Abstract Hepatitis B surface antigen (HBsAg) level plays an important role in conjunction with other markers such as hepatitis B envelope antigen (HBeAg) and hepatitis B virus (HBV) deoxyribonucleic acid levels to predict disease activity in chronic Hepatitis B (CHB). Quantification of HBsAg is useful in differentiating carriers from active hepatitis in HBeAg negative patients, and current guidelines recommend monitoring of pegylated interferon alpha treatment in CHB infection. However, there are only few studies about the role of quantitative HBsAg (qHBsAg) monitoring in HIV-HBV coinfected patients. Studies have ...

Abstract Virus-like particles (VLPs) are a type of subunit vaccine which resembles viruses but do not contain any genetic material so that they are not infectious. VLPs maintain the same antigenic conformation to the original virus, and they could be a better vaccine candidate than live-attenuated and inactivated vaccines. In addition, compared to other subunit vaccines such as soluble protein, VLPs can stimulate both innate and adaptive immune responses effectively and safely against several pathogens by the closer morphology to its native virus. They have already been licensed as vaccines against Hepatitis B vir...

Authors: Twumasi C, Asiedu L, Nortey ENN Abstract Several mathematical and standard epidemiological models have been proposed in studying infectious disease dynamics. These models help to understand the spread of disease infections. However, most of these models are not able to estimate other relevant disease metrics such as probability of first infection and recovery as well as the expected time to infection and recovery for both susceptible and infected individuals. That is, most of the standard epidemiological models used in estimating transition probabilities (TPs) are not able to generalize the transition esti...

In conclusion, circulating microRNAs, particularly the miR-125b, may serve as promising biomarkers for the early diagnosis of HBV-related HCC. However, larger and more rigorous studies are needed to confirm our conclusions.

Conclusions: Different outcomes in OS or PFS with respect to gender only exist in BCLC stage 0-B HBV-related HCC patients. Female patients have a better outcome than male patients in BCLC stage 0-B.

In this study, HepG2.2.15 cells showed decreased proliferation, G1 cell cycle arrest and increased apoptosis, when compared to HepG2 cells. HBV capture sequencing was conducted in both genome and transcriptome level, followed by RNA expression sequencing in HepG2.2.15. Here, CAMSAP2/CCDC12/DPP7/OR4F3 were found to be targets for HBV integration in both genome and transcriptome level, accompanied by alteration in their expression when compared to HepG2. Among these genes, DPP7 was the only one gene with HBV integration into its exon, meanwhile DPP7 expression level was also downregulated in HepG2.2.15 as compared to HepG2. ...

Background: Hepatitis B virus infection had been identified its relationship with liver diseases, including liver tumors. We aimed to explore diagnostic and prognostic values between the Human Leukocyte Antigen (HLA) complex and hepatocellular carcinoma (HCC).Methods: We used the GSE14520 dataset to explore diagnostic and prognostic significance between HLA complex and HCC. A nomogram was constructed to predict survival probability of HCC prognosis. Gene set enrichment analysis was explored using gene ontologies and metabolic pathways. Validation of prognostic values of the HLA complex was performed in the Kaplan-Meier Plo...

Conclusions: Key biomarkers and pathways identified in the present study may enhance the comprehend of the molecular mechanisms underlying hepatocarcinogenesis. Additionally, mRNA expression of PRC1 and TOP2A may serve as potential diagnostic and prognostic biomarkers for HBV-related HCC.

Gene methylation is an epigenetic alteration in hepatocellular carcinoma (HCC), and hepatitis B virus (HBV) plays a crucial role in carcinogenesis of HCC. However, the association between gene methylation and HBV infection in HCC remains unclear. In our study, we conducted a comprehensive meta-analysis to evaluate the association. A total of 1,148 studies were initially retrieved from some literature database. After a four-step filtration, we obtained 69 case-control studies in this meta-analysis. Our results showed six genes (p16, RASSF1A, GSTP1, APC, p15 and SFRP1) in HBV-positive carcinoma tissues, one gene (GSTP1) in H...
