The results showed thatPRR13 had the minimum negative score, compared withZNF330 andCHURC1 in 28 bladder cancer cell lines, suggesting that knockout ofPRR13 had the most significant inhibitory effect on the viability of bladder cancer cells (Fig. 4A).PRR13 was further included in the follow-up study. This evidence concerns the gene PRR13 and urinary bladder cancer.
