Abstract

The aim of the present study was to investigate the mechanism underlying the antitumor effects of ent-11α-hydroxy-15-oxo-kaur-16-en-19-oic-acid (5F) in colorectal cancer (CRC). 5F was isolated and used to treat C26 murine colon carcinoma cells, a xenograft tumor mouse model (induced by C26 cells) and a CRC mouse model [induced by 1,2-dimethylhydrazine (DMH)/dextran sodium sulfate (DSS)]. C26 cell growth was inhibited by 5F in a dose-and time-dependent manner in vitro. In addition, 5F induced cell apoptosis and cell cycle arrest in the G2 phase, increased the activity of caspase-3 and caspase-9, but did not affect the activity of cascase-8, suggesting that 5F induced apoptosis via activation of the mitochondrial signaling pathway rather than the death-receptor signaling pathway. Furthermore, treatment of C26 cells with 5F resulted in upregulation of cyclin-dependent kinase inhibitor 1A (p21, Cip1), Bcl-2-associated X protein, nuclear factor of κ light polypeptide gene enhancer in B-cells inhibitor, α and downregulation of B-cell lymphoma 2, nuclear factor κ-light-chain enhancer of activated B cells and survivin. In vivo animal models demonstrated that 5F treatment protected mice from carcinogenesis induced by DMH/DSS and markedly decreased the xenograft tumor weight with minimal side effects. Therefore, 5F may have potential as an anti-CRC therapeutic agent for use in the clinical setting.
