The results of the analysis showed that seven genes (VCL, FLNA, THBS1, TAGLN, ACTA2, COL6A2, and CALD1) were significantly correlated (P < 0.05) with the prognosis of bladder cancer patients, and these genes were included in the subsequent in-depth study (Figure 8A). Here, VCL is linked to urinary bladder carcinoma.
