A 1,934-bp muscle-specific promoter from the zebrafish mylz2 gene was isolated and characterized by transgenic analysis. By using a series of 5' promoter deletions linked to the green fluorescent protein (gfp) reporter gene, transient transgenic analysis indicated that the strength of promoter activity appeared to correlate to the number of muscle(More)
We cloned and mapped two novel zebrafish genes, cxcr4a and cxcr4b, which are closely related to mammalian CXCR4. Expression analysis by reverse transcription-polymerase chain reaction and in situ hybridization demonstrated that these two genes are expressed in most cell lineages known to express Cxcr4 in mammals. These genes are co-expressed in lateral(More)
The zebrafish is widely used for functional studies of vertebrate genes. It is accessible to manipulations during all stages of embryogenesis because the embryo develops externally and is optically transparent. However, functional studies conducted on the zebrafish have been generally limited to the earliest phase of activity of the gene of interest, which(More)
