As part of the effort to sequence the genome of Rattus norvegicus, we constructed a physical map comprised of fingerprinted bacterial artificial chromosome (BAC) clones from the CHORI-230 BAC library. These BAC clones provide approximately 13-fold redundant coverage of the genome and have been assembled into 376 fingerprint contigs. A yeast artificial chromosome (YAC) map was also constructed a...
cDNA probe confirmed that BRRN1 maps to chromosome 2 Localization of BRRN1, the Human (Fig. 1A) (14). To identify BRRN1-containing YAC clones we screened the Homologue of Drosophila barr, CEPH-Mark II YAC library by PCR. We used two oligonucleoto 2q11.2 tide primer pairs designed to yield PCR products corresponding to positions 448–625 (primer set I) and 2229–2402 Olga A. Cabello,* Antonio Bald...
Partner sites of 14q32 translocations found in B-cell malignancies were detected by fluorescence in situ hybridization (FISH) using yeast artificial chromosome (YAC) clones, Y20 and Y6, containing the human Ig heavy chain (IgH) gene locus. Y20 spans a 160-kb upstream and 40-kb downstream region of the JH segments on chromosome band 14q32.33. Y6 is 300-kb upstream of Y20, and spans a further 320...
Many infectious diseases of global impact are caused by parasites. This includes diseases with protozoan etiology, such as malaria, African sleeping sickness, Chagas disease, toxoplasmosis, and amoebiasis, as well as diseases caused by metazoa, such as river blindness, schistosomiasis, ecchinococcosis, and ascariasis. Combined, parasitic diseases affect more than half the world's human populati...
The lin-29 gene product of C.elegans activates a temporal developmental switch for hypodermal cells. Loss-of-function lin-29 mutations result in worms that fail to execute a stage-specific pattern of hypodermal differentiation that includes exist from the cell cycle, repression of larval cuticle genes, activation of adult cuticle genes, and the cessation of molting. Combined genetic and physica...
The transcription factor Pax6 is a crucial regulator of eye and central nervous system development. Both the spatiotemporal patterns and the precise levels of Pax6 expression are subject to tight control, mediated by an extensive set of cis-regulatory elements. Previous studies have shown that a YAC reporter transgene containing 420 Kb of genomic DNA spanning the human PAX6 locus drives express...
Representational difference analysis (RDA), a subtractive hybridization method that enriches differences between complex genomes, can be used to isolate fragments deleted in tumor genomes. Usually, most of the clones obtained by this approach result from polymorphic fragments. Therefore, identification of homozygously deleted fragments, which can indicate the presence of tumor suppressor loci, ...
To determine the chromosomal positions of expressed rice genes, we have performed an expressed sequence tag (EST) mapping project by polymerase chain reaction-based yeast artificial chromosome (YAC) screening. Specific primers designed from 6713 unique EST sequences derived from 19 cDNA libraries were screened on 4387 YAC clones and used for map construction in combination with genetic analysis...
Yeast artificial chromosomes (YACs) with inserts averaging hundreds of kilobases in size have proven very useful for the construction of physical maps of large genomes (1). However, YACs are not ideal large-insert clones. For example, the frequent occurrence of chimeric inserts complicates the use of YACs for physical mapping, walking from insert ends, and determination of contiguous DNA sequen...
The predominant genetic defect causing p47phox –deficient chronic granulomatous disease (A47 8 CGD) is a GT deletion ( D GT) at the beginning of exon 2. No explanation exists to account for the high incidence of this single mutation causing a rare disease in an unrelated, racially diverse population. In each of 34 consecutive unrelated normal individuals, both the normal and mutant D GT sequenc...
