GHRH antagonist inhibits focal adhesion kinase (FAK) and decreases expression of vascular endothelial growth factor (VEGF) in human lung cancer cells in vitro

► GHRH antagonist inhibits focal adhesion kinase signaling in lung cancer cells. ► GHRH antagonist decreases the expression of factors involved in angiogenesis and invasion of lung cancer cells. ► The study contributes to the further understanding of the processes which govern the mechanism of action of GHRH and its antagonists in cancers.
