It is noteworthy that our previous microarray analysis revealed a 7-fold increase in the expression of VEGF-correlated chemokine-1 (VCC-1) in bladder cancer cells with high OCT4 expression 6, suggesting a potentially significant correlation between VCC-1 and OCT4 in the progression of tumorigenesis. The gene discussed is CXCL17; the disease is urinary bladder cancer.
