Abstract
This study examined the effect of gold nanoparticles (AuNPs) on doxorubicin (DOX)-induced liver damage and steatosis in rats and tested its effect mechanism. Wistar male rats were divided into four groups (each of eight rats) as control, AuNPs (50 µL of 10 nm), DOX (15 mg/kg; 3 mg/kg/week), and DOX + AuNPs-treated rats. DOX is known to induce fasting hyperglycemia and hyperinsulinemia in treated rats. Individual treatment of both DOX and AuNPs also promoted liver damage, increased circulatory levels of ALT and AST, and stimulated serum and liver levels of TGs, CHOL, LDL-c, and FFAs. They also stimulated MDA, TNF-α, and IL-6, reduced GSH, SOD, HO-1, and CAT, upregulated mRNA levels of Bax and caspases-3 and -8 and downregulated mRNA levels of Bcl2 in the livers of rats. However, while DOX alone reduced hepatic levels of PPARα, both AuNPs and DOX stimulated mRNA levels of SREBP1, reduced the mRNA, cytoplasmic and nuclear levels of Nrf2, and increased mRNA, cytoplasmic, and nuclear levels of NF-κB. The liver damage and the alterations in all these parameters were significantly more profound when both AuNPs and DOX were administered together. In conclusion, AuNPs exaggerate liver damage, hyperlipidemia, and hepatic steatosis in DOX-treated rats by activating SREBP1 and NF-κB and suppressing the Nrf2/antioxidant axis.

Abstract
Abstract
Background
Hepatitis C virus (HCV) infection is a significant risk factor for cirrhosis and hepatocellular carcinoma (HCC) that carry a high mortality. The study aims to investigate the effect of tumour necrosis factor (TNF)-α and interleukin (IL)-10 polymorphisms on risk and pattern of HCC in patients with HCV-related cirrhosis.
Results
The mean age of the HCC group was 56.21 ± 4.62 years and 54.27 ± 7.63 years for the cirrhotic group. The GG genotype of TNF-ɑ and TT genotype of IL-10 showed a higher incidence of HCC in comparison to the cirrhotic group with P = 0.01 and 0.004. On the calculation of the aggressiveness index (AgI), the TT haplotype was significantly associated with more aggressive tumours in contrast to the other haplotypes with P < 0.001. There is a significant association of portal vein thrombosis, ascites and high AgI with the GG haplotype in contrast to the other haplotypes with P = 0.002, 0.029 and < 0.001, respectively, as regards TNF-α. High AgI (C) was associated with the TT haplotype of IL-10 and GG haplotype of TNF-ɑ.
Conclusion
Our data bring an essential association of IL-10 and TNF polymorphism with the occurrence of HCC in patients with HCV-related liver cirrhosis. The GG haplotype of TNF-ɑ and TT/AT haplotype of IL-10 are associated with the more aggressive pattern of HCC, so those patients must be treated as early as possible.

Abstract
Cancer is recognized as one of the most prevalent contributors to mortality in several nations and it remains one of the common health issues globally. In particular, hepatocellular carcinoma (HCC) has become a public health problem along with the increase of hepatitis B (HBV) and hepatitis C (HCV) virus infections. Based on this fact, our study goaled to synthesize newly hybrid drugs containing heterocyclic rings incorporated to steroid moiety and to examine the potential antitumor activity of the newly designed heterosteroid derivatives against HCC induced in animal model. Several heterocyclic steroids were synthesized 2-7 and confirmed via the analytical and spectral data (IR, 1H NMR13C NMR and Mass spectroscopy). Compounds 3, 4, and 5 were chosen to be investigated as anticancer agents in HCC rat model by means of validated biomarkers (alfa –fetoprotein, endoglin, lipocali-2 and heat shock protein-70). Following administration of compounds 3, 4 or 5, availability of the active tumor marker molecules was significantly dropped and a substantial decrease of the angiogenic and inflammatory mediators was also evident. These findings were supported by the histological examination of liver tissue. Taken together, this study indicates the potential anticancer activity of the newly synthesized heterosteroid derivatives against HCC in vivo. The antitumor activity of these compounds was likely attributable to modulating some signal transduction pathways involved in tumorigenesis, angiogenesis and inflammation.

