Abstract
This study was designed to evaluate the potential protective impact of estrogen and estrogen receptor against diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in rats. The levels of liver injury serum biomarkers, liver content of interleukin-6 (IL-6), relative liver weight and distortion of liver histological pictures were significantly increased in ovariectomized (OVX) rats and SHAM rats that received DEN alone and were further exaggerated when DEN was combined with fulvestrant (F) compared to non-DEN treated rats. The OVX rats showed higher insults than SHAM rats. The tapering impact on these parameters was clear in OVX rats that received estradiol benzoate (EB), silymarin (S) or orlistat (ORS). The immunohistochemistry and/or Western blot analysis of liver tissues showed a prominent increase in fatty acid synthase (FASN) and cluster of differentiation 36 (CD36) expressions in OVX and SHAM rats who received DEN and/ or F compared to SHAM rats. In contrast to S, treatment of OVX rats with EB mitigated DEN-induced expression of FASN and CD36 in liver tissue, while ORS improved DEN-induced expression of FASN. In conclusion, the protective effect against HCC was mediated via estrogen receptor alpha (ER-α) which abrogates its downstream genes involved in lipid metabolism namely FASN and CD36 depriving the tumor from survival vital energy source. In addition, ORS induced similar mitigating effect against DEN-induced HCC which could be attributed to FASN inhibition and anti-inflammatory effect. Furthermore, S alleviated DEN-induced HCC, independent of its estrogenic effect.

Abstract
Hepatitis B infection affects millions of people globally, partly due to its high degree of transmissibility and asymptomatic nature. This study was aimed at identifying prevailing epidemiological factors associated with HBV infection and testing uptake in the South West region of Cameroon. This hospital-based case-control study enrolled HBV infected participants and "healthy" controls ≥18 years old. Venous blood collected from participants was used to conduct HBV panel test (HBsAg, anti-HBs, HBeAg, anti-HBe, anti-HBc). Data on demographic and behavioral risk factors as well as reasons for taking the HBV test for the first time were collected using a questionnaire. A total of 424 participants were enrolled (212 "healthy" controls and 212 HBV infected cases). Male sex (odds ratio [OR] = 2.08, p = 0.010), ≤ secondary education level (OR = 4.83, p<0.001), low-income level (OR = 3.79, p<0.001), rural settlement (OR = 2.17, p = 0.031), history of sexually transmitted infections (STI) (OR = 4.24, p<0.001) and ignorance of sexual partners HBsAg status (OR = 2.70, p = 0.003) all had an independent and significant association with HBV infection. Top 3 reasons for doing HBsAg test were free screening (40.3%), blood donation (15.0%) and administrative requirements (14.9%). HBV testing uptake and early detection can be improved if more sensitization and free/opportunistic screenings are implemented. A significant drop in the cost of HBV test could encourage more people to get tested.

Abstract
A suboptimal blood vitamin C (ascorbate) level increases the risk of several chronic diseases. However, the detection of hypovitaminosis C is not a simple task, as ascorbate is unstable in blood samples. In this study, we examined the serum proteome of mice lacking the gulonolactone oxidase (Gulo) required for the ascorbate biosynthesis. Gulo-/- mice were supplemented with different concentrations of ascorbate in drinking water, and serum was collected to identify proteins correlating with serum ascorbate levels using an unbiased label-free liquid chromatography-tandem mass spectrometry global quantitative proteomic approach. Parallel reaction monitoring was performed to validate the correlations. We uncovered that the serum proteome profiles differ significantly between male and female mice. Also, unlike Gulo-/- males, a four-week ascorbate treatment did not entirely re-establish the serum proteome profile of ascorbate-deficient Gulo-/- females to the optimal profile exhibited by Gulo-/- females that never experienced an ascorbate deficiency. Finally, the serum proteins involved in retinoid metabolism, cholesterol, and lipid transport were similarly affected by ascorbate levels in males and females. In contrast, the proteins regulating serum peptidases and the protein of the acute phase response were different between males and females. These proteins are potential biomarkers correlating with blood ascorbate levels and require further study in standard clinical settings. The complete proteomics data set generated in this study has been deposited to the public repository ProteomeXchange with the data set identifier: PXD027019.

Abstract
Hepatitis B virus (HBV) infection is an infectious disease that is specific to the liver, causing both acute and chronic hepatitis. This study determined the trend of HBV infection among blood donors in the Kpandai District Hospital from January 2014 to December 2018. Retrospective analysis of donor profiles for a period of 5 years was used to assess the distribution of seropositive cases in relation to age, sex, and trend. The data was collected using pre-designed questionnaire and managed using Microsoft Excel spread sheet 2013. The overall sero-prevalence of HBV was 8.2% (230/2802). The year to year analysis depicted significant trends in reduction of HBV infection among the study population at a rate of 13 percentage points above the mean from 2014 to 2015, and 4.3 percentage points below the mean from 2016 to 2018 across the period. The prevalence in males was 8.4% (225/2687) and that of the females was 4.4% (5/115) and the highest rate of infection was among those below 30 years 9.8% (163/1666). Although the general prevalence of HBV infection was high (8.2%), there was a significant trend reduction in rate of infection across the study period. This suggests that the public health interventional strategies put in place to manage the HBV infection in Kpandai District seem to be working.

