Abstract
INTRODUCTION One of the most prevalent primary liver cancer, particularly in Eastern Asia, is hepatocellular carcinoma (HCC), which has a poor prognosis. A rare condition known as situs inversus totalis (SIT) causes the abdominal and thoracic organs to be completely inverted. PRESENTATION OF CASE A 51-year-old woman complained of a lump in the abdomen since 4 years ago, slowly enlarging to the suprapubic area, without pain. Laboratory findings showed an alpha-fetoprotein level was 13.24 IU/mL. A three-phase abdominal CT scan showed a left lobe hepatoma with local metastases and situs inversus totalis. The patient was diagnosed with left lobe HCC cT2N0M0, stage II, Barcelona Clinic Liver Cancer (BCLC) A, Child-Pugh A, Karnofsky 80 % and SIT. In this case, segment II, III, and IV left hepatectomy was performed with the crushing clamp technique. The main challenges during surgery were the inverted intra-abdominal organs, where the liver was located on the left and the spleen on the right, and the very large tumor size of approximately 28 cm × 20 cm. DISCUSSION This interesting case creates challenges in clinical practice, particularly in surgery, due to the reversal of the normal anatomy. Thus, accurate imaging is crucial for diagnosis and treatment planning. The surgeon should remain adaptable while performing the procedure for mirrored anatomy in situs inversus. CONCLUSION The unique anatomy may make the liver resection procedure for HCC in patients with SIT challenging. Surgery involving these patients with inverted anatomy can be assisted by the appropriate preoperative imaging and staging using BCLC.

Integrated virtual screening and MD simulation approaches toward discovering potential inhibitors for targeting BRPF1 bromodomain in hepatocellular carcinoma. J Mol Graph Model 2024; 126:108642. [PMID: 37797430 DOI: 10.1016/j.jmgm.2023.108642] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 09/21/2023] [Accepted: 09/26/2023] [Indexed: 10/07/2023]
Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive and life-threatening cancers. Although multiple treatment options are available, the prognosis of HCC patients is poor due to metastasis and drug resistance. Hence, discovering novel targets is essential for better therapeutic development for HCC. In this study, we used the cancer genome atlas (TCGA) dataset to analyze the expression of bromodomain-containing proteins in HCC, as bromodomains are emerging attractive therapeutic targets. Our analysis identified BRPF1 as the most highly upregulated gene in HCC among the 43 bromodomain-containing genes. Upregulation of BRPF1 was significantly associated with poorer patient survival. Therefore, targeting BRPF1 may be an approach for HCC treatment. Previously, several potential inhibitors of BRPF1 bromodomain have been discovered. However, due to the limited clinical success of the current inhibitors, we aim to search for new inhibitors with high affinity and specificity for the BRPF1 bromodomain. In this study, we utilized high-throughput virtual screening methods to screen synthetic and natural compound databases against the BRPF1 bromodomain. In addition, we used machine learning-based QSAR modeling to predict the IC50 values of the selected BRPF1 bromodomain inhibitors. Extensive MD simulations were used to calculate the binding free energies of BRPF1 bromodomain and inhibitor complexes. Using this approach, we identified four lead scaffolds with a similar or better binding affinity towards the BRPF1 bromodomain than the previously reported inhibitors. Overall, this study discovered some promising compounds that have the potential to act as potent BRPF1 bromodomain inhibitors.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related morbidity and mortality worldwide. Current therapeutic approaches suffer significant side effects and lack of clear understanding of their molecular targets. Recent studies reported the anticancer effects, immunomodulatory properties, and antiangiogenic effects of the human amniotic membrane (hAM). hAM is a transparent protective membrane that surrounds the fetus. Preclinical studies showed pro-apoptotic and antiproliferative properties of hAM treatment on cancer cells. Herein, we present the latest findings of the application of the hAM in combating HCC tumorigenesis and the underlying molecular pathogenies and the role of transforming growth factor-beta (TGFβ), P53, WNT/beta-catenin, and PI3K/AKT pathways. The emerging clinical applications of hAM in cancer therapy provide evidence for its diverse and unique features and suitability for the management of a wide range of pathological conditions.

Abstract
Hepatocellular carcinoma (HCC) in a non-fibrotic liver (F0) is considered to be rare, and there is a marked paucity of studies in the literature on this HCC type. A review of the literature shows some important clinical and tumor characteristics: (a) it occurs mainly in young female and elder male patients; (b) clinically, under normal hepatic function, alpha-fetoprotein level is often normal, and there are no risk factors; (c) associated with metabolic disease; (d) macroscopically, single large lesions are noted; and (e) microscopically, the lesions are well-differentiated and encapsulated. Radiological imaging results are straightforward, showing arterial hyperenhancement and later wash-out. The combined use of B-mode and contrast-enhanced (CE) ultrasound (US) is the most reliable and cost-effective diagnostic method. Few peri-and post-operative complications are noted and 5-year survival is not inferior to patients with HCC on fibrosis liver despite the lesion's large size. Most clinicians believe that HCC is unlikely to occur if patients have no symptoms and normal hepatic function. Although detailed clinical data are very limited, we expect that this review will help to improve the clinical management of HCC in non-fibrotic livers.

