SOCS and Herpesviruses, With Emphasis on Cytomegalovirus Retinitis
Christine I. Alston1,2 and Richard D. Dix1,2* 1Department of Biology, Viral Immunology Center, Georgia State University, Atlanta, GA, United States 2Department of Ophthalmology, Emory University School of Medicine, Atlanta, GA, United States Suppressor of cytokine signaling (SOCS) proteins provide selective negative feedback to prevent pathogeneses caused by overstimulation of the immune system. Of the eight known SOCS proteins, SOCS1 and SOCS3 are the best studied, and systemic deletion of either gene causes early lethality in mice. Many viruses, including herpesviruses such as herpes simplex virus and cytomega...

MicroRNA-325-3p inhibits cell proliferation and induces apoptosis in hepatitis B virus-related hepatocellular carcinoma by down-regulation of aquaporin 5.
Conclusions: Our findings clearly demonstrated that introduction of miR-325-3p inhibited proliferation and induced apoptosis of Huh7-1.3 and HepG2.2.15 cells by directly decreasing AQP5 expression, and that silencing AQP5 expression was essential for the pro-apoptotic effect of miR-325-3p overexpression on Huh7-1.3 and HepG2.2.15 cells. It is beneficial to gain insight into the mechanism of HBV infection and pathophysiology of HBV-related HCC. PMID: 30805015 [PubMed - in process]

5′-triphosphate siRNA targeting HBx elicits a potent anti-HBV immune response in pAAV-HBV transfected mice
Publication date: Available online 15 November 2018Source: Antiviral ResearchAuthor(s): Qiuju Han, Zhaohua Hou, Chunlai Yin, Cai Zhang, Jian ZhangAbstractRNA with 5′-triphosphate (3p-RNA) is recognized by RNA sensor RIG-I (retinoic acid–inducible gene I protein). Previously, we reported that small interfering RNA targeting HBx (3p-siHBx) could confer potent anti–hepatitis B virus (HBV) efficacy via HBx silencing and RIG-I activation. However, the characteristics of innate and adaptive immunity especially exhaustion profiles in the liver microenvironment in response to 3p-siHBx therapy have not been fully elucidated. ...

5'-triphosphate siRNA targeting HBx elicits a potent anti-HBV immune response in pAAV-HBV transfected mice.
Abstract RNA with 5'-triphosphate (3p-RNA) is recognized by RNA sensor RIG-I (retinoic acid-inducible gene I protein). Previously, we reported that small interfering RNA targeting HBx (3p-siHBx) could confer potent anti-hepatitis B virus (HBV) efficacy via HBx silencing and RIG-I activation. However, the characteristics of innate and adaptive immunity especially exhaustion profiles in the liver microenvironment in response to 3p-siHBx therapy have not been fully elucidated. Here, we observed that 3p-siHBx more significantly inhibited HBV replication in vivo. 3p-siHBx enhanced natural killer (NK) cell activation wi...

Overcoming immune tolerance in chronic hepatitis B by therapeutic vaccination
Publication date: June 2018Source: Current Opinion in Virology, Volume 30Author(s): Claudia Dembek, Ulrike Protzer, Michael RoggendorfThe currently used nucleoside analogs (i.e. entecavir and tenofovir) with high barrier-to-resistance efficiently suppress viral replication, limit inflammation and reduce the sequelae of chronic hepatitis B, but cannot cure the disease and thus have to be applied long-term. Therapeutic vaccination as an approach to cure chronic hepatitis B has shown promising pre-clinical results, nevertheless the proof of its efficacy in clinical trials is still missing. This may be partially due to subopti...

URG11 Regulates Prostate Cancer Cell Proliferation, Migration, and Invasion.
Abstract Upregulated gene 11 (URG11), a new gene upregulated by hepatitis B virus X protein, is involved in the development and progression of several tumors, including liver, stomach, lung, and colon cancers. However, the role of URG11 in prostate cancer remains yet to be elucidated. By determined expression in human prostate cancer tissues, URG11 was found significantly upregulated and positively correlated with the severity of prostate cancer, compared with that in benign prostatic hyperplasia tissues. Further, the mRNA and protein levels of URG11 were significantly upregulated in human prostate cancer cell lin...

