In the present research, it was approved in A549 cells that the NE-induced up-regulation in both protein and gene levels of VEGF, IL-8 and IL-6 was chiefly mediated by β-AR/cAMP/PKA signaling pathway which had been found to play a key role in mouse xenografts of melanoma and ovarian cancer[9,17]. Here, CXCL8 is linked to ovarian cancer.
