VDAC1 and cancer: Reversely, they were usually aggregated as oligomers in cancer, inflammatory and apoptosis‐related diseases.[27a] The oligomers of VDAC1 significantly enhanced the transporting ability and further affected mitochondrial metabolism.[27] In our study, Cd exposure mainly induced VDAC1 dimerization like that found in other experimental models with As2O3, H2O2, cisplatin or selenite treatment.[18] It indicates that dimerization is a dominating, easy‐forming and more stable state compared to other VDAC1 aggregates (e.g., trimer, tetramer) in pathological conditions.
