Function 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...

متن کاملThe Caenorhabditis elegans septin complex is nonpolar.
Septins are conserved GTPases that form heteromultimeric complexes and assemble into filaments that play a critical role in cell division and polarity. Results from budding and fission yeast indicate that septin complexes form around a tetrameric core. However, the molecular structure of the core and its influence on the polarity of septin complexes and filaments is poorly defined. The septin c...
متن کاملMitochondrial complex I is deficient in renal oncocytomas.
Renal oncocytomas are benign tumors characterized by dense accumulation of mitochondria the cause of which remains unknown so far. Consistently, mitochondrial DNA content and the amounts and catalytic activities of several oxidative phosphorylation (OXPHOS) complexes were known to be increased in these tumors, but it was not ascertained that the OXPHOS system was functional. Here we investigate...
متن کاملTransition–defective Mutants in Caenorhabditis elegans
The metaphase to anaphase transition is a critical stage of the eukaryotic cell cycle, and, thus, it is highly regulated. Errors during this transition can lead to chromosome segregation defects and death of the organism. In genetic screens for temperature-sensitive maternal effect embryonic lethal (Mel) mutants, we have identified 32 mutants in the nematode Caenorhabditis elegans in which fert...
