Conclusiveness is also limited due to lack of data regarding PELP1 in bladder cancer but assuming negative correlation between PELP1 and miR-200 family (66) and the fact that these miRNAs are directly repressed by Twist-related protein 1 (TWIST1) in bladder cancer (67) whose expression decreases with the PELP1 knockdown (68), we can assume that its role is not without significance. This evidence concerns the gene TWIST1 and urinary bladder cancer.