Abstract
Liver cancer is the sixth most prevalent cancer and ranks third in cancer-related death, after lung and colorectal cancer. Various natural products have been discovered as alternatives to conventional cancer therapy strategies, including radiotherapy, chemotherapy, and surgery. Curcumin (CUR) with antiinflammatory, antioxidant, and antitumor activities has been associated with therapeutic benefits against various cancers. It can regulate multiple signaling pathways, such as PI3K/Akt, Wnt/β-catenin, JAK/STAT, p53, MAPKs, and NF-ĸB, which are involved in cancer cell proliferation, metastasis, apoptosis, angiogenesis, and autophagy. Due to its rapid metabolism, poor oral bioavailability, and low solubility in water, CUR application in clinical practices is restricted. To overcome these limitations, nanotechnology-based delivery systems have been applied to use CUR nanoformulations with added benefits, such as reducing toxicity, improving cellular uptake, and targeting tumor sites. Besides the anticancer activities of CUR in combating various cancers, especially liver cancer, here we focused on the CUR nanoformulations, such as micelles, liposomes, polymeric, metal, and solid lipid nanoparticles, and others, in the treatment of liver cancer.

Impact of eradication of hepatitis C virus on liver-related and -unrelated diseases: morbidity and mortality of chronic hepatitis C after SVR. J Gastroenterol 2022; 58:299-310.

Abstract
Hepatitis C virus infection is characterized by chronic liver inflammation and fibrogenesis, leading to end-stage liver failure and hepatocellular carcinoma over the course of 20 to 30 years. It seems not only the chronicity of hepatitis C but also the presence of the virus in non-hepatic tissues creates a favorable environment for the potential development of pathogenic impacts on extrahepatic systems and organs. Numerous extra-hepatic manifestations have been reported in association with HCV infection, all of which can substantially affect morbidity, mortality, and quality of life. With the recent development of DAAs, antiviral treatment can cure almost all patients with HCV infection, even those intolerant of or unresponsive to IFN treatment, and several large multicenter studies have confirmed the association of DAA-induced SVR with reductions in liver-related and liver-unrelated complications, such as cardiovascular events, end stage renal disease, and so on. Because, in addition to liver-related diseases, extrahepatic lesions are threatening for patients, it is important to eradicate the virus before these progress and affect life prognosis; in other words, patients should be treated before reaching the point of no return. Tailored surveillance with biomarkers such as M2BPGi and Ang-2, which can be used to identify patients with an elevated risk of EHM, and early prevention or treatment for these patients could improve the morbidity, mortality and QOL. Advancement of both basic and clinical research in this field including the development of more precise biomarkers is highly anticipated.

Abstract
There is not much information on hepatocellular carcinoma (HCC) in India. Here, we review the existing data, available treatment choices, and future directions in HCC management. An extensive search was conducted through PubMed and MEDLINE for studies published between January 2000 and June 2022 on the epidemiology of HCC in India using the following key words: atezolizumab, BCLC staging, hepatocellular carcinoma, immune checkpoint inhibitors, immunotherapy, and programmed cell death ligand-1, with the filters humans and English language. The most frequent risk factors for the development of HCC in India include nonalcoholic fatty liver disease, hepatitis B virus and hepatitis C virus infection, liver cirrhosis, and alcohol intake. On the basis of new findings, the Barcelona Clinic Liver Cancer (BCLC) Staging Criteria need to be revised. As most cases in India are discovered at a later stage, curative treatments such as surgical resection, ablation, or liver transplantation may not be an option. Clinical trials are underway for a number of immune checkpoint drugs that target cytotoxic T-cell lymphocyte-4 and programmed cell death-1/programmed cell death-ligand 1. In India, phase III trials of atezolizumab in combination with other drugs are underway for the treatment of various malignancies. Renin angiotensin system inhibitors, antivirals, primary hepatocyte transplantation, and bioartificial liver devices are among the future options for the management of HCC. In developing countries like India, HCC is often diagnosed at an advanced stage because of a delay in routine testing or screening. Therefore, developing effective treatment regimens for such stages is critical. Immunotherapy is a promising treatment option that has the potential to increase overall response and survival rate.

