High mortality and morbidity rates for hepatocellular carcinoma (HCC) in Taiwan primarily result from uncontrolled tumor metastasis. Previous studies have identified thatTerminalia catappaleaf extracts (TCE) exert hepatoprotective, antioxidative, antiinflammatory, anticancer, and antimetastatic activities. However, the effects of TCE on HCC and the underlying molecular mechanisms of its activities have yet to be fully elucidated. The present study's findings demonstrate that TCE concentration dependently inhibits human HCC migration/invasion. Zymographic and western blot analyses revealed that TCE inhibited the activities and expression of matrix metalloproteinase-9 (MMP-9). Assessment of mRNA levels, using reverse transcriptase polymerase chain reaction (PCR) and real-time PCR, and promoter assays confirmed the inhibitory effects of TCE on MMP-9 expression in HCC cells. The inhibitory effects of TCE on MMP-9 proceeded by upregulating tissue inhibitor of metalloproteinase-1 (TIMP-1), as well as suppressing nuclear translocation and DNA binding activity of nuclear factor-kappa B (NF-κB) and activating protein-1 (AP-1) on the MMP-9 promoter in Huh7 cells. In conclusion, TCE inhibits MMP-9 expression and HCC cell metastasis and, thus, has potential use as a chemopreventive agent. Its inhibitory effects are associated with downregulation of the binding activities of the transcription factors NF-κB and AP-1.

e22103 Background: Curcumin regulates the expression and secretion of MMPs, and has potent anti-cancer properties in several human cancer cell lines and animal carcinogenesis models. In this study we try to investigate the effects of polymeric nanoparticle encapsulated formulation of curcumin– nanocurcumin (NC) on Hepatocellular carcinoma (HCC) in vitro and in vivo. Methods: The effects of NC alone and in combination with sorafenib (SO) were investigated on HCC cell lines, Huh7 and MHCCLM3 in vitro by using proliferation and invasion assay, western blot, qRT-PCR, enzyme-linked immunosorbent assay and immunohistochemistry staining, and the subcutaneous and orthotopic HCC xenograft nude mice models (MHCCLM3) were used to evaluate primary tumor growth and metastasis after treatments. Results: NC alone (or combined with SO)inhibited HCC cell proliferation (p<0.05) and invasion in vitro (p<0.01), and remarkably decreased both the subcutaneous and orthotopic primary tumor growth and lung metastases in vivo. NC and/or SO could down-regulating the expressions of Matrix Metalloproteinase-9 (MMP9), p-ERK1 and NF-kB/p65 (p<0.05). Conclusions: NC showed potent anti-invasion and metastasis properties in HCC via NF-κB mediated MMP9 down-regulation, which may provide a new strategy to the treatment of HCC patients and prevention of tumor recurrence after operation.
