Project description:Using Caenorhabditis elegans to investigate environmental cues-induced mitochondrial dysfunction, we found that exposure to electron transport chain (ETC) inhibitors at the parental generation initiates the transmission of heritable information to descendants and make descendants stress-adaptive. This mitochondrial stress adaptation phenotype can persist for at least three generations. Animals lacking histone H3K4me3 chromatin modifiers, or the methyltransferase of N6-methyldeoxyadenosine (6mA), lose the ability to initiate stress adaptation in progeny. H3K4me3 plays a role upstream of 6mA, while both mark promoter regions of mitochondrial unfolded protein response (UPR mt ) genes and activate the UPR mt pathway to alleviate mitochondrial damage.

Project description:Yilmaz2016 - Genome scale metabolic model -
Caenorhabditis elegans (iCEL1273)
This model is described in the article:
A Caenorhabditis elegans
Genome-Scale Metabolic Network Model.
Yilmaz LS, Walhout AJ.
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:In Caenorhabditis elegans, let-60 Ras controls many cellular processes, such as differentiation of vulval epithelial cells, function of chemosensory neurons, and meiotic progression in the germ line. Although much is known about the let-60 Ras signaling pathway, relatively little is understood about the target genes induced by let-60 Ras signaling that carry out terminal effector functions leading to morphological change. We have used DNA microarrays to identify 708 genes that change expression in response to activated let-60 Ras. Set of arrays organized by shared biological context, such as organism, tumors types, processes, etc. Computed

Project description:Space radiations and microgravity both could cause DNA damage in cells, but the effects of microgravity on DNA damage response to space radiations are still controversial. A mRNA microarray and microRNA microarray in dauer larvae of Caenorhabditis elegans (C. elegans) that endured spaceflight environment and space radiations environment during 16.5-day Shenzhou-8 space mission were performed. The analyzation this study are further described in Gao, Y., Xu, D., Zhao, L., Zhang, M. and Sun, Y. (2015) Effects of microgravity on DNA damage response in Caenorhabditis elegans during Shenzhou-8 spaceflight. International journal of radiation biology, 91, 531-539.

Project description:Natural genetic variation is the raw material of evolution and influences disease development and progression. To analyze the effect of the genetic background on protein expression in the nematode C. elegans (Caenorhabditis elegans), the two genetically highly divergent wild-type strains N2 (Bristol) and CB4856 (Hawaii) were compared quantitatively. In total, we quantified 3,238 unique proteins in three independent SILAC (stable isotope labeling by amino acids in cell culture) experiments. The differentially expressed proteins were enriched for genes that function in insulin-signaling and stress response pathways.

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.
