Compared with WT ureters, the Elf3 expression level in Col17a1 -KO ureters showed a trend toward a significant difference only at 2 weeks ( P = 0.057), whereas the forkhead box A1 ( Foxa1 ) level showed a significant difference at 1 day and a trend toward a significant difference at 2 weeks ( P = 0.057), consistent with Upk2 expression dynamics (Figs 6 B and C).