Front Pharmacol 2019; 10:1030. [PMID: 31572199 PMCID: PMC6753638 DOI: 10.3389/fphar.2019.01030] [Citation(s) in RCA: 83] [Impact Index Per Article: 16.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Accepted: 08/12/2019] [Indexed: 12/12/2022] Open
Abstract
Doxorubicin (Dox), an antitumor antibiotic, has therapeutic effects on many kinds of tumors. However, Dox can produce some serious side effects that limit its clinical application. Thus, exploration of effective drug targets or active lead compounds against Dox-induced organ damage is necessary. Dioscin, one natural product, has potent effects against Dox-induced renal injury and cardiotoxicity. However, the effects of dioscin on Dox-induced hepatotoxicity have not been reported. In this study, the results showed that dioscin significantly ameliorated Dox-induced cell injury, reduced reactive oxygen species (ROS) level, and suppressed cell apoptosis in alpha mouse liver 12 (AML-12) cells caused by Dox. In vivo, dioscin evidently decreased the levels of alanine transaminase (ALT), aspartate transaminase (AST), malondialdehyde (MDA); increased the levels of superoxide dismutase (SOD), glutathione (GSH), and glutathione peroxidase (GSH-Px); and alleviated liver injury. Mechanism study showed that dioscin remarkably up-regulated the expression levels of silent information regulator 1 (Sirt1) and heme oxygenase-1 (HO-1) via increase of the nuclear translocation of NF-E2-related factor 2 (Nrf2) and suppressed the expression levels of forkhead box protein O1 (FOXO1) and kelch-like ECH-associated protein-1 (Keap1) to inhibit oxidative stress. Furthermore, dioscin obviously decreased the nuclear translocation of nuclear factor κB (NF-κB) and the mRNA levels of tumor necrosis factor alpha (TNF-α), interleukin 1β (IL-1β), and interleukin 6 (IL-6) to suppress inflammation. Meanwhile, dioscin significantly regulated tumor suppressor P53 (P53) expression level and BCL-2-associated X (BAX)/BCL-2 apoptosis regulator (BCL-2) ratio to inhibit cell apoptosis. These results were further validated by knockdown of Sirt1 using siRNA silencing in AML-12 cells, which confirmed that the target of dioscin against Dox-induced hepatotoxicity was Sirt1/FOXO1/NF-κB signal. In short, our findings showed that dioscin exhibited protective effects against Dox-induced liver damage via suppression of oxidative stress, inflammation, and apoptosis, which should be developed as one new candidate for the prevention of Dox-induced liver injury in the future.

Abstract
Hepatocellular carcinoma (HCC) is an inflammation-related disease. Tumor necrosis factor alpha (TNF-α) is an important inflammatory factor and it has been confirmed to promote tumor growth and poor prognosis of HCC. Hepatic progenitor cells (HPCs) are thought to play an important role in liver injury and repair, as well as tumorigenesis. Chronic inflammation influences HPCs activation as well as differentiation. However, the mechanism is still unclear. In our study, the rat liver cancer model was constructed by DEN treatment, TNFR2-Fc fusion protein variant (TNFR2-FcV) and TNF-α-/- rats were used to detect the role of TNF-α in liver injury and tumorigenesis. And the effect of TNF-α on HPCs activation and proliferation was investigated, and the specific molecular mechanism was explored. We found that TNF-α inhibition and deletion could reduce tumor incidence but shorten survival time by increasing apoptosis and decreasing proliferation of hepatocytes. Further analysis indicated that TNF-α knochdown cloud inhibit HPCs activation and proliferation through TNFR2/STAT3 signaling pathway. And clinically TNF-α expression was correlated to HPCs activation and HCC recurrences. Our work suggested that TNF-α played a key role in liver injury and tumorigenesis.

