What is the molecular mechanism underlying cardiomyopathy in Duchenne muscular dystrophy?5 answersThe molecular mechanisms contributing to cardiomyopathy in Duchenne muscular dystrophy (DMD) involve various factors. The absence of dystrophin leads to disruption of the dystrophin-associated protein complex (DAPC), affecting proteins like neuronal nitric oxide synthase (nNOS). This disruption can result in calcium mishandling and overload in cardiac myocytes, leading to muscle cell death and diminished contractile function. Additionally, DMD cardiomyocytes (DMD-CMs) exhibit altered ion channel expression, including potassium and calcium handling proteins, contributing to calcium transient abnormalities and hypocontractility. Furthermore, DMD-iCMs secrete exosomes containing altered microRNA profiles, such as upregulation of miR-339-5p, which modulates stress-responsive genes and impairs cellular stress response, potentially exacerbating cardiomyopathy in DMD. These findings collectively highlight the multifaceted molecular mechanisms involved in the development of cardiomyopathy in DMD.

Dopeople with mitochondrial dysfunction cause accelerated ageing5 answersMitochondrial dysfunction is closely linked to accelerated aging. Dysfunctional mitochondria in T cells have been shown to induce multimorbidity and premature senescence. In MDPL Syndrome, a genetic premature aging disease, mitochondrial dysfunction is a hallmark, leading to impaired mitochondrial biogenesis and activity. Mitochondrial dysfunction, characterized by decreased respiratory capacity, membrane potential, and increased production of reactive oxygen species (ROS), is both a cause and consequence of cellular senescence. Age-related mitochondrial dysfunction also contributes to the development of type 2 diabetes mellitus (T2D) by impairing ATP production and glucose oxidation. Mitochondrial uncoupling proteins (UCPs) play a protective role against age-related oxidative stress in T2D. Severe mitochondrial dysfunction can lead to a range of diseases and accelerate the aging process.
