Project description:We perform promoter Capture Hi-C in human adipocytes to investigate interactions between gene promoters and distal elements as a transcription-regulating mechanism contributing to these phenotypes. We find that promoter-interacting elements in human adipocytes are enriched for adipose-related transcription factor motifs, such as PPARG and CEBPB, and contribute to heritability of cis-regulated gene expression.

Project description:Nijmegen breakage syndrome (NBS) results from the absence of the NBS1 protein, responsible for detection of DNA double-strand breaks (DSBs). NBS is characterized by microcephaly, growth retardation, immunodeficiency, and cancer predisposition. Here we show successful reprogramming of NBS fibroblasts into induced pluripotent stem cells (NBS-iPSCs). Our data suggest a strong selection for karyotypically normal fibroblasts to go through the reprogramming process. NBS-iPSCs then acquire numerous chromosomal aberrations and show a delayed response to DSB induction. Furthermore, NBS-iPSCs display slower growth, mitotic inhibition, a reduced apoptotic response to stress and abnormal cell cycle-related gene expression. Importantly, NBS neural progenitor cells (NBS-NPCs) show down-regulation of neural developmental genes, which seems to be mediated by P53. Our results demonstrate the importance of NBS1 in early human development, shed new light on the molecular mechanisms underlying this severe syndrome and further expand our knowledge of the genomic stress cells experience during the reprogramming process. Gene expression analysis was performed on a total of 6 human cell lines, including WT and NBS Neural progenitor cells (NPCs) and NBS-iPSCs

Project description:Crosslinking mass spectrometry (CXMS) is a powerful technique to study protein structures and interactions. However, software tools for CXMS data analysis suffer from poor speed and credibility, especially at a proteome scale. Here, we introduce pLink 2, a search engine with higher speed and credibility for proteome-scale identification of crosslinked peptides. With a novel two-stage open search strategy facilitated by fragment indexing, pLink 2 is ~40 times faster than pLink 1 and 3~10 times faster than Kojak. Furthermore, four new analysis methods, using simulated datasets, synthetic datasets, 15N metabolically labeled datasets, and entrapment databases, were designed to evaluate the credibility of ten state-of-the-art search engines, this systematic evaluation showed that pLink 2 achieved the highest precision and sensitivity. Finally, four whole-cell lysate datasets, previously analysed by pLink 1 in months, were reanalysed by pLink 2 only in days, with up to 27.4% more crosslinks identified. The new search engine pLink 2 and the new evaluation methods are well positioned to become new benchmarks in the CXMS research field.

Project description:The establishment of latent herpes simplex virus 1 (HSV-1) infection is controlled by promyelocytic leukemia nuclear bodies (PML NBs). Viral genomes are recruited to PML NBs structures and chromatinized by repressive H3.3K9me3 modified H3.3 histone variant to form viral DNA-containing PML-NBs (vDCP NBs). Exactly how this occurs is unclear. Here we identify an essential role for the HUSH complex and its SETDB1 and MORC2 effectors in the establishment and maintenance of latent herpes simplex virus 1 (HSV-1) infection. ChIP-seq analyses conducted on latently/quiescently infected primary human fibroblasts highlight the association of the H3K9me3 mark with the entire viral genome. We demonstrate the necessity of HUSH, SETDB1, and MORC2 in the establishment of repressive heterochromatin in vDCP NBs. Depletion of these components prior to viral infection results in reduced H3K9me3 levels across the entirety of latent/quiescent HSV-1 genomes, with minimal impact on the cellular genome as a whole. Once latency is established, depletion of HUSH, SETDB1, or MORC2 by shRNAs or the HIV-2ROD Vpx protein, induces the reactivation of HSV-1 in infected primary human fibroblasts as well as in human induced pluripotent stem cell-derived sensory neurons (hiPSDN). We discovered that the viral protein ICP0 induces MORC2 degradation via the proteasome machinery. This process is concurrent with ICP0 capability to initiate full HSV-1 reactivation, as well as the significant reactivation of HSV-1 upon MORC2 depletion in hiPSDN. Our data demonstrate the potent antiviral restriction activity of the HUSH/SETDB1/MORC2 complex to a non-integrated human herpesvirus, its close association with PML NBs, and introduces a new target for anti-herpesvirus therapy.
