Abstract: Hepatocellular carcinoma (HCC) is an aggressive disease with poor prognosis due to its high rate of recurrence after initial treatment. Therefore, the development of effective therapeutic strategies that can prevent recurrence and secondary tumor formation will improve the clinical outcome of HCC patients. A malfunction of the retinoid X receptor-α (RXRα) due to the activation of the Ras-MAPK signaling pathway is highly associated with hepatocarcinogenesis. Acyclic retinoid (ACR), which is one of synthetic retinoids, prevents HCC recurrence by inhibiting Ras-MAPK activation and subsequent RXRα phosphorylation, thus improving patient prognosis. Here, we review the detailed effects of ACR on the prevention of HCC development, based on the results of our basic and clinical research.

Abstract: The sorafenib, an oral multi-tyrosine kinase inhibitor, is currently approved by regulatory agencies as the standard-of-care first-line treatment of advanced hepatocellular carcinoma (HCC). Sorafenib is the first and so far the sole drug that has shown overall survival benefit in patients with advanced HCC in two III trials. The remarkable results obtained by sorafenib are contrasting with objective response rate inferior to 5% according to RECIST criteria. Distinct to standard chemotherapies, low objective response rates were also observed with other antiangiogenic agents tested in HCC. Tumor shrinkage and dimensional changes, usually assessed to define response to cytotoxic drugs based on morphological RECIST criteria, were rarely observed in patients treated with antiangiogenic therapies. Hence, Radiological evaluation of efficacy using standard RECIST criteria is often inappropriate to assess response to targeted agents in HCC patients. Alternatives criteria of response, such as mRECIST, EASL and CHOI criteria have been proposed to assess the direct effect of antianagiogenic therapies in HCC. In this review, we purpose to analyze relevance of these new criteria in clinical practice and their performance to predict response of antiangiogenic therapies for HCC.

Abstract: Hepatocellular carcinoma (HCC) is one of the most lethal malignancies due to underlying co-morbid cirrhosis and chemo-resistance. Vaccination and improved treatment for hepatitis are the most effective means to reduce the burden of liver cancer worldwide. Expression of biomarkers such as AFP, DDK1 and microRNAs in blood are being tested for early screening of liver cancer. Since 2008, sorafenib has been used as standard molecular targeted agent for HCC. However, overall outcomes for sorafenib alone or in combination with other tyrosine kinase inhibitors are unsatisfactory. Simultaneously or sequentially, addiction switches and compensatory pathway activation in HCC, induced by sorafenib treatment, may cause acquired resistance to sorafenib. FOXM1 and MTDH have been shown to be master regulators of different aspects of tumorigenesis, including angiogenesis, invasion, metastasis and drug resistance. Elevated expression of both FOXM1 and MTDH is known to be a consequence of both activating mutations in oncogenes such as PI3K, Ras, myc and loss of function mutations in tumor suppressor genes such as p53 and PTEN in various types of cancers including HCC. The role of FOXM1 and MTDH as potential prognostic markers as well as therapeutic targets in HCC will be discussed. In addition, microRNAs (miRNAs), endogenous small non-coding RNAs involved in the regulation of gene expression, are involved in HCC and interact with both FOXM1 and MTDH in several ways. Thus, altered expression of miRNAs in HCCs will also be discussed as potential tools for diagnosis, prognosis and therapy in HCC.

Title: Synergistic Anti-Cancer Activities Of Natural Substances in Human Hepatoma HepG2 Cells
Authors: Akiko Kojima-Yuasa 1, Xuedan Huang 2 and Isao Matsui-Yuasa 1

Abstract: Natural products are excellent sources for the development of new medications for disease treatment. Recently we and another researchers have been suggested that the combined effect of natural products may improve the effect of treatment against the proliferation of cancer cells. In this review we will introduce the combination of natural substances showing the synergistic anti-cancer effect in human hepatoma HepG2 cells and provide new insight into the development of novel combination therapies against hepatocellular carcinoma.
