Further, peridinin exerts anti-proliferative and pro-apoptotic effects in vitro by suppressing NF-κB and Akt signaling in HTLV-1-infected T cells [57], and the algal PCP complex exhibits antioxidant, anti-inflammatory, and anti-cancer activity against human metastatic breast adenocarcinoma (MDA-MB-231) cancer cells [58]. This evidence concerns the gene AKT1 and cancer.
