Abstract
Hepatocellular carcinoma (HCC) is a common cancer in the world, and its incidence is increasing yearly. Hepatitis B virus (HBV) infection and hepatitis C virus (HCV) infection are important causes of HCC. Liver cirrhosis, age, sex, smoking and drinking, and metabolic risk factors will increase the risk of cancer in HBV/HCV patients. And viral load, APRI, FIB-4, and liver stiffness can all predict the risk of HCC in patients with viral infection. In addition, effective prevention strategies are essential in reducing the risk of HCC. The prevention of HCC involves mainly tertiary prevention strategies, while the primary prevention is based on standardized vaccine injections to prevent the occurrence of HBV/HCV. Eliminating the route of transmission and vaccination will lead to a decrease in the incidence of HCC. Secondary prevention involves effective antiviral treatment of HBV/HCV to prevent the disease from progressing to HCC, and tertiary prevention is actively treating HCC to prevent its recurrence.

Abstract
Viruses are obligate parasites dependent on host cells for survival. Viral infection of a cell activates a panel of pattern recognition receptors that mediate antiviral host responses to inhibit viral replication and dissemination. Viruses have evolved mechanisms to evade and subvert this antiviral host response, including encoding proteins that hijack, mimic and/or manipulate cellular processes such as the cell cycle, DNA damage repair, cellular metabolism and the host immune response. Currently, there is an increasing interest whether viral modulation of these cellular processes, including the cell cycle, contributes to cancer development. One cellular pathway related to cell cycle signalling is the Wnt pathway. This review focuses on the modulation of this pathway by human viruses, known to cause (or associated with) cancer development. The main mechanisms where viruses interact with the Wnt pathway appear to be through (i) epigenetic modification of Wnt genes; (ii) cellular or viral miRNAs targeting Wnt genes; (iii) altering specific Wnt pathway members, often leading to (iv) nuclear translocation of β-catenin and activation of Wnt signalling. Given that diverse viruses affect this signalling pathway, modulating Wnt signalling could be a generalised critical process for the initiation or maintenance of viral pathogenesis, with resultant dysregulation contributing to virus-induced cancers. Further study of this virus-host interaction may identify options for targeted therapy against Wnt signalling molecules as a means to reduce virus-induced pathogenesis and the downstream consequences of infection.

Comparative study of the different activities of hepatitis B virus whole-X protein and HBx in hepatocarcinogenesis by proteomics and bioinformatics analysis. Arch Virol 2015; 160:1645-56. [PMID: 25913689 DOI: 10.1007/s00705-015-2421-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2014] [Accepted: 04/04/2015] [Indexed: 01/30/2023]
Abstract
The hepatitis B virus (HBV) whole-X gene comprises the HBV X gene and the 168-bp region immediately upstream. Although the functions of HBx in hepatocarcinogenesis are well known, the activity of the HBV whole-X protein (HBwx), with 56 additional amino acids, has not yet been explored. In this study, proteomic and bioinformatic analysis was done to determine the protein interaction profiles of HBwx and HBx and to describe their functions in carcinogenesis. A total of 203 proteins were identified that interacted with HBwx, of which 149 were unique, the rest interacting also with HBx, and 73% (148/203) of these proteins are involved in carcinogenesis. Gene ontology (GO) analysis showed that HBwx- and HBx-interacting proteins are involved in different processes, the former mainly in biosynthetic processes (glycolysis, cell-cycle functions, and protein folding), and the latter mainly in localization, viral transcription, biological adhesion and angiogenesis. Pathway networks analysis revealed that proteins interacting with HBx participate mainly in oxidative phosphorylation, localization, the cytoskeleton, and cell adhesion. In contrast, more-specific functional analysis showed that proteins interacting with HBwx are involved in apoptosis and survival, cell-cycle functions, glycolysis, and gluconeogenesis (Pathway Maps); to cellular macromolecular complex assembly, protein folding and mRNA metabolic process (GO Processes); and to regulation of protein folding in the endoplasmic reticulum and cytoplasm, transcription, cell cycle G2-M and cytoskeleton rearrangement (Process Networks). In conclusion, this study shows that HBwx functions in carcinogenesis in a way that is different from that of HBx.

