When mammalian mitochondria are exposed to high calcium and phosphate, a massive swelling, uncoupling of respiration, and release of cytochrome c occur. These changes are mediated by opening of the mitochondrial permeability transition pore (MPTP). Activation of the MPTP in vivo in response to hypoxic and oxidative stress leads to necrotic and apoptotic cell death. Considering that embryos of the brine shrimp Artemia franciscana tolerate anoxia for years, we investigated the MPTP in this…

The results of this study demonstrate that shrimp mitochondria take up large quantities of calcium through a canonical mitochondrial calcium uniporter, and neither calcium nor other ions were observed to promote permeability transition.

The present work is the first report of the presence of a voltage‐ and Ca2+‐dependent MPTP in gametes of invertebrates and indicates MPTP opening as another evolutionary feature shared by sea urchins and mammals.
On the Mechanism(s) of Membrane Permeability Transition in Liver Mitochondria of Lamprey, Lampetra fluviatilis L.: Insights from Cadmium
- BiologyBioMed research international

Under monitoring of the transmembrane potential of the “spring” lamprey liver mitochondria, it is revealed that Cd2+ produced its decrease on both types of the respiratory substrates used that was strongly hampered by cyclosporine A, and the membrane potential was partially restored by dithiothreitol.

Embryos of the brine shrimp, Artemia franciscana, survive extended periods of anoxia and diapause, and evidence indicates that opening of the mitochondrial permeability transition pore and release of cytochrome c (cyt-c) do not occur, and caspase activation in this crustacean is not dependent on cyt-c.

The presence of two alternative redox enzymes in the respiratory chain of A. franciscana nauplii and the white shrimp indicates different adaptive mechanisms from artemia to face environmental challenges related to the changing levels of oxygen concentration in seawater through their life cycles.
Absence of Ca2+-Induced Mitochondrial Permeability Transition but Presence of Bongkrekate-Sensitive Nucleotide Exchange in C. crangon and P. serratus

The findings suggest that the ability to undergo Ca2+-induced mitochondrial permeability transition and the sensitivity of adenine nucleotide translocase to bongkrekate are not necessarily related phenomena.

C coupled mitochondria of the yeast Endomyces magnusii were examined for the presence of a Ca2+- and phosphate-induced permeability of the inner mitochondrial membrane (pore) and it was evident that E. magnusII mitochondria lack a functional Ca2-dependent pore, or possess a pore differently regulated as compared to that of mammalian mitochondria.

The evidence in favour of the model for the molecular mechanism of the mitochondrial permeability transition is summarized and it is demonstrated directly that mPT pores open during reperfusion (but not ischaemia) using a technique that involves entrapment of [3H]deoxyglucose in mitochondria that have undergone the mPT.

Yeast mitochondria (Saccharomyces cerevisiae) contain a permeability transition pore which is regulated differently than the pore in mammalian mitochondria, and this suggests that the same pore is induced in both cases and is comparable in size with the permeability Transition pore of heart and liver mitochondria.