Abstract
The oceans are considered as magnificent source of bioactive metabolites, of which marine sponges associated organisms are being the most effective producers of various bioactive molecules. We previously reported that cyclo(-Pro-Tyr) (CPT), a dipeptide from marine sponge Callyspongia fistularis associated Bacillus pumilus AMK1 bacteria for its anti-proliferative activity through down regulating PI3K signaling and inducing mitochondrial mediated apoptosis in HepG2 cells. Further we emphasize to study the role of CPT against hepatocellular carcinoma (HCC) induced by N-diethylnitrosamine (DEN) in male swiss albino mice in vivo. In this study, HCC was induced by the administration of DEN (75 mg/kg b.wt) dissolved in saline once/week for 3 weeks, then 100 mg/kg b.wt for another successive 3 weeks and observed for 18 weeks. CPT (100 mg/kg b.wt) treatment was started after 14 weeks of DEN induction. The obtained results demonstrated that CPT altered DEN induced oxidative stress by decreasing serum SGOT and SGPT followed increment in the antioxidants such as superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase. This was accompanied by decreased accumulation of glycoconjugates and argyophilic nucleolar organizing regions in the treatment groups. Further, CPT significantly reduced the levels of phospho-PI3Kinase p85 and phospho-AKT and upregulation of PTEN compared with DEN induced group. Besides this, decreased expression of Bcl-2 and increased expression of Bax, Caspase 3, and p53 was observed in CPT treated mice. Therefore, the anticancer mechanism of CPT against DEN induced HCC may be associated with the regulation of the PI3K/AKT signaling pathway, which ultimately stimulates apoptosis.

Abstract
BACKGROUND Chronic hepatitis B (CHB) remains a public health burden, with more than 257 million persons living with hepatitis B virus globally. Despite the availability of a safe and efficacious vaccine, access to immunization remains poor. As per current estimates, if Asian countries rely only on immunization to reduce the burden of disease, the timelines for HBV elimination will be extended to 2060-2090, a far cry from the World Health Organization's clarion call for viral hepatitis elimination by 2030. METHODS Currently, all practice guidelines lay stress on immunization, prevention of mother-to-child transmission and treatment of immune active disease or cirrhosis. In this review, we critically examine the data from the Asian cohorts, clinical and public health rationale of early treatment, risk of HCC, and assess the need for revision of guidelines. DISCUSSION Patients in the immune tolerant phase (IT) remain untreated till they meet variable age, transaminase, or fibrosis criteria, are often lost to follow up and continue transmitting the infection. With global migration patterns, immunization programmes alone cannot prevent the complications of HBV like cirrhosis, end-stage liver disease, and hepatocellular carcinoma (HCC). In addition, data from Asian cohorts from Taiwan and Korea suggest that HBV DNA levels are directly associated with increased risk of HCC. Histological evidence of advanced fibrosis or immune reactive T cell subsets in the IT phase also raises doubts about the viability of current guidelines that focus on age, alanine transaminase levels, and liver stiffness as markers of risk of inflammation and fibrosis. Current practice does not take into account the histological subsets with minimal inflammation, HBV genome integration or risk of HCC with high viral loads. CONCLUSION New data from Asian cohorts argue the case of expanding access to care to IT-CHB from public health and clinical perspective.

Abstract
Hepatocellular carcinoma (HCC) is the primary liver cancer that has shown a high incidence and mortality rate worldwide among several types of cancers. A large variety of chemotherapeutic agents employed for the treatment have a limited success rate owing to their limited site-specific drug targeting ability. Thus, there is a demand to develop novel approaches for the treatment of HCC. With advancements in nanotechnology-based drug delivery approaches, the challenges of conventional chemotherapy have been continuously decreasing. Nanomedicines constituted of lipidic and polymeric composites provide a better platform for delivering and opening new pathways for HCC treatment. A score of nanocarriers such as surface-engineered liposomes, nanoparticles, nanotubes, micelles, quantum dots, etc., has been investigated in the treatment of HCC. These nanocarriers are considered to be highly effective clinically for delivering chemotherapeutic drugs with high site-specificity ability and therapeutic efficiency. The present review highlights the current focus on the application of nanocarrier systems using various ligand-based receptor-specific targeting strategies for the treatment and management of HCC. Moreover, the article has also included information on the current clinically approved drug therapy for hepatocellular carcinoma treatment and updates of regulatory requirements for approval of such nanomedicines.

Abstract
Hepatitis B infection (HBV) is one of the most common causes of hepatocellular carcinoma (HCC) worldwide. The age of occurrence, prognosis and incidence vary dramatically depending on the region of the world. This geographic variation is largely dependent on the contrasting incidence of HBV, age of transmission of the virus, the timing of integration into the human genome, and different HBV genotypes, as well as environmental factors. It results in a wide difference in viral interaction with the immune system, genomic modulation and the consequent development of HCC in an individual. In this review, we describe many factors implicated in HCC development, provide insight regarding at-risk populations and explain societal recommendations for HCC surveillance in persons living with HBV in different continents of the world.

