"Whereas cco-1 RNAi did reduce oxygen consumption as expected, this reduction in oxygen consumption was not suppressed by atfs-1(lf) unlike cco-1 RNAi's hypoxia resistance (Figure S2E)."
cco-1(RNAi) was epistatic to the skn-1(zu67) mutation as the double mutant was long-lived like cco-1(RNAi) mutants, as opposed to skn-1(zu67) mutants, which were short-lived
