Cancer‐related reports involve a large quantity of data on the effects of EVs circRNAs.27 EVs significantly influence cell‐cell communication and jointly change the physiological function of the recipient cells with bioactive factors, including circRNAs.28 For instance, EVs from normal cells transferred PTENP1 to bladder cells, which suppresses bladder cancer progression.29 With efforts made in this study, it was concluded that circ‐0000190 level was elevated in EVs from normal cells, about four times greater than that in producer cells. This evidence concerns the gene PTENP1 and urinary bladder carcinoma.
