In summary, the expression of ATAD3A mRNA in normal bladder tissue in the age group over 40 was higher than that in the younger age group, as shown in Figure 1F, and ATAD3A mRNA levels were significantly higher in any molecular subtype, histological subtype, individual cancer stage, TP53 mutation status, and sample type than in normal bladder tissue, as shown in Figure 1G–K. Here, ATAD3A is linked to cancer.
