Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to GO and rGO on nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments using age synchronized young adult C. elegans population exposed to GO and rGO for 24h. We used whole genome microarrays to screen for global changed in C. elegans transcription profiles and with subsequent quantitative analysis conducted on selected genes.
Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to UV, TiO2 and UV+TiO2 on nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments using age synchronized young adult C. elegans population exposed to UV, TiO2 and UV+TiO2 for 24h. We used whole genome microarrays to screen for global changed in C. elegans transcription profiles and with subsequent quantitative analysis conducted on selected genes.
Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:Caenorhabditis elegans were exposed at EC30 for 48 hr at L1 stage to ZnSO4, pristine ZnO-MNPs, phosphate aged pZnO-MNPs and sulfidized sZnO-MNPs Whole genome whole trascript microarrays were used to examine and compare global gene expression profiles among treatments
Project description:We have adapted the eXcision Repair-sequencing (XR-seq) method to generate single-nucleotide resolution dynamic repair maps of UV-induced cyclobutane pyrimidine dimers (CPD) photoproducts in the Caenorhabditis elegans (C. elegans) genome.

A Caenorhabditis elegans
Genome-Scale Metabolic Network Model.

Cell Syst 2016 May; 2(5): 297-311
Abstract:
Caenorhabditis elegans is a powerful model to study
metabolism and how it relates to nutrition, gene expression,
and life history traits. However, while numerous experimental
techniques that enable perturbation of its diet and gene
function are available, a high-quality metabolic network model
has been lacking. Here, we reconstruct an initial version of
the C. elegans metabolic network. This network model
contains 1,273 genes, 623 enzymes, and 1,985 metabolic
reactions and is referred to as iCEL1273. Using flux balance
analysis, we show that iCEL1273 is capable of representing the
conversion of bacterial biomass into C. elegans biomass
during growth and enables the predictions of gene essentiality
and other phenotypes. In addition, we demonstrate that gene
expression data can be integrated with the model by comparing
metabolic rewiring in dauer animals versus growing larvae.
iCEL1273 is available at a dedicated website
(wormflux.umassmed.edu) and will enable the unraveling of the
mechanisms by which different macro- and micronutrients
contribute to the animal's physiology.

Project description:Recombinant inbred lines were created by crossing the alpha-synuclein containing Caenorhabditis elegans strains NL5901 and SCH4856. These strains contain the human alpha-synuclein gene fused to YFP and under the control of an unc-54 promotor (unc-54p::alpha-synnuclein::YFP) in an N2 and CB4856 genetic background, respectively. These two strains were used to generate a total of 212 recombinant inbred lines, of which 88 were genotyped by whole-genome sequencing using a MiSeq. These recombinant inbred lines can be used for mapping genetic modifiers affecting protein accumulation.