Pre-transplant donor HBV DNA+ and male recipient are independent risk factors for treatment failure in HBsAg+ donors to HBsAg- kidney transplant recipients. BMC Infect Dis 2021; 21:41. [PMID: 33422017 PMCID: PMC7796645 DOI: 10.1186/s12879-020-05704-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Accepted: 12/09/2020] [Indexed: 02/08/2023] Open
Abstract
Background In order to reduce the burden on organ shortage around the world, using potential infectious donor might be an option. However, scarce evidences have been published on kidney transplantation (KTx) from hepatitis B surface antigen (HBsAg) + donors to HBsAg- recipients [D (HBsAg+)/R(HBsAg-)] without hepatitis B virus (HBV) immunity. Here, we reported the results of D(HBsAg+/HBV DNA- or +)/R(HBsAg-) living KTx recipients with or without HBV immunity. Methods We retrospectively identified 83 D(HBsAg+)/R(HBsAg-) living KTx recipients, and 83 hepatitis B core antibody (HBcAb) + living donors to HBcAb- recipients [D(HBcAb+)/R(HBcAb-)] were used as control group by reviewing medical archives and propensity score matching. Treatment failure (defined as any HBV serology conversion, liver injury, graft loss, or recipient death) is the primary endpoint. Results Twenty-four donors (28.9%) were HBV DNA+, and 20 recipients had no HBV immunity in the D(HBsAg+)/R(HBsAg-) group pre-transplantation. HBV prophylaxis was applied in all D(HBsAg+)/R(HBsAg-) recipients, while none was applied in the D(HBcAb+)/R(HBcAb-) group. We observed a significant higher treatment failure in D(HBsAg+)/R(HBsAg-) than D(HBcAb+)/R(HBcAb-) group (21.7% vs. 10.8%, P < 0.001). Interestingly, no significant difference was found between groups on HBV seroconversion, liver and graft function, rejection, infection, graft loss, or death. However, 2/20 recipients without HBV immunity in the D(HBsAg+)/R(HBsAg-) group developed HBV DNA+ or HBsAg+, while none observed in the D(HBcAb+)/R(HBcAb-) group. HBV DNA+ donor and male recipient were significant risk factors for treatment failure. Conclusion D(HBsAg+)/R(HBsAg-) should be considered for living kidney transplantation, but with extra caution on donors with HBV DNA+ and male candidates.

Abstract
INTRODUCTION hepatitis B is a global public health problem. The purpose of this study was to determine the prevalence of hepatitis B virus (HBV) and its associated factors based on data from a mass screening in several localities across Benin. METHOD we conducted a cross-sectional descriptive and analytical study with prospective data collection. Data collection was carried out during voluntary free hepatitis B screening organized by the Rotary Club in 23 localities across Benin from the 20th to 28th July 2019. Rapid test for diagnostic orientation was used for the detection of HBs antigen. RESULTS a total of 9035 volunteers were included in the study. They were mostly of Benin origin (99%), with a mean age of 27 years; 51.1% of them were singles, mainly schoolchildren, pupils or students (37.9%). HBV seroprevalence was 6% (545/9035) [95%CI=5.5%-6.5%]. In univariate analysis, factors associated with HBs Ag colonization were: age, sex, marital status, education level, occupation and a history of diabetes, scarification and hepatitis C, while in multivariate analysis they were: sex, age and education level. CONCLUSION HBV seroprevalence is 6% in the study population. HBV infection mainly affects male subjects over 17 years of age with secondary-level education.

Abstract
BACKGROUND The management of patients with chronic hepatitis B infection is quite complex because it requires an in-depth knowledge of the natural history of the disease. This study was aimed at characterizing HBV infected patients in order to determine the phase of the infection and identify the proportion eligible for treatment using 3 different guidelines. METHODS HBV chronically infected patients (negative for HIV and HCV) were enrolled and the following tests were done for them: ALT, AST, HBV viral load, HBV serologic panel and Full blood count. APRI score was calculated for all patients. These patients were classified into immunotolerant, immune clearance, immune control and immune escape phases of the infection. The WHO and the 2018 AASLD criteria was also used to identify those who need treatment. Patients were clinically examined for signs and symptoms. Questionnaire was administered to all participants to ascertain their treatment status. Statistical analysis was done using SPSS version 21. RESULTS A total of 283 participants (101 females and 182 males) with a mean age of 31.3±8.5 were enrolled. Fifty-two (18.4%) were eligible for treatment (Immune clearance and immune escape phases) and they recorded a significantly higher mean APRI score (0.71±0.51) as compared to those in the immune control and immune tolerant phase (0.43±0.20). Based on WHO and AASLD criteria, 12(4.2%) and 15 (5.3%) were eligible for treatment respectively and these were all subsets of the 52 cases mentioned above. Six (2.1%) and 29 (10.2%) of those identified under the immune control phase were on tenofovir and traditional medication respectively. CONCLUSION Considering treatment for patients in the immune clearance and immune escape phases of the infection can be a reliable strategy to implement in our setting as this may probably tie with considerations from other treatment guidelines. Fifty-two (18.4%) patients were eligible for treatment and none of them were among the 2.1% of patients put on Tenofovir based treatment. This calls for the need for more trained health experts to periodically assess patients, implement an adequate treatment guideline and place the right patients on treatment in Cameroon.

