Microarray experiment comparing gene expression in the bar-1 mutant EW15 with wild-type strain N2 in Caenorhabditis elegans

ABSTRACT: The Wnt-pathway is a key-signalling pathway in metazoans. The beta-catenins, which include bar-1, have a function in gene expression regulation in Wnt-signalling. In this study, the effect of a loss-of-function mutation (bar-1(ga80) in the strain EW15) on gene-expression was tested. To this end age-synchronized populations of both N2 (wild-type) and EW15 were grown for 48 hours at 20 degrees Celsius, after which populations were collected and total RNA was isolated. For each genotype six replicates were collected in three batches of two replicates.

Scientific reports 20140513

C. elegans is extensively used to study the Wnt-pathway and most of the core-signalling components are known. Four β-catenins are important gene expression regulators in Wnt-signalling. One of these, bar-1, is part of the canonical Wnt-pathway. Together with Wnt effector pop-1, bar-1 forms a transcription activation complex which regulates the transcription of downstream genes. The effects of bar-1 loss-of-function mutations on many phenotypes have been studied well. However, the effects on glob ...[more]

Microarray on Caenorhabditis elegans N2 and CB4856 infected with Orsay virus

Project description:This experiment investigates the gene expression differences upon Orsay virus infection in the Caenorhabdits elegans strains N2 and CB4856. Assays measuring viral load found that the N2 strain displays higher viral loads upon infection than the CB4856 strain. The goal of the experiment was to identify gene-expression differences that could explain the differences in viral load. We (mock-)infected 26h-old C. elegans populations with Orsay virus and took samples after 30h of infection. For each treatment-strain combination 8 samples were collected. Thereafter RNA was isolated, labelled, and hybridized on microarray.

Gene expression effects in Caenorhabditis elegans strains of feeding on Erwinia rhapontici or Escherichia coli

Project description:Diet can have a strong impact on development, to test this effect the strains N2, CB4856, three strains from Orsay (JU1581, JU1944, and JU1949), and three strains from Santeuil (JU1921, JU1930, and JU1932) were grown on two different food-sources. These sources were the standard lab food, Escherichia coli OP50, and the Gram-negative plant pathogen Erwinia rhapontici. The effect of these bacteria on development could also be measured by the start of reproduction, which was delayed while feeding on E. coli. To measure the transcriptional effects, age-synchronized strains were grown for 48 hours at 20 degrees Celsius. The impact of food-source on gene expression was determined by a transcriptional ruler based on the strain N2 (E-MTAB-7019).

Microarray on an infection time-series of Orsay virus in three Caenorhabditis elegans genotypes

Project description:This experiment investigates the temporal dynamics in gene expression upon Orsay virus infection in the nematode Ceanorhabditis elegans. Three different strains were infected: JU1580, N2, and CB4856. Of these, JU1580 is highly susceptible, N2 moderately susceptible, and CB4856 the most resistant strain. The goal of the experiment was to identify genes that show different expression dynamics over the time-course of the infection. We (mock-)infected 40h-old C. elegans populations with Orsay virus and took samples over a 32-hour spanning time-course. For each treatment-strain combination 12 samples were collected. Thereafter RNA was isolated, labelled, and hybridized on microarray. The gene-expression dynamics of previously identified genes (e.g. from literature and from a highly replicated N2 versus CB4856 experiment) were analyzed.

Time series of gene expression profiles from C. elegans exposed to heat-stress and during subsequent recovery

Project description:This data set provides insight into the temporal dynamics of gene expression changes during heat-stress (at 35C) and during subsequent recovery (at 20C) in Caenorhabditis elegans. Age synchronized C. elegans CB4856 hermaphrodite populations were exposed to heat stress (35C) for 0h, 0.5h, 1h, 2h, 4h, and 6h. A recovery time-series was created by using age-synchronized N2 populations exposed to heat stress (35C) for 2 hours with a subsequent recovery period of 0.5h, 1h, 1.5h, 2h, 4h, and 6h at 20C. The samples were collected at the indicated time-points during heat stress or recovery. Gene expression profiles were created using microarray technology. This data set is an extension of the data provided under accession number E-MTAB-5753 (i.e. time series describing the gene expression dynamics during heat stress of N2).

Time series experiment on L4 stage of Caenorhabditis elegans N2

Project description:This experiment investigates the transcriptional effect of age in the N2 strain of Caenorhabditis elegans during the L4 stage. The goal is to identify genes that show dynamic gene-expression patterns over time. We grew N2 populations over the course of 44 to 58 hours at 20 degrees Celsius, independent populations were harvested in hourly intervals. Thereafter RNA was isolated, labelled and hybridized on microarray. The gene expression profiles were analyzed for dynamic expression patterns using principal component analysis and k-means clustering.

Recovery time-series after increasing heat-stress exposures in Caenorhabditis elegans measured by microarray

Project description:Increased exposure to heat-stress leads to an increasingly altered transcriptome in Caenorhabditis elegans. It is however unclear how the recovery from heat-stress progresses after increased heat-stress exposures. Hence, we exposed populations of the N2 strain to a 2, 3, 4, or 6 hour heat-shock of 35 degrees Celsius and took samples from 1 - 4 hours after termination of stress. This experiment was conduced in three biological replicates.

Gene expression profiling in control, heat-shock, and recovery treatment in an introgression line population of Caenorhabditis elegans L4 larvae

Project description:This experiment investigates the genetic architecture of gene expression (eQTL) in three different treatments in an N2xCB4856 introgression line population of Caenorhabditis elegans. The goal is to compare the effect of small CB4856 introgressions in an N2 genetic background versus a previously conducted experiment using recombinant inbred lines (RILs) derived from the same parental strains. We exposed ILs to a control (56 ILs), heat-stress (56 ILs), and recovery treatment (55 ILs). Additionally, also both parental strains, N2 and CB4856 were exposed to these three treatments (in at least 3 replicas per treatment). More specifically, these three conditions can be characterized as: (i) the control treatment was grown for 48 hours at 20C, (ii) the heat-stress treatment was grown for 46 hours at 20C followed by 2 hours at 35C, and (iii) the recovery treatment was grown for 46 hours at 20C, followed by 2 hours at 35C and thereafter 2 hours at 20C. Thereafter RNA was isolated, labelled and hybridized on microarray. The gene expression profiles were used for comparison versus findings in the RIL population (E-MTAB-5779).

Gene expression of 47 Caenorhabditis elegans strains from Orsay and Santeuil

Project description:This study investigated the role of local genetic variation on gene expression. To this end, gene expression variation between strains isolated from two locations (Orsay and Santeuil) was investigated by microarray. As an outgroup the N2, CB4856, WN2001, WN2002, WN2003, JU314 and JU396 were used. Age-synchronized strains were grown for 47 hours at 20 degrees Celsius, where after strains were sampled and RNA was isolated. Labelled cRNA was hybridized to microarray to assess the impact of local genetic variation on gene expression. DNA hybridization complementing this study can be found in E-MTAB-8126.
