Development of miRNA expression signatures of MEFs deficient in a ER stress mediator ATF6a for tunicamycin treatment

Project description:To further development of our miRNA expression approach to ER stress, we have employed miRNA microarray expression profiling as a discovery platform to identify ER stress-responsible ones. Mouse embryonic fibroblasts (MEFs) deficient in a ER stress mediator ATF6a were treated with tunicamycin for 12 or 24 hrs. miRNAs responsible for tunicamycin-treatment for 12hrs in ATF6a-dependent manner were extracted. Among them, expression of three miRNAs (miR-26a, miR-27b, miR-143) was quantified in the RNA samples from the same as the microarray by real-time PCR. Mouse embryonic fibroblasts (MEFs) deficient in a ER stress mediator ATF6a were treated with 2ug/mL tunicamycin for 12 or 24 hrs. Two independent experiments were performed at each time (untreated, 12 or 24 hrs). miRNAs responsible for tunicamycin-treatment for 12hrs in ATF6a-dependent manner were extracted.

Development of mRNA and lincRNA expression signatures of MEFs deficient in ER stress mediators for tunicamycin treatment

Project description:To further development of our mRNA or lincRNA expression approach to ER stress, we have employed whole genome microarray expression profiling as a discovery platform to identify ER stress-responsible genes. Mouse embryonic fibroblasts (MEFs) deficient in each ER stress mediator (XBP1, ATF4, ATF6a or ATF6b) were treated with tunicamycin for 12 or 24 hrs. Genes responsible for tunicamycin in each mediator-dependent manner were extracted and categorized by Gene Ontology. Among them, expression of five ER-related genes (Derl1, Ssr3, Magt1, Bet1 and Mcfd2) was quantified in the RNA samples from COS7 cells by real-time PCR, confirming existence of similar mechanisms of trancriptional activation in ER stress by tunicamycin treatment. Mouse embryonic fibroblasts (MEFs) deficient in each ER stress mediator (XBP1, ATF4, ATF6a or ATF6b) were treated with 2ug/mL tunicamycin for 12 or 24 hrs. Two independent experiments were performed for each mediator-deficient MEF at each time (untreated, 12 or 24 hrs). Genes responsible for tunicamycin in each mediator-dependent manner were extracted and categorized by Gene Ontology in GeneRanker program of Genomatix platform.

RNAseq Analysis of TP53+/+ and TP53-/- HCT116 colon carcinoma cell lines after treatment with p53 or ATF4-activating compounds

Project description:We examined the gene expression changes resulting from treatment of either "wild-type" or "p53-deficient" human cell lines with compounds known to activate either p53 (nutlin-3A,etoposide) or the integrated stress response (ISR) transcription factor ATF4 (histidinol,tunicamycin)

Gene expression profile of ATF6a and ATF6b knockout mice with dextran sulfate sodium (DSS)-induced colitis

Project description:To understand the role of ATF6a and ATF6b in non-canonical endoplasmic reticulum stress response pathway, we have employed whole genome microarray expression profiling to identify the genes regulated by ATF6s. WIild type or, ER stress mediators,ATF6a or ATF6b-knockout mice were treated with 3% DSS for 3days. Genes responsible for DSS in each mediator-dependent manner were extracted and categorized by Gene Ontology. Among them, expression of three cell structure-related genes (Muc2, Muc3, Muc4) was quantified in the RNA samples from another mice treated with DSS by real-time PCR. Colitis was induced with 3% DSS, 36,000-50,000 M.W. (MP Biomedicals,) in the drinking water for 3 days. Genes responsible for DSS treatment in each mediator-dependent manner were extracted and categorized by Gene Ontology in GeneRanker program of Genomatix platform.

Transcriptomic analysis of endoplasmic reticulum stress (ERS) regulated genes in the liver of NFIL3 KO mice.

Project description:Livers from wild-type (WT) or NFIL3 knock-out (NFIL3 KO) C57Bl6 mal adult mice treated with the ERS-drug tunicamycin were used to prepare RNA.
