Research
Studies & key findings
- SS-31 selectively binds cardiolipin on the inner mitochondrial membrane, stabilizing cristae architecture and electron transport chain supercomplexes; PNAS proteomics identified 12 direct SS-31 interactors — all cardiolipin-binding proteins involved in OXPHOS and 2-oxoglutarate metabolism.
- Ex vivo treatment of explanted failing human hearts acutely improved mitochondrial respiration and supercomplex function, demonstrating the mechanism is independent of long-term cardiolipin remodeling (JACC: Basic to Translational Science, 2019).
