WebDec 15, 2015 · Chromosomal rearrangements have long been recognized as oncogenic drivers in hematological malignancies. Although it has been predicted in early 2000 that chromosomal rearrangements will be found in solid malignancies there was no reports of such rearrangements well into the mid 2000s [ 1 ]. WebFusion genes are structural chromosomal rearrangements resulting in the exchange of DNA sequences between genes. This results in the formation of a new combined gene. …
WebIdentification of distinct classes of ETS gene rearrangements demonstrates that dormant oncogenes can be activated in prostate cancer by juxtaposition to tissue-specific or ubiquitously active genomic loci. Subversion of active genomic regulatory elements may serve as a more generalized mechanism for carcinoma development. WebIn cancer cells, where reorganization of the nuclear architecture may occur in the presence of chromosomal rearrangements such as translocations, inversions, or deletions, gene repositioning can change their expression. To date, very few studies have focused on radial gene positioning and the correlation to gene expression in cancers.
