Fig. 4: PLA supplementation activate stress-response transcription factors SKN-1 and ATFS-1.

a Comparing the transcriptomes of the PLA-treated worm with those treated with either skn-1 RNAi or atfs-1 RNAi via scatter plots and Venn diagrams suggests that SKN-1 and AFTS-1 are crucial players generating the effect of PLA supplementation at the transcriptional level. b Hypothesis of PLA-induced longevity. PLA elevates organismal HAI with SKN-1/ATFS-1-mediated mitochondrial activation and stress resilience.
