Advanced hepatocellular carcinoma (HCC) is insensitive to traditional chemotherapeutic approaches, which causes difficulty in the development of novel agents for the treatment of HCC. Berberine is the main component of Coptidis Rhizoma, a plant alkaloid with a long history of use in Chinese medicine, and has become a potential candidate for the treatment of HCC due to its high antitumor activity and low toxicity. In this study, we investigated the mechanism via which berberine exerts its inhibitory effects on HCC. The data demonstrated that berberine selectively decreased cell viability in a time‑ and dose‑dependent manner in the HepG2, SMMC‑7721 and Bel‑7402 HCC cell lines compared with normal hepatocytes (HL‑7702 cells), as determined by a sulforhodamine B assay. Flow cytometric analysis revealed that berberine increased the number of late apoptotic cells. Pretreatment with berberine in HepG2 cells resulted in a significant increase in phosphorylated AMP‑activated protein kinase (AMPK), as well as a marked elevation in phosphorylated Akt levels. In addition, the activation of AMPK was accompanied by apoptotic effects that occurred in a caspase‑dependent manner through the mitochondrial pathway, and was coupled with the release of cytochrome c from the mitochondria and the activation of caspase‑9 and ‑3. Furthermore, the ratio of Bax/Bcl‑2 was increased in a dose‑dependent manner. Our study supports the theory that berberine selectively inhibits the growth of human hepatocellular cancer cells by inducing AMPK‑mediated caspase‑dependent mitochondrial pathway cell apoptosis, and rarely causes cytotoxicity in normal cells. Therefore, berberine is a promising novel agent for the treatment of HCC.
