(Submitter supplied) Mild deficits in mitochondrial function have been shown to increase lifespan in multiple species including worms, flies and mice. Here, we study three C. elegans mitochondrial mutants (clk-1, isp-1 and nuo-6) to identify overlapping genetic pathways that contribute to their longevity. We find that genes regulated by the FOXO transcription factor DAF-16 are upregulated in all three strains, and that the transcriptional changes present in these worms overlap significantly with the long-lived insulin-IGF1 signaling pathway mutant daf-2. 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) 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) Long-lived genetic mutants from different pathways of lifespan extension were used to determine the extent to which there are common downstream mediators of longevity. We have previously obtained RNA-sequencing data from other long-lived mutants including sod-2, clk-1, isp-1, nuo-6 and daf-2. Gene expression will be compared between these nine long-lived mutants.

(Submitter supplied) Oxidative stress may play a role in normal aging. SKN-1 is a transcription factor necessary for intestine development in Caenorhabditis elegans, which also regulates the response to oxidative stress post-embryonically. Using DNA microarrays, we found that oxidative stress induces the antioxidant response, the heat shock response, and detoxification genes, while the expression of genes involved in homeostasis, development, and reproduction were decreased. more...

(Submitter supplied) Background: Arsenite is one of the most toxic chemical substances known and is assumed to exert detrimental effects on viability even at lowest concentrations. By contrast and unlike higher concentrations, we here find that exposure to low-dose arsenite promotes growth of cultured mammalian cells. In the nematode C. elegans, low-dose arsenite promotes resistance against thermal and chemical stressors, and extends lifespan of this metazoan, whereas higher concentrations reduce longevity. more...
