What is the background of the project?
Identify genes and neuroendocrine mechanisms controlling behavior and stress responses in zebrafish. Behavioral studies include studies on aggressive behavior, risk taking, and learning. Gene expression (by quantifying mRNA concentrations) is studied in separate areas of the zebrafish brain. The project also includes analyses of monoamines (norepinephrine, dopamine and serotonin) and their metabolites in brain tissue. To identify mechanisms controlling the behavioral profile in zebrafish. Interaction between genetic background and environmental cues in forming divergent phenotypes. Behavioral observation of zebrafish, observation is performed manually (e.g. aggressive interaction) or by computerized video tracking systems. Then we will dissect sample brains from zebrafish to isolate specific brain areas. Then extract mRNA from isolated brain areas and synthesize cDNA by reverse transcriptase from this mRNA. Following that we quantify mRNA concentrations from individual brain areas using quantitative polymerase chain reaction (qPCR). Next step is to extract monoamine neurotransmitters (dopamine, norepinephrine, serotonin and their metabolites) from brain tissue and analyze the concentration of these compounds using high performance liquid chromatography (HPLC) with electrochemical detection.
