Flow cytometric apoptotic analysis revealed that the co-treatment of curcumin (10 ng/mL) and gefitinib (0.1 mol/L) significantly augmented the apoptosis in NCI-H1975 lung cancer cells by blocking EGFR signalling pathways, notably Akt and ERK1/2 phosphorylation [93]. Here, AKT1 is linked to lung cancer.
