, GADD34, was used to selectively compromise signaling in the eIF2(Î±P)-dependent arm of the ER unfolded protein response in liver of transgenic mice. The transgene resulted in lower liver glycogen levels and susceptibility to fasting hypoglycemia in lean mice and glucose tolerance and diminished hepato-steatosis in animals fed a high fat diet. Attenuated eIF2(aP) correlated with lower expression of the adipogenic nuclear receptor PPARgamma and its upstream regulators, the transcription factors C/EBPalpha and C/EBPbeta, in transgenic mouse liver, whereas eIF2alpha phosphorylation promoted C/EBP translation in cultured cells and primary hepatocytes. These observations suggest that eIF2(aP)-mediated translation of key hepatic transcriptional regulators of intermediary metabolism contributes to the detrimental consequences of nutrient excess. Keywords: genotype comparison The high expressing Ttr::Fv2E-Perk transgenic mice was injected by either mock or AP20187. Wildtype and Alb::GC transgenic mice were fed by either Low Fat Diet (LFD) or High Fat Diet (HFD) . bred into the Atf4 knockout strain and the derivative compound heterozygous mice (in the mixed FvB/n; Swiss Webster background) were backcrossed to the Atf4+/- parental stock and Ttr::Fv2E-PERK positive siblings with Atf4+/+ and Atf4-/- genetypes were analyzed.

Gene expression profiling of tumor-adjacent histologically normal lung tissues from lung SCC patients

Project description:Tumor-adjacent noncancerous tissues often exhibited abnormalities on molecular levels, which is described as field effect of cancerization. Accumulated evidence demonstrated that filed effect may also play important role in cancer progression. In the present study, we found that the gene expression profile in noncancerous lung tissues adjacent to lung squamous cell carcinoma (SCC) was significantly associated with regional lymph node status of patients. Significance Analysis of Microarrays (SAM) showed that 121 genes were significantly associated with lymph node metastasis (delta=0.75, FDR=0.069). Interestingly, all of the significant genes were up-regulated in the lymph node positive samples. For these genes, the most significant biological GO terms were extracellular structure organization, cell adhesion, regulation of cell motion/migration, and vessel development, etc, which were also involved in EMT process supported by another experiment in vitro. Tumor-adjacent histologically normal lung tissues were collected from 60 primary lung SCC patients, of whom 34 (56.7%) suffered regional lymph node metastasis. Gene expression profiling analysis of these samples was performed using Agilent 4x44K human whole genome gene expression microarray (G4112F).
