Echinoderm microtubule associated protein-like 4-anaplastic lymphoma kinase (EML4-ALK) fusion gene is lung cancer-driven gene [141], EML4 and ALK two genes located on human chromosome 2 p21 and p23, intracellular ALK gene and with the N-terminal EML4 inverted fusion induces tyrosine kinase activity by stimulating the PI3K/AKT/MAPK signaling pathway, resulting in the proliferation and differentiation of tumor cells and the inhibition of apoptosis [142]. Here, EML4 is linked to neoplasm.