Abstract
Background Exosomes or extracellular vesicles have the potential as a diagnostic marker for various diseases including cancer. In order to identify novel exosomal markers for prostate cancer (PC), we performed proteomic analysis of exosomes isolated from PC cell lines and examined the usefulness of the marker in patients. Methods Exosomes isolated by differential centrifugation from the culture medium of androgen-dependent LNCaP prostate cancer cell line and its sublines of partially androgen-independent C4, androgen-independent C4–2 and bone metastatic C4–2B were subjected to iTRAQ-based proteomic analysis. Exosomes were also isolated by immunocapture and separated by size exclusion chromatography and density gradient centrifugation. Protein expression was determined by Western blot analysis. GGT activity was measured using a fluorescent probe, γ-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG). Immunohistochemical analysis of tissues was performed using anti-GGT1 antibody. Results Among proteins upregulated in C4–2 and C4–2B cells than in LNCaP cells, we focused on gamma-glutamyltransferase 1 (GGT1), a cell-surface enzyme that regulates the catabolism of extracellular glutathione. The levels of both GGT1 large and small subunits were elevated in exosomes isolated from C4–2 and C4–2B cells by differential centrifugation and by immunocapture with anti-CD9 or -prostate-specific membrane antigen (PSMA) antibody. In cell lysates and exosomes, GGT1 expression correlated with GGT activity. Size exclusion chromatography of human serum demonstrated the presence of GGT activity and GGT1 subunits in fractions positive for CD9. Density gradient centrifugation revealed the co-presence of GGT1 subunits with CD9 in exosomes isolated by differential centrifugation from human serum. Since GGT activity correlated with GGT1 expression in serum exosomes isolated by differential centrifugation, we measured serum exosomal GGT activity in patients. Unexpectedly, we found that serum exosomal GGT activity was significantly higher in PC patients than in benign prostatic hyperplasia (BPH) patients. In support of this finding, immunohistochemical analysis showed increased GGT1 expression in PC tissues compared with BPH tissues. Conclusions Our results suggest that serum exosomal GGT activity could be a useful biomarker for PC.

Abstract
Doxorubicin (DOX) remains the most effective anticancer agent which is widely used in several adult and pediatric cancers, but its application is limited for its cardiotoxicity and hepatotoxicity. Hydrogen, as a selective antioxidant, is a promising potential therapeutic option for many diseases. In this study, we found that intraperitoneal injection of hydrogen-rich saline (H2 saline) ameliorated the mortality, cardiac dysfunction, and histopathological changes caused by DOX in rats. Meanwhile, serum brain natriuretic peptide (BNP), aspartate transaminase (AST), alanine transaminase (ALT), albumin (ALB), tissue reactive oxygen species (ROS), and malondialdehyde (MDA) levels were also attenuated after H2 saline treatment. What is more, we further demonstrated that H2 saline treatment could inhibit cardiac and hepatic inflammation and apoptosis relative proteins expressions by western blotting test. In conclusion, our results revealed a protective effect of H2 saline on DOX-induced cardiotoxicity and hepatotoxicity in rats by inhibiting inflammation and apoptosis.

