Project description:Chromosomal instability (CIN) occurs at high frequency during early in vitro embryogenesis and is known to be associated with early embryonic loss in humans. The chromosomal stability of in vivo-conceived cleavage stage embryos largely remains unknown. Here, we applied haplotyping and copy number profiling to investigate genomic architecture of 171 single bovine blastomeres and to compare the nature and frequency of CIN between in vivo embryos, in vitro embryos produced from ovum pick up with ovarian stimulation (OPU-IVF), and in vitro produced embryos from in vitro matured oocytes without ovarian stimulation (IVM-IVF). Our data shows that CIN is significantly lower in in vivo conceived cleavage stage embryos when compared to in vitro cultured embryos, as genomic stability of single blastomeres in both IVF embryos was severely compromised (P<0.0001)

Project description:This dataset contains Xdrop followed by oxford nanopore long read sequencing performed in target tRNA gene deletion clones in HAP1 (t72) and HepG2 (t15). By applying de novo assembly based approach to Xdrop-LRS data, we identified Cas9-induced on-target genomic alteration.

Project description:Elg1, the major subunit of a Replication Factor C-like complex, is critical to ensure genomic stability during DNA replication, and is implicated in controlling chromatin structure. We investigated the consequences of Elg1 loss for the dynamics of chromatin re-formation following DNA replication. Measurement of Okazaki fragment length and the micrococcal nuclease sensitivity of newly replicated DNA revealed a defect in nucleosome re-assembly in the absence of Elg1. Using a proteomic approach to identify Elg1 binding partners, we discovered that Elg1 interacts with Rtt106, a histone chaperone implicated in replication-coupled nucleosome assembly that also regulates transcription. We find that Rtt106 recruitment to a number of promoters depends on Elg1. A central role for Elg1 is the unloading of PCNA from chromatin following DNA replication, so we examined the relative importance of Rtt106 and PCNA unloading for chromatin reassembly following DNA replication. We find that the major cause of the chromatin assembly defects of an elg1 mutant is PCNA retention on DNA following replication, with Rtt106-Elg1 interaction potentially playing a contributory role.
