c-MYC-induced genomic instability.
MYC dysregulation initiates a dynamic process of genomic instability that is linked to tumor initiation. Early studies using MYC-carrying retroviruses showed that these viruses were potent transforming agents. Cell culture models followed that addressed the role of MYC in transformation. With the advent of MYC transgenic mice, it became obvious that MYC deregulation alone was sufficient to init...
متن کاملMyc Oncogene-Induced Genomic Instability: DNA Palindromes in Bursal Lymphomagenesis
Genetic instability plays a key role in the formation of naturally occurring cancer. The formation of long DNA palindromes is a rate-limiting step in gene amplification, a common form of tumor-associated genetic instability. Genome-wide analysis of palindrome formation (GAPF) has detected both extensive palindrome formation and gene amplification, beginning early in tumorigenesis, in an experim...
متن کاملCDK4 deficiency promotes genomic instability and enhances Myc-driven lymphomagenesis.
The G1 kinase CDK4 is amplified or overexpressed in some human tumors and promotes tumorigenesis by inhibiting known tumor suppressors. Here, we report that CDK4 deficiency markedly accelerated lymphoma development in the Eμ-Myc transgenic mouse model of B lymphoma and that silencing or loss of CDK4 augmented the tumorigenic potential of Myc-driven mouse and human B cell lymphoma in transplant ...
متن کاملDNA 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 کاملMalaria-Induced B Cell Genomic Instability
Nussenzweig and colleagues evaluate genomic instability and germinal center derived lymphomagenesis in mice infected with Plasmodium to recreate some of the hallmark characteristics of Burkitt lymphoma, a form of cancer more common in parts of Africa where malaria is endemic.