Abstract
Chronic Hepatitis B (CHB) infection and subsequent liver complications are rising in prevalence in Australia due to increased migration from endemic regions. Nearly 50% of all those living with CHB in Australia are undiagnosed, leading to missed opportunities for liver cancer and cirrhosis prevention. Health literacy around CHB among refugee communities such as Afghan, Rohingyan, and Sudanese populations (all with a high prevalence of CHB) is low, partly due to a paucity of targeted health promotion programmes; despite the release of the Victorian Hepatitis B Strategy (2016-2020). We developed a peer-education intervention in these three communities to deliver CHB focused radio programmes and community forums in their own language, following a needs assessment consisting of semistructured interviews and surveys. Effectiveness of this intervention was measured through paired comparison of disease-knowledge assessment pre and post forum. Community forums were held between 2015 and 2016, with 25 attendees at the Rohingyan forum (68% male), 10 attendees at the Afghan forum (90% male) and 0 attendees at the Sudanese forum. Participants demonstrated a significant improvement in CHB knowledge between pre- and post-forum surveys (p-value < 0.05). A peer-educator approach was a cost-effective health promotion strategy in building CHB knowledge and dispelling misconceptions within the Afghan and Rohingya communities. There were significant barriers in the engagement of the South Sudanese community, which will inform future strategies for health promotion.

Abstract
Introduction Hepatitis B virus (HBV) infection is a major health challenge in sub-Saharan African countries. Chronic HBV infection is a risk factor for severe disease progression. Perinatal and sexual transmissions of Hepatitis B virus are the main routes of infection in HBV endemic countries like Nigeria. However, there is paucity of data as regards the major contributory route of transmission to chronic HBV infection in this region. Also, in Nigeria, not everyone at high risk of the infection has been identified. Therefore our study investigated the prevalence of HBV infection among sexually active individuals in Nigeria. Methods Blood samples collected from 463 participants (360 sexually active individuals and 103 teenagers) recruited from health institutions across the country were tested for the presence of HBsAg, and HBV nucleic acid related antigen (HBVNRAg) by ELISA. Positive samples were further tested for the presence of HBeAg and antiHBe by ELISA. Data were analyzed using Chi-square and binary logistic regression at p = 0.05. Results HBsAg and HBVNRAg were detected in 10.4% and 7.6% of the participants respectively. STI clinic attendees had the highest prevalence for HBsAg (17%; p = 0.002). Teenagers had the lowest HBsAg (1.9; p = 0.002) and HBVNRAg (2.9%; p = 0.0001) prevalence rates. Male gender (p = 0.01) and reproductive age group (p=0.009) were the major predictors of chronic HBV infection. Conclusion Sexual transmission was identified as the major contributor to chronic HBV infection. Sexually active individuals especially those with STIs are high risk groups for chronic HBV infection. Interventions targeted at this group is therefore recommended.

Abstract
Dysregulation of the neddylation pathway is related to various cancers. However, the specific role of the neddylation pathway in human hepatocellular carcinoma (HCC) remains largely unclear. In this study, the neddylation pathway in HCC and adjacent noncancerous liver (ANL) tissues was evaluated by immunohistochemistry (IHC), Western blotting, and qRT‐PCR (quantitative real‐time polymerase chain reaction). The results showed that the entire neddylation pathway, including NEDD8 (the IHC staining of NEDD8 represents the global‐protein neddylation), E1 NEDD8‐activating enzymes (NAE1 and UBA3), E2 NEDD8‐conjugating enzymes (UBE2F and UBE2M), E3 NEDD8‐ligases (MDM2, RBX1 and RNF7), and deneddylation enzymes (COPS5, UCHL1 and USP21), was overactivated in HCC. Furthermore, the upregulation of NEDD8 in HCC was correlated with aggressive characteristics and was an independent risk factor for overall survival (OS) and recurrence‐free survival (RFS) in patients with HCC after hepatectomy. The upregulation of NAE1, UBE2M, and UCHL1 in HCC was associated with aggressive characteristics and poor OS and RFS in patients with HCC after hepatectomy. In conclusion, our research reveals that the entire neddylation pathway is overactivated in HCC and associated with clinical characteristics and prognosis of patients with HCC.

Abstract
INTRODUCTION Triple infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis D virus (HDV) is rare. There is limited data on the seroprevalence of HIV/HBV/HDV tri-infection especially in Nigeria. The aim of this study was to determine the seroprevalences of HBsAg and HDV among HIV-infected individuals attending anti-retroviral (ARV) clinics in Abuja, Nigeria. METHODS In this cohort study, blood samples were collected from 1102 (male = 450; female = 652), with age range <20 to ≥51 years (mean age = 34.0; SD = 11.5), consenting HIV-infected population attending ARV clinics at selected health facilities in Abuja, Nigeria, between April and October 2016. A well-structured questionnaire was used to capture demographic information from the respondents. Enzyme-linked immunosorbent assay (ELISA) was used to determine the seroprevalence of hepatitis B surface antigen and anti-HDV. The result was interpreted according to manufacturer's instruction. Statistical data were analyzed using SPSS software version 21, and chi-square (χ2) test was used to determine association with P < 0.05 considered significant. RESULTS Overall seroprevalences of 10.3%, 7.1%, and 0.7% for HBV, HBV/HDV, and HIV/HBV/HDV, respectively, were found among the study population. The infection rate (13.3%) peaked at age range of 31-40 years for HBV (P = 0.002), 50% at <20 years for HBV/HDV (P = 0.049), and 1.5% at 31-40 years for HIV/HBV/HDV (P = 0.202). By gender, the rate was higher in males (10.9%, 10.2%, 1.1%) than females (9.8%, 4.9%, 0.5%) for HBV, HBV/HDV, and HIV/HBV/HDV infections, respectively. However, there was no significant association between infection rate and gender. CONCLUSION This study has established that HBV and HDV prevalence is still high in the population studied and that the rate of triple infection is low. We advocate for more robust control measures for HBV which should be extended to HDV in HIV population through screening and vaccination.

