Pan-cancer analysis of whole genomes identifies driver rearrangements promoted by LINE-1 retrotransposition

Abstract: downstream of the source element, in a process called 3′ transduction 7-9. L1 retrotransposons can also promote the somatic transmobilization of Alu elements, SINE-VNTR-Alu (SVA) elements and processed pseudogenes, which are copies of mRNAs that have been reverse transcribed into DNA and inserted into the genome with the machinery of active L1 elements 10-12. Approximately 50% of human tumors contain somatic retrotranspositions of L1 elements 7,13-15. Previous analyses indicate that although a fraction of soma… Show more

“…Retrotransposition activity is high in early embryo (26) and brain (37) during normal development, so potential integration of coronavirus sequence into human genome is suggested to be scrutinized for these cells. It was also reported that retrotransposon upregulation is positively correlated with tumor progression (38), causing genomic deletion, translocation and duplication (39). What's more, increased expression of retrotransposon LINE-1 contributes to age-associated in ammation in several tissues (40).…”

“…Reflecting enrichment in CNV high subtype, our LINE-1 ORF1p quantification (hereafter called LINE-1 expression) is highly correlated with genome-wide CNV (Spearman ρ=0.44, p=3.6x10 -5 , figure 4B). Strong correlation between the somatic LINE-1 insertions and structural variation was recently reported in a pan cancer study of whole genomes (Rodriguez-Martin et al, 2020) . In our data, this correlation is only partially explained by p53 mutation (partial Spearman ρ=0.31, p=0.004), suggesting that LINE-1 may have a more direct role in CNV generation and that this effect may be enhanced by the effect of p53 mutation/deletion.…”

“…It still remains to be shown that a similar interaction between LINE-1 expression and replication stress occurs in actual human cancers. Another recent study (Rodriguez-Martin et al, 2020), which looked at somatic LINE-1 insertions in nearly 3000 cancer genomes, did identify correlations between LINE-1 insertion and multiple classes of structural variation, including several instances where a structural variation could directly be attributed at an improperly repaired retrotransposition intermediate. These results provide support for a widespread LINE-1 / DNA damage relationship in cancer, but do not elucidate the changes in expression and signalling that are involved.…”
