    Abstract Summary: LINE-1 retrotransposons are frequently active in epithelial tumors. In a new study, Taylor, Wu and colleagues now describe that one of the proteins encoded by LINE-1 elements, ORF1p, is detected in the bloodstream of patients with cancer, and can be used as a noninvasive and multicancer biomarker for diagnosis or treatment monitoring.

    Abstract Detecting large genomic inversions has long been challenging. In a new study, Porubsky et al. resolve these complex rearrangements in 41 individuals and discover wide regions that undergo recurrent inversions, some of which even toggle back and forth (Porubsky et al., 2022). Many of these regions are associated with genomic disorders.

    Abstract By silencing L1 retrotransposons, DNA methylation protects mammalian genomes from potent endogenous mutagens. However, some loci can escape this repressive mechanism and become active, particularly in carcinomas. Alterations of L1 DNA methylation can also locally influence gene expression. Comprehensive measurement of L1 DNA methylation at the locus level remains challenging. Here, we present bs-ATLAS-seq, a genome-wide approach to locate full-length L1 elements in the human genome, and assess their methylation levels at single-base and single-locus resolutions. This strategy targets the youngest, and only retrotransposition-competent family, L1HS, but also detects a significant fraction of older elements (L1PA2 to L1PA8). Bs-ATLAS-seq evaluates methylation at the first 15 CpGs of L1 5' UTR, which corresponds to the first half of the sense promoter. It relies on random fragmentation of the genomic DNA, adapter ligation, bisulfite treatment and suppression PCR, and ends by asymmetrical paired-end sequencing. A dedicated pipeline provides the location of L1 elements and their methylation status, including for non-reference loci, as well as their single-molecule DNA profiles.

    Abstract Transposable element insertions can have broad effects on gene expression, ranging from new regulatory functions to pathogenic consequences by transplanting new cis-regulating elements or perturbing existing ones. Genetic manipulation of such DNA sequences can help decipher their mechanism of action. Here, we describe a CRISPR-Cas9-mediated two-step approach to precisely insert transposable elements into into the genome of cultured human cells, without scar or reporter gene. First, a double-selection cassette is inserted into the desired target locus. Once a clone containing a single copy of this cassette has been isolated, a second editing step is performed to exchange the double-selection cassette with a markerless transposable element sequence. More generally, this method can be used for knocking in any large insert without genetic markers.

    Abstract Retrotransposition of LINE-1 (L1) elements represents a major source of insertional polymorphisms in mammals, and their mutagenic activity is restricted by silencing mechanisms, such as DNA methylation. Despite a very high level of sequence identity between copies, their internal sequence contains small nucleotide polymorphisms (SNPs) that can alter their activity. Such internal SNPs can also appear in different alleles of a given L1 locus. Given their repetitive nature and relatively long size, short-read sequencing approaches have limited access to L1 internal sequence or DNA methylation state. Here, we describe a targeted method to specifically sequence more than a hundred L1-containing loci in parallel and measure their DNA methylation levels using nanopore long-read sequencing. Each targeted locus is sequenced at high coverage (~45X) with unambiguously mapped reads spanning the entire L1 element, as well as its flanking sequences over several kilobases. Our protocol, modified from the nanopore Cas9 targeted sequencing (nCATS) strategy, provides a full and haplotype-resolved L1 sequence and DNA methylation levels. It introduces a streamlined and multiplex approach to synthesize guide RNAs and a quantitative PCR (qPCR)-based quality check during library preparation for cost-effective L1 sequencing. More generally, this method can be applied to any type of transposable elements and organisms.
