Synopsis
The term “muscular dystrophy” (MD) describes a group of primary genetic disorders of muscle that often have a distinctive and recognizable clinical p- notype, accompanied by characteristic, but frequently not pathognomonic, pathological features. Research into the molecular basis of the MDs by a c- bination of positional cloning and candidate gene analysis has provided the basis for a reclassification of these disorders, with genetic and protein data augmenting traditional clinically based nomenclature. These findings have brought insights into the molecular pathogenesis of MD, with an increasing number of potential pathways involved in arriving at a dystrophic phenotype. Some common themes can be recognized, however, including the involvement of five members of the dystrophin-associated complex (dystrophin and four sarcoglycans) in different types of MD, and the involvement of two nuclear envelope proteins in producing an Emery-Dreifuss MD phenotype. Other d- ease-associated genes appear to cause MD in a completely unrelated way, such as the involvement of calpain 3 in a form of limb-girdle muscular dystrophy. Section 1 of Muscular Dystrophy: Methods and Protocols reviews tra- tional strategies used to identify MDs. Meantime, techniques developed as a result of the research strategies described previously have become an integral part of the management of many patients with MD and their families, and these techniques are addressed in Sections 2 (DNA-based tests) and 3 (p- tein-based analyses). The continued effort to translate this enhanced und- standing into a molecular cure or treatment for MD is reviewed in Section 4.
From the Back Cover
With the molecular mechanisms underlying the various forms of muscular dystrophy now rapidly clarifying, precise diagnosis has become a reality, and even a requirement in clinical practice. In Muscular Dystrophy: Methods and Protocols, Katherine Bushby and Louise Anderson have assembled an outstanding collection of key techniques for the analysis of DNA and protein from patients suspected to suffer from muscular dystrophy. Each method is highly detailed to ensure success and is presented by a hands-on expert who uses it on a day-to-day basis. The various DNA techniques focus on both the X-linked muscular dystrophies and the autosomal recessive muscular dystrophies. The protein methods include expression analysis, multiplex western blot analysis, immunocytochemical analysis, and reviews of immunological reagants and of amplification systems. Also discussed are the use of animal models to understand human muscular dystrophy and the available options for gene-based therapy.
Comprehensive and highly practical, Muscular Dystrophy: Methods and Protocols offers today‚s diagnostic laboratories, basic and medical researchers, and active clinicians an authoritative collection of tools that will serve as exacting diagnostic tools as well as greatly empowering research on the novel therapeutics now beginning to emerge.