Abstract
This study aims to investigate the inflammatory response characteristics of liver cells caused by HBV x protein (HBx) and the unique function of the PGE2 inhibitor on HBx-positive liver cells. Tetrazolium blue colorimetric method, flow cytometry, and Western blot were performed to detect the proliferation, cycle, and apoptosis protein expression of HBx-positive HL7702 liver and control cells. The effect of the PGE2 inhibitor 15-Deoxy-Δ(12,14)-prostaglandin J2 (15d-PGJ2) on the growth of HL7702-HBx was also observed. HBx induces the PGE2 accumulation in HL7702 liver cells and promotes their growth and inhibits their apoptosis. HL7702-HBx and HL7702 cells showed increased apoptosis rate, increased apoptosis-promoting protein expression, and reduced apoptosis-inhibiting protein expression under the effect of 15d-PGJ2, and the changes in HL7702-HBx cells were more significant than in HL7702 cells. HBx expression causes liver cells to be more sensitive to the apoptosis-promoting function of 15d-PGJ2. Therefore, the use of 15d-PGJ2 may be a new method for the prevention or treatment of inflammatory changes to cancer caused by HBV infection in liver cells.

Abstract
Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent cancers in many developing countries including India. Among the various etiological factors being implicated in the cause of HCC, the most important cause, however, is hepatitis B virus (HBV) infection. Among all HBV genes, HBx is the most critical carcinogenic component, the molecular mechanisms of which have not been completely elucidated. Despite its clinical significance, there exists a very elemental understanding of the molecular, cellular, and environmental mechanisms that drive disease pathogenesis in HCC infected with HBV. Furthermore, there are only limited therapeutic options, the clinical benefits of which are insignificant. Therefore, the quest for novel and effective therapeutic regimen against HBV-related HCC is of paramount importance. This review attempts to epitomize the current state of knowledge of this most common and dreaded liver neoplasm, highlighting the putative treatment avenues and therapeutic research strategies that need to be implemented with immediate effect for tackling HBV-related HCC that has plagued the medical and scientific fraternity for decades. Additionally, this review proposes a novel "five-point" management algorithm for HBV-related HCC apart from portraying the unmet needs, principal challenges, and scientific perspectives that are relevant to controlling this accelerating global health crisis.

Abstract
An understanding of oncogenesis can be fostered by an integration of mechanistic studies with evolutionary considerations, which help explain why these mechanisms occur. This integration emphasizes infections and mutations as joint essential causes for many cancers. It suggests that infections may play a broader causal role in oncogenesis than has been generally appreciated. An evolutionary perspective also suggests that oncogenic viruses will tend to be transmitted by routes that provide infrequent opportunities for transmission, such as transmission by sexual and salivary contact. Such routes increase the intensity of natural selection for persistence within hosts, and molecular mechanisms for persistence often compromise critical barriers to oncogenesis, particularly cell cycle arrest, apoptosis, and a cap on the total number of divisions that a cell can undergo.

Abstract
AIM: To determine whether the hepatitis B virus X (HBV X) gene is involved in the pathogenesis of hepatitis B-related cirrhosis.
METHODS: A eukaryotic expression vector containing the HBV X gene (pHBV-X-IRES2-EGFP) was constructed and transfected into HL-7702 cells. The transfected cells were divided into two groups. One group was selected with G418 and named L02/x, which could express the HBV X gene stably, and another group was transfected with pHBV-X-IRES2-EGFP for 48 h and named L02/48x. The expression of HBV X was detected by real-time PCR and Western blot. L02/x and L02/48x cells were then co-cultured with hepatic stellate cells (HSCs) for 36 h, and the proliferation and migration of HSCs were detected.
RESULTS: Real-time PCR and Western blot analyses showed that L02/x and L02/48x cells could express HBV X. Compared to HSCs co-cultured with HL-7702 cells transfected with empty vector and non-transfected cells, the proliferation and migration of HSCs co-cultured with L02/x or L02/48x cells significantly increased.
CONCLUSION: The expression of the HBV X gene in HL-7702 cells could promote the proliferation and migration of HSCs and may play an important role in the pathogenesis of hepatitis B virus-induced liver fibrosis.
