Ribosomal DNA copy number loss and sequence variation in cancer
Ribosomal DNA is one of the most variable regions in the human genome with respect to copy number. Despite the importance of rDNA for cellular function, we know virtually nothing about what governs its copy number, stability, and sequence in the mammalian genome due to challenges associated with mapping and analysis. We applied computational and droplet digital PCR approaches to measure rDNA co...
متن کاملBIRC5 Genomic Copy Number Variation in Early-Onset Breast Cancer
Background: Baculoviral inhibitor of apoptosis repeat-containing 5 (BIRC5) gene is an inhibitor of apoptosis that expresses in human embryonic tissues but it is absent in most healthy adult tissues. The copy number of BIRC5 has been indicated to be highly increased in tumor tissues; however, its association with the age of onset in breast cancer is not well understood. Methods: Forty tumor tiss...
متن کاملBalancing copy number in ribosomal DNA.
Ecologists recognize the balance of nature as a complex system that arises from interacting and connected parts; disturbing the balance can affect other species in nonlinear and dynamic ways. Like ecosystems, the cell and genome are extensively connected by an abundance of molecular interactions. Upsetting the molecular balance, through changes in gene regulation, abnormal copy number variants,...

متن کاملConcerted copy number variation balances ribosomal DNA dosage in human and mouse genomes.
Tandemly repeated ribosomal DNA (rDNA) arrays are among the most evolutionary dynamic loci of eukaryotic genomes. The loci code for essential cellular components, yet exhibit extensive copy number (CN) variation within and between species. CN might be partly determined by the requirement of dosage balance between the 5S and 45S rDNA arrays. The arrays are nonhomologous, physically unlinked in m...