HMGB1-induced autophagy facilitates hepatic stellate cells activation: a new pathway in liver fibrosis
High-mobility group box-1 (HMGB1) plays a context-dependent role in autophagy, which is required for hepatic stellate cells (HSCs) activation. However, the significance of HMGB1-induced HSCs autophagy in liver fibrosis has not been elucidated. Here, we first documented an enrichment of peripheral and intra-hepatic HMGB1 signal in hepatitis B virus (HBV)-related liver fibrosis progression, and presented the direct evidence of anatomic proximity of HMGB1 with a-SMA (a marker for HSCs activation) in cirrhotic liver specimens. Then, we demonstrated the autophagy-inducing effects by serum-sourced HMGB1 in both primary murine HS...

The expression and role of lncRNA AX800134 in hepatitis B virus-related hepatocellular carcinoma
In this study, we validated the upregulated expression of AX800134 in HBV-positive HCC compared with HBV-negative HCC. Furthermore, we found that HBV X protein (HBx) directly triggered AX800134 expression in human hepatoma HepG2 cells. Pro-inflammatory cytokine TNF α also induced AX800134 upregulation in HBx-expressing HepG2 cells, which could be reversed by reactive oxygen species (ROS) scavenger pyrrolidine dithiocarbamate (PDTC). Additionally, silencing AX800134 with siRNA interference remarkably inhibited the growth and invasion of HBx-expressing HepG2 ce lls. AX800134 antagonism also enhanced spontaneous apoptosis of...

Analysis of long non-coding RNA (lncRNA) expression in hepatitis B patients.
Authors: Yılmaz Susluer S, Kayabasi C, Ozmen Yelken B, Asik A, Celik D, Balci Okcanoglu T, Serin Senger S, Biray Avci C, Kose S, Gunduz C Abstract Long non-coding RNAs (lncRNAs) have been implicated in numerous biological processes, including epigenetic regulation, cell-cycle control, and transcriptional/translational regulation of gene expression. Differential expression of lncRNAs and disruption of the regulatory processes are recognized as critical steps in cancer development. The role of lncRNAs in hepatitis B virus (HBV) infection is not well understood. Here we analyzed the expression of 135 lncRNAs in plasm...

XBP1 activation enhances MANF expression via binding to endoplasmic reticulum stress response elements within MANF promoter region in hepatitis B.
Abstract As an endoplasmic reticulum (ER) stress-related protein, mesencephalic astrocyte-derived neurotrophic factor (MANF) is involved in inflammatory diseases, such as rheumatoid arthritis. However, the mechanisms of the transcriptional regulation of MANF is still undefined. Here, we showed that MANF expression was upregulated in hepatitis B tissues and hepatoma cells, and positively correlated with the spliced X-box binding protein-1 (XBP1s). Both overexpression of XBP1s and tunicamycin treatment were able to enhance MANF transcription. On the contrary, inhibition of XBP1 splicing by IRE1α endonuclease inhibi...

RNA-binding protein AUF1 suppresses miR-122 biogenesis by down-regulating Dicer1 in hepatocellular carcinoma.
In conclusion, AUF1 down-regulates the expression miR-122 by interacting with the 3'UTR and coding region of DICER1 mRNA and suppressing Dicer1 expression. The AUF1/Dicer1/miR-122 pathway might play a critical role in the development of HCC. PMID: 29599909 [PubMed]

Alpha ‐enolase regulates hepatitis B virus replication through suppression of the interferon signalling pathway
Summary Persistent chronic infection with hepatitis B virus (HBV) is a major risk factor for the development of HBV‐related diseases. The molecular mechanisms that underlie HBV infection and associated carcinogenesis are not fully understood. The aim of this study was to explore the role of ENO1 in HBV replication processes. Here, we examined ENO1 expression levels in HBV‐infected and non‐HBV‐infected liver tissues and cells by Western blot analysis, real‐time PCR and immunohistochemistry. In addition, HBsAg and HBeAg in the media of transfected HepG2.2.15 cells were detected using an electrochemical luminescence...
