Three pathways including dendritic cell maturation, apelin endothelial signaling pathway, and bladder cancer signaling were enriched in Treg from fibrosis kidney (E-MTAB-7961), and 71 specifically enriched pathway in Treg from regeneration kidney (E-MTAB-7961) were shown in supplementary Table 3B. This evidence concerns the gene APLN and urinary bladder cancer.
