Abstract

Chemokines play a critical role in lung cancer progression and metastasis. In non-small cell lung cancer, the determination of dominant angiogenic CXCL-type chemokines may increase the efficacy of targeted therapy and modulate the prognosis of lung cancer. Also, chemokine and chemokine receptors shape the immune response in the cross-talk between both cancer cells and immune cells in the tumor microenvironment. In this computational evaluation study based on databases containing mostly RNA-seq analyses, it is aimed to determine the dominant angiogenic CXCL-type chemokines with the highest expression in lung adenocarcinoma tissues and particularly in non-small cell lung cancer cells. CXCL1, CXCL5, CXCL7, and CXCL8, which can potentially be co-regulated and associated with poor survival, and phagocyte infiltration including neutrophils and macrophages are predominantly identified in non-small cell lung cancer. Moreover, the receptors of these chemokines, CXCR1 (binding CXCL8) and CXCR2 (binding CXCL1, 5, 7, 8), are positively correlated with the infiltration of neutrophils and macrophages. With the discovery of the common regulatory mechanisms of these angiogenic chemokines and validation studies in clinical examples, the chemokine panels specific to non-small cell lung cancer will become clear and have a decisive role in the prognosis of the disease.
