MT-CYB and infection: Many RNA coding components of the mitochondrial respiratory chain, such as MT-CO1, MT-CYB, MT-ND2, MT-RNR2, MT-TE, MT-TI, MT-TP, and MT-TS1, were highly elevated in the Caco-2 cells cocultured aerobically with Salmonella compared to the cells without infection (Fig. 4C, Fig. S4, and Table S2) [35].
