Disrupting Mitochondrial–Nuclear Coevolution Affects OXPHOS Complex I Integrity and Impacts Human Health
The mutation rate of the mitochondrial DNA (mtDNA), which is higher by an order of magnitude as compared with the nuclear genome, enforces tight mitonuclear coevolution to maintain mitochondrial activities. Interruption of such coevolution plays a role in interpopulation hybrid breakdown, speciation events, and disease susceptibility. Previously, we found an elevated amino acid replacement rate...
متن کاملDifferences in assembly or stability of complex I and other mitochondrial OXPHOS complexes in inherited complex I deficiency.
NADH-ubiquinone oxidoreductase (complex I) deficiency is amongst the most encountered defects of the mitochondrial oxidative phosphorylation (OXPHOS) system and is associated with a wide variety of clinical signs and symptoms. Mutations in complex I nuclear structural genes are the most common cause of isolated complex I enzyme deficiencies. The cell biological consequences of such mutations ar...
متن کاملImpaired OXPHOS Complex III in Breast Cancer
We measured the mitochondrial oxidative phosphorylation (mtOXPHOS) activities of all five complexes and determined the activity and gene expression in detail of the Complex III subunits in human breast cancer cell lines and primary tumors. Our analysis revealed dramatic differences in activity of complex III between normal and aggressive metastatic breast cancer cell lines. Determination of Com...
متن کاملFunction of mitochondrial complex-I and -IV in normal human and Parkinson's disease cybrids
Mitochondrial dysfunction has been implicated in the dopaminergic neurodegeneration, which characterizes Parkinson’s disease (PD). The activities of mitochondrial complexes I and IV were found to be reduced in the brains of PD patients (n = 4) as compared to age-matched controls (n = 4). This is tested in SH-SY5Y cell lines, transformed Rho0 cells, and in normal and PD cybrid cell lines. Cybrid...