Abstract
The proteome of liver biopsies from human obese (O) subjects has been compared to those of nonobese (NO) subjects using two-dimensional gel electrophoresis (2-DE). Differentially represented proteins were identified by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS)-based peptide mass fingerprinting (PMF) and nanoflow-liquid chromatography coupled to electrospray-tandem mass spectrometry (nLC-ESI-MS/MS). Overall, 61 gene products common to all of the liver biopsies were identified within 65 spots, among which 25 ones were differently represented between O and NO subjects. In particular, over-representation of short-chain acyl-CoA dehydrogenase, Δ(3,5)-Δ(2,4)dienoyl-CoA isomerase, acetyl-CoA acetyltransferase, glyoxylate reductase/hydroxypyruvate reductase, fructose-biphosphate aldolase B, peroxiredoxin I, protein DJ-1, catalase, α- and β-hemoglobin subunits, 3-mercaptopyruvate S-transferase, calreticulin, aminoacylase 1, phenazine biosynthesis-like domain-containing protein and a form of fatty acid-binding protein, together with downrepresentation of glutamate dehydrogenase, glutathione S-transferase A1, S-adenosylmethionine synthase 1A and a form of apolipoprotein A-I, was associated with the obesity condition. Some of these metabolic enzymes and antioxidant proteins have already been identified as putative diagnostic markers of liver dysfunction in animal models of steatosis or obesity, suggesting additional investigations on their role in these syndromes. Their differential representation in human liver was suggestive of their consideration as obesity human biomarkers and for the development of novel antiobesity drugs.

Abstract
OBJECTIVE The expression of B-cell lymphoma 2 (Bcl-2) seems to be influenced by the endocrine environment. Numerous reports demonstrate the diverse expression of Bcl-2 family members under sex steroid regulation. With the exception of estrogen-related tumors, androgen-related tumors have shown their characteristics in Bcl-2 expression. In this study, the status of Bcl-2 expression in male hepatocellular carcinoma (HCC) patients was examined to verify the high incidence of HCC in males. METHODS Tumor tissue microarray was used to examine Bcl-2 expression levels in 374 HCC cases including 306 males and 68 females. Kaplan-Meier method, log-rank test, and Cox proportional hazards model were applied to investigate the predictive value of Bcl-2 in HCC patients. RESULTS Immunohistochemistry analysis showed that male patients with higher Bcl-2 levels had significantly longer median survival time and recurrence time than those with lower levels. However, no significant differences in outcomes were found between different Bcl-2 levels in female patients. When the male patients were stratified into several age points, the level of Bcl-2 expression showed poorer predictive efficiency in the 45-49 and 55-60 age groups in andropause-age patients compared with other age groups. Bcl-2 was an independent prognostic factor for both overall survival (P < 0.0001) and recurrence time (P = 0.0001) in male patients. After excluding male patients in the 45-60 age group, the predictive efficiency was enhanced (n = 147, OS, P = 0.0002, TTR, P < 0.0001). CONCLUSIONS Bcl-2 expression is an independent predictor of survival and recurrence in male HCC. Bcl-2 levels may also be regulated by androgens or androgen receptors in male HCC patients. Bcl-2 levels change and exhibit poor predictive efficiency when androgen levels vary dramatically (andropause age).

Abstract
BACKGROUND & AIMS The outcome of HBeAg-negative chronic hepatitis B virus (HBV) patients who may remain in the inactive carrier state (IC) or progress to HBeAg-negative chronic hepatitis B may be affected by the host genetic profile. Genetic polymorphisms within not only the promoter but also the coding sequence of the interferon receptor 1 (INFAR1) gene have been associated with susceptibility to chronic HBV infection, but their role on the outcomes of HBeAg-negative patients has not been evaluated. We examined the association of INFAR1 promoter polymorphisms with the phase of chronic HBV infection in a demographically characterized Caucasian cohort of 183 consecutive HBeAg-negative chronic HBV patients. METHODS Using a combination of conventional and allele-specific polymerase chain reactions, bidirectional sequencing and DNA-fragment analysis, we performed typing of three Single Nucleotide Polymorphisms (SNPs -568G/C, -408C/T, -3C/T) and one Variable Number Tandem Repeat [VNTR -77(GT)n] within the INFR1 promoter sequence. RESULTS The genetic polymorphisms examined were found to be associated with the phase of HBeAg-negative chronic HBV patients. Using a multiple logistic regression model adjusting for age, gender and origin of the individuals, we found that patients with linked genotypes -408CT_-3CT were more likely to be ICs (OR = 2.42 vs. CC, P = 0.036). Also, given the partial linkage between SNP -568G/C and VNTR -77(GT)n, we found that linked genotypes -77(GT)n ≤ 8/≤8_-568GC and -77(GT)n ≤ 8/≤8_-568CC were detected more frequently among ICs (OR = 11.69, P = 0.005 and OR = 7.56, P = 0.001 vs. -77(GT)n >8/>8_-568GG respectively). CONCLUSIONS These findings suggest that these genetic variations represent important factors associated with the clinical phase of HBeAg-negative chronic HBV infection.

