Zebrafish Genomic Library in Yeast Artificial Chromosomes.

We have constructed a zebrafish yeast artificial chromosome (YAC) library using genomic DNA isolated from the inbred AB zebrafish strain. The average insert size is 470 kb, estimated from analysis of 155 random selected YACs. The library consists of 17,000 clones, providing about a 4.

A far upstream cis-element is required for Wilms' tumor-1 (WT1) gene expression in renal cell culture.

To identify novel cis-regulatory elements responsible for the tissue-restricted expression pattern of the Wilms' tumor-1 (WT1) gene, we mapped a total of 11 DNase I-hypersensitive sites in the 5'-flanking region and first intron of the human gene, six of which were specific for WT1 expressing cell lines. A 1.4-kilobase (kb) fragment from the mouse wt1 5'-flanking region contained cross-hybridizing sequence with significant homology to a region of DNase I hypersensitivity in the human WT1 gene which bound to nuclear matrix in human fetal kidney 293 cells.
