(Submitter supplied) Activting transcription factor 6 (Atf6) is one of three main mediators of the Unfolded Protein Response and it gets cleaved cleaved in the Golgi and its N-terminal consisting of the bZip domain translocates into the nucleus to generate a transcriptional response (nAtf6). This study carries out RNAseq on an established transgenic overexpression of nAtf6 in zebrafish hepatocytes ( tg(fabp10:nAtf6-cherry; cmlc2:GFP)-C allele). more...

(Submitter supplied) Exposure to ethanol causes liver injury and activates stress response pathways. Here we compared gene expression in the zebrafish larval liver between larvae that were untreated and those exposed to 175 mM and 350 mM ethanol from 96-120 hours post fertilization (hpf).

(Submitter supplied) Disruptions of the endoplasmic reticulum (ER) that perturb protein folding cause ER stress and elicit an unfolded protein response (UPR) that involves translational and transcriptional changes in gene expression aimed at expanding the ER processing capacity and alleviating cellular injury. Three ER stress sensors PERK, ATF6, and IRE1 implement the UPR. PERK phosphorylation of eIF2 during ER stress represses protein synthesis, which prevents further influx of ER client proteins, along with preferential translation of ATF4, a transcription activator of the integrated stress response. more...

(Submitter supplied) The unfolded protein response (UPR) maintains endoplasmic reticulum (ER) proteostasis through the activation of transcription factors such as XBP1s and ATF6. The functional consequences of these transcription factors for ER proteostasis remain poorly defined. Here, we describe methodology that enables orthogonal, small molecule-mediated activation of the UPR-associated transcription factors XBP1s and/or ATF6 in the same cell independent of stress. more...

(Submitter supplied) Eukaryotic cells maintain protein homeostasis through the activity of multiple basal and inducible systems, which function in concert to allow cells to adapt to a wide range of environmental conditions. Although the transcriptional programs regulating individual pathways have been studied in detail, it is not known how the different pathways are transcriptionally integrated such that a deficiency in one pathway can be compensated by a change in an auxiliary response. more...

(Submitter supplied) We wished to determine the effects of activating the transcription factor, ATF6, on global miRNA expression. We utilized transgenic mice with a conditionally tamoxien-responsive form of ATF6 and assessed cardiac lysates from NTG and TG mice, both treated with tamoxifen and untreated, in order to identify differentially expressed miRNAs. We then focused on miRNAs of interest as well as the genes they are predicted to regulate.

(Submitter supplied) Very little is known on the nature of epigenetic states in developing zebrafish despite its growing importance as a model organism in developmental biology. We report histone modifications on promoters of pluripotency genes in zebrafish embryos at the mid-late blastula transition (MBT+) stage. We identify three classes of expressed genes based on these profiles: (1) those with a promoter occupied by marks of active genes without any repressive marks; (2) those co-occupied by both activating and repressive modifications; of these genes, klf4 was notably found to be mosaically expressed in the embryo, possibly accounting for this epigenetic pattern; (3) those occupied by repressive marks with, surprisingly, little not acetylated H3K9 or H4. more...

(Submitter supplied) We compared gene and protein expression profiles in cells challenged with ER stress-inducing drugs or expressing model polypeptides. Drugs titration to limit up-regulation of the endogenous ER stress reporters BiP/HSPA5 and HERP/HERPUD1 to levels comparable to luminal accumulation of unfolded proteins substantially reduced the amplitude of transcriptional and translational responses.

(Submitter supplied) We recently found that the endoplasmic reticulum (ER) stress response (ERSR) is activated in surviving cardiac myocytes in a mouse model of in vivo myocardial infarction. ATF6 is an ER stress-activated transcription factor that induces ERSR genes, some of which encode proteins that may protect against ischemic damage. However, few ERSR genes have been identified in the heart, and there have been no gene expression profiling studies of ATF6-inducible genes, in vivo. more...
