Yilmaz2016 - Genome scale metabolic model - Caenorhabditis elegans (iCEL1273)

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.

Expression data from Caenorhabditis elegans L1-stage larvae exposed to ethidium bromide and/or serial ultraviolet C radiation

Project description:Ultraviolet C radiation (UVC) damages the nuclear and mitochondrial genomes; this damage is repaired in the nuclear but not mitochondrial genome. Ethidium bromide (EtBr) inhibits mitochondrial DNA replication. We were interested in the transcriptomic response to exposure to UVC, EtBr, and the combination. The UVC exposure protocol results in a high level of mitochondrial DNA damage, and a low level of nuclear DNA damage (because of repair). We exposed age-matched L1-stage Caenorhabditis elegans to ultraviolet C radiation (UVC ) three times, separated in time by 24 h, in the absence of food. After the third exposure, larvae were placed on K agar plates with OP50 bacterial food. In some cases ethidium bromide was also used. Nematodes were sampled for RNA isolation several times.

Synergistic effects of space radiation and microgravity (miRNA WT and dys-mutant)

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.

Deep sequencing of C. elegans microRNAs under starvation conditions

Project description:In nature, animals often face feast or famine conditions. We aimed to identify the miRNAs of Caenorhabditis elegans that changed their expression under starvation conditions in stage L4 larvae. Our results highlight 14 miRNAs that show differential expression in starved versus well-fed larvae. In particular, miRNAs of the miR-35-3p/miR-41-3p family were upregulated 6-20 fold upon starvation. We verified the upregulation of miR-35-3p with qPCR. Additionally, we showed that the expression of gld-1, important in ovogenesis, and a validated target of miR-35-3p, was downregulated when the expression of miR-35-3p was higher. This study represents a starting point for a more comprehensive understanding of the role of miRNAs during starvation in C. elegans.
