Summary
Autosomal dominant centronuclear myopathy (AD-CNM) is a rare genetic muscle disorder caused by DNM2 gene mutations. Research is exploring new therapies targeting DNM2 expression for clinical trials.
Area of Science:
- Genetics and Molecular Biology
- Neuromuscular Disorders
Context:
- Autosomal dominant centronuclear myopathy (AD-CNM) is a rare congenital myopathy.
- It is characterized by muscle weakness and centrally located nuclei in muscle fibers.
- AD-CNM is caused by mutations in the DNM2 gene, encoding dynamin 2 (DNM2).
Purpose:
- To review the pathophysiology of AD-CNM.
- To highlight the clinical and histopathological features of AD-CNM.
- To discuss emerging therapeutic strategies for AD-CNM.
Summary:
- DNM2 mutations lead to a spectrum of AD-CNM, affecting muscle homeostasis through various mechanisms.
- Pathophysiological defects include issues with excitation-contraction coupling, muscle regeneration, mitochondria, and autophagy.
- Histopathological hallmarks include nuclear centralization and type 1 myofiber abnormalities.
Impact:
- Understanding AD-CNM mechanisms informs the development of targeted therapies.
- Therapeutic approaches include modulating DNM2 expression or allele-specific silencing.
- These strategies pave the way for clinical trials in AD-CNM patients.

2.0K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

11
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

15
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

14
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
