EGFR and cancer: Treatment with asiatic acid significantly (i) reduced viability of A549 and H1975 cells while remaining non-toxic to BEAS-2B normal lung cells, (ii) enhanced cancer cell apoptosis, (iii) suppressed extracellular signal-regulated kinase (ERK) and protein kinase B (Akt) signaling pathways, and (iv) inhibited EGFR activation in A549 and H1975 cells.
