Different Genome Changes Observed in Cancer Cells.
Stress-Induced Mutagenic Activity |
---|
Hypermutability following loss of replication proofreading functions |
Massive genome rearrangements (“karyotype chaos”) |
Homology-independent rearrangements (NHEJ) |
Retrotransposon activation |
Non-canonical termination of homologous recombination |
Kataegis and somatic hypermutation |
Cytosine deaminase-dependent chromosome translocation |
Chromothripsis |
Chromothripsis linked to oncogene amplification |
Complex insertion-deletion mutations (indels) |
Tandem duplications as well as formation of “amplicons” with rearranged and amplified chromosomal segments, a.k.a. copy number variations (CNVs) |
Formation of amplified circular extrachromosomal DNAs |
Processed pseudogene formation |
L1 retrotransposition |
Extensive L1 retrotransduction of non-repetitive DNA |
Transfer of mitochondrial DNA into nuclear genome |
RAG transposase/recombinase-mediated chromosome rearrangement in immune system tumors |
Somatic hypermutation involving a reverse transcriptase-based mutator activity |
