Summary: DMD is a devastating X-linked disease characterized by progressive skeletal muscle wasting and heart dysfunction. Therapeutic strategies involving epigenetic modifications to modulate signal pathways have emerged as promising approaches. Taking a systemic view of DMD as a disease affecting muscle fibers and communication between different cell types may lead to holistic treatments that restore proper signal transmission and gene expression.

Summary: This study found that long noncoding RNAs play important roles in Duchenne and Becker muscular dystrophy, particularly in regulating myocyte proliferation and differentiation with potential therapeutic implications. The research suggests that lncRNA44s2 may serve as an accelerator in muscle differentiation process and is associated with a favorable clinical phenotype.

Summary: This systematic review examines the use of tamoxifen in the treatment of Duchenne Muscular Dystrophy (DMD). The review found promising outcomes in terms of muscular strength recovery and a decrease in pathology biomarkers. However, more research is needed to determine the definitive beneficial effects of tamoxifen on quality-of-life and survival, particularly in young patients.

Summary: This study investigated the transcription dynamics and spatial localization of the dystrophin (DMD) gene in DMD patients. The results showed significantly reduced DMD mRNA amount in the patients' cells and muscle biopsies, with a shift towards localization in the nuclei. This abnormal compartmentalization of mutant DMD mRNA contributes to the poor abundance and availability of dystrophin messenger in the cytoplasm.

Summary: The neuropsychological profile of Indian DMD subjects is not well understood and requires evaluation. Results show poor verbal and visual memory profiles in DMD patients, with working memory deficits being a crucial element of cognitive functioning. Working memory interventions may help improve neuropsychological profiles in DMD cases.

Summary: The study identified the CXCL12-CXCR4 pathway as a potential target for treating Duchenne muscular dystrophy, as this pathway showed increased expression in DMD patients and mdx mice, and significantly decreased after steroid treatment.

Summary: Mutations in the DMD gene cause Duchenne muscular dystrophy (DMD), but recent research shows that reduced DMD expression is also associated with various malignancies. The downregulation of DMD in tumors is correlated with reduced patient survival and tumor stage. These findings challenge the current understanding of dystrophin expression and suggest a broader significance of the DMD gene beyond DMD.

Summary: The study found that fenofibrate can promote the differentiation of myofibers by down-regulating the expression of myostatin protein in myoblasts, significantly improving muscle function and reducing muscle damage in mdx mice, along with anti-inflammatory effects.

Summary: Duchenne muscular dystrophy (DMD) is a severe neuromuscular disorder caused by mutations in the dystrophin gene. Lack of functional dystrophin protein leads to fragile muscle membranes and increased susceptibility to damage during contraction. Inflammation plays a crucial role in exacerbating muscle damage and impairing regeneration in DMD patients, with neutrophils releasing inflammatory compounds that prolong the inflammatory response.

Summary: Dystrophinopathy is a disease caused by alterations in the DMD gene. In this study, a combined laboratory and computational analysis approach was used to identify disease-causing genomic variants and regulatory mechanisms underlying abnormal DMD transcript generation in genetically undiagnosed patients. Abnormal DMD transcripts were detected in the majority of cases, with exonization of intronic sequences, exon skipping, aberrant splicing, polyadenylation, and transcription termination identified as the underlying mechanisms. The findings of this study have important implications for therapeutic options for patients with Dystrophinopathy.

Summary: This study systematically assessed cardiac lesions in carrier dogs, GRMD dogs, and normal dogs, and found that quantitative analysis of the cross-sectional area of fibrosis can distinguish the health status of different groups of dogs. The features identified in GRMD dogs are compatible with those of DMD, validating GRMD as an effective model for studying cardiomyopathy.

Summary: Mutation of the DMD gene causes muscular dystrophies, but it is also implicated in the development of major cancer types. Disruption of the balance of DMD gene products in cancer may play a key role in tumorigenesis. Further study into the potential role of DMD gene products in cancer is needed to develop new therapeutics.
