Integration activity of evolutionarily recent human retroelements Alu and LINE in tumors

ABSTRACT: The activity of mobile elements can be considered as one of the aspects of tumor genomic instability. From that perspective, it has a potential as a prognostic or diagnostic marker. In this work we attempted to assess the levels of integration activity of evolutionarily recent human retroelements (RE) in tumors and their relationship with RE transcriptional activity as well as other potential regulatory factors.To determine the integration activity of RE in tumors and to assess its correlation with RE transcriptional activity we performed a genome-wide search for tumor-specific inserts. For that we selected 20 tumor samples with higher and 20 samples with lower LINE L1 L1Hs and L1PA2 expression for further sequencing of genomic flanks of L1Hs L1PA2 and AluYa5/8 elements. Corresponding matched norm samples were used as a control.

Genome-wide identification and DNA methylation of human full-length LINE-1 (L1) retrotransposons in a panel of embryonic stem cells, induced-pluripotent stem cells and their progenitor cells

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1). The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements. This was performed in a panel of embryonic stem cells, induced-pluripotent stem cells and their progenitor cells, at different passages.

Genome-wide identification and DNA methylation of human full-length LINE-1 (L1) retrotransposons in HCT116 cells treated with 5-aza-2’-deoxycytidine.

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1). The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements. This was performed in HCT116 cells treated by the DNA methyltransferase inhibitor 5-aza-2’-deoxycytidine (5-aza) or in mock-treated cells (DMSO).

Genome-wide identification and DNA methylation of human full-length LINE-1 (L1) retrotransposons in a panel of normal and cancer cell lines.

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1). The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements. This was performed in a panel of 12 human primary or transformed cell lines (BJ, IMR90, MRC5, H1, K562, HCT116, HeLa S3, HepG2, MCF7, HEK-293, HEK-293T, 2102Ep).

LINE1 TGS mechanism mediated by SETDB1-AGO2 complex in human somatic cells [RNA-seq]

Project description:LINE1s are abundant retroelements comprising 17% of human genome. Naturally, genomic LINE1s are tightly repressed by epigenetic mechanism; however, if relieved, they can be detrimental to genome stability by their transposition capability. So, a supervising mechanism that quickly re-represses the leaky LINE1s is demanded. Here we show that de-repressed LINE1s generate small RNAs, L1-siRNAs, which SETDB1 and AGO2 recognize, then move into searching for a transcript with sequence complementarity, and ultimately re-install a repression mechanism at LINE1 5’-untranslated region (5’UTR) by depositing trimethyl-H3K9 (H3K9me3). Immunoprecipitation (IP) results showed that SETDB1, AGO2, and L1-siRNA bound to each other and Chromatin-IP-seq and small-RNA-seq results demonstrated that they sat at the same locus within the 5’UTR. SETDB1, AGO2, and L1-siRNA all were necessary for LINE1 repression, particularly the evolutionary young and transposition-competent families such as L1HS/L1PA1 and L1PA2. KAP1, which frequently partners with SETDB1 for silencing local chromatin, was dispensible for the repression of young L1PAs. Our findings indicate that, as a surveillance mechanism, the L1-siRNA-triggered, SETDB1-AGO2-effected repair of epigenetic errors at the 5’UTR establishes a homeostatic re-repression mechanism on inadvertently de-repressed LINE1 copies over the genome.

cfDNA methylation data of longitudinally collected blood plasma samples from patients with esophageal adenocarcinoma

Project description:This study aimed to evaluate the cost-effective and genome-wide cell-free reduced representation bisulfite sequencing (cfRRBS) method combined with computational deconvolution for effective disease monitoring in patients with esophageal adenocarcinoma (EAC). cfDNA methylation profiling with cfRRBS was performed on 162 blood plasma samples from 33 EAC cancer patients and 28 blood plasma samples from 20 healthy donors. In addition, for reproducibility testing purposes of the method, 9 plasma samples were re-prepped (library was re-made) and re-sequenced once (n=9) or twice (n=1). As a reference for the data deconvolution cfRRBS was performed on 7 EAC tumor tissue (FFPE) samples.