Abstract
Liver is the earliest target for AFB1 toxicity in both human and animals. In the last decade, plant derived by-products have been used in animal feed to reduce AFB1 induced toxicity. In the present study we investigated whether the presence of 8% grape seed meal by-product is able to counteract the hepatotoxic effects produced by AFB1 in liver of pig after weaning exposed to the toxin through the contaminated feed for 28 days. Twenty four weaned cross-bred TOPIGS-40 piglets with an average body weight of 9.13±0.03 were allocated to the following experimentally treatments: control diet without AFB1 (normal compound feed for weaned pigs); contaminated diet with 320 mg kg-1 AFB1; GSM diet (compound feed plus 8% grape seed meal) and AFB1+GSM diet (320 mg kg-1 AFB1 contaminated feed plus 8% grape seed meal). Pigs fed AFB1 diet had altered performance, body weight decreasing with 25.1% (b.w.: 17.17 kg for AFB1 vs 22.92 kg for control). Exposure of piglets to AFB1 contaminated diet caused liver oxidative stress as well as liver histological damage, manly characterized by inflammatory infiltrate, fibrosis and parenchyma cells vacuolation when compared to control and GSM meal group. 94.12% of the total analysed genes (34) related to inflammation and immune response was up-regulated. The addition of GSM into the AFB1 diet diminished the gene overexpression and ameliorate histological liver injuries and oxidative stress. The protective effect of GSM diet in diminishing the AFB1 harmful effect was mediated through the decreasing of gene and protein expression of MAPKs and NF-κB signalling overexpressed by AFB1 diet. The inclusion of grape seed by-products in the diet of pigs after weaning might be used as a novel nutritional intervention to reduce aflatoxin toxicity.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common cancer and the third most common cause of cancer mortality worldwide. Infection with hepatitis B virus (HBV) and/or hepatitis C virus (HCV) is the most predominant cause of HCC. Concerns arise for the presence of additional risk factors, as there is still a large proportion of patients without HBV or HCV infection. Previous studies have reported that higher intake of fruits and vegetables and reduced consumption of red/processed meat might play a protective role in HCC etiology, though the nationwide proof is limited. Hence, we studied multiple risk factors including food habit, lifestyle, and clinical implications of HCC patients in Bangladeshi. Demographic, clinical, and biochemical data, as well as data on food habits, were collected in this study. Our results indicated that a high intake of rice (AOR 4.28, 95% CI 1.48 to 14.07, p = 0.011), low intake of fruits (AOR = 4.41 95% CI 1.48-15.46; p = 0.012), leafy vegetables (AOR = 2.80, 95% CI 1.32-6.08; p = 0.008), and fish (AOR = 4.64 95% CI 2.18-10.23; p<0.001) increased the HCC risk. Moreover, a high intake of eggs (AOR = 2.07 95% CI 0.98-4.43; p = 0.058) also showed an increased risk. Roti, non-leafy vegetables, red meat, and tea were found to have no association with HCC risk. This study revealed that food habit patterns and lifestyle may have a profound effect on HCC development among Bangladeshi patients in addition to well established risk factors.

Abstract
Resistance to anticancer agents has been an obstacle to developing therapeutics and reducing medical costs. Whereas sorafenib is used for the treatment of human hepatocellular carcinoma (HCC), resistance limits its efficacy. p62, a multifunctional protein, is overexpressed in several HCC cell lines, such as Huh-1 cells. Phosphorylated p62 (p-p62) inhibits the protein-protein interaction (PPI) between Keap1 and Nrf2, resulting in the Nrf2 overactivation that causes drug resistance. We have found a unique Nrf2 inactivator, named K67, that inhibited the PPI between Keap1 and p-p62 and attenuated sorafenib resistance in Huh-1 cells. Herein, we designed and synthesised novel K67 derivatives by modification of the substituent at the 4-position of the two benzenesulfonyl groups of K67. Although these new derivatives inhibited the Keap1-p-p62 PPI to a level comparable to or weaker than that of K67, the isopropoxy derivative enhanced the sensitivity of Huh-1 cells to sorafenib to a greater extent than K67 without any influence on the viability of Huh-7 cells, which is a non-resistant HCC cell line. The isopropoxy derivative also increased the sensitivity of Huh-1 cells to regorafenib, which suggests that this derivative has the potential to be used as an agent to overcome chemoresistance based on Nrf2 inactivation.

