Copper sulfate stress effect on kgb-1 mutants

Analysis of kgb-1 mutants incubated with 1mM copper sulfate for 1hr. The conserved KGB-1 JNK mitogen-activated protein kinase pathway regulates the response to heavy metal stress. Results provide insight into molecular mechanisms underlying the heavy metal stress response.

Expression data from C. elegans in the presence or absence of copper sulfate

(Submitter supplied) MAP kinases are integral to the mechanisms by which cells respond to a wide variety of environmental stresses. In Caenorhabditis elegans, the KGB-1 JNK signaling pathway regulates the response to heavy metal stress. The deletion mutants of this cascade show hypersensitivity to heavy metals like copper or cadmium. However, factors that function downstream of KGB-1 pathway are not well characterized. To understand how the KGB-1 pathway modulates gene activity and to define the physiological processes in which the heavy metal stress response may be involved, we used microarray to examine gene expression changes in wild-type and kgb-1 mutant animals subjected to heavy metal stress.

Expression data for C. elegans blunt force trauma

(Submitter supplied) C. elegans exhibit an age-dependent mechanical stress response to blunt force injury. Stress responses are often defined in part by an elicited cellular transcriptional response. We find in C. elegans that mechanical stress by blunt trauma induces a distinct and age-dependent transcriptional program.

DVE-1_ChIP-seq and HDA-1_ChIP-seq of worms

(Submitter supplied) Mitochondria are important organelles, but their function is often challenged by toxic products of metabolism as well as by pathogen attack. The mitochondrial unfolded protein response (UPRmt) monitors mitochondrial function in general: it is responsible for buffering the mitochondrial protein folding environment, and controlling mitochondria-nuclear balance of the electron transport chain (ETC) components. more...

mRNA-seq of worms and the mitochondrial unfolded protein response (UPRmt)

(Submitter supplied) To cope with a challenging and unpredictable environment, living systems have evolved several organelle-specific stress responses, e.g. the cytosolic heat shock response (HSR), the endoplasmic reticulum unfolded protein response (UPRER) and the mitochondrial unfolded protein response (UPRmt). UPRmt monitors mitochondrial function and homeostasis in general. However, the mechanism of UPRmt remains largely unexplored. more...

mek-1 and mlk-1 in fed or fasted condition

(Submitter supplied) Intermittent fasting is one of the most effective dietary restriction regimens that extend life-span in C. elegans and mammals. Fasting-stimulus responses are key to the longevity response; however, the mechanisms that sense and transduce fasting-stimulus have remained largely unknown. Through a comprehensive transcriptome analysis in C. elegans, we have found that along with the FOXO transcription factor DAF-16, AP-1 (JUN-1/FOS-1) plays a central role in fasting-induced transcriptional changes. more...

A conserved JNK/AP-1 module is a key mediator of intermittent fasting-induced longevity in C. elegans

(Submitter supplied) Dietary restriction extends lifespan and delays the age-related physiological decline in many species. Intermittent fasting (IF) is one of the most effective dietary restriction regimens that extends lifespan in C. elegans and mammals1,2. In C. elegans, the FOXO transcription factor DAF-16 is implicated in fasting-induced gene expression changes and the longevity response to IF3; however, the mechanisms that sense and transduce fasting-stress stimuli have remained largely unknown. more...

Transcriptional response to stress in serum deprived mouse fibroblasts in the presence of MSK1/2 inhibitor.

(Submitter supplied) We have employed gene expression profiling in order to identify targets of transcriptional response to stress in resting mouse Swiss 3T3 fibroblasts, either untreated (control) or treated with anisomycin for 3 or 6 hours to induce the p38/MAP kinase pathway. In order determine transcriptional effects dependent on MSK1/2 kinase activity, H89 inhibitor was used in the study.

ChIP-seq analysis of the C. elegans CEBP-1 protein

(Submitter supplied) Purpose: The goal of this study is to identify genes selectively associated with C. elegans CEBP-1. Methods: We generated transgenic animals expressing FLAG-tagged CEBP-1 in a cebp-1(tm2807) mutant background (cebp-1(0); juIs418 [Pcebp-1::FLAG::CEBP-1::cebp-1 3’UTR]) and then immunoprecipitated FLAG-CEBP-1-associated DNA fragments using anti-FLAG antibodies (M2 anti-FLAG magnetic beads; Sigma). We collected mixed stage worms grown at 20˚C on NGM plates followed by 2% formaldehyde and sonicated the samples as described (Mukhopadhyay et al., 2008). more...

Expression data from serum-stimulated NIH 3T3 cells stably expressing control (pLKO.1) vector or shRNAs targeting Net or Sap-1

(Submitter supplied) Although much is known about focal adhesion signaling induced by cell adhesion, how adhesion directs changes in transcription to control cell behavior is far less understood. Here we describe a novel mechanism by which changes in adhesion switch the activities of the mitogen-activated protein kinases (MAPKs) c-Jun N-terminal kinase (JNK) and p38, resulting in the differential activation and promoter occupancy of the SRF cofactors, the ternary complex factors (TCFs) Sap-1 and Net. more...

Gene expression C. elegans age-1 mutants with neuron- or intestine-restricted age-1 activity

(Submitter supplied) The goal of this experiment was to identify transcripts regulated non-autonomously by age-1 activity in neurons or intestine. Comparisons of gene expression were made between age-1(mg44) null adults and CY251 (age-1(mg44); bvIs2) and CY262 (age-1(mg44); bvIs1); all were relative to wildtype (N2). The integrated transgenes, bvIs2 and bvIs1, carry the age-1 cDNA expressed from the neuronal ric-19 promoter (bvIs2) or intestinal ges-1 promoter (bvIs1). more...
