TASOR expression in naive embryonic stem cells safeguards their developmental potential [CUT&TAG]

Project description:The seamless transition through stages of pluripotency relies on a delicate balance between transcription factor networks and epigenetic silencing mechanisms that ensure proper regulation of the developmental program, critical for normal development. Here, we uncover the pivotal role of the transgene activation suppressor (TASOR), a component of the human silencing hub (HUSH) complex, in sustaining cell viability during the transition from naive to primed pluripotency, despite its rapid downregulation during this transition. Loss of TASOR in naive cells triggers replication stress, disrupts H3K9me3 heterochromatin formation, and compromise the transcriptional and post-transcriptional silencing of LINE-1 (L1) transposable elements (TEs), with these effects become more pronounced in primed cells. Remarkably, the survival of Tasor-knockout cells during naive to primed transition can be restored through the inhibition of cysteine-aspartic acid protease (Caspase) or deletion of mitochondrial antiviral signaling protein (MAVS). This suggests that unscheduled L1 expression activates an innate immune response, leading to programmed cell death, specifically in cells exiting naïve pluripotency. Additionally, we propose that HUSH-promoted H3K9me3 in naïve PSCs sets the stage for ensuing DNA methylation in primed cells, establishing long-term silencing during differentiation. Our findings shed insights on the crucial impact of epigenetic programs established in early developmental stages on subsequent phases, underscoring their significance in the developmental process.

scNanoSeq-CUT&Tag: a long-read single-cell CUT&Tag sequencing method for efficient chromatin modification profiling within individual cells

Project description:We developed scNanoSeq-CUT&Tag, a streamlined method by adapting a modified CUT&Tag protocol to Oxford Nanopore sequencing platform for efficient chromatin modification profiling at single-cell resolution. We firstly tested the performance of scNanoSeq-CUT&Tag on six human cell lines: K562, 293T, GM12878, HG002, H9, HFF1 and adult mouse blood cells, it showed that scNanoSeq-CUT&Tag can accurately distinguish different cell types in vitro and in vivo. Moreover, scNanoSeq-CUT&Tag enables to effectively map the allele-specific epigenomic modifications in the human genome andallows to analyze co-occupancy of histone modifications. Taking advantage of long-read sequencing,scNanoSeq-CUT&Tag can sensitively detect epigenomic state of repetitive elements. In addition, by applying scNanoSeq-CUT&Tag to testicular cells of adult mouse B6D2F1, we demonstrated that scNanoSeq-CUT&Tag maps dynamic epigenetic state changes during mouse spermatogenesis. Finally, we exploited the epigenetic changes of human leukemia cell line K562 during DNA demethylation, it showed that NanoSeq-CUT&Tag can capture H3K27ac signals changes along DNA demethylation. Overall, we prove that scNanoSeq-CUT&Tag is a valuable tool for efficiently probing chromatin state changes within individual cells.

CUT&Tag and BioCUT&Tag enables investigation of the AT-rich and dynamic epigenome of Plasmodium falciparum from low input samples

Project description:This study aimed to adapt CUT&Tag to Plasmodium falciparum samples as an efficient and sensitive alternative to classical ChIP-sequencing. We compare H3K9me3 and HP1 CUT&Tag with ChIP-seq datasets, showing successful establishment of CUT&Tag in P. falciparum. Next we aimed to scale down required input material for our CUT&Tag reactions and generated high-quality HP1 tracks with as little as 10.000 nuclei. To minimise potential sample loss we tested feasibility of utilising (frozen) saponin parasite isolates as input material instead of nuclei, which proved to be viable. Lastly, we deployed our new technique Dimerisation-induced Biotinylation-CUT&Tag (DiBioCUT&Tag) to catch transient interactions by biotinylation of strongly associated proteins such as histones. We tested this technique on HP1 and compared standart CUT&Tag with DiBioCUT&Tag. Furthermore, we explored interactions of the transcription factor BDP5, which we were previously unable to succesfully ChIP.
