Figure Lengend Snippet: Cu-dependent activation of CuCOX promotes oxygen consumption, reorganization of respiratory supercomplexes, and nucleotide biosynthesis essential for Cu-dependent tumor growth. A–D, OCR from representative Seahorse mitochondrial stress tests in 786-O ( A and B ) and RCC4 ( C and D ) cells. Quantification of basal respiration, maximal respiration (post-FCCP injection), and respiration coupled to ATP production. P value from paired t test. E, Blue NativePAGE (BN-PAGE) analysis of respiratory complexes using digitonin permeabilized mitochondria isolated by anti-TOM22 immunopurification from Cu Hi vs. Cu Lo cells. Immunoblotting for indicated respiratory complex subunits. Red brackets indicate RSC. F, In-gel activity assay (IGA) for cytochrome c oxidase. RSCs are indicated with red brackets.
