Targeted chromosomal deletions and inversions in zebrafish.
Zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) provide powerful platforms for genome editing in plants and animals. Typically, a single nuclease is sufficient to disrupt the function of protein-coding genes through the introduction of microdeletions or insertions that cause frameshifts within an early coding exon. However, interrogating the function of...
متن کاملRobust dosage-PCR for detection of heterozygous chromosomal deletions.
Robust dosage-PCR (RD-PCR) was developed to detect heterozygous large deletions, an important class of mutations missed by conventional PCR strategies. PCR-based methods are available for distinguishing between the dosage of one or two template copies, but general application is limited by the laborious nature of the method and/or the optimization required for each new set of gene exons to be a...
متن کاملHomozygous deletions within chromosomal bands 9p21-22 in bladder cancer.
The loss of DNA sequences on chromosomal bands 9p21-22 has been documented in a variety of malignancies including leukemias, gliomas, lung cancers, and melanomas. Because of the high incidence of monosomy 9 detected by both cytogenetics and loss of heterozygosity studies in bladder cancer, we examined seven bladder cancer cell lines for deletions in this region. Using seven DNA probes that span...
متن کاملChromosomal deletions in bladder cancer: shutting down pathways.
Bladder cancer is one of the most common cancers in the world, leading to approximately 145,000 deaths annually. Bladder cancer is typically managed by surgical removal of the tumor; however, the recurrence rate is disappointingly very high, often requiring systemic chemotherapy. Improvement in the diagnosis and prognosis of bladder cancer will only come from a comprehensive understanding of th...
متن کاملTargeted chromosomal deletions in human cells using zinc finger nucleases.
We present a novel approach for generating targeted deletions of genomic segments in human and other eukaryotic cells using engineered zinc finger nucleases (ZFNs). We found that ZFNs designed to target two different sites in a human chromosome could introduce two concurrent DNA double-strand breaks (DSBs) in the chromosome and give rise to targeted deletions of the genomic segment between the ...