Abstract
INTRODUCTION Liver cirrhosis (LC) is a heterogeneous liver disease, the last stage of liver fibrosis, and the major risk factor for hepatocellular carcinoma (HCC). Our study aimed to evaluate the expression of microRNAs and the endothelial vascular growth factor (VEGFA) gene in LC and HCC. MATERIAL AND METHODS The sample group consisted of 46 tissue samples: 21 of LC, 15 of HCC, and 10 of non-tumoural and non-cirrhotic liver tissue (control group). MiRNAs were chosen based on a mirDIP prediction database as regulators of the VEGFA gene. Gene expression of VEGF and miRNAs was quantified by real-time quantitative polymerase chain reaction. VEGFA protein expression was evaluated by ELISA. RESULTS VEGFA gene expression was significantly overexpressed in LC compared to the control group (p < 0.0001). Hsa-miR-206 (p = 0.0313) and hsa-miR-637 (p = 0.0156) were down-expressed in LC. In HCC, hsa-miR-15b (p = 0.0010), hsa-miR-125b (p = 0.0010), hsa-miR-423-3p (p = 0.0010), hsa-miR-424 (p = 0.0313), hsa-miR-494 (p < 0.0001), hsa-miR-497 (p < 0.0001), hsa-miR-612 (p = 0.0078), hsa-miR-637 (p < 0.0001), and hsa-miR-1255b (p = 0.0156) presented down-expression. CONCLUSIONS Overexpression of VEGFA in LC suggests impairment of angiogenesis in this tissue. The differential expression of microRNAs in LC and HCC observed in our study can lead to the evaluation of possible biomarkers for these diseases.

Abstract
The classification of recurrence and non recurrence of Hepato Cellular carcinoma (HCC) outcome after Radio Frequency Ablation therapy is a critical task. Multiple time series clinical liver cancer dataset is collected from different dataset and time interval. A merging algorithm is used to merge all attributes collected from different sources in multiple time periods. In order to preserve the originality of information, statistical measures of each attribute is calculated and considered them as additional attributes for accurate prediction. However the merged dataset is unbalanced, in which, the number of samples from HCC recurrence class is much smaller than from HCC non recurrence. The feature weighting scheme select optimal features and parameter of classifiers are sequentially obtained from multiple iterations which causes higher computation time. In this paper, an efficient sampling approach is proposed using Inverse Random under Sampling (IRUS) to overcome class imbalance issue. IRUS under sample the majority class which creates a number of distinct partitions with a boundary separated minority and majority class samples. Additionally an optimization approach is proposed using Artificial Plant Optimization (APO) algorithm to select optimal features and parameters of classifiers to improve the effectiveness and efficiency of classification. The optimization approach reduces the number of iteration and computation time for feature selection and parameter selection for classifiers which classify the recurrence and non recurrence of HCC. Classify patients with HCC and without HCC based on optimal features and parameters by Support Vector Machine (SVM) and Random Forest(RF) classifiers. Finally, the experimental results are conducted to prove the effectiveness of the proposed method over existing method in terms of accuracy, specificity, sensitivity and balanced accuracy.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, which in turns accounts for the sixth most common cancer worldwide. Despite being the 6th most common cancer it is the second leading cause of cancer related deaths. HCC typically arises in the background of cirrhosis, however, about 20% of cases can develop in a non-cirrhotic liver. This particular subgroup of HCC generally presents at an advanced stage as surveillance is not performed in a non-cirrhotic liver. HCC in non-cirrhotic patients is clinically silent in its early stages because of lack of symptoms and surveillance imaging; and higher hepatic reserve in this population. Interestingly, F3 fibrosis in non-alcoholic fatty liver disease, hepatitis B virus and hepatitis C virus infections are associated with high risk of developing HCC. Even though considerable progress has been made in the management of this entity, there is a dire need for implementation of surveillance strategies in the patient population at risk, to decrease the disease burden at presentation and improve the prognosis of these patients. This comprehensive review details the epidemiology, risk factors, clinical features, diagnosis and management of HCC in non-cirrhotic patients and provides future directions for research.

Abstract
Hepatitis B virus (HBV) can induce chronic inflammation, cirrhosis, and eventually hepatocellular carcinoma (HCC). Despite evidence suggesting a link between adaptive immunity and HBV-related diseases in humans, the immunopathogenic mechanisms involved are seldom described. Here we show that expression of TIGIT, a promising immune checkpoint in tumor immunotherapy, increases with age on hepatic CD8+ T cells in HBsAg-transgenic (HBs-tg) mice whose adaptive immune system is tolerant to HBsAg. TIGIT blockade or deficiency leads to chronic hepatitis and fibrosis, along with the emergence of functional HBsAg-specific cytotoxic T lymphocytes (CTLs), suggesting adaptive immune tolerance could be broken by TIGIT blockade or deficiency. Importantly, HBsAg vaccination further induces nonresolving inflammation and HCC in a CD8+ T cell-dependent manner in TIGIT-blocked or -deficient HBs-tg mice. Therefore, CD8+ T cells play an important role in adaptive immunity-mediated tumor progression and TIGIT is critical in maintenance of liver tolerance by keeping CTLs in homeostatic balance. Chronic hepatitis B virus (HBV) infection is a risk factor for hepatocellular carcinoma (HCC) and is associated with immune tolerance to HBV. Here the authors show, in a transgenic mouse model, that rescuing T cells function via inhibition of co-inhibitory receptor TIGIT results in HCC development via supporting inflammation.

