Dieckol’s anticancer property against the non-small–cell lung cancer (NSCLC) cell line A549 is mediated by the inhibition of the invasive and migratory properties of A549 cells, as well as induction of apoptosis via inhibition of Pi3K/AKT/mTOR signaling and activation of the tumor suppressor protein E-cadherin, indicating that dieckol is a potent natural anticancer drug to treat NSCLC [36,37]. The gene discussed is AKT1; the disease is non-small cell lung carcinoma.
