Abstract
Background: The angiogenesis inhibitor, sorafenib, remains the only available therapy of hepatocellular carcinoma (HCC). Only recently, patents of VEGF receptors-3 inhibitors have been developed. Thus, a novel approach against HCC is essential for a better therapeutic outcome. Objective: The aims of this study were to examine the chemopreventive action of saffron’s main biomolecule, crocin, against chemically-induced liver cancer in rats, and to explore the mechanisms by which crocin employs its anti-tumor effects. Method: We investigated the anti-cancer effect of crocin on an experimental carcinogenesis model of liver cancer by studying the anti-oxidant, anti-inflammatory, anti-proliferation, pro-apoptotic activities of crocin in vivo. In addition, we provided a network analysis of differentially expressed genes in tissues of animals pre-treated with crocin in comparison to induced-HCC animal tissues. To further support our results, in vitro analysis was carried out. We assessed the effects of crocin on HepG2 cells viability by treating them with various concentrations of crocin. In addition, effects of crocin on cell cycle distribution of HepG2 cells were investigated. Results: Findings reported herein demonstrate the anti-proliferative and pro-apoptotic properties of crocin, when administrated in induced-HCC model. Crocin exhibited anti-inflammatory properties whereby NF-kB, among other inflammatory markers, was inhibited. In vitro analysis confirms crocin’s effect in HepG2 by arresting the cell cycle at S and G2/M phases, inducing apoptosis and downregulating inflammation. Network analysis identified NF-kB as a potential regulatory hub, and therefore a candidate therapeutic drug target. Conclusion: Taken together, our findings introduce crocin as a candidate chemopreventive agent against HCC.
