In agreement with our study, previous studies on human non-small cell lung cancer (NSCLC) and prostate cancer cell lines, PC3 and DU145, found that DHA induced cellular apoptosis through the over-production of ROS in the mitochondria, which caused inactivation of the PI3K/Akt pathway inhibiting growth and proliferation of cancer cells [62, 63]. This evidence concerns the gene AKT1 and cancer.
