Mitochondrial membrane potential: a trait involved in organelle inheritance?
Which mitochondria are inherited across generations? Are transmitted mitochondria functionally silenced to preserve the integrity of their genetic information, or rather are those mitochondria with the highest levels of function (as indicated by membrane potential Δψm) preferentially transmitted? Based on observations of the unusual system of doubly uniparental inheritance of mitochondria and o...
متن کاملOrganelle Inheritance
The need to inherit those membranes that arise from the ER is much less clear. As an example, the integral *Imperial Cancer Research Fund Cell Biology Laboratory membrane proteins and lipids of the Golgi apparatus are derived entirely from the ER. If a daughter did not 44 Lincoln's Inn Fields London WC2A 3PX inherit a copy of the Golgi apparatus, it should be able to synthesize one de novo. Sev...
متن کاملRat liver GTP-binding proteins mediate changes in mitochondrial membrane potential and organelle fusion.
The variety of mitochondrial morphology in healthy and diseased cells can be explained by regulated mitochondrial fusion. Previously, a mitochondrial outer membrane fraction containing fusogenic, aluminum fluoride (AlF4)-sensitive GTP-binding proteins (mtg) was separated from rat liver (J. D. Cortese, Exp. Cell Res. 240: 122-133, 1998). Quantitative confocal microscopy now reveals that mtg tran...
متن کاملUniparental inheritance of organelle genes
the remarkable and varied molecular and cellular mechanisms that produce these patterns. I will also consider the evolutionary consequences of uniparental inheritance and some of the proposed evolutionary explanations for this remarkable difference between the inheritance of organelle and nuclear genes. Patterns and mechanisms of uniparental inheritance vary widely Correns studied the four-o'cl...
متن کاملThe effect of aminoguanidine on sperm motility and mitochondrial membrane potential in varicocelized rats
Objective(s): Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial membrane potential (MMP) in varicoceli...
