For example, higher urinary exosomal LNMAT2 [28], higher urinary and serum exosomal circPRMT5, higher serum exosomal UCA1 [27], the PCAT-1, UBC1, SNHG16 panel [55], higher plasma exosomal H19 [56] and lower plasma exosomal PTENP1 were more frequently observed in bladder cancer patients than in healthy controls [26]. This evidence concerns the gene PCAT1 and urinary bladder cancer.
