    Neurons derived from transplanted neural stem cells restore disrupted neuronal circuitry in a mouse model of spinal cord injury

    The body's capacity to restore damaged neural networks in the injured CNS is severely limited. Although various treatment regimens can partially alleviate spinal cord injury (SCI), the mechanisms responsible for symptomatic improvement remain elusive. Here, using a mouse model of SCI, we have shown that transplantation of neural stem cells (NSCs) together with administration of valproic acid (VPA), a known antiepileptic and histone deacetylase inhibitor, dramatically enhanced the restoration of hind limb function. VPA treatment promoted the differentiation of transplanted NSCs into neurons rather than glial cells. Transsynaptic anterograde corticospinal tract tracing revealed that transplant-derived neurons reconstructed broken neuronal circuits, and electron microscopic analysis revealed that the transplant-derived neurons both received and sent synaptic connections to endogenous neurons. Ablation of the transplanted cells abolished the recovery of hind limb motor function, confirming that NSC transplantation directly contributed to restored motor function. These findings raise the possibility that epigenetic status in transplanted NSCs can be manipulated to provide effective treatment for SCI.journal articl

    A de novo nonsense variant in the DMD gene associated with X‐linked dystrophin‐deficient muscular dystrophy in a cat

    Abstract Background X‐linked dystrophin‐deficient muscular dystrophy (MD) is a form of MD caused by variants in the DMD gene. It is a fatal disease characterized by progressive weakness and degeneration of skeletal muscles. Hypothesis/Objectives Identify deleterious genetic variants in DMD by whole‐genome sequencing (WGS) using a next‐generation sequencer. Animals One MD‐affected cat, its parents, and 354 cats from a breeding colony. Methods We compared the WGS data of the affected cat with data available in the National Center for Biotechnology Information database and searched for candidate high‐impact variants by in silico analyses. Next, we confirmed the candidate variants by Sanger sequencing using samples from the parents and cats from the breeding colony. We used 2 genome assemblies, the standard felCat9 (from an Abyssinian cat) and the novel AnAms1.0 (from an American Shorthair cat), to evaluate genome assembly differences. Results We found 2 novel high‐impact variants: a 1‐bp deletion in felCat9 and an identical nonsense variant in felCat9 and AnAms1.0. Whole genome and Sanger sequencing validation showed that the deletion in felCat9 was a false positive because of misassembly. Among the 357 cats, the nonsense variant was only found in the affected cat, which indicated it was a de novo variant. Conclusion and Clinical Importance We identified a de novo variant in the affected cat and next‐generation sequencing‐based genotyping of the whole DMD gene was determined to be necessary for affected cats because the parents of the affected cat did not have the risk variant

In exon organization, the boxes represent exons. The bars indicate regions amplified in the PCR analysis and used as probes in the Northern blot analysis. Coding regions were determined by selecting the longest open reading frames deduced from cDNA sequences. The predicted coding regions are shaded. The position of the poly A signal is marked by filled arrowheads, and the presence of poly A is indicated by 'A'. Chromosomal location was determined by searching the mouse and human genome databases. The predicted amino acid sequences of genes were analyzed using various bioinformatics tools (see Experimental Procedure). For annotation of genes with ontology terms, amino acid sequences were submitted to and subsequently obtained from exclusive web servers (Goblet), which use a variety of different protein databases and provide gene ontology codes. Each gene ontology code falls into one of the larger categories of molecular function (M), cellular component (C), or biological process (B)
