MetabolomicsDeep functional analysis of synII, a 770 kb synthetic yeast chromosome
Here we report the design, construction and characterization of a 770 Kb synthetic yeast chromosome II (synII). With the UPLC-MS method, we demonstrated synII maintains a nearly wild-type phenotype and fitness despite hundreds of designer editing to it. Our phenomics, transcriptomics, proteomics dat...

TranscriptomicsAvoiding chromosome pathology when replication forks collide
Chromosome duplication normally initiates via the assembly of replication fork complexes at defined origins. DNA synthesis by any one fork is thought to cease when it meets another travelling in the opposite direction, at which stage the replication machinery may simply dissociate before the nascent...

TranscriptomicsReplication Timing Reveal An Epigenetic Commitment To Differentiation Prior To Germ Layer Specification (WG_CGH, RT)
Differentiation of mouse embryonic stem cells (mESCs) is accompanied by global changes in replication timing. To elucidate this reorganization process and explore its potential impact on mouse development, we constructed genome-wide replication-timing profiles of 15 independent mouse cell types repr...

TranscriptomicsAbnormal Developmental Control of Replication Timing Domains in Pediatric Acute Lymphoblastic Leukemia
Abnormal replication timing has been observed in cancer but no study has comprehensively evaluated this misregulation. We generated genome-wide replication timing profiles for pediatric leukemias from 17 patients and 3 cell lines, as well as normal B and T cells. Non-leukemic EBV-transformed lymphob...

TranscriptomicsChromosome length influences replication-induced topological stress
During chromosome duplication the parental DNA molecule becomes over-wound, or positively supercoiled, in the region ahead of the advancing replication fork. To allow fork progression this superhelical tension has to be removed by topoisomerases, which operate by introducing transient DNA breaks. Po...

TranscriptomicsGenome-wide connection between DNA methylation and DNA replication timing
DNA methylation and DNA replication timing were examined across a variety of human tissues and cell lines, applying microarray-based techniques. The analyses revealed that late-replicating DNA was demethylated compared to the methylation of early-replicating regions. DNA methylation: Epstein-Barr-Vi...

TranscriptomicsSeparation of DNA replication from the assembly of break-competent meiotic chromosomes
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up to recombination, including the prolonged pre-m...

TranscriptomicsGenome-wide Profiling of DNA Replication Timing in pombe.
DNA replication is initiated at multiple sites or origins enriched with AT-rich sequences at various times during the S-phase. While current studies of genome-wide DNA replication profiles have focused on the timing of replication and the location of origins, the efficiency of replication/firing at...
