Furthermore, processed OPA1 was observed in heart tissue derived from heart-specific TFAM knock-out mice suffering from mitochondrial cardiomyopathy and in skeletal muscles from patients suffering from mitochondrial myopathies such as myopathy encephalopathy lactic acidosis and stroke-like episodes.
Abolished mtDNA transcription caused by tissue-specific knockout of TFAM in the mouse heart leads to early onset of a severe mitochondrial cardiomyopathy with lethality within the first post-natal weeks.
AARS2 gene (NM_020745.3) mutations result in two different phenotypic diseases: infantile mitochondrial cardiomyopathy and late-onset leukoencephalopathy.
An autosomal recessive mutation in this gene has been linked to AARS2 mutation-related adult-onset leukodystrophy (AARS2-L) or infantile mitochondrial cardiomyopathy.
Furthermore, processed OPA1 was observed in heart tissue derived from heart-specific TFAM knock-out mice suffering from mitochondrial cardiomyopathy and in skeletal muscles from patients suffering from mitochondrial myopathies such as myopathy encephalopathy lactic acidosis and stroke-like episodes.
Surprisingly, we demonstrate that a strong mitochondrial cardiomyopathy and diminished respiration due to DARS2 deficiency can be alleviated by the loss of CLPP, leading to an increased de novo synthesis of individual OXPHOS subunits.
First description of a novel mitochondrial mutation in the MT-TI gene associated with multiple mitochondrial DNA deletion and depletion in family with severe dilated mitochondrial cardiomyopathy.
Extensive fragmentation of mtDNA was detected in association with increased 8-hydroxydeoxyguanosine content in the heart mitochondrial DNA (mtDNA) from a patient with premature aging and mitochondrial cardiomyopathy, who carried a mutation within the mitochondrial tRNA(Asp) gene.
These observations were more prominent than in other patients with heart failure of different etiology, which suggests that the increased ROS generation and anti-oxidative response were involved in the development of the mitochondrial cardiomyopathy.
Extensive fragmentation of mtDNA was detected in association with increased 8-hydroxydeoxyguanosine content in the heart mitochondrial DNA (mtDNA) from a patient with premature aging and mitochondrial cardiomyopathy, who carried a mutation within the mitochondrial tRNA(Asp) gene.
