Circ_0006332 knockdown by siRNA significantly decreased the expression of MYBL2 (Figure 4C and Supplementary Figure 1B), whereas, overexpression of circ_0006332 (Supplementary Figure 1C) significantly increased the expression of MYBL2 in the bladder cancer cell lines T24 and UM-UC-3 (Figure 4D). This evidence concerns the gene MYBL2 and urinary bladder cancer.
