(A) Analysis of the replication kinetics of RV in Vero, MCF-7, and A549 cells and (B) activities of mitochondrial respiratory chain complexes I, II, III, and IV. (A) Mean RV genomic and subgenomic RNA copies were determined for 12, 24, 48, and 72 hpi by RT-qPCR. (B) Enzyme activities were determined by spectrophotometric assays and normalized to citrate synthase activity. Vero, MCF-7, and A549 cells were mock infected after 24 h of cultivation. Samples were collected at further incubation periods of 24, 48, and 72 h.