Abstract
Egg yolk immunoglobulins (IgY), as nutraceutical supplement for therapeutic or prophylactic intervention, have been extensively studied. The effects of IgY on small molecular toxin-induced toxicity in animals are unclear. In the present study, the protection of highly purified and specific anti-AFB1 IgY against AFB1-induced genotoxicity and oxidative damage on the rat liver model were investigated. Our results revealed that AFB1 induced significant oxidative damage markers, as well as AFB1-induced protein expression in antioxidant, pro- and antiapoptosis processes in rat liver. These effects could be significantly inhibited by cogavage with anti-AFB1 IgY in a dose-dependent manner. However, anti-AFB1 IgY did not significantly induce hepatic CAT and SOD1. To explore mechanisms, metabolite experiments were established to evaluate the influence of anti-AFB1 IgY on the absorption of AFB1 in rats. Middle and high doses of anti-AFB1 IgY reduced hepatic AFB1-DNA adducts by 43.3% and 52.9%, AFB1- N7-guanine urinary adducts by 19.6% and 34.4%, and AFB1-albumin adducts by 10.5% and 21.1%, respectively. The feces of high dose anti-AFB1 IgY cogavaged rats contained approximately 2-fold higher AFB1 equivalents at 3-6 h after ingestion than AFB1 group feces, indicating IgY inhibited AFB1 uptake. These results had provided insight that anti-AFB1 IgY could prevent animal organs from damage caused by AFB1 and will be beneficial for the application of detoxification antibody as a supplement in food.

Abstract
OBJECTIVE Hepatocellular carcinoma (HCC) is one of the most lethal human malignancies in China, and the genetic link of hepatocarcinogenesis remains to be defined. Thus, we explored the role of SET and myeloid translocation protein 8, Nervy, and DEAF1 (MYND) domain containing protein 3 (SMYD3) gene polymorphism on risk and prognosis of HCC. METHODS A total of 236 patients with HCC who received treatment in Affiliated Hospital of Jining Medical University for the first time and 230 healthy individuals were enrolled in the study. After DNA extraction for all the subjects, polymerase chain reaction (PCR) was used to amplify and sequence variable numbers of tandem repeat (VNTR) loci of SMYD3 gene. SMYD3 gene was genotyped and its frequency distribution was calculated. Age, education level, income, smoking and drinking history, HCC family history, tumor node metastasis (TNM) staging, maximum tumor diameter, lymph node metastasis (LNM) etc. were investigated. Correlation of SMYD3 gene polymorphism and other risk factors with the occurrence and prognosis of HCC was analyzed. RESULTS The family history of HCC, drinking history, cirrhosis, and HBV or/and HCV infection, SMYD3 VNTR 3/3 were more frequently observed in subjects with HCC. Patients with SMYD3 VNTR 3/3 genotype, drinking-history, family history of HCC, cirrhosis and hepatitis B virus (HBV), TNM staging, maximum tumor diameter, LNM were more vulnerable to HCC. Besides, patients with SMYD3 VNTR 3/3 genotype had lower 2- and 3-year survival rate. The COX regression analysis revealed that drinking history, family history of HCC, SMYD3 VNTR 3/3 genotype, TNM staging, and LNM were all related to the prognosis of HCC. CONCLUSION This study indicates that drinking history, family history of HCC and SMYD3 VNTR 3/3, TNM staging, maximum tumor diameter, LNM might be risk factors for HCC, and SMYD3 VNTR 3/3 might contribute to a lower 2- and 3-year survival rate of patients with HCC.

Abstract
Natural products have been gaining recognition and are becoming a significant part of research in the area of drug development and discovery. Phytochemicals derived from these sources have been comprehensively studied and have displayed a wide range of activities against many fatal diseases including cancer. One such product that has gained recognition from its pharmacological properties and nontoxic nature is embelin, obtained from Embelia ribes. Amid all the vivid pharmacological activities, embelin has gained its prominence in the area of cancer research. Embelin binds to the BIR3 domain of XIAP, preventing the association of XIAP and caspase-9 resulting in the suppression of cell growth, proliferation and migration of various types of cancer cells. Furthermore, embelin modulates anti-apoptotic pathways by suppressing the activity of NF-κB, PI3-kinase/AKT, JAK/STAT pathway - among others. The present review summarizes the various reported effects of embelin on different types of cancer cells and highlights the cellular mechanisms of action.

