Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and the second most common cause of cancer death worldwide. Current treatment options for patients with intermediate and advanced HCC are limited, and there is an unmet need for novel therapeutic approaches. HCC is an attractive target for immunomodulation therapy, since it arises in an inflammatory milieu due to hepatitis B and C infections and cirrhosis. However, a major barrier to the development and success of immunotherapy in patients with HCC is the liver's inherent immunosuppressive function...

Most hepatitis C virus (HCV) infection results in persistent infection. Significant portion of chronic HCV-infected patients develop hepatocellular carcinoma (HCC). Chronic hepatitis C is also associated with extrahepatic manifestations, including cryoglobulinemia, lymphoma, insulin resistance, type 2 diabetes, and neurological disorders. The molecular mechanisms of how HCV infection causes liver cancer are largely unknown. HCV replication or viral proteins may perturb cellular hemostasis and induce the generation of reactive oxygen species (ROS); viral components or viral replication products act as agonist to trigger innate immune response and cause chronic inflammation...

REVIEW
Hwi Young Kim, Joong-Won Park
Hepatocellular carcinoma (HCC) is a common and serious health problem with high mortality. Treatment for HCC remains largely unsatisfactory owing to its high recurrence rates and frequent accompanying cirrhosis. In addition, the unique immune environment of the liver promotes tolerance, which, in conjunction with immune evasion by the disease, makes HCC a less promising target for conventional immunotherapy. However, recent advances in the immunotherapy have led to novel approaches to overcome these obstacles by manipulating and enhancing tumor-specific immune responses against HCC by using various modalities, such as cancer vaccines and immune checkpoint blockade...

The down-regulation of eukaryotic elongation factor-2 kinase (eEF2K) is associated with an enhancement in the sensitivity of malignant cells to chemotherapeutic agents. In this study, we found that the silencing of eEF2K enhanced cisplatin (CDDP)-induced cytotoxicity in CDDP-sensitive (HepG2) and resistant (HepG2/CDDP) cells. Calyxin Y, a unique chalcone diarylheptanoid adduct, down-regulated eEF2K by promoting Skp1-Cul1-F-box protein (SCF) β-transducin repeat-containing protein (βTrCP)-mediated protein degradation and synergistically enhanced the cytotoxicity of CDDP...

Tumor angiogenesis plays a central role in the development and metastasis of hepatocellular carcinoma. Cancer cells secrete angiogenic factors to recruit vascular endothelial cells and sustain tumor vascular networks, which facilitate the migration and invasion of cancer cells. Therefore, the cross-talk between vascular endothelial cells and cancer cells is vitally necessary, however, little is known about the cross-talk mechanism of these cells interaction. In the present study, the proliferation, migration, invasion and tube formation of vascular endothelial EA...

American ginseng as a common and traditional herbal medicine has been used in cancer treatment for many years. However, the effect of American ginseng on the cancer cell response (i.e. apoptosis) has not been fully understood yet. Previous studies demonstrated that cellular apoptosis was associated with the changes of mechanical and morphological properties. Therefore, in this study, mechanical and morphological characterizations were carried out by both atomic force microscope (AFM) and inverted optical microscope to investigate the apoptosis of hepatocellular carcinoma (SMMC-7721) cells affected by American ginseng root water extract (AGRWE)...

Liang Ma, Lei Peng, Sheng Fang, Bangguo He, Zi Liu
Celastrol, a natural compound extracted from Tripterygium wilfordii, is known to exhibit potential anticancer activities in various types of tumor cells. E2F1 is reported to be overexpressed in several types of human tumors and its inactivation may be a valuable novel potential therapeutic strategy for cancer treatment. However, the molecular mechanism underlying the pro-apoptotic effects of celastrol on hepatocellular carcinoma (HCC) cells remains unclear, and E2F1-targeted compounds have been rarely identified...

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and the third leading cause of cancer-related death. Telmisartan, a widely used antihypertensive drug, is an angiotensin II type 1 (AT1) receptor blocker (ARB) that might inhibit cancer cell proliferation, but the mechanisms through which telmisartan affects various cancers remain unknown. The aim of the present study was to evaluate the effects of telmisartan on human HCC and to assess the expression of microRNAs (miRNAs). We studied the effects of telmisartan on HCC cells using the HLF, HLE, HepG2, HuH-7 and PLC/PRF/5 cell lines...

Hepatitis B virus (HBV) is the dominant risk factor for hepatocellular carcinoma (HCC). HBV X protein (HBx) plays crucial roles in HCC carcinogenesis. HBx interferes with several signaling pathways including the Notch1 pathway in HCC. In this study, we found that Notch1 was highly expressed in HCC, especially in large HCCs. Notch1 and HBx co-localized in HCC and their levels were positively correlated with each other. Notch1 expression was more elevated in HepG2.2.15 cells than that in HepG2 cells. HBx activated the Notch1 pathway in HepG2...

HAb18G/CD147, an important marker in the progression of hepatocellular carcinoma (HCC), is highly expressed on the surface of HCC cells. To increase the therapeutic efficacy of Doxil (PEGylated liposomal doxorubicin) against HCC, we constructed CD147-targeted doxorubicin-loaded immunoliposomes (Anti-CD147 ILs-DOX) by conjugating F(ab')2 of a CD147-specific monoclonal antibody to DSPE-PEG-MAL, and then inserted the antibody-conjugated polymer to Doxil. Anti-CD147 ILs-DOX delivered DOX to CD147-overexpressing HCC cells specifically and efficiently in vitro and in vivo, resulting in enhanced therapeutic effects than non-targeted controls...
