DNA structure-induced genomic instability in vivo.
Noncanonical DNA structures are postulated to be responsible for some breakpoint hotspots that occur frequently in cancers. We developed a novel mouse model system using the naturally occurring H-DNA structure that deviate from the familiar right-handed helical B form found at the breakage hotspot in the human c-MYC promoter and a Z-DNA-forming CG repeat to test this idea directly. Large-scale ...
متن کاملDetection of cis- and trans-acting Factors in DNA Structure-Induced Genetic Instability Using In silico and Cellular Approaches
Sequences that can adopt alternative DNA structures (i.e., non-B DNA) are very abundant in mammalian genomes, and recent studies have revealed many important biological functions of non-B DNA structures in chromatin remodeling, DNA replication, transcription, and genetic instability. Here, we provide results from an in silico web-based search engine coupled with cell-based experiments to charac...
متن کاملPersistent genetic instability in cancer cells induced by non-DNA-damaging stress exposures.
A hallmark of cancer cells is their pronounced genetic instability, which has been implicated in both tumor development and negative treatment outcomes. Recently, it has been reported that ionizing radiation may induce a persistent state of hypermutability in mammalian cells that lasts for many (>30) cell divisions. In this study, we examined whether other stress signals (both DNA-damaging non-...
متن کاملGenetic instability induced by overexpression of DNA ligase I in budding yeast.
Recombination and microsatellite mutation in humans contribute to disorders including cancer and trinucleotide repeat (TNR) disease. TNR expansions in wild-type yeast may arise by flap ligation during lagging-strand replication. Here we show that overexpression of DNA ligase I (CDC9) increases the rates of TNR expansion, of TNR contraction, and of mitotic recombination. Surprisingly, this effec...
متن کاملGenetic instability induced by the tumor microenvironment.
The tumor microenvironment is characterized by regions of fluctuating hypoxia, low pH, and nutrient deprivation. To determine the genetic consequences of growth under these conditions, we used a tumorigenic cell line carrying a recoverable, chromosomally based lambda phage shuttle vector designed to report mutations without the need for genetic selection of mutant cells. The cells were grown in...
