Project description:A unique allele of MAP kinase, mpk-1(ga111), displays a reversible, temperature-sensitive, tissue-specific defect in progression through meiotic prophase I. We performed gene expression profiling on mpk-1(ga111) animals at multiple times after shift to permissive temperature to identify candidate downstream effectors of MPK-1 signaling in the germline. This analysis delineated a cohort of genes whose expression requires MPK-1 (MAP kinase) signaling in germ cells in the pachytene stage of meiosis I. Keywords: Timecourse of C. elegans mpk-1 mutants

This analysis delineated a cohort of genes whose expression requires MPK-1 (MAP kinase) signaling in germ cells in the pachytene stage of meiosis I. We analyzed six timepoints after MAP kinase mpk-1(ga111) mutants were shifted to a temperature permissive for meiotic progression. Each timepoint was sampled in triplicate. Control (mpk-1+) animals were sampled in triplicate at the beginning and end of the time series. All samples were compared to a common reference sample made of a mixture of both control samples.

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:Graphene oxide (GO) holds high promise for diagnostic and therapeutic applications in nanomedicine but reportedly displays immunotoxicity, underlining the need for developing functionalized GO with improved biocompatibility. Here, we study the adverse effects of GO and amino-functionalized GO (GONH2) during Caenorhabditis elegans development and ageing upon acute or chronic exposure. Chronic GO treatment throughout the C. elegans development causes decreased fecundity and a reduction of animal size, while acute treatment does not lead to any measurable physiological decline. However, RNA-Seq data reveal that acute GO exposure induces innate immune gene expression. The p38 MAP kinase, PMK-1, which is a well-established master regulator of innate immunity, protects C. elegans from chronic GO toxicity, as pmk-1 mutants show reduced tissue-functionality and facultative vivipary. In a direct comparison, GONH2 exposure does not cause detrimental effects in the wild type or in pmk-1 mutants, and the innate immune response is considerably less pronounced. Our work establishes the enhanced biocompatibility of amino-functionalized GO in a whole-organism, emphasizing its potential as biomedical nanomaterial.
