The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]

open access: yes, 2012
Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

Lactococcus Ceduovirus Phages Isolated from Industrial Dairy Plants—From Physiological to Genomic Analyses

open access: yesViruses, 2020
Lactococcus Ceduovirus (formerly c2virus) bacteriophages are among the three most prevalent phage types reported in dairy environments. Phages from this group conduct a strictly lytic lifestyle and cause substantial losses during milk fermentation ...

Simian virus 40 DNA replication in vitro: identification of multiple stages of initiation [PDF]

open access: yes, 1989
A cell-free DNA replication system dependent upon five purified cellular proteins, one crude cellular fraction, and the simian virus 40 (SV40)-encoded large tumor antigen (T antigen) initiated and completed replication of plasmids containing the SV40 ...

The epigenetic control of E-box and Myc-dependent chromatin modifications regulate the licensing of lamin B2 origin during cell cycle [PDF]

open access: yes, 2012
Recent genome-wide mapping of the mammalian replication origins has suggested the role of transcriptional regulatory elements in origin activation. However, the nature of chromatin modifications associated with such trans-factors or epigenetic marks ...

Mutant p53 establishes targetable tumor dependency by promoting unscheduled replication [PDF]

open access: yes, 2017
Gain-of-function (GOF) p53 mutations are observed frequently in most intractable human cancers and establish dependency for tumor maintenance and progression.

Sequential early stages in the in vitro initiation of replication at the origin of the Escherichia coli chromosome.

open access: yesJournal of Biological Chemistry, 1988
Complexes previously identified in the reconstitution of stages in the initiation of replication of plasmids (oriC) bearing the origin of the Escherichia coli chromosome have been examined further.

Metazoan DNA replication origins [PDF]

open access: yesCurrent Opinion in Cell Biology, 2019
DNA replication starts with the opening of DNA at sites called DNA replication origins. From the single sequence-specific DNA replication origin of the small Escherichia coli genome, up to thousands of origins that are necessary to replicate the large human genome, strict sequence specificity has been lost.

Chromosome I controls chromosome II replication in Vibrio cholerae.

open access: yesPLoS Genetics, 2014
Control of chromosome replication involves a common set of regulators in eukaryotes, whereas bacteria with divided genomes use chromosome-specific regulators. How bacterial chromosomes might communicate for replication is not known.

The bovine papillomavirus origin of replication requires a binding site for the E2 transcriptional activator [PDF]

open access: yes, 1993
The bovine papillomavirus type I transcriptional activator E2 is essential for replication of bovine papillomavirus DNA, yet most of the high-affinity binding sites for E2 are dispensable.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
