The In Vitro Transgenic Rodent Assay in Primary MutaMouse Hepatocytes Compared to the Mammalian Cell Gene Mutation Assay Using the HPRT Gene

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.

The virulence regulator VirB from Shigella flexneri uses a CTP-dependent switch mechanism to activate gene expression

open access: yesNature Communications
The transcriptional antisilencer VirB acts as a master regulator of virulence gene expression in the human pathogen Shigella flexneri. It binds DNA sequences (virS) upstream of VirB-dependent promoters and counteracts their silencing by the nucleoid ...

Comparison of bacterial communities of tilapia fish from Cameroon and Vietnam using PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) [PDF]

open access: yes, 2009
Fishes in general and tilapia in particular are traded all over the world. However, it is difficult to find out their exact geographical location. One of the techniques used in the traceability of fish and its byproducts consist in analysing in a global ...

Predictive value of seizure onset for gross motor dysfunction in individuals with pathogenic GABRB2 and GABRB3 variants

open access: yesEpilepsia, EarlyView.
Abstract Objective Pathogenic variants in γ‐aminobutyric acid type A (GABAA) receptor genes have been associated with a wide spectrum of neurological disorders. We aimed to delineate the clinical trajectories associated with gain‐of‐function (GoF) and loss‐of‐function (LoF) variants in GABRB2 and GABRB3, and to develop a risk‐prediction model for gross

Mechanisms of SCN2A loss of function do not predict presence or phenotype of epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective SCN2A loss‐of‐function (LoF) variants are associated with epilepsy (onset age ≥ 3 months), intellectual disability (ID), and autism spectrum disorder (ASD). Despite numerous identified variants and the description of phenotypic subgroups, relationships between Nav1.2 channel dysfunction and clinical phenotypes remain unclear.

Multimodal approach to characterize surgically removed epileptogenic zone from patients with focal drug‐resistant epilepsy: From operating room to wet lab

open access: yesEpilepsia Open, EarlyView.
Abstract Objective We have established a comprehensive sample handling protocol designed for the multiscale assessment of epileptogenic tissue. This protocol aims to identify novel therapeutic targets and enhance the diagnosis and stratification of patients with drug‐resistant epilepsy, thereby optimizing their treatment with anti‐seizure medications ...

Clock gene dysregulation in epilepsy: A systematic review

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Epileptic seizures show a rhythmic pattern, being more frequent at particular times of the day (e.g., only occurring during sleep), suggesting a role of the circadian rhythm. Clock genes regulate the circadian rhythm and might be involved in the pathophysiology of epilepsy.
