We also evaluated USP1 expression in bladder cancer using UALCAN (https://ualcan.path.uab.edu/, accessed on 16 May 2024), which indicated that USP1 expression was upregulated in bladder cancer, especially in non-papillary tumors and TP53-mutant tumors; however, no significant differences were observed among the different cancer stages or the nodal metastatic statuses (Figure S1). Here, TP53 is linked to cancer.
