A Dynamic Stochastic Model for DNA Replication Initiation in Early Embryos [PDF]

, 2008
Background: Eukaryotic cells seem unable to monitor replication completion during normal S phase, yet must ensure a reliable replication completion time.

Smc5/6 coordinates formation and resolution of joint molecules with chromosome morphology to ensure meiotic divisions [PDF]

, 2013
During meiosis, Structural Maintenance of Chromosome (SMC) complexes underpin two fundamental features of meiosis: homologous recombination and chromosome segregation.

Reversal of terminal differentiation and control of DNA replication [PDF]

, 1993
DNA replication in mammalian cells occurs in discrete nuclear foci. Here we show that terminally differentiated myotubes can be induced to reenter S phase and show the same pattern of replication foci as cycling cells.

Characterization and consequences of Telomere replication gone awry [PDF]

, 2008
Telomeres, the ends of linear eukaryotic chromosomes, pose several unique challenges to genome stability. My thesis work is concerned with the difficulties the replication machinery encounters when attempting to replicate telomeres, and with possible ...

Self-assembly and DNA binding of the blocking factor in X chromosome inactivation [PDF]

, 2007
X chromosome inactivation (XCI) is the phenomenon occurring in female mammals whereby dosage compensation of X-linked genes is obtained by transcriptional silencing of one of their two X chromosomes, randomly chosen during early embryo development. The

Differences of size and shape of active and inactive X-chromosome domains in human amniotic fluid cell nuclei [PDF]

, 1993
It is a widely held belief that the inactive X-chromosome (Xi) in female cell nuclei is strongly condensed as compared to the largely decondensed active X-chromosome (Xa).

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]

, 2007
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.

Transcription-mediated organization of the replication initiation program across large genes sets common fragile sites genome-wide

Nature Communications, 2019
Common Fragile Sites (CFSs) are chromosome regions prone to breakage upon replication stress known to drive chromosome rearrangements during oncogenesis.

Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

Advanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.

Molecular bases underlying chromosome fragility at Replication Slow Zones in Saccharomyces cerevisiae [PDF]

, 2009
Chromosome rearrangements such as translocations and deletions are frequently associated with human cancers. Such rearrangement of the chromosome can be initiated by a DNA break (DSB) that, when inappropriately repaired, may alter chromosome structure ...
