Assessing L1 retrotransposition events in human iPSCs through deep sequencing.
TDP-43 safeguards the embryo genome from L1 retrotransposition
Somatic L1 retrotransposition events have been shown to occur in epithelial cancers1-8. Here, we attempted to determine how early somatic L1 insertions occurred during the development of gastrointestinal (GI) cancers. Using L1-targeted resequencing (L1-seq), we studied different stages of four color...

Profiling of L1 retrotransposition in human neurons across brain regions
Somatic L1 Retrotransposition of Colorectal Tumors
L1 retrotransposons are active elements in the genome, capable of mobilization in neuronal progenitor cells. Previously, we showed that chromatin remodeling during neuronal differentiation allows for a transient stimulation of L1 transcription. The activity of L1 retrotransposons during brain develo...

We report that TAR DNA binding protein 43 (TDP-43), mutations in which constitute a major risk factor for amyotrophic lateral sclerosis (ALS), inhibits L1 retrotransposition in mouse embryonic stem cells (mESCs) and preimplantation embryos. Knockdown of TDP-43 resulted in massive genomic L1 expansio...

We used ATLAS-seq-neo to map the sites of integration of an engineered LINE-1 (L1) retrotransposon into the genome of HeLa S3 cells. In brief, we transfected cells with a plasmid-borne L1.3 element carrying a neomycin-resistance-based retrotransposition cassette, as well as a hygromycin-resistance c...
