To determine YAP1-associated regulation of chemokines noted above in human UCB, we first performed RT-qPCR analysis of CXCR2-associated ligands (CXCL2, CXCL3, and CXCL6) in human cancer cell lines (T24, BFTC905, BFTC909, and UMUC3) with YAP1 modulation. The gene discussed is CXCL3; the disease is cancer.
