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. Young adults of C.elegans were selected for RNA extraction and hybridization on Affymetrix microarrays.
Project description:we used short-reads to perform a comparative analysis S. carpocapsae ALL strain IJs and young adults and C.elegans dauer strain N2 and young adult strain him-8.
Project description:Gene expression analysis was conducted on the wildtype Caenorhabditis elegans exposed to silver nanoparticles (AgNPs) using whole genome microarray. Differentially expressed genes from the microarray were selected for the quantitative analysis. The microarray study was conducted in an ecotoxicological context: the integration of gene expression with organism and population level endpoints (survival, growth, reproduction) was investigated, to test the ecotoxicological relevance of AgNPs-induced gene expression. Results provide insight into the global transcription response of C.elegans to AgNPs exposure and also contribute to enhance the potential of C.elegans microarray in ecotoxicology (ecotoxicogenomics). key word: ecotoxicogenomics Experiment Overall Design: Young adults of wildtype C.elegans from age-synchronized population were exposed to 0.1mg/L of AgNPs for 24 h and RNA extraction and hybridization were subsequently conducted using C.elegans Genome array (Affymetrix).
Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to multiwall carbon nanotube (MWCNT) on the soil nematode, Caenorhabditis elegans. We performed whole genome DNA microarray experiments with subsequent quantitative analysis conducted on selected genes. We used synchronized C. elegans populations exposed to MWCNT for 4 and 24h, and whole genome microarrays to screen for global changes in C. elegans transcription profiles. Young adults of C.elegans were selected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Gene expression analysis was conducted on the wildtype Caenorhabditis elegans exposed to bisphenol A (BPA), di(2-ethylhexyl) phthalate (DEHP) and nonylphenol (NP) using whole genome microarray. The microarray study was conducted in an ecotoxicological context, by investigating the response of global gene expression with that of classical toxicological endpoints, such as, mortality, growth, reproduction and development. Results provide insight into global transcription response of C.elegans to these endocrine disrupting chemicals exposure and also contribute to enhance the potential of C.elegans microarray in ecotoxicology (ecotoxicogenomics). key word : ecotoxicogenomics Experiment Overall Design: Young adults of wildtype C.elegans from age-synchronized population were exposed to NP, DEHP and BPA at the concentrations equivalent to 1/100 of 24h LC50 of each chemical, for 24 h and RNA extraction and hybridization were subsequently conducted using C.elegans Genome array (Affymetrix).
