Project description:The presence of numerous chemical contaminants from industrial, agricultural, and pharmaceutical sources in water supplies poses a potential risk to human and ecological health. Current chemical analyses suffer from limitations including chemical coverage and high cost, and broad-coverage in vitro assays such as transcriptomics may further improve water quality monitoring by assessing a large range of possible effects. Here, we used high-throughput transcriptomics to assess the activity induced by field-derived water extracts in MCF7 breast carcinoma cells.
Project description:To assess the impact of surface water across the Hun River, several sampling sites located in the mainstream and the tributary were selected representative of pollution gradient and different pollution source. Human mesenchymal stem cells were exposed to organic extracts of surface water from six sites for 2 days. Microarrays were used to measure the gene expression. And the gene expression profiles were used to evaluate the ability of determine the potential biological effects, to differentiate different pollution source, and to identify the toxic components.
Project description:Mice received 10 mg/L Cd in drinking water for 20 weeks, or normal water. At time of sacrifice, the lung tissue was harvested and RNA was extracted.
Project description:Jaculus jaculus were split into three experimental groups: control (water access ad libitum), dehydrated (11 days water restriction), and rehydrated (7 days water restriction followed by 3 days water ad libitum). Kidney samples were extracted and sequenced to investigate changes in gene expression during osmotic challenge in a desert adapted model.
