(Submitter supplied) We have shown that worms that possess mutations in two electron transport chain subunits live longer due to mtROS signalling. Wild type worms can also live longer by treatment with the pro-oxidant paraquat. Paraquat treatment is not additive to the mutations in the ETC subunits. We aimed to determine the underlying changes in gene expression that were common to both paraquat treatment and the two mutations. more...

(Submitter supplied) In this work, we examined the effect of the transcription factor ATFS-1 in the long lifespan of the nuo-6 mitochondrial mutant. We also examined the effect of the hypoxia transcription factor hif-1. We sequenced both atfs-1 deletion mutants and atfs-1 gain-of-function point mutants in which the mitochondrial localization sequence of ATFS-1 is disrupted. Note that sequencing batch 2 was previously uploaded as part of GSE93724.

(Submitter supplied) To gain insight into the pathways accounting for the deleterious effects associated with severe mitochondrial dysfunction, we compared the transcriptomic profile in control L3 larvae with that of strong (arrested) nuo-5 RNAi. We also found that the natural compound lutein was able to rescue some of the defective phenotypes we characterized in nuo-5-depleted animals therefore we compared also the transcriptomic profile of stage-matched (L3) cohorts of C. more...

(Submitter supplied) In this study we compared the transcriptomic profile in control L3 larvae with that of mild or strong (arrested) nuo-5 RNAi. The two treatment (mild and strong) in fact lead to two very different phenotype. The mild supperssion of nuo-5 induces improved healthspand and has pro longevity effect. The strong suppression of the same gene has, on the contrary, deleterious effects such as arrested development.
