Focal copy number
WebGenomic copy number aberrations and corresponding transcriptional deregulation in the cancer genome have been suggested to have regulatory roles in cancer development and progression. WebTo call focal amplifications (Fig. 1B), Copy-scAT generates a linear scaled profile of density over normalized 1-Mbp bins along each chromosome on a single-cell basis, centering on the median ... For larger copy number alterations, Copy-scAT pools the bins further at the chromosome arm level using a trimmed mean (keeping

WebDec 31, 2014 · Focal copy number changes were found in most samples with a median number of 26 (range: 4–61) for losses and 6 (range: 0–19) for gains per sample. We observed a total of 550 recurrent (n≥2) copy number changes. Representative examples of focal copy number changes are shown in Fig. 2. WebSep 1, 2024 · Oncogene amplification, a major driver of cancer pathogenicity, is often mediated through focal amplification of genomic segments. Recent results implicate extrachromosomal DNA (ecDNA) as the primary driver of focal copy number amplification (fCNA) - enabling gene amplification, rapid tumor evolution, and the rewiring of …
WebNov 12, 2013 · By examining regions of focal copy-number change that lack protein-coding targets, we identified an intergenic lncRNA on chromosome 1, OVAL, that shows narrow focal genomic amplification in a subset of tumors. While weakly expressed in most tumors, focal amplification coincided with strong OVAL transcriptional activation. WebA genome-wide view of the copy-number alterations is shown in Fig. 2a (LOH results are described in SI Note 1 in SI Text). The overall pattern is complex, with almost every region of the genome...