Abstract
The present study was undertaken to investigate the association between Hepatitis B Virus (HBV) infection and polymorphisms of tumour necrosis factor alpha TNF-α -308 G>A, TNF-α -238 G>A and TNF RII VNTR (p75) gene promoter in a Tunisian population. Blood samples were collected from 100 Tunisian patients with HBV infection, 45 with Chronic Hepatitis (CH), 36 with Liver Cirrhosis (LC), 15 with Hepatocellular Carcinoma (HCC) and 200 healthy individuals of similar ethnicity. Genomic DNA was extracted from peripheral blood leukocytes. Genotyping of the analysed polymorphisms was performed using Amplified Refractory Mutation System-Polymerase Chain Reaction (ARMS-PCR), Restriction Fragment Length Polymorphism (RFLP) and Variable Number Tandem Repeat PCR (PCR-VNTR). The variant homozygotes -308 GG were associated with 50% decreased risk of HBV chronic infection (GG vs AA+GA; p=0.010; OR=0.50; 95%CI=0.29-0.85). However, the carriers of minor allele -308 A have higher risk (1.5 times) to develop a chronic infection than other patients (p=0.027; OR=1.46; 95%CI=1.04-2.06). The minor allele of -238 polymorphism was positively associated with virus resistance and the development of chronic infection (p=0.043; OR=1.42; 95%CI =1.01 1.99). The distribution of -308, -238 and TNF RII VNTR (p75) among the three groups differed significantly. For HCC groups, there were statistically significant differences in allele distribution in -308, -238 respectively in which A allele remains a risk factor for HBV evolution to HCC (p=0.008 and p=0.026). Haplotype analysis revealed that TNF-α (-308A; -238A) was significantly associated to HBV chronic infection and moreover to disease aggravation to HCC stage. Our findings imply that variations in the genes governing the levels of constitutive and inducible TNF-α and TNF RII might be an important risk factor, which could explain the variable outcomes of HBV infection.

Abstract
BACKGROUND HCC patients are heterogeneous in terms of both tumor and liver factors. Alpha-fetoprotein (AFP) is an important prognostic tumor marker for those patients with elevated AFP levels. AIMS To examine the differences in HCC patients with high or low AFP levels in blood and evaluate the prognostic parameters in low AFP patients. METHODS A cohort of 2,440 HCC patients from 11 Italian medical centers was studied. AFP-positive patients were compared to AFP-negative ones, and the blood and tumor parameters of AFP-negative patients were examined. RESULTS Low blood AFP levels were found in 58% of the total cohort, in 64% of patients with small HCCs, and in 51% of patients with large HCCs. In patients with large tumors, platelet and gamma glutamyl transpeptidase (GGTP) levels, tumor multifocality and portal vein thrombosis (PVT) incidence were all greater than in patients with small tumors, regardless of AFP status. Patients with higher AFP levels had worse survival rates than those with low AFP in each tumor size group. In patients with small tumors, the elevated AFP was associated with significantly increased PVT and worse survival. In patients with large tumors, the elevated AFP was associated with significantly higher GGTP, ALKP, and bilirubin levels, as well as with increased PVT and multifocality, and worse survival. Low-AFP patients with high GGTP levels had worse survival than patients with low GGTP levels. CONCLUSION Patients with low AFP were the majority in this cohort, and patients with elevated GGTP had worse prognosis than those with low GGTP. GGTP may be a useful tumor and prognosis marker in low-AFP patients. AFP-negative patients are important to identify due to their enhanced survival.

Curr Ther Res Clin Exp 2014; 76:70-5. [PMID: 25352937 PMCID: PMC4209508 DOI: 10.1016/j.curtheres.2014.04.001] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/12/2014] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Tumor necrosis factor-α (TNF-α) has been suggested to play a very important role in the development and progression of hepatocellular carcinoma (HCC). Many studies have identified the associations of TNF-α-308 and -238 polymorphisms with HCC risk, but the results remain controversial. AIM We conducted this meta-analysis to evaluate the associations between TNF-α-308 and -238 polymorphisms and HCC susceptibility. METHODS PubMed, Embase, and China National Knowledge Infrastructure electronic databases were searched for all articles on associations between TNF-α-308 and -238 polymorphisms and HCC risk in Asians through September 30, 2013. Odds ratios (ORs) and their 95% CIs were calculated to assess the strength of this association. RESULTS A total of 17 case-control studies were identified in our meta-analysis. For the TNF-α-308 G/A polymorphism, 14 studies containing 3154 cases and 3767 controls were included. Overall, the frequency of the A allele was higher in patients with HCC than in the healthy controls (10.2% vs 7.5%), and the A allele and allele carrier were significantly associated with increased risk of HCC in a random effects model (A vs G: OR = 1.57; 95% CI, 1.22-2.01; P = 0.0004; AA + AG vs GG: OR = 1.62; 95% CI, 1.18-2.22; P = 0.003). For the TNF-α-238 polymorphism, 10 research articles were identified. No association was found between the TNF-α-238 G/A polymorphism and risk of HCC in any genetic models (P > 0.05). The sensitivity analysis further strengthened the overall correlations. CONCLUSIONS Our meta-analysis proved that the TNF-α-308 G/A polymorphism is associated with increased susceptibility to HCC. However, the TNF-α-238 G/A polymorphism is not significantly associated with risk of HCC in Asian populations. Further studies with large sample sizes are needed to confirm these associations among other populations.

