GEMC1, a novel factor required for chromosomal DNA replication [PDF]

, 2009
In eukaryotic cells DNA replication begins from multiple origins. During the process of initiation, the DNA replication fork is established at each origin. In lower eukaryotes many factors required for chromosomal DNA replication have been identified.

Cytomegalovirus replicon-based regulation of gene expression in vitro and in vivo [PDF]

, 2011
There is increasing evidence for a connection between DNA replication and the expression of adjacent genes. Therefore, this study addressed the question of whether a herpesvirus origin of replication can be used to activate or increase the expression of ...

The enhancement of M13 phage titration by optimizing the origin of replication

Research in Pharmaceutical Sciences
Background and purpose: M13KO7, a modified M13 phage variant, carries the p15A replication origin and Tn903 kanamycin resistance gene. This study aimed to optimize M13KO7's replication by substituting the p15A origin with the higher-copy pMB1 origin (500-

Chromosome I controls chromosome II replication in Vibrio cholerae.

PLoS 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.

Mapping of origin of replication in Themococcales [PDF]

Bioinformation, 2010
Genome replication is a crucial and essential process for the continuity of life.In all organisms it starts at a specific region of the genome known as origin of replication (Ori) site. The number of Ori sites varies in prokaryotes and eukaryotes. Replication starts at a single Ori site in bacteria, but in eukaryotes multiple Ori sites are used for ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

DNA replication: archaeal oriGINS [PDF]

BMC Biology, 2011
GINS is an essential eukaryotic DNA replication factor that is found in a simplified form in Archaea. A new study in this issue of BMC Biology reveals the first structure of the archaeal GINS complex. The structure reveals the anticipated similarity to the previously determined eukaryotic complex but also has some intriguing differences in the relative

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Genome-wide analysis reveals extensive functional interaction between DNA replication initiation and transcription in the genome of trypanosoma brucei [PDF]

, 2012
Identification of replication initiation sites, termed origins, is a crucial step in understanding genome transmission in any organism. Transcription of the Trypanosoma brucei genome is highly unusual, with each chromosome comprising a few discrete ...