Abstract
Apolipoprotein A-I (Apo A-I) is a major protein in lipid/lipoprotein metabolism and decreased serum levels have been observed in many species in response to inflammatory and infectious challenges. Little is known about the porcine homologue, therefore in this work we have characterized it through biochemical and proteomic techniques. In 2DE, porcine serum Apo A-I is found as three spots, the two more acidic ones corresponding to the mature protein, the more basic spot to the protein precursor. Despite high sequence coverage in LC-MS/MS, we did not find a sequence or PTM difference between the two mature protein species. Besides this biochemical characterization, we measured overall levels and relative species abundance of serum Apo A-I in four different viral and bacterial porcine infectious diseases. Lower overall amounts of Apo A-I were observed in Salmonella typhimurium and Escherichia coli infections. In the 2DE protein pattern, an increase of the protein precursor together with a lower level of mature protein species were detected in the porcine circovirus type 2-systemic disease and S. typhimurium infection. These results reveal that both the porcine serum Apo A-I concentration and the species pattern are influenced by the nature of the infectious disease.

Abstract
Background Hepatitis B virus (HBV) infection poses a serious threat to human health, with China being one of the highly affected countries. However, the pathogenesis of chronic hepatitis B (CHB) is still unclear. Apolipoprotein A1 (ApoA1) which represents the major protein component of high-density lipoprotein is normally secreted by hepatocytes. When hepatocytes are infected with HBV may lead to the disruption of ApoA1 secretion. In this study, we investigated the effect of HBV on ApoA1 expression and preliminarily explored its molecular mechanism of regulation for revealing the pathogenesis of CHB. Methods The expression of mRNA and protein of ApoA1 in Human HepG2 hepatoblastoma cells and subline HepG2.2.15 cells were performed by reverse transcription-polymerase chain reaction (RT-PCR) and Western-blot. The serum ApoA1, by the immune turbidimetric test, and high-density lipoprotein cholesterol (HDL-C) in CHB patients and healthy controls, based on the enzymatic method, were measured with autobiochemical analyzer. The statistical difference was analyzed by SPSS 13.0. HBV infectious clone, pHBV1.3, and ApoA1 gene promoter were co-transfected into HepG2, and the luciferase activity was determined. The changes of ApoA1 mRNA and protein expression were detected by RT-PCR and Western-blot method, after HepG2 cells were transfected with pHBV1.3. Results The expression of ApoA1 mRNA and protein in HepG2.2.15 were lower than those in HepG2, and when compared with healthy controls, serum levels of ApoA1 and HDL-C in CHB patients were lower (P < 0.05). pHBV1.3 in HepG2 cells restrained the activity of ApoA1 promoter, mRNA and protein expression. Conclusions HBV could inhibit the expression of ApoA1 in vitro and in vivo.

Abstract
Androgen/androgen receptor (AR) signaling plays important roles in normal liver function and in progression of liver diseases. In studies of noncancerous liver diseases, AR knockout mouse models of liver disease have revealed that androgen/AR signaling suppresses the development of steatosis, virus-related hepatitis, and cirrhosis. In addition, studies have shown that targeting AR in bone marrow-derived mesenchymal stem cells (BM-MSCs) improves their self-renewal and migration potentials, thereby increasing the efficacy of BM-MSC transplantation as a way to control the progression of cirrhosis. Androgen/AR signaling is known to be involved in the initiation of carcinogen- or hepatitis B virus-related hepatocellular carcinoma (HCC). However, studies have demonstrated that AR, rather than androgen, plays the dominant role in cancer initiation. Therefore, targeting AR might be an appropriate therapy for patients with early-stage HCC. In contrast, androgen/AR signaling has been shown to suppress metastasis of HCC in patients with late-stage disease. In addition, there is evidence that therapy comprising Sorafenib and agents that enhance the functional expression of AR may suppress the progression of late-stage HCC.

Abstract
AIM: To explore the effect of Bailing capsules in the treatment of proteinuria in patients with chronic nephritis (liver and kidney Yin deficiency).
METHODS: Eighty-four chronic nephritis patients with proteinuria were randomly divided into either an experimental group or a control group. The control group was treated by tripterysium glycosides, perindopril tablets and Warfarin sodium tablets, while the experimental group was additionally given Bailing capsules on the basis of the treatments for the control group. The clinical effects, symptom score, blood pressure, ALB, and the improvement of 24 h urinary protein quantity (UPQ) were compared between the two groups.
RESULTS: The response rate in the experimental group was significantly better than that in the control group (61.90% vs 40.48%, P < 0.05). The scores of various symptoms in the experimental group after treatment were significantly lower than those before treatment (1.47 ± 0.42 vs 3.60 ± 0.96, 1.93 ± 0.48 vs 3.60 ± 1.02, 1.93 ± 0.46 vs 3.13 ± 0.96, 1.80 ± 0.40 vs 3.20 ± 0.88, 1.27 ± 0.38 vs 2.27 ± 0.75, P < 0.05). There were no significant differences in the dysphoria with feverish sensation in chest, tidal fever and night sweating, the score of dry eyes or the score of blurring of visiona between before and after treatment in the control group (2.87 ± 0.59 vs 3.33 ± 1.01, 2.80 ± 0.52 vs 3.20 ± 0.91, P > 0.05). Edema, dysphoria with feverish sensation in chest, tidal fever and night sweating, the score of dry eyes and the score of blurring of vision in the experimental group were significantly lower than those in the control group (1.47 ± 0.42 vs 2.27 ± 0.58, 1.93 ± 0.48 vs 2.87 ± 0.59, 1.80 ± 0.40 vs 2.80 ± 0.52, P < 0.05). The levels of blood pressure and 24hUPQ were significantly lower (77.13 ± 6.12 vs 86.79 ± 16.88, 0.59 ± 0.31 vs 2.06 ± 0.60, 81.16 ± 7.08 vs 85.68 ± 16.95, 0.98 ± 0.68 vs 2.07 ± 0.64, P < 0.05) and the levels of ALB (36.83 ± 10.62 vs 30.18 ± 6.77, 33.27 ± 7.11 vs 30.20 ± 6.59, P < 0.05) were significantly higher after treatment in the two groups compared with pretreatment values. The levels of blood pressure and 24hUPQ in the experimental group were significantly lower than those in the control group (77.13 ± 6.12 vs 81.16 ± 7.08, 0.59 ± 0.31 vs 0.98 ± 0.68, P < 0.05), and the levels of ALB in the experimental group were significantly higher than those in the control group (36.83 ± 10.62 vs 33.27 ± 7.11, P < 0.05).
CONCLUSION: Bailing capsules can improve clinical symptoms and urine protein levels in chronic nephritis patients with proteinuria on the basis of conventional treatments.