Abstract
BACKGROUND The prevalence of non-B or non-C hepatocellular carcinoma (NBNC-HCC) has been increasing all over the world. Advanced glycation end products (AGE) play a role in the pathogenesis of alcoholic liver injury or nonalcoholic steatohepatitis (NASH). METHODS We examined here whether serum levels of AGE were elevated in NBNC-HCC patients compared with NASH subjects without HCC and investigated which anthropometric and clinical variables were independent determinants of AGE. RESULTS Ninety NBNC-HCC, 56 NASH, and 27 control subjects underwent a complete history and physical examination, determination of blood chemistries, including AGE levels. Serum levels of AGE were significantly higher in NBNC-HCC patients compared with NASH and control subjects [9.1 ± 2.7, 5.2 ± 1.7, 3.5 ± 1.2 (U/ml), respectively, P < 0.05]. Univariate analysis showed that AGE levels were associated with male (P < 0.05), age (P < 0.01), aspartate aminotransferase (P < 0.05), γ-glutamyl transpeptidase (GGT) (P < 0.01), HDL-cholesterol (inversely, P < 0.01), fasting plasma glucose (P < 0.01), and HbA1c (P < 0.05). By the use of multiple stepwise regression analysis, age, GGT, and HDL-cholesterol (inversely) remained significant and were independently related to AGE levels (R(2) = 0.406). CONCLUSION The present results suggest that AGE might be involved in the pathogenesis of NBNC-HCC, thereby being a biomarker that could discriminate NBNC-HCC from NASH.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is one of the most common and aggressive cancers worldwide, and the pathogenesis is complicated at present. There iare few effective therapeutic measures, and novel therapeutic strategies are urgently required to improve clinical outcome. Ginkgo biloba extract (EGb) is reported to have an anti-cancer activity. OBJECTIVES To explore the effect of EGb on expressions of cyclooxygenase-2 (Cox-2) and glutathione S-transferase Pi (GST-Pi) in the pathogenesis of HCC. METHODS 120 Wistar rats were divided into three groups at random: normal control group (control group), HCC risk group without treatment (HCC risk group), HCC risk group treated with EGb (EGb group); n=40, respectively. The HCC risk in rat was induced by aflatoxin B1 injection. At the end of 13-week, 33-week, 53-week and 73-week, 10 rats in each group were killed and the relevant samples were collected. RESULTS The mRNA and protein expressions of Cox-2 and GST-Pi were measured by real-time reverse transcription polymerase chain reaction, immunohistochemical analysis and western-blot. When compared with those in the control group in 73-week, the mRNA and protein expressions of GST-Pi in EGb group were weaker than those in HCC risk group in 73-week. However, the mRNA and protein expressions of Cox-2 in HCC risk group were increased than that of control group, and there was no statistical difference for mRNA and protein expressions of Cox-2 between HCC risk group and EGb group. CONCLUSION EGb can regulate the expression of GST-Pi, but it does not seem to have an effect on Cox-2 expression in the liver of HCC risk rats.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common and rapidly fatal malignancies worldwide with a multifactorial, multistep, complex process and poor prognosis. Its early diagnosis and metastasis monitoring are of the utmost importance. Hepatoma tissues synthesize various tumor-related proteins, genes, enzymes, microRNA, etc. and then secrete into the blood. Detections of circulating biomarkers are useful to find tumor at an early stage or monitor metastasis after postoperative treatment. This paper summarizes recent studies of specific biomarkers at early diagnosis or in monitoring metastasis or postoperative recurrence of HCC.

