CBX6 and urinary bladder cancer: The expression of CBX6 in the bladder cancer cell lines 5637 and T24 was lower than that in the normal bladder epithelial cell line SV-HUC-1 (Figure 11G), which was consistent with our previous results, shown in Figure 11F. However, CBX7 expression was higher in the bladder cancer cell line 5637 and lower in T24 than in SV-HUC-1 (Figure 11H).
