High-Resolution Replication Profiles Define the Stochastic Nature of Genome Replication Initiation and Termination

open access: yesCell Reports, 2013
Eukaryotic genome replication is stochastic, and each cell uses a different cohort of replication origins. We demonstrate that interpreting high-resolution Saccharomyces cerevisiae genome replication data with a mathematical model allows quantification ...

Activation of mammalian Chk1 during DNA replication arrest: a role for Chk1 in the intra-S phase checkpoint monitoring replication origin firing [PDF]

open access: yes, 2001
Checkpoints maintain order and fidelity in the cell cycle by blocking late-occurring events when earlier events are improperly executed. Here we describe evidence for the participation of Chk1 in an intra-S phase checkpoint in mammalian cells.

Plastid Division: The Origin of Replication [PDF]

open access: yesThe Plant Cell, 1998
The fact that chlorophyll-containing chloroplasts are remarkably abundant organelles in plants is obvious to anyone contemplating the verdant green expanses of most global ecosystems. For those who have viewed leaf mesophyll cells by peering down a microscope, it is also apparent that ...

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

The replication origin of a repABC plasmid

open access: yesBMC Microbiology, 2011
Background repABC operons are present on large, low copy-number plasmids and on some secondary chromosomes in at least 19 α-proteobacterial genera, and are responsible for the replication and segregation properties of these replicons.

Single molecule analysis of replicated DNA reveals the usage of multiple KSHV genome regions for latent replication. [PDF]

open access: yesPLoS Pathogens, 2011
Kaposi's sarcoma associated herpesvirus (KSHV), an etiologic agent of Kaposi's sarcoma, Body Cavity Based Lymphoma and Multicentric Castleman's Disease, establishes lifelong latency in infected cells.

The origin of replicators and reproducers [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2006
Replicators are fundamental to the origin of life and evolvability. Their survival depends on the accuracy of replication and the efficiency of growth relative to spontaneous decay. Infrabiological systems are built of two coupled autocatalytic systems, in contrast to minimal living systems that must comprise at least a metabolic subsystem, a ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

A Unifying Scenario on the Origin and Evolution of Cellular and Viral Domains [PDF]

open access: yes, 2009
The cellular theory on the nature of life has been one of the first major advancements in biology. Viruses, however, are the most abundant life forms, and their exclusion from mainstream biology and the Tree of Life (TOL) is a major paradox in biology ...