Abstract
A number of studies have demonstrated that inflammation plays a role in doxorubicin (DOX)-induced cardiotoxicity. However, the molecular mechanism by which DOX induces cardiac inflammation has yet to be fully elucidated. The present study aimed to investigate the role of the p38 mitogen-activated protein kinase (MAPK)/nuclear factor-κB (NF-κB) pathway in DOX-induced inflammation and cytotoxicity. The results of our study demonstrated that the exposure of H9c2 cardiac cells to DOX reduced cell viability and stimulated an inflammatory response, as demonstrated by an increase in the levels of interleukin-1β (IL-1β) and IL-6, as well as tumor necrosis factor-α (TNF-α) production. Notably, DOX exposure induced the overexpression of phosphorylated p38 MAPK and phosphorylation of the NF-κB p65 subunit, which was markedly inhibited by SB203580, a specific inhibitor of p38 MAPK. The inhibition of NF-κB by pyrrolidine dithiocarbamate (PDTC), a selective inhibitor of NF-κB, significantly ameliorated DOX-induced inflammation, leading to a decrease in the levels of IL-1β and IL-6, as well as TNF-α production in H9c2 cells. The pretreatment of H9c2 cells with either SB203580 or PDTC before exposure to DOX significantly attenuated DOX-induced cytotoxicity. In conclusion, our study provides novel data demonstrating that the p38 MAPK/NF-κB pathway is important in the induction of DOX-induced inflammation and cytotoxicity in H9c2 cardiac myocytes.

Abstract
SIGNIFICANCE Fatigue is one of the most common symptoms of cancer and its treatment, manifested in the clinic through weakness and exercise intolerance. These side effects not only compromise patient's quality of life (QOL), but also diminish physical activity, resulting in limited treatment and increased morbidity. RECENT ADVANCES Oxidative stress, mediated by cancer or chemotherapeutic agents, is an underlying mechanism of the drug-induced toxicity. Nontargeted tissues, such as striated muscle, are severely affected by oxidative stress during chemotherapy, leading to toxicity and dysfunction. CRITICAL ISSUES These findings highlight the importance of investigating clinically applicable interventions to alleviate the debilitating side effects. This article discusses the clinically available chemotherapy drugs that cause fatigue and oxidative stress in cancer patients, with an in-depth focus on the anthracycline doxorubicin. Doxorubicin, an effective anticancer drug, is a primary example of how chemotherapeutic agents disrupt striated muscle function through oxidative stress. FUTURE DIRECTIONS Further research investigating antioxidants could provide relief for cancer patients from debilitating muscle weakness, leading to improved quality of life.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF₁₆₅) is stored, transported and released by platelets. Platelet functional abnormalities have been described in patients with hepatocellular carcinoma (HCC). Thus, this study was designed to investigate the behavior of VEGF₁₆₅ with respect to platelet activation in HCC. METHODS Plasma and serum VEGF₁₆₅ and plasma sP-selectin levels were analyzed in patients with HCC (n=70) or cirrhosis (n=45) and control subjects (n=70). Given the thrombocytopenia that characterizes both HCC and cirrhotic patients, plasma VEGF₁₆₅ and sP-selectin as well as serum VEGF (plt-VEGF₁₆₅-load) levels were normalized by platelet counts. RESULTS Median concentrations of plasma VEGF₁₆₅/platelet (p=0.002) and sP-selectin/platelet (p<0.0001) were higher in HCC or cirrhotic patients compared to controls. Moreover, sP-selectin/platelet was the only independent variable predictive of plasma VEGF₁₆₅/platelet at multivariate analysis (p<0.0001). Conversely, plt-VEGF₁₆₅-load correlated with tumor diameter (p<0.05) but not with sP-selectin/platelet and was an independent predictor for 5year overall survival (p=0.012). CONCLUSIONS The results obtained are suggestive for VEGF₁₆₅ release by tumor in HCC. It is plt-VEGF₁₆₅-load, but not plasma VEGF₁₆₅ or serum VEGF₁₆₅ that is an independent predictor for overall survival of HCC patients.

