Fig. 1From: Dissecting the roles of thymoquinone on the prevention and the treatment of hepatocellular carcinoma: an overview on the current state of knowledgeKey signaling pathways that regulate the function of TQ in HCC develepoment and in the hepatic injury. The cartoon recapitulates the principle signaling pathways by which TQ blocks hepatocellular carcinoma growth (a) and the hepatic injury (b).
