Project description:Adult female three-spined stickleback fish (Gasterosteus aculeatus) were exposed to 10 individual chemicals, 26 mixtures of these chemicals, or control conditions in a flow-through system for 4 days. Transcriptomics was performed on liver samples by microarray. The main aims were to determine molecular signatures induced by these chemicals in the three-spined stickleback, discover whether these persisted in chemical mixtures and identify non-additive molecular responses in chemical mixtures exposures.
Project description:The aim of this study was to describe the excretory–secretory proteins from the helminth Schistocephalus solidus and its intermediate host, the three-spined stickleback Gasterosteus aculeatus L., which are likely to be involved in interactions between them. Combined samples of washes from the G. aculeatus sticklebacks cavity infected with the S. solidus, and washes from the parasite surface were used as experimental samples (samples 5 to 8), while washes from the uninfected fish body cavity were used as control (samples 1 to 4). The obtained samples were analyzed using mass-spectrometry nLC–MS/MS.

Project description:In order to identify gene expression difference between marine and freshwater stickleback populations, we compared the transcriptomes of seven adult tissues (eye, gill, heart, hypothalumus, liver, pectoral muscle, telencephalon) between a marine population sampled from the mouth of the Little Campbell river in British Columbia (LITC) and a freshwater population (Fishtrap Creek, FTC) from northern Washington. For each population, the sampled individuals were the lab-reared progeny of a single pair of wild-caught parents.