Abstract
Doxorubicin, a common chemotherapeutic agent, causes respiratory muscle weakness in both patients and rodents. Tumor necrosis factor-α (TNF), a proinflammatory cytokine that depresses diaphragm force, is elevated following doxorubicin chemotherapy. TNF-induced diaphragm weakness is mediated through TNF type 1 receptor (TNFR1). These findings lead us to hypothesize that TNF/TNFR1 signaling mediates doxorubicin-induced diaphragm muscle weakness. We tested this hypothesis by treating C57BL/6 mice with a clinical dose of doxorubicin (20 mg/kg) via intravenous injection. Three days later, we measured contractile properties of muscle fiber bundles isolated from the diaphragm. We tested the involvement of TNF/TNFR1 signaling using pharmaceutical and genetic interventions. Etanercept, a soluble TNF receptor, and TNFR1 deficiency protected against the depression in diaphragm-specific force caused by doxorubicin. Doxorubicin stimulated an increase in TNFR1 mRNA and protein (P < 0.05) in the diaphragm, along with colocalization of TNFR1 to the plasma membrane. These results suggest that doxorubicin increases diaphragm sensitivity to TNF by upregulating TNFR1, thereby causing respiratory muscle weakness.

Abstract
Hepatitis C virus (HCV) infection causes chronic hepatitis, which gradually progresses to liver cirrhosis and subsequently to hepatocellular carcinoma (HCC). Angiogenesis plays a major role in chronic inflammation and may have prognostic value in disease progression. This study was designed to evaluate vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and tumor necrosis factor-alpha (TNF-alpha) as prognostic factors of disease progression in Egyptian patients with different stages of HCV-related cirrhosis and HCC. VEGF, PDGF, and TNF-alpha were measured using enzyme-linked immunosorbent assay (ELISA) in 82 HCV-infected patients (20 mild, 20 moderate, and 20 severe cirrhosis patients, and 22 HCC patients), and 20 healthy controls. Our results showed comparable increases in VEGF and PDGF levels in those with increasing clinical stages of disease, with maximal production seen in HCC patients. A gradual elevation of TNF-alpha levels was seen also in HCV-infected patients at different stages of disease and HCC. A statistically significantly positive correlation between serum levels of VEGF, PDGF, and TNF-alpha, and grade of disease was recorded. Thus assessment of these parameters in those with different stages of disease may be helpful in choosing the best treatment strategy, and indicate that anti-angiogenic therapy may be useful.

Abstract
Nucling is a stress-inducible protein associated with apoptosomes. The cytochrome c-triggered formation of apoptosomes represents a key-initiating event in apoptosis. We have recently reported that Nucling regulates the apoptotic pathway by controlling the activation of NF-kappaB as well. Here we show that hepatocellular carcinoma (HCC) arising spontaneously against a background of hepatitis occurred more frequently in Nucling-knockout (KO) mice than wild-type (WT) mice. Biochemical serum testing revealed potential liver dysfunction with hypercholesterolemia in Nucling-KO males. In the background of Nucling-KO mice, we observed the up-regulation of TNFalpha, spontaneous NF-kappaB-activation and the induction of galectin-3 expression in liver. In addition, we observed a decrease in the number of Kupffer cells (KCs) in the KO mice. KCs are important for the hepatic immune system, acting as phagocytes or antigen-presenting cells (APCs). We found that KCs in Nucling-KO mice were apoptotic possibly through the up-regulation of TNFalpha. These observations indicate that Nucling is important for the regulation of NF-kappaB signals in liver. We propose that Nucling deficiency could be a powerful tool to reveal the NF-kappaB-related molecular networks leading to hepatitis and HCC development.