Abstract
UNLABELLED HBx is well-known to be a multifunctional protein encoded by HBV and its biological functions are mainly dependent on pleiotropic protein-protein interactions (PPIs); however, the global mapping of HBx-interactome has not been established so far. Thus, in this study, we have identified 127 HBx-interacting proteins by a profound GST pull-down assay coupled with mass spectrometry, and constructed an HBx-interactome network and core apoA-I pathways with a series of bioinformatics approaches. One of the identified HBx-binding partners is apolipoprotein A-I (apoA-I), which has a specific role in lipid and cholesterol metabolism. The HBx-apoA-I protein interaction was confirmed by both GST pull-down and co-immunoprecipitation. The ectopic overexpression of apoA-I can lead to a significant inhibition on HBV secretion concomitant with the reduction of cellular cholesterol level. In addition, HBV can modulate the function of apoA-I through HBx which might interact with the 44-189 residues of apoA-I and result in dysfunction of apoA-I such as decreased self-association ability, increased carbonyl level and impaired lipid-binding ability. Our results demonstrate an integrated physical association of HBx and host proteins, especially a novel interactor apoA-I that may influence the HBV secretion, which would shed new light on exploring the complicated mechanisms of HBV manipulation on host cellular functions. BIOLOGICAL SIGNIFICANCE HBx is well-known to be a multifunctional protein encoded by HBV and its biological functions are mainly dependent on pleiotropic protein-protein interactions. Although a series of HBx-interacting proteins have been identified, a global characterization of HBx interactome has not been reported. In this study, we have identified a total of 127 HBx-interacting proteins by a profound GST pull-down assay coupled with mass spectrometry, and constructed an HBx-interactome network with a series of bioinformatics approaches. Our results demonstrate an integrated physical association of HBx and host proteins which may help us explore the complicated mechanisms of HBV manipulation on host cellular functions. In addition, we validated one of the identified HBx-binding partners, apolipoprotein A-I (apoA-I), which played a significant inhibitory effect on HBV secretion, indicating a crucial role of the HBx-apoA-I axis in HBV life cycle.

Altered expression of apoA-I, apoA-IV and PON-1 activity in CBS deficient homocystinuria in the presence and absence of treatment: possible implications for cardiovascular outcomes. Mol Genet Metab 2012; 107:55-65.

Abstract
Classical homocystinuria (HCU) is caused by mutations in cystathionine beta-synthase (CBS) which, if untreated, typically results in cognitive impairment, thromboembolic complications and connective tissue disturbances. Paraoxonase-1 (PON1) and apolipoprotein apoA-I are both synthesized in the liver and contribute to much of the cardioprotective effects of high density lipoprotein. Additionally, apoA-I exerts significant neuro-protective effects that act to preserve cognition. Previous work in a Cbs null mouse model that incurs significant liver injury, reported that HCU dramatically decreases PON1 expression. Conflicting reports exist in the literature concerning the relative influence of homocysteine and cysteine upon apoA-I expression. We investigated expression of PON1 and apoA-I in the presence and absence of homocysteine lowering therapy, in both the HO mouse model of HCU and human subjects with this disorder. We observed no significant change in plasma PON1 paraoxonase activity in either mice or humans with HCU indicating that this enzyme is unlikely to contribute to the cardiovascular sequelae of HCU. Plasma levels of apoA-I were unchanged in mice with mildly elevated homocysteine due to CBS deficiency but were significantly diminished in both mice and humans with HCU. Subsequent experiments revealed that HCU acts to dramatically decrease apoA-I levels in the brain. Cysteine supplementation in HO mice had no discernible effect on plasma levels of apoA-I while treatment to lower homocysteine normalized plasma levels of this lipoprotein in both HO mice and humans with HCU. Our results indicate that plasma apoA-I levels in HCU are inversely related to homocysteine and are consistent with a plausible role for decreased expression of apoA-I as a contributory factor for both cardiovascular disease and cognitive impairment in HCU.

