mPTP opening has been implicated as the determinant cell death pathway in cancer.32, 40, 41 It has been previously reported that the location of IR‐783 was almost completely congruent with MitoTracker (a mitochondrial‐selective probe) in prostate cancer cells, and the cancer‐specific uptake of these organic dyes occurs primarily via OATP1B3. This evidence concerns the gene SLCO1B3 and cancer.
