Muscular Dystrophy Research

While there is no known cure, scientists are certain of the genetic make-up that causes muscular dystrophy, an inherited faulty gene. This gene can be inherited in one of four ways: X-linked or sex-linked recessive, when a man with X-Linked muscular dystrophy has children, Autosomal Recessive Inheritance, and Autosomal Dominant Inheritance.

According to the " Muscle Diseases" by Patrick F.Chinnery in the Goldman's Cecil Medicine, 24th Ed 2012, "Duchenne Muscular Dystrophy affects about 1 in 3500 males. About one third of the cases arises from a de novo mutation without a family history."

Duchenne Muscular Dystrophy is a disease which causes skeletal muscle to waste away, this wasting of muscle is caused by a mutation of the dystrophin gene (Meregalli et al., 2013, p. 4251).

Occurrence of muscle dystrophy is estimated to be one in 3-4,000 male births. There are also about 15,000 muscular dystrophy patients in the United States today with this disease. Those who have muscular dystrophy are missing the protein called dystrophin. Before scientists ever discovered the missing protein, the tested carriers for the disease had a high presence of elevated serum levels of creatine and phosphokinase. The disease can now be found for a prenatal diagnosis.

Duchenne Muscular Dystrophy is a genetic disorder that is passed on through the x chromosomes. Only men are

Duchenne muscular dystrophy is a gender-linked inherited disorder. To illustrate, males only have one X chromosome, therefore they do not have a second X chromosome to make up for the damaged gene. Females can only become carriers of the disease, as females have a second X chromosomes to make up for the damaged gene.

Ben has Duchenne Muscular Dystrophy (DMD). DMD is a degenerative disease of the muscles. When someone has this disease their muscles do not produce enough dystrophin to stay together. This causes the muscles to deteriorate over time. With proper care, the rate of muscle degradation can be slowed down. Duchenne muscular dystrophy is a genetic disorder characterized by progressive muscle degeneration and weakness. Muscle weakness can start as early as age three. It first affects the hips, pelvic area, thighs, and shoulders. This disease is still fatal and will be until further studies and research are done to find ways to cure this disease.

The use of creditable and appropriate resources is important for educators because all internet should be adept at critically evaluating information (Rankin, Stallings & London, 2005, p.380). To ensure that information is unbiased, accurate, and up to date and clear to the reader the educator should evaluate each resource that is going to be used (Rankin, et al., 2005, p. 280). Muscular dystrophy is a group of diseases that cause progressive weakness and loss of muscle mass (Muscular Dystrophy Canada, 2015). The Muscular Dystrophy Canada has developed a web page available for those effected by muscular dystrophy and their caregivers. It is located at the web address www.muscle.ca.

Prior to the 1980s, there was minimum knowledge relating to the causes of muscular dystrophy. However, in 1986, researchers discovered a gene, soon to be named dystrophin, on the X chromosome. The gene, when mutated, reacted by causing Duchenne muscular dystrophies. During 1987, the protein in relation to the gene discovered a year early was officially classified and named dystrophin. Duchenne Muscular Dystrophy (DMD) develops due to the mutated gene failure to supply active dystrophin. This minimum amount of dystrophin affects the body by developing muscle damage and continued weakness from early life.

DMD is caused by a mutation in the X-linked dystrophin gene, which results in a dysfunctional dystrophin protein. Dystrophin is a cytoskeletal protein that provides mechanical stability to muscle cells by connecting the muscle sarcolemma to the basal lamina of the extracellular matrix (ECM), and without it there, the muscle cells typically undergo a process of degeneration and regeneration. This process is limited by the survival of satellite cells present since satellite cells can only undergo mitosis a limited amount of times. Sarcolemma instability typically results in excess intracellular amounts of both sodium and calcium, which causes ATP depletion and mitochondrial uncoupling (Horn & Schleip, 2012). Satellite cells only have a limited number times they can undergo mitosis, and once a patient can no longer generate healthy muscle cells, the patient will typically experience cell death. This cell death and necrosis usually

Duchenne muscular dystrophy (DMD) is caused by a mutated gene in the X chromosome. This flawed genes is passed on by the mother. However, most carrier of the gene do not show signs or symptoms of the disease. The The flawed gene causes the improper production of the protein dystrophin which is accompanied by “defective dystrophin-glycoprotein complex (DGC) in the sarcolemma and leads to progressive muscle degeneration” (Nakamura & Takeda, 2011). The Dystrophin protein is vital in providing a muscle integrity. Therefore, the absence of dystrophin production can lead to muscled atrophy.

In Duchenne Muscular Dystrophy, the protein dystrophin has no function at all. Due to the fact that the protein has always been enabled, it causes the symptoms and diagnosis for Duchenne Muscular Dystrophy to be so severe and worsen quicker (Bushby pp.1). This is harmful because their muscles have no protection. The cells that make up the muscles require this protein to become strong and healthy. In comparison, Becker Muscular Dystrophy has the dystrophin protein who mildly functions. (B 2015 MDA). Since it makes a shortened form of the dystrophin they have much more protection of their muscles compared to a patient who has Duchenne Muscular Dystrophy. Resulting that Becker Muscular Dystrophy is not as severe as having Duchenne Muscular

Therefore, I'm gonna talk about the causes, the common types and the treatments for the Muscular Dystrophy.

Duchenne Muscular Dystrophy or DMD for short is a genetic disease that affects the skeletal muscles causing muscle degeneration and muscle wasting. Duchenne Muscular Dystrophy is an X-linked recessive chromosomal disease, which is caused by mutations in the DMD Gene (Regenerative Medicine). This Disease affects 1 in 3600 boys (Regenerative Medicine). A male born with this disease experiences respiratory dysfunction, trouble ambulation, cognitive impairment, some even experience premature death. Unfortunately, there is no cure for DMD, but there are research studies in the works for different therapies to help reverse this gene mutation and to elevate symptoms associate with this disease.

Duchenne’s Muscular Dystrophy is a recessive muscle disorder that will affect 1 in 3500 newborn boys. Early death is caused by progressive muscle wasting. The disease is caused by mutations in the dystrophin gene. Mutations in the dystrophin gene can occur, but the life span is normally longer in patients. In this journal the research was too administer injections of PRO051 for 5 weeks in 12 different patients and monitor changes in their RNA splicing and protein levels in the tibialis anterior muscle. 12 patients each performed a 6 minute walk a total of 3 different times to measure the affects that PRO051 had on the muscle fibers. The study concluded that the use of PRO051 in patients suffering from Duchenne’s Muscular Dystrophy had a modest
