Experimental Protocol

Wild-type ZDR zebrafish (Danio rerio) were obtained from Animal Wonders, San Marcos, TX, and Aquatica Tropicals, Plant City, FL. Fish were conditioned on a 12 hour light/dark cycle for a minimum of 14 days before use. The design of this analysis compared the experimental to the control: midnight samples were used as experimental and midday as control. Samples were collected in triplicate per time point with each replicate representing total RNA pooled from 9 fish. Dual-color microarray was used to compare the midnight and midday samples. A statistically significant (p-value ≤ 0.05) and 2-fold or more change in an experimental sample as compared to a control indicated an up- or down-regulation in gene expression. Supplementary files: In Complete processed data file, "x" marked spots show intensities of less than 1000. In Intensity trimmed data file, all genes with signal intensities of less than 1000 in all triplicate time points were removed from the analysis.