Abstract
We conducted a case-control study to assess the roles of tumor necrosis factor (TNF)-alpha polymorphisms, substance use habits, and chronic hepatitis B virus (HBV)/hepatitis C virus (HCV) infection on the risk for hepatocellular carcinoma (HCC). We enrolled 200 pairs of sex- and age-matched patients with HCC and unrelated healthy controls. TNF-alpha polymorphisms were detected with polymerase chain reaction and direct sequencing. Serum hepatitis B surface antigen (HBsAg) and antibodies to HCV (anti-HCV) were detected. We used a structured questionnaire to obtain information about substance use habits.Multivariate analysis indicated that TNF308.2 allele (odds ratio [OR], 3.23; p = 0.011), habitual betel quid chewing (OR, 3.70; p = 0.011), HBsAg (OR, 23.62; p = 0.0001), and anti-HCV (OR, 38.73; p = 0.0001) were independent risk factors for HCC. Having at least 2 substance use habits was associated with risk for HCC. The more substance use habits, the higher the OR for HCC (p(for trend) = 0.0001). There were additive interactions among TNF308.2 allele, substance use habits, and chronic HBV/HCV infection. Multivariate analysis indicated that TNF308.2 allele (p = 0.001), cigarette smoking (p = 0.0001), and alcohol drinking (p = 0.0001) were independent risk factors for habitual betel quid chewing. Moreover, patients harboring the TNF308.2 allele and/or those with habits of substance use had low serum albumin concentration and platelet count (each p = 0.0001). In conclusion, there are independent and additive interactive effects among the TNF308.2 allele, substance use habits, and chronic HBV/HCV infection on the risk for HCC. Substance use habits or carrying the TNF308.2 allele correlates with disease severity and hepatic fibrosis, which may contribute to higher risks for HCC.

Abstract
Abnormal expression of total γ-glutamyl transferase (GGT, EC 2.3.2.2) activity can be found in patients with different liver diseases and extrahepatic tumors. Circulating GGT from hepatocellular carcinoma (HCC) patients can be divided into different isoforms (Ⅰ, Ⅰ', Ⅱ, Ⅱ', β, δ, ε, φA, ⅦB, φC, γA, γB) by using PAGE. Some of these isoforms (Ⅰ', Ⅱ and Ⅱ', and hepatoma-specific GGT, HS-GGT) can be detected in sera of HCC patients. Hepatic GGT gene expression may be closely related to the development of HCC. The human cDNA sequences from fetal liver, placenta and HepG2 cells (H) were investigated. The genotype H was predominant in cancerous tissues of HCC. Both HS-GGT and genotype H were confirmed as useful specific HCC markers, with higher specificity and sensitivity, and their analysis may be useful for HCC diagnosis and differentiation.

Abstract
BACKGROUND/AIMS Host genetic factor and hepatic fibrosis may predispose to risk for hepatocellular carcinoma (HCC). This study aimed to assess the association between tumor necrosis factor (TNF) alpha polymorphism and hepatic fibrosis, and risk for HCC. METHODS One hundred eight pairs of gender-matched and age-matched patients with HCC and unrelated healthy controls were genotyped for TNF308.2 and TNF238.2 alleles with polymerase chain reaction and direct sequencing. RESULTS The frequency of TNF308.1/TNF308.2 genotype in cases was higher than that in controls [odds ratio (OR) = 4.37]. Multivariate analysis indicated that TNF308.2 allele (OR = 3.23), hepatitis B surface antigen (OR = 17.17), and antibodies to hepatitis C virus (OR = 45.52) were independent risk factors for HCC. Surrogate markers for significant fibrosis implied that cases with the TNF308.2 allele have more advanced liver fibrosis. Moreover, multivariate analysis indicated that cirrhosis with Child-Pugh grade C, low serum albumin, and low platelet count were independent risk factors for carrying the TNF308.2 allele. CONCLUSIONS TNF308.2 allele carriage and chronic hepatitis B virus/hepatitis C virus infection are independent risk factors for HCC. Carriage of the TNF308.2 allele correlates with disease severity and hepatic fibrosis, which may contribute to a higher risk for HCC.
