This study found that safranal has chemopreventive effects against liver cancer and investigated its mechanisms of action. Safranal was found to significantly inhibit proliferation and induce apoptosis in both rat and human liver cancer cells, and it also exhibited anti-inflammatory properties.
Despite all efforts, an effective and safe treatment for liver cancer remains elusive. Natural products and their derived biomolecules are potential resources to mine for novel anti-cancer drugs. Chemopreventive effects of safranal, a major bioactive ingredient of the golden spice saffron, were evaluated in this study against diethylnitrosamine (DEN)-induced liver cancer in rats. Safranal's mechanisms of action were also investigated in the human liver cancer line HepG2. When administered to DEN-treated rats, safranal significantly inhibited proliferation (Ki-67) and also induced apoptosis (TUNEL and M30 CytoDeath). It also exhibited anti-inflammatory properties where inflammatory markers such as NF-kB, COX2, iNOS, TNF-alpha, and its receptor were significantly inhibited. Safranal's in vivo effects were further supported in HepG2 cells where apoptosis was induced and inflammation was downregulated. In summary, safranal is reported here as a potent chemopreventive agent against hepatocellular carcinoma that may soon be an important ingredient of a broad-spectrum cancer therapy.
