A review by Kuo et al. [147] describes various mechanisms of CAPE to induce cell cycle arrest and apoptosis in oral cancer, including inhibiting Akt signalling and regulating MMP activity, while another review by Lin et al. [148] describes the anticancer effects of CAPE, especially the inhibition of Akt signalling, in prostate cancer. Here, AKT1 is linked to prostate carcinoma.
