Global transcriptional regulation of innate immunity by ATF-7 in C. elegans.
-
ATF-7 regulates over 50% of all pathogen-induced genes
"We observed that 70% of genes significantly induced two-fold or greater by P. aeruginosa exposure were no longer fully induced upon loss of pmk-1, and that 53% of upregulated genes were no longer fully induced upon loss of atf-7"
-
ChIP-seq identified 8,962 ATF-7 binding peaks genome-wide
"In all conditions analyzed, ATF-7 exhibited abundant association throughout the genome, with 8,962 total peaks identified as enriched by MACS2"
-
ATF-7 binds CRE-like motif 5'-GACgTCA-3'
"MEME analysis of the most enriched loci identified significant enrichment for the motif GACgTCA, which corresponds to the Jun D bZIP motif expected for ATF-7 (Fig 2A, S3B Fig)"
-
ATF-7 chromatin occupancy is PMK-1-dependent at pathogen-induced genes
"ATF-7 is preferentially located at the promoter regions of genes that are increased in expression by P. aeruginosa, and that this enrichment for ATF-7 is lessened by pmk-1 loss"
-
ATF-7 binds promoters of key stress response regulators (skn-1, xbp-1, lgg-1)
"ATF-7 exhibits binding affinity to regulators of autophagy (lgg-1), the Unfolded Protein Response (xbp-1), and the oxidative stress response (skn-1)"
-
Functional validation confirmed ATF-7 targets affect pathogen resistance
"RNAi of 13 of 43 genes conferred enhanced sensitivity to killing by P. aeruginosa, without affecting survival on non-pathogenic E. coli"
