Sidak’s MC test, GFP control vs. GFP SSDS ns, p=0.9876. GFP SSDS vs. ZBT-OE SSDS **p = 0.0070. (K-L) RRHO comparing gene expression between indicated comparisons, in the context of mild stress. (M) Clustering at 1,929 DE genes between ZBT-OE SSDS and GFP SSDS. (N) Scaled Venn-diagram and odds ratio test of the overlap between differentially expressed (DE) genes in bulk OFC tissues comparing ZBT-OE stress vs. GFP SSDS, with GFP SSDS vs. GFP control. “J” indicates the Jaccard index. Note for GFP SSDS vs. GFP control, DEGs were defined at pval < 0.05 (O) GO analysis for gene DEGs in ZBT-OE SSDS vs. GFPSSDS and GFP SSDS vs. GFP control, separated by up/down regulation.