Abstract
INTRODUCTION Cancer is a complex disease involving neoplasm of abnormal cells leading to development of tumor cells. Gene mutations result in aberrant gene expression, which is the major cause observed in all the cancers. The GLOBOCAN 2012 reported the highest age-standardized rates for cancer of the colorectum followed by stomach, liver, and esophagus, which are gastrointestinal cancers, and the new cases also followed the same order across the globe. Various risk factors are associated with different types of cancer which can be classified as dietary and non-dietary risk factors. The dietary risk factors include diet, alcohol, and nutrient deficiencies, whereas the non-dietary risk factors of cancers are tobacco, lifestyle choices, certain infections, occupational exposures, and environmental factors. PURPOSE The aim of this review is to focus on the dietary and non-dietary risk factors linked to gastrointestinal cancers, which could be beneficial in clinical decision-making.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2017; 97:1910-1915. [PMID: 27539359 DOI: 10.1002/jsfa.7994] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/10/2016] [Revised: 07/27/2016] [Accepted: 08/11/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Aflatoxin B1 (AFB1) is the most prevalent and carcinogenic form of the aflatoxins. In this report, we explored the interaction between AFB1 and oxidised tea polyphenols (OTP). Then, the influence of OTP on the absorption and toxicity of AFB1 in rats was investigated. RESULTS We found that AFB1 can be complexed with OTP, and a transmembrane bidirectional transport experiment verified the absorption of complexed AFB1 (C-AFB1) was inhibited by OTP dramatically (P < 0.001). Animal experiments results showed that the AFB1 plus OTP group had significantly (P < 0.05) decreased AFB1-albumin (AFB1-alb) compared to the AFB1 group at 4 h after ingestion. OTP could significantly (P < 0.01) promote the elimination of AFB1 in faeces. Moreover, the liver injury induced by AFB1 was significantly inhibited by OTP. CONCLUSION Our results demonstrated AFB1 can be complexed with OTP and the absorption of the C-AFB1 is inhibited in rats. Consequently, the liver injury induced by AFB1 can be inhibited by OTP. These results provide insight that consuming OTP-containing products, like fermented Pu-er tea, can protect damage from AFB1, and OTP may be used as a kind of food additive. © 2016 Society of Chemical Industry.

Abstract
The association between serum hepatitis C virus (HCV) load and hepatic injury in HCV-infected patients has been extensively investigated. The present study aimed to investigate the association between HCV load in hepatic parenchyma cells and hepatic injury in HCV-infected patients. A total of 56 HCV-infected patients were included in the present retrospective study. The serum HCV mRNA was determined using quantitative polymerase chain reaction, while the hepatic parenchyma cell volume and HCV mRNA in hepatic parenchyma cells were also determined. Hepatic injury was evaluated on the basis of the severity of inflammation and fibrosis. The results demonstrated that there were evident differences in the mean serum HCV RNA levels and the HCV load/parenchyma cell volume among the various grades of hepatic inflammation (G1-G4) when groups with the least and most inflammation were compared (G1 vs. G4; P<0.05). Significant differences in the HCV load existed between groups divided according to the fibrosis grade; in addition, differences existed between fibrosis grades S1 and S2, and S2 and S4 when comparing serum HCV RNA levels (P<0.05). Similarly, differences existed between every two fibrosis stages (S0 vs. S4, S2 vs. S3, and S2 vs. S4; P<0.05) when viral loads and parenchyma cell volumes were compared (F=2.860, P<0.05). Furthermore, the fibrosis staging was correlated with the viral load/parenchyma cell volume (F=2.670, P<0.05). In conclusion, hepatic fibrosis grade was found to be associated with HCV load in parenchyma cells. The results of the present study demonstrated that the viral load in parenchyma cells is a more appropriate index compared with the serum viral load for evaluating HCV replication in hepatocytes, and may function as an important factor in HCV-infected hepatic injury evaluation.

Abstract
Imaging methods to evaluate hepatic microcirculation (HM) and liver function (LF) by directly monitoring overall liver tissue remain lacking. This study establish imaging methods for LF that combines Laser speckle perfusion imaging (LSPI) and in vivo optical imaging (IVOI) technologies to investigate changes of hepatic microcirculation and reserve function in the animals gavaged with 50% ethanol (15 ml/kg·bw) for a model of acute alcoholic liver injury (ALI), and for evaluation of electroacupuncture (EA) effect. The liver blood perfusion and indocyanine green (ICG) distribution were observe by LSPI and IVOI separately. After EA, the livers were collected to measure the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), thromboxane A (TXA2), prostacyclin (PGI2) and endothelin (ET). The acquisitions of newly established LSPI of liver and ICG in vivo fluorescence imaging (ICG-IVFI), combining the results of other indexes showed: hepatic microcirculation perfusion (HMP) significantly reduced, ICG metabolism reduced, and ALT/AST increased in animal model with acute ALI. EA can reverse these changes. The use of LSPI of liver and ICG-IVFI, which was novel imaging methods for LF established in this study, could display the LF characteristics of ALI and the EA efficacy.

