PCDHA7 and bladder transitional cell carcinoma: It was also observed that cell adhesion-related genes, including PCDHA7, PCDHGB2, and PCDHB10, and cell cycle-related genes such as CDK1, CDC7, and CDC14A, exhibited notably higher expression levels in BLCA patients with high expression of scaRNA12 when compared to those with low expression of scaRNA12 (Figure 2F).
