However, in another lung cancer study, inhibition of GRK6 was shown to promote the activity of host C‐X‐C chemokine receptor 2 signaling, followed by increased polymorphonuclear neutrophils infiltration and MMP release in the tumor microenvironment, facilitating angiogenesis and metastasis of lung cancer. The gene discussed is CXCR2; the disease is lung carcinoma.
