Understanding how vertebrates respond to hypoxia can have important clinical implications. Fish have evolved the ability to survive long exposure to low oxygen levels. However, little is known about the specific changes in gene expression that result from hypoxia. In this study we used a zebrafish cDNA microarray to examine the expression of >4,500 genes in(More)
The multi-subunit NADH-ubiquinone oxidoreductase (complex I) is the first enzyme complex in the electron transport chain of mitochondria. A small number of NADH-ubiquinone oxidoreductase subunits are the products of mitochondrial genes (subunits 1-7), while the remainder are nuclear encoded and imported from the cytoplasm. We have isolated and sequenced(More)
The application of expressed sequence tag (EST) technology has proven to be an effective tool for gene discovery and the generation of gene expression profiles. The generation of an EST resource for the cardiovascular system has revealed significant insights into the changes in gene expression that guide heart development and disease. Furthermore, an(More)
Vertebrate embryogenesis is a complex process controlled by a transcriptional hierarchy that coordinates the action of thousands of genes. To identify and analyze the expression patterns of these genes, we constructed a zebrafish cDNA microarray containing 4512 unique genes identified from zebrafish embryonic heart, adult hearts, and skeletal muscle cDNA(More)
The generation of expressed sequence tags (ESTs) has proven to be a rapid and economical approach by which to identify and characterize expressed genes. We generated 5102 ESTs from a 3-d-old embryonic zebrafish heart cDNA library. Of these, 57.6% matched to known genes, 14.2% matched only to other ESTs, and 27.8% showed no match to any ESTs or known genes.(More)
