The cellular prion protein (PrP(C)) has been implicated with the modulation of neuronal apoptosis, adhesion, neurite outgrowth and maintenance which are processes involved in the neocortical development. Malformations of cortical development (MCD) are frequently associated with neurological conditions including mental retardation, autism, and epilepsy. Here we investigated the behavioral performance of female adult PrP(C)-null mice (Prnp(0/0)) and their wild-type controls (Prnp(+/+)) presenting unilateral polymicrogyria, a MCD experimentally induced by neonatal freeze-lesion in the right hemisphere. Injured mice from both genotypes presented similar locomotor activity but Prnp(0/0) mice showed a tendency to increase anxiety-related responses when compared to Prnp(+/+) animals. Additionally, injured Prnp(0/0) mice have a poorer performance in the social recognition task than sham-operated and Prnp(+/+) injured ones. Moreover the step-down inhibitory avoidance task was not affected by the procedure or the genotype of the animals. These data suggest that the genetic deletion of PrP(C) confers increased susceptibility to short-term social memory deficits induced by neonatal freezing model of polymicrogyria in mice.

Recent years have seen enormous progress in the field of advanced therapeutics for the progressive muscle wasting disease Duchenne muscular dystrophy (DMD). In particular, four antisense oligonucleotide (ASO) therapies targeting various DMD-causing mutations have achieved FDA approval, marking major milestones in the treatment of this disease. These compounds are designed to induce alternative splicing events that restore the translation reading frame of the dystrophin gene, leading to the generation of internally-deleted, but mostly functional, pseudodystrophin proteins with the potential to compensate for the genetic loss of dystrophin.

Forward genetic screens of mutant populations are fundamental for functional genomics studies. However, isolating independent mutant alleles to molecularly identify causal genes is challenging in species recalcitrant to genetic manipulation. Here, we demonstrate that classic seed EMS mutagenesis coupled with genome sequencing can overcome this limitation in sorghum.

Unlabelled: Coronaviruses have large, positive-sense single-stranded RNA genomes that challenge conventional strategies for mutagenesis. Yeast genetics has been used to manipulate large viral genomes, including those of herpesviruses and coronaviruses. This method, known as transformation-associated recombination (TAR), involves assembling complete viral genomes from dsDNA copies of viral genome fragments via homologous recombination in .

Pullorum, the causative agent of pullorum disease, posing a significant threat to the global production of poultry meat and eggs. However, existing detection methods have substantial limitations in efficiency and accuracy. Herein, we developed a genomic deletion-targeted TaqMan qPCR assay for identification of Pullorum, enabling precise differentiation from other serovars.

Polyhydroxyalkanoates (PHA) are bioplastics produced by few bacteria as intracellular lipid inclusions under excess carbon source and nutrient-deprived conditions. These polymers are biodegradable and resemble petroleum-based plastics. The rising environmental concerns have increased the demand for PHA, but the low yield in wild-type bacterial strains limits large-scale production.
