Project description:To identify the target genes of integrated stress reponse (ISR) in adipose tissue, we have employed whole genome microarray expression in adipose specific Fv2E-PERK transgenic mice.
Project description:To identify the target genes of integrated stress reponse (ISR), we have employed whole genome microarray expression in MEF cells. ISR gene setimation under ER stress condition using Perk -/-, Atf4 -/-, eIF2a S51A mutant, Fv2E-PERK MEF cells
Project description:To identify the target genes of integrated stress reponse (ISR) in WAT and BAT, we have employed whole genome microarray expression in WAT and BAT specific Fv2E-PERK transgenic mice. The mAP::Fv2E-PERK transgenic mice were injected by AP20187 or mock.
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.

Project description:In response to different cellular stressors, the ISR kinases, PERK, PKR, HRI and GCN2, activate downstream transcriptional programs. While the core ISR transcription program is well characterized, markers that are specific to each individual ISR kinase activation pathway are not known. To identify markers that are induced by PERK or GCN2, but not the other ISR kinases, we subjected WT, GCN2-/-, and PERK-/- MEFs to amino acid starvation (RPMI 1640 SILAC -Lys -Arg) or Thapsigargin (200nM) treatment for 6 hours to activate the GCN2 and PERK pathways, respectively and performed RNA sequencing.
Project description:Comparison of genes induced during activation of the Integrated Stress Response by tunicamycin or following AP20187 induced dimerization of a Fv2E-PERK chimera in wildtype cells and cells carrying mutations in key ISR signaling molecules.
