Six common TJ-related genes were analyzed, namely, OCLN, ZO-1, JAMA, CLDN1, CLDN2, and CLDN4. There were no significant changes in the transcription level of these genes after CS treatment in bladder tumor cells (Figure 7B, Supplementary Table S1, p > 0.05). The gene discussed is F11R; the disease is urinary bladder neoplasm.