Abstract
The discovery phase of biomarkers of diagnostic or therapeutic interest started a decade ago with the very rapid development of proteomic investigations. In spite of the development of innovative technologies and multiple approaches, the "harvest" is still modest. Various reasons justified the encountered difficulties and most of them have been circumvented by specific sample treatments or dedicated analytical approaches. Nevertheless, the situation of very modest biomarker discovery level did not change much. This review intends to specifically analyze the main approaches used for biomarker discovery phase and evaluate related advantages and disadvantages. Thus, preliminary sample treatments such as fractionation, depletion and reduction of dynamic concentration range will critically be discussed and then the main differential expression investigation methods analyzed. Combinations of technologies are also discussed along with possible proposals to federate associations of complementary technologies for better chances of success.

Modulation of the unfolded protein response is the core of microRNA-122-involved sensitivity to chemotherapy in hepatocellular carcinoma. Neoplasia 2011; 13:590-600. [PMID: 21750653 DOI: 10.1593/neo.11422] [Citation(s) in RCA: 72] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2011] [Revised: 04/28/2011] [Accepted: 04/29/2011] [Indexed: 12/22/2022] Open
Abstract
The loss of microRNA-122 (miR-122) expression correlates to many characteristic properties of hepatocellular carcinoma (HCC) cells, including clonogenic survival, anchorage-independent growth, migration, invasion, epithelial-mesenchymal transition, and tumorigenesis. However, all of these findings do not sufficiently explain the oncogenic potential of miR-122. In the current study, we used two-dimensional differential in-gel electrophoresis to measure changes in the expression of thousands of proteins in response to the inhibition of miR-122 in human hepatoma cells. Several proteins that were upregulated on miR-122 inhibition were involved in the unfolded protein response (UPR) pathway. The overexpression of miR-122 resulted in the repression of UPR pathway activation. Therefore, miR-122 may act as an inhibitor of the chaperone gene expression and negatively regulate the UPR pathway in HCC. We further showed that the miR-122 inhibitor enhanced the stability of the 26S proteasome non-ATPase regulatory subunit 10 (PSMD10) through the up-regulation of its target gene cyclin-dependent kinase 4 (CDK4). This process may activate the UPR pathway to prevent chemotherapy-mediated tumor cell apoptosis. The current study suggests that miR-122 negatively regulates the UPR through the CDK4-PSMD10 pathway. The down-regulation of miR-122 activated the CDK4-PSMD10-UPR pathway to decrease tumor cell anticancer drug-mediated apoptosis. We identified a new HCC therapeutic target and proclaimed the potential risk of the therapeutic use of miR-122 silencing.

Abstract
BACKGROUND Taiwan launched a nationwide infant vaccination program for hepatitis B (HB) in 1984. OBJECTIVES This study evaluated the seroprevalence of hepatitis B virus (HBV) and the incidence of high alanine aminotransferase (ALT) level among young adults prior to, during, and since the introduction of the nationwide HBV vaccination program. STUDY DESIGN Researchers recruited 101,584 freshmen (male:female=1.114:1; mean age, 18.5±0.5 years) from 21 universities between 1995 and 2009 (birth cohorts 1977-1991) in Taiwan, testing for serum hepatitis B surface antigens (HBsAg), hepatitis e antigens (HBeAg), antibodies against HBsAg (anti-HBs), and liver function tests, including ALT and aspartate aminotransferase (AST). RESULTS The results showed that the prevalence of HBsAg decreased significantly from 14.3% in 1995 to 1.1% in 2009 and the seroprevalence of HBeAg decreased significantly from 5.9% in 1995 to 0.3% in 2009. Seroconversion to anti-HBs maintained a steady rate above 50% between 1995 and 2007, but declined considerably to 36.6% and 36.4% in 2008 and 2009, respectively. Subject with HBeAg seropositivity was in 43.94% of HBV carriers. Double seronegativity for HBsAg and anti-HBs was observed in 2007 (47.8%), 2008 (62.3%), and 2009 (62.5%). High ALT level was observed in 5.74% of the subjects, particular among HBV-carriers (16.5% of HBV carrier vs. 5.0% of non-HBV carrier; ORs, 3.733; 95% CIs, 3.463-4.023, p<0.0001). Subjects with high ALT level were significantly positively associated with HBeAg (10.5% of HBeAg seropositive vs. 1.9% of HBeAg seronegative; ORs, 6.195; 95%CI, 5.629-6.818; p<0.0001). Male subjects were more easily infected by HBV than female subjects were (HBsAg, ORs, 1.355, 95% CI, 1.283-1.431; HBeAg, ORs, 1.324, 95% CI, 1.218-1.439, p<0.0001), and significantly more male subjects had high ALT levels than female subjects did (ORs, 4.087; 95% CI, 3.819-4.375, p<0.0001). CONCLUSIONS The mass vaccination program successfully reduced the HBV carrier rate and prevalence of chronic hepatitis B in Taiwan. However, the low percentage of anti-HBV in 2008 and 2009 remains unresolved.

