Abstract:
JOURNAL/nrgr/04.03/01300535-202604000-00045/figure1/v/2025-06-30T060627Z/r/image-tiff Ischemia-reperfusion injury is a common pathophysiological mechanism in retinal degeneration. PANoptosis is a newly defined integral form of regulated cell death that combines the key features of pyroptosis, apoptosis, and necroptosis. Oligomerization of mitochondrial voltage-dependent anion channel 1 is an important pathological event in regulating cell death in retinal ischemia-reperfusion injury. However, its role in PANoptosis remains largely unknown. In this study, we demonstrated that voltage-dependent anion channel 1 oligomerization-mediated mitochondrial dysfunction was associated with PANoptosis in retinal ischemia-reperfusion injury. Inhibition of voltage-dependent anion channel 1 oligomerization suppressed mitochondrial dysfunction and PANoptosis in retinal cells subjected to ischemia-reperfusion injury. Mechanistically, mitochondria-derived reactive oxygen species played a central role in the voltage-dependent anion channel 1-mediated regulation of PANoptosis by promoting PANoptosome assembly. Moreover, inhibiting voltage-dependent anion channel 1 oligomerization protected against PANoptosis in the retinas of rats subjected to ischemia-reperfusion injury. Overall, our findings reveal the critical role of voltage-dependent anion channel 1 oligomerization in regulating PANoptosis in retinal ischemia-reperfusion injury, highlighting voltage-dependent anion channel 1 as a promising therapeutic target.

Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several...
