Molecular Genetics of Zebrafish Circadian Rhythmicity

Most organisms display daily changes at molecular, cellular, physiological, and behavioral levels, which is known as circadian rhythms. Circadian clocks control fundamental processes such as the human sleep-wake cycle. Many human sleep disorders are thought to result from circadian defects. A full molecular and genetic understanding of circadian rhythmicity could help cure human dysrhythmias.

We use the zebrafish (Danio rerio) as our model because it allows for a unique approach that integrates molecular, developmental, genetic and genomic techniques. We isolate zebrafish circadian clock genes and circadian clock-controlled genes and profile oscillating patterns of these genes in early embryos and organs such as the brain and the eyes. To elucidate the functions of these genes, we overexpress these genes and "knock them down" in living zebrafish embryos. We generate transgenic zebrafish using putative promotes of the selected circadian clock genes ligated with jellyfish green fluorescent protein (GFP). Those GFP-oscillating zebrafish will be mutagenized and screened for circadian mutants.