Abstract
Apolipoprotein A-I (ApoA-I) is the major protein component of high density lipoprotein (HDL) particles in serum, and participates in the reverse transport of cholesterol from tissues to the liver for excretion. The natural HDL tropism to the liver and cancer cells has been used extensively to target encapsulated drugs. The alteration of the plasmatic isoforms of ApoA-I is a hallmark of chronic hepatitis and hepatocarcinoma in mice and humans. Woodchucks infected with the woodchuck hepatitis virus (WHV) represent the best animal model for the study of chronic viral hepatitis B and viral induced hepatocarcinoma (HCC). WHV-infected woodchuck represents a clinically relevant animal model under which new treatment strategies can be evaluated and optimized. Therapeutic efficacy in this model is likely to be translated into a successful therapy for patients infected with HBV. The present study describes, for the first time, the cloning and characterization of woodchuck ApoA-I. The open reading frame (ORF) of the woodchuck ApoA-I is 795 bp long, coding for 264 amino acids. Unexpectedly, phylogenetic analysis revealed that the closest sequences are those of human and macaque. Woodchuck HDLs were isolated successfully from sera by density gradient ultracentrifugation. A commercial antibody that recognized the woodchuck ApoA-I was also identified. Finally, taking advantage of the techniques and tools developed in this study, two potential applications of woodchuck HDLs are illustrated: drug delivery to a woodchuck hepatocarcinoma cell line and the use of isoelectrofocusing to identify ApoA-I isoforms.

Abstract
AIM: To explore the molecular mechanism underlying the development of Yin deficiency of the liver and kidneys in patients with chronic hepatitis B by comparing plasma protein expression between chronic hepatitis B patients with Yin deficiency of the liver and kidneys and normal controls.
METHODS: Plasma proteins from all experimental subjects were separated by two-dimensional gel electrophoresis (2-DE). The proteomic expression profiles were analyzed by comparative proteomic technique to discover differentially expressed protein spots, which were then identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
RESULTS: Six protein spots which showed at least two-fold differential expression between patients and normal controls were detected, of them Apo AI, Apo AII, haptoglobin, and retinol-binding protein were identified by MALDI-TOF-MS. All the four proteins showed lower expression in chronic hepatitis B patients with Yin deficiency of the liver and kidneys than in normal controls.
CONCLUSION: The proteins identified in this study may be related to the development of Yin deficiency of the liver and kidneys in patients with chronic hepatitis B and represent useful molecular targets for diagnosis and treatment of the syndrome.

Abstract
Long term hepatitis B virus (HBV) infection is a major risk factor in pathogenesis of chronic liver diseases, including hepatocellular carcinoma (HCC). The HBV encoded proteins, hepatitis B virus X protein and preS, appear to contribute importantly to the pathogenesis of HCC. Both are associated with oxidative stress, which can damage cellular molecules like lipids, proteins, and DNA during chronic infection. Chronic alcohol use is another important factor that contributes to oxidative stress in the liver. Previous studies reported that treatment with antioxidants, such as curcumin, silymarin, green tea, and vitamins C and E, can protect DNA from damage and regulate liver pathogenesis-related cascades by reducing reactive oxygen species. This review summarizes some of the relationships between oxidative stress and liver pathogenesis, focusing upon HBV and alcohol, and suggests antioxidant therapeutic approaches.

Abstract
OBJECTIVE The accumulation of old and damaged proteins likely contributes to complications of diabetes, but currently no methodology is available to measure the relative age of a specific protein alongside assessment of posttranslational modifications (PTM). To accomplish our goal of studying the impact of insulin deficiency and hyperglycemia in type 1 diabetes upon accumulation of old damaged isoforms of plasma apolipoprotein A-1 (ApoA-1), we sought to develop a novel methodology, which is reported here and can also be applied to other specific proteins. RESEARCH DESIGN AND METHODS To label newly synthesized proteins, [ring-(13)C(6)]phenylalanine was intravenously infused for 8 h in type 1 diabetic participants (n = 7) during both insulin treatment and 8 h of insulin deprivation and in nondiabetic participants (n = 7). ApoA-1 isoforms were purified by two-dimensional gel electrophoresis (2DGE) and assessment of protein identity, PTM, and [ring-(13)C(6)]phenylalanine isotopic enrichment (IE) was performed by tandem mass spectrometry. RESULTS Five isoforms of plasma ApoA-1 were identified by 2DGE including ApoA-1 precursor (pro-ApoA-1) that contained the relatively highest IE, whereas the older forms contained higher degrees of damage (carbonylation, deamidation) and far less IE. In type 1 diabetes, the relative ratio of IE of [ring-(13)C(6)]phenylalanine in an older isoform versus pro-ApoA-1 was higher during insulin deprivation, indicating that de novo synthesized pro-ApoA-1 more rapidly accumulated damage, converting to mature ApoA-1. CONCLUSIONS We developed a mass spectrometry-based methodology to identify the relative age of protein isoforms. The results demonstrated accelerated oxidative damage to plasma ApoA-1, thus offering a potential mechanism underlying the impact of poor glycemic control in type 1 diabetic patients that affects a patient's risk for vascular disease.

Abstract
Hepatocellular carcinoma (HCC) represents the most common primary liver cancer and one of the most fatal human cancers. Besides alcoholic liver disease as well as genetic and environmental factors, hepatitis B and C viral infections also represent the most important risk factors for onset and development of the disease. In fact, HCC worldwide prevalence varies widely and mirrors the geographical distribution of chronic viral hepatitis. Interestingly, a gender difference was described for this disease: in almost all populations, a male/female ratio averaging between 2:1 and 4:1 was reported. Here, we analyze the implication of cytokines and sex hormones in this issue. Exploiting the emerging knowledge on the possible differential role of hepatitis viruses B and C, we discuss the role of reactive oxygen species and apoptosis dysregulation in the characterization of the molecular mechanisms of gender disparity in the development of HCC.
