Comparative analysis of RNA-seq data from human ALT+ cell lines treated with NR2F2 siRNA

ABSTRACT: The Alternative Lengthening of Telomeres (ALT) facilitates telomere lengthening by a DNA strand invasion and copying mechanism. The nuclear receptor NR2F2 can bind to (TCAGGG)n variant repeats within telomeres and it has been proposed that this facilitates telomere interactions in ALT+ cells. However, the role NR2F2 in regulation the gene expression in ALT+ cell lines is unclear. Here, using Next Generation Sequencing (NGS), we characterised the changes in expression profile of three ALT+ cell lines (W-V, WI38VA13/2RA, U2OS) upon transient siRNA mediated downregulation of NR2F2 compared to cells treated with a control siRNA . Among 86 ALT-associated genes, only MND1 showed consistent down-regulation across the three NR2F2-depleted ALT+ cell lines. Altogether our data indicate that NR2F2 it does not play a direct role in the ALT mechanism.

Single cell RNA-seq Analysis of Wild Type(WT), Dcaf11 knockout(KO) and Dcaf11 knockdown(KD) embryos

Project description:Telomeres play vital roles in ensuring chromosome stability and are thus closely linked with the onset of aging and human disease. Telomeres undergo extensive lengthening during early embryogenesis through the so-called alternative lengthening of telomere (ALT) mechanism. However, the detailed molecular mechanism of telomere resetting in early embryos remains unknown. Here, we showed that Dcaf11 participates in telomere elongation in early embryos and 2-cell-like embryonic stem cells (ESCs) in a telomerase-independent manner. The deletion of Dcaf11 in embryos and ESCs leads to reduced telomere sister-chromatid exchange (T-SCE) and impairs telomere lengthening. Importantly, Dcaf11-deficient mice exhibit gradual telomere erosion with successive generations, and hematopoietic stem cell (HSC) activity is greatly compromised. Mechanistically, DCAF11 reactivates Zscan4 and facilitates the removal of heterochromatic H3K9me3 at telomere/subtelomere regions through targeting TRIM28 for ubiquitination-mediated degradation. Our study therefore demonstrates that the ALT factor Dcaf11 plays important roles in telomere elongation in early embryos and ESCs.

NR2C/F orphan receptors induce telomere-genome rearrangements in ALT

Project description:Most sarcomas have complex karyotype and are characterized by multiple chromosomal rearrangements. Moreover, sarcomas very frequently maintain their telomeres by recombination in the process called Alternative Lengthening of Telomeres (ALT) which enables their continuous growth and immortalization. Previously our group showed that orphan receptors bind specifically to the ALT telomeres and that their presence is important for the ALT mechanism. In these studies we focus on the function of orphan receptors at the telomeres and their contribution to telomeric recombination. We demonstrate that orphan receptors induce proximity of their binding sites in telomeric and genomic context and reveal novel aspects of ALT which are telomere-genome rearrangements which can underlie complexity of sarcomas. Our data perturb the dogma of telomere function in protecting the genome integrity. Here we show that in some cases telomeres may in fact drive genomic instability and chromosomal rearrangements by recombination with genomic sites. Characterization of TRF2 and orphan receptor NR2F/C2 binding sites in ALT (-) and ALT (+) cells.

TERRA interactome in human ALT cancer cells identified by iDRiP-MS method

Project description:Alternative Lengthening of Telomeres (ALT) cancer cells are a subset of cancers that depend on the homologous recombination mechanism to extend their telomere length independent of telomerase. ALT cells contain elevated levels of the telomeric-repeat containing long noncoding RNA (TERRA), which is an RNA transcribed by RNA polymerase II and can form RNA:DNA (R-loops) hybrids at telomeres. Lines of evidence have shown that the formation of R-loops at telomeres could be one of the mechanisms to trigger DNA repair to lengthen telomeres. We perform iDRiP-MS, a method to capture specific RNA interacting protein by UV light crosslinking using antisense probe capture (Chu et al., 2017a; Minajigi et al., 2015), to explore the TERRA interactomes in human ALT cancer cell. Our TERRA interactome data reveals that TERRA interacts with an extensive subset of DNA repair proteins in ALT cells including the endonuclease XPF, suggesting that TERRA R-loops activate DDR via XPF to promote homologous recombination and telomere replication to drive ALT.

Mammalian telomeres reforged with non-telomeric sequences

Project description:Telomere is a highly refined system for maintaining the stability of linear chromosomes. Most telomeres rely on simple repetitive sequences and telomerase enzymes, but in some species or telomerase-defective situations, alternative telomere lengthening (ALT) mechanism is utilized to protect chromosomal ends. Telomere loss can induce telomere recombination by which specific sequences can be recruited into telomeres. However, canonical telomeric repeat-based telomeres have been found in mammals. Here, we show that mammalian telomeres can also be completely reconstituted using a non-telomeric unique sequence. We found that a specific subtelomeric element, named as mouse template for ALT (mTALT), is utilized for repairing telomeric DNA damage and composing new telomeric sequences in mouse embryonic stem cells. We found a high-level of non-coding mTALT transcript despite the heterochromatic nature of mTALT-based telomere. After ALT activation, the increased HMGN1, a non-histone chromosomal protein, contributed to maintaining telomere stability by regulating telomeric transcriptions. Our findings reveal novel molecular features of potential telomeric sequences which can reconstitute telomeres during cancer formation and evolution.

Genome profiling by comparative genomic hybridization (CGH) in pediatric osteosarcoma

Project description:In some types of cancer, telomere length is maintained by the Alternative Lengthening of Telomeres (ALT) mechanism. We characterized a series of high-grade osteosarcomas from 22 non-metastatic and non-pre-treated pediatric patients. Using the presence of circular partially single-stranded extrachromosomal C-rich telomeric repeat sequences (C-Circles) as an ALT marker, we found that 16 of the 22 high-grade osteosarcomas were ALT-positive. In order to find copy number alterations associated with ALT mechanims, we used comparative genomic hybridization (CGH).

Telomeres reforged with non-telomeric sequences in mouse embryonic stem cells (Iso-seq)

Project description:Telomere maintenance is indispensable for perpetuated cell division, but telomeres are not necessarily composed of a fixed sequence. Here we report the establishment of a model for alternative lengthening of telomeres (ALT) in mouse embryonic stem cells (mESCs) in which telomeres are reconstructed with an internal ALT template. Longitudinal whole-genome analyses of ALT mESCs showed that pre-amplification of the template into a telomeric region was a prerequisite for ALT activation, and that extensive copy number variations became concentrated in subtelomeric regions. Epigenomic analysis revealed the heterochromatic structure of the ALT telomeres, except for an insulator region within the ALT template. Quantitative proteomics followed by single-cell RNA-sequencing and functional assays revealed that HMGN1 protected new telomeres by regulating telomere repeat-containing RNA transcription and R loop formation in ALT mESCs. These findings implicate an evolutionarily conserved ALT mechanism driven by an internal template and provide a molecular basis underlying telomere evolution.
