    Species differences in mitochondrial apoptosis control can bias cytotoxicity interpretation in preclinical test systems.

  • 2

    Bovine cells exhibit human-like regulation of BAX/BAK localization and responses to cytotoxic agents, unlike murine systems.

  • 3

    BAX/BAK localization was quantified across species, revealing bovine cells closely match human patterns.

  • 4

    Bovine BAX is more similar to human BAX than murine BAX at the amino acid level, differing by only 2.6%.

  • 5

    Species-dependent OMM assembly states of BAX/BAK influence the reporting of intrinsic-apoptosis endpoints.