Abstract
Worldwide incidence of hepatocellular carcinoma (HCC) is steadily increasing, highlighting its status as a public health concern, particularly due to its significant association with other comorbidities, such as diabetes. However, nonalcoholic fatty liver disease (NAFLD) has emerged as a primary risk factor, with its own prevalence increasing in recent years, and it has gradually caught up with the historical primary etiological factors of infection with hepatitis B virus and hepatitis C virus, exposure to aflatoxin, or alcohol liver disease. The deeply worrisome aspects of all of these high risk factors, however, are their remarkable presence within populations. Systemic and genetic mechanisms involved in the malignant transformation of liver cells, as well as useful biomarkers of early stage HCC are being investigated. However, the exact mechanisms underlying the interrelation of NAFLD and HCC remain largely unknown. In this review, some of the recent advances in our understanding of liver lipid accumulation are summarized and discussed to provide insights into the relationship between NAFLD and hepatocyte malignant transformation.

Abstract
A method using immobilized affinity chromatography (IAC) was developed to screen for aflatoxin B1 (AFB1)-binding proteins. AFB1 and bovine serum albumin (BSA) coupled protein (BSA-AFB1) was prepared using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride. The resulting coupled compound was immobilized onto PVDF transfer membranes, which were then incubated with total protein from mouse liver. AFB1-binding proteins were eluted, after non-specific washing, by specific elution, and the eluted proteins were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Two candidate AFB1-binding proteins were identified by liquid chromatography-tandem mass spectrometry as the 40S ribosomal protein SA (RPSA) and a putative uncharacterized protein. RPSA and AFB1 interactions were further analyzed by ELISA in vitro and laser confocal immunofluorescence analysis in vivo. The results from ELISA and immunofluorescence showed that RPSA efficiently bound AFB1 in vitro and in vivo. This study's conclusion laid the foundation for further exploration of the role of AFB1-binding proteins in AFB1 toxicology towards hepatocytes and the entry pathway of AFB1 into hepatocytes.

Abstract
AIM: To achieve a better understanding of the molecular mechanisms of microRNA expression changes involved in hepatocellular carcinoma.
METHODS: In this research process, patients were not treated with antivirals, immunosuppressants or immunomodulators for at least 6 mo before collecting serum. The study population was composed of 35 outpatient hepatitis B virus (HBV) cases and 12 healthy control cases from the Affiliated Hospital of Inner Mongolia Medical University (Inner Mongolia, China) from July 2013 to April 2014. The 35 HBV cases were divided into two groups: a hepatocirrhosis group with 20 cases and a liver cancer group with 15 cases. All 35 cases carried HBsAg. The diagnostic criteria followed the European Association for the Study of the Liver 2012 (EASL2012) standards. MicroRNA (miRNA) was extracted from a control group of patients, a group with hepatocirrhosis and a group with liver cancer and its quality was analyzed using the human V2 microRNA expression beadchip. Cluster analysis and a radar chart were then applied to the miRNA changes.
RESULTS: The miRNA-qualified rate of human serum samples was 93%. The concentration of a single sample was > 200 ng/μL and the volume was > 5 μL. All miRNA serum samples were uncontaminated by the genome. The Mann-Whitney test showed significant differences in miRNA between each group, with a detection P-value of < 0.05. Illumina software was set up with Diff Score set to ± 13, meaning that P = 0.001.There were significant changes in miRNA expression between the three groups. miRNA-183 was the most up-regulated, followed by miRNA-373. miRNA-129 and miRNA-188 were both strongly down-regulated and miRNA-378 was down-regulated a small amount. The liver cancer group had greater changes, which indicated that changes in miRNA expression levels were caused by hepatocirrhosis. The liver cancer disease course then further increased these changes. In the pentagon created by these five miRNAs, three groups showed significant deviation. The liver cancer group had a bigger deviation trend. The chart indicated that miRNA expression changes occurred in the hepatocirrhosis group, which increased in the liver cancer disease course and were irreversible.
CONCLUSION: There was a significant relationship between the irreversible up-regulation of miRNA-183/373 and down-regulation of miRNA-129/188/378 and incidences of hepatocirrhosis and liver cancer.
