Microarray transcriptional profiling of three-spined stickleback (Gasterosteus aculeatus) exposed to 10 different model toxicants and 26 mixtures of these toxicants

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.

The protein profiles of washes from the body cavity of Gasterosteus aculeatus L., infected with the Schistocephalus solidus, and from the surface of the helminth

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.

Proteome of Schistocephalus solidus (Cestoda) after short- and long-term heating

Project description:The protein composition of the cestode Schistocephalus solidus was measured in an experiment simulating the transition of the parasite from a cold-blooded to a warm-blooded host. Infective S. solidus plerocercoids obtained from the three-spined stickleback Gasterosteus aculeatus were heated at 40 °C for 1 hour or cultured in vitro at 40 °C and 22 °C for 48 hours. Plerocercoids taken out from the body cavity of sticklebacks immediately after their sacrifice were used as a reference group.

Subtle effects of radiation on embryo development of the 3-spined stickleback

Project description:Following serious accidents at the Chernobyl and Fukushima nuclear power plants in 1986 and 2011 respectively, local flora and fauna have been chronically exposed to environmental radiation for many years . However, little is known about the environmental effects of low doses of radiation on aquatic organisms. The present study assesses the effect of an environmentally relevant dose range of radiation (Control: 0, Low (L): 0.1, Medium (M): 1 and High (H): 10 mGy/day) of waterborne 32P on early life stages of the 3-spined stickleback, Gasterosteus aculeatus. Here we assess the global effects on gene regulation on the embryo development of fish suffering from differing levels of environmental radiation to identify significantly altered transcriptional networks as a result of sustained radiation exposure.

Genome-wide DNA methylation profiling reveals epigenetic adaptation of stickleback to sea and freshwater conditions

Project description:Three-spined stickleback (Gasterosteus aculeatus) represents a convenient model to study microevolution - adaptation to freshwater environment. While genetic adaptations to freshwater are well-studied, epigenetic adaptations attracted little attention. In this work, we investigated the role of DNA methylation in the adaptation of marine stickleback population to freshwater conditions. DNA methylation profiling was performed in marine and freshwater populations of sticklebacks, as well as in marine sticklebacks placed into freshwater environment and freshwater sticklebacks placed into seawater. For the first time, we demonstrated that genes encoding ion channels kcnd3, cacna1fb, gja3 are differentially methylated between marine and freshwater populations. We also showed that after placing marine stickleback into fresh water, its DNA methylation profile partially converges to the one of a freshwater stickleback. This suggests that immediate epigenetic response to freshwater conditions can be maintained in freshwater population. Interestingly, we observed enhanced epigenetic plasticity in freshwater sticklebacks that may serve as a compensatory regulatory mechanism for the lack of genetic variation in the freshwater population. Some of the regions that were reported previously to be under selection in freshwater populations also show differential methylation. Thus, epigenetic changes might represent a parallel mechanism of adaptation along with genetic selection in freshwater environment.
