Web10 jul. 2024 · Indeed, the results revealed that when mitoflash frequency decreased, the ATP concentration or set-point increased. This suggests that mitoflash activity may act as an ATP set-point regulator that responds to changes in energy supply and demand in order to maintain ATP homeostasis in the heart (see Figure 6 in Wang et al., 2024).

Here, we investigated mitoflash activities, using the different combinations of ETC substrates and … Web7 feb. 2024 · In this study, we sought to clarify the mechanism of mitoflash generation by tracking the transfer of protons across the IMM. Using different fluorescent pH sensors targeted to mitochondrial compartments, we consistently observed matrix alkalinization transients, establishing the pH nature of the flashes, which we renamed “mitopHlashes”.
