Animal disease; Duchenne muscular dystrophy; Model; Phenotype

Duchenne muscular dystrophy (DMD) is a human disease characterized by progressive and irreversible skeletal muscle degeneration caused by mutations in genes coding for important muscle proteins. Unfortunately, there is no efficient treatment for this disease; it causes progressive loss of motor and muscular ability until death. The canine model (golden retriever muscular dystrophy) is similar ... more

Becker muscular dystrophy; deletions/duplications; Duchenne muscular dystrophy; Multiplex ligation-dependent probe amplification

Deletions/duplications in the Duchenne muscular dystrophy (DMD) gene account for 60 to 70% of all alterations. A new technique, multiplex ligation-dependent probe amplification (MLPA), has been described that allows the detection of large genetic rearrangements by simultaneous amplification of up to 45 target sequences. The present article is based on the diagnosis of the first Argentine ... more

Duchenne muscular dystrophy; Dystrophin gene; Han population genetics; Microsatellite; Polymorphism

To look for novel microsatellites in the dystrophin gene for the diagnosis of Duchenne muscular dystrophy, candidate microsatellite sites in the dystrophin gene were analyzed with the SSRHunter software and were also genotyped. Among the 15 candidate microsatellite sites, three novel microsatellite sites in the 60th, 30th, and 2nd intron were found to have a high degree of polymorphism. ... more

Differential expression; Duchenne muscular dystrophy; Protein-protein interaction network

Duchenne muscular dystrophy (DMD), which is caused by mutations in the X-linked dystrophin gene, is a severe and progressive neuromuscular disease with no available cure. By integrating 2 microarray datasets from the Gene Expression Omnibus, we identified differentially expressed genes in 2 stages of DMD and systematically explored their potential disease-related mechanisms using a ... more

Differentially expressed gene; Disc degeneration; Dysfunctional pathway

Disc degeneration is strongly associated with back or neck pain, sciatica, and disc herniation or prolapse. It places an enormous economic burden on society and can greatly affect quality of life. Alternative treatment approaches, such as genetic therapies, are urgently needed to slow or reverse the disc degeneration process. We downloaded gene expression data from Gene Expression Omnibus ... more

B cell chronic lymphocytic leukemia; Disease progression; VEGF polymorphism

We investigated the relationship between a VEGF genetic polymorphism and B cell chronic lymphocytic leukemia (B-CLL). A total of 102 patients with B-CLL and 124 healthy subjects were included in this study. All individuals were typed for the rs10434 in the vascular endothelial growth factor (VEGF) gene using the TaqMan technique. We found that the A allele and the AA genotype of ... more
