In cancer treatment, herbal medicines may be a good choice because of the reduced risk of adverse side effects. Artemisia capillaris has been recognized as a promising candidate due to its hepatoprotective effects. Herein, we investigated whether A. capillaris-derived fraction (ACE-63) could inhibit the progression of hepatocellular carcinoma (HCC) and its underlying mechanism. In this study, ACE-63 effectively inhibited the growth and proliferation of HCC cells. ACE-63 induced apoptosis, as observed using Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, which was accompanied with increases in cleaved Poly (ADP-ribose) polymerase (PARP) and caspase-3 in HCC cells...

Hepatocellular carcinoma (HCC) is a major global health problem. Therapeutic interventions of HCC are still limited because of its complicated molecular pathogenesis. Many reports showed that renin-angiotensin system (RAS) contributes to the development of different types of malignancies. Therefore, the present study aimed to examine the effect of RAS inhibition using perindopril (1 mg/kg), fosinopril (2 mg/kg), or losartan (10 mg/kg) on diethylnitrosamine-induced HCC compared to sorafenib (30 mg/kg)...

BACKGROUND: Without an effective vaccine, hepatitis C virus (HCV) remains a global threat, inflicting 170-300 million carriers worldwide at risk of cirrhosis and hepatocellular carcinoma (HCC). Though various direct acting antivirals have been redeemed the hepatitis C treatment, a few restraints persist including possible side effects, viral resistance emergence, excessive cost which restricts its availability to a common person. HYPOTHESIS: There is no preventive HCV vaccine available today so the discovery of potent antiviral natural flora and their bioactive constituents may help to develop preventive cures against HCV infection...

Background: There are abundant glycyrrhetinic acid (GA) receptors on the cellular membrane of hepatocytes and hepatocellular carcinoma (HCC) cells. The receptor binding effect might be related to the structure of the guiding molecule. GA exists in two stereoisomers with C3-hydroxyl and C11-carbonyl active groups. Purpose: The objective of this study was to investigate the relationship between the HCC-targeted effect and the configurations and groups of GA. Methods and results: Different GA derivatives (18β-GA, 18α-GA, 3-acetyl-18β-GA [3-Ace-GA] and 11-deoxy-18β-GA [11-Deo-GA]) were used to investigate the targeting effect of GA's configurations and groups on HCC cells...

A prior screening programme carried out using MTT assay by our group identified a series of novel benzimidazole derivatives, among which Methyl 2-(5-fluoro-2-hydroxyphenyl)-1H- benzo[d]imidazole-5-carboxylate (MBIC) showed highest anticancer efficacy compared to that of chemotherapeutic agent, cisplatin. In the present study, we found that MBIC inhibited cell viability in different hepatocellular carcinoma (HCC) cell lines without exerting significant cytotoxic effects on normal liver cells. Annexin V-FITC/PI flow cytometry analysis and Western blotting results indicated that MBIC can induce apoptosis in HCC cells, which was found to be mediated through mitochondria associated proteins ultimately leading to the activation of caspase-3...

Since the majority of hepatocellular carcinoma (HCC) arises from a background of chronic liver diseases caused by infection with hepatitis C virus (HCV) and hepatitis B virus (HBV), chemoprevention targeting patients at high risk of HCC is feasible. In this review article, we summarize current knowledge of chemoprevention against HCC mostly using phytochemicals which have less toxicity than pharmaceutical agents. We describe in vivo and in vitro evidence and proposed mechanisms of beneficial effects of several compounds on the liver, including acyclic retinoid (ACR), angiotensin-converting enzyme inhibitors (ACEIs), caffeine, capsaicin, cepharanthine (CEP), cinnamaldehyde, curcumin, diallyl sulfide (DAS), eicosapentaenoic acid (EPA), epigallocatechin-3-gallate (EGCG), genistein, lycopene, resveratrol, silymarin, sulforaphane (SFN), and xanthohumol (XN)...

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Angiogenesis is reported to play a pivotal role in the occurrence, development and metastasis of HCC. The renin-angiotensin system (RAS) is involved in the regulation of angiogenesis. Here, based on the analysis of HCC datasets from Gene Expression Omnibus (GEO) database and The Cancer Genome Atlas (TCGA), we found that there was a negative correlation between the mRNA levels of angiotensin converting enzyme 2 (ACE2) and CD34. To explore the association of RAS with the progression from fibrosis to cirrhosis to HCC, liver specimens and serum samples were collected from patients with hepatic fibrosis, cirrhosis and HCC...

Replicating virus vectors are attractive tools for anticancer gene therapy, but the potential for adverse events due to uncontrolled spread of the vectors has been a major concern. To design a tumor-specific retroviral replicating vector (RRV), we replaced the U3 region of the RRV ACE-GFP with a regulatory sequence consisting of the hepatitis B virus enhancer II (EII) and human α-fetoprotein (AFP) core promoter to produce ACE-GFP-EIIAFP, a hepatocellular carcinoma (HCC)-targeting RRV. Similar to ACE-GFP, ACE-GFP-EIIAFP exhibited robust green fluorescent protein (GFP) expression in HCC cells and, most importantly, it exhibited HCC-specific replication and did not replicate in non-HCC tumor cells or normal liver cells...

Increasing evidence suggests that the renin-angiotensin system (RAS) plays an important role in tumorigenesis. The interaction between Angiotensin II (AngII) and angiotensin type 1 receptor (AT1R) may have a pivotal role in hepatocellular carcinoma (HCC) and therefore, AT1R blocker and angiotensin I-converting enzyme (ACE) inhibitors may have therapeutic potential in the treatment of hepatic cancer. Although the involvement of AT1R has been well explored, the role of the angiotensin II Type 2 receptor (AT2R) in HCC progression remains poorly understood...

No effective chemopreventive agent has been approved against hepatocellular carcinoma (HCC) to date. Since HCC is one of the hypervascular solid tumors, blocking angiogenesis represents an intriguing approach to HCC chemoprevention. The aim of the current study was to examine the combined effect of the anti-angiogenic agents: leflunomide; a disease modifying antirheumatic drug, perindopril; an angiotensin converting enzyme inhibitor (ACEI) and curcumin; the active principle of turmeric, on diethylnitrosamine (DEN)-induced HCC in mice...

Growing evidence suggests that the angiotensin-converting enzyme (ACE) and endothelial nitric oxide synthase (eNOS) genes are associated with risk in a wide range of cancers. The objective of this study was to examine whether two DNA polymorphisms at the ACE insertion/deletion (I/D) and the variable number of tandem repeats in NOS intron 4 (4a/4b) were linked to the risk of developing hepatocellular carcinoma (HCC) in a Chinese population. The polymorphisms at ACE I/D and eNOS 4a/4b were genotyped in 293 HCC patients and 384 healthy control subjects using polymerase chain reaction...

The identification of biomarkers of anti-angiogenic therapy that predict clinical benefit is of vital importance. We previously reported that a combination treatment with clinically available safe agents, specifically angiotensin-converting enzyme inhibitor (ACE-I) and vitamin K (VK), inhibited the cumulative recurrence of hepatocellular carcinoma (HCC) via suppression of the vascular endothelial growth factor (VEGF). The present study aimed to identify non-invasive biological markers that predict the clinically beneficial effect of this combination regimen...
