REVIEW
Nirupama Trehanpati, Ashish Kumar Vyas
Hepatocellular carcinoma (HCC) is the leading cause of cancer death and hepatitis B virus (HBV) infection is one of the commonest causes in Asians countries. India has the second largest pool after China for hepatitis B infected subjects. HBV clearance is T cell dependent and one of the reason for T cells hypo responsiveness is due to mass production of Tregs through activation of Notch signaling, which suppressCD4/CD8 T cells. Regulatory T cells (Tregs) are important to maintain cellular homeostasis; however during viral infection increase of Tregs is inversely proportional to HBV DNA titers...

: The incidence and prevalence of inflammatory liver diseases has increased over the last years but therapeutic options are limited. Pregnancy induces a state of immune tolerance, which can result in spontaneous improvement of clinical symptoms of certain autoimmune diseases including autoimmune hepatitis (AIH). We investigated the immune suppressive mechanisms of the human pregnancy hormone chorionic gonadotropin (hCG) in the liver. HCG signaling activates SIRT1, which deacetylates FOXO3a, leading to repression of pro-apoptotic gene expression...

OBJECTIVE: To systematically explore the molecular mechanism for hepatocellular carcinoma (HCC) metastasis and identify regulatory genes with text mining methods. RESULTS: Genes with highest frequencies and significant pathways related to HCC metastasis were listed. A handful of proteins such as EGFR, MDM2, TP53 and APP, were identified as hub nodes in PPI (protein-protein interaction) network. Compared with unique genes for HBV-HCCs, genes particular to HCV-HCCs were less, but may participate in more extensive signaling processes...

In our study, the development of amino functionalized carbon coated magnetic nanoparticles (NH2-CC-MNPs) and their usage for electrochemical detection of hybridization of nucleic acids have been aimed. Firstly, NH2-CC-MNPs were prepared by coating of pristine Fe3O4 nanoparticles with two layers via caramelization and silanization processes respectively. After the morphological characterization with scanning electron microscopy (SEM) it was seen that NH2-CC-MNPs was spherical shaped and in 28nm sized. Investigation of chemical composition with the help of scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX) and fourier transform infrared spectroscopy (FTIR) was showed incorporation of carbon and APTES to the structure of NH2-CC-MNPs...

Hepatitis B virus (HBV) and hepatitis delta virus (HDV) co-infections progress rapidly and lead to cirrhosis. In Japan, the prevalence of HBV and HDV co-infected patients is low. Therefore, there are few reports of patients with HBV and HDV co-infection having undergone liver transplantation. Herein, we report a rare case of recurrence of HBV and HDV in a 41-year-old man who underwent living donor liver transplantation 4 years prior.

Hepatitis B virus X protein (HBx) and cancer stem-like cells (CSCs) have both been implicated in the occurrence and development of HBV-related hepatocellular carcinoma (HCC). However, whether HBx contributes to the stem-like properties of OV6(+) CSCs in HCC remains elusive. In this study, we showed that the concomitant expression of HBx and OV6 was closely associated with the clinical outcomes and prognosis of patients with HBV-related HCC. HBx was required for the stem-like properties of OV6(+) liver CSCs, including self-renewal, stem cell-associated gene expression, tumorigenicity and chemoresistance...

Chronic infections with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) add to age-dependent bone loss and may contribute to lower bone strength in the elderly. In this review, we report recent highlights on the epidemiology of bone fragility in chronic viral infections with HIV, HCV and HBV, its physiopathology and discuss the interference of antiviral therapies with bone metabolism. Chronic infections influence bone through the interactions between risk factors for bone fragility and falls (which are highly prevalent in infected patients), virus activity and antiviral drugs...

BACKGROUND & AIMS: Recently we have shown that cartilage oligomeric matrix protein (COMP), a fibrillar collagen assembly regulator, is strongly associated with cirrhosis and hepatocellular carcinoma progression. Therefore, we assessed whether serum COMP levels can be used as a non-invasive fibrosis marker in patients with chronic viral hepatitis (CVH) and compared this marker with standard methods for disease stage assessment [histology, transient elastography (TE), APRI, FIB-4]. METHODS: Sera from 116 CVH patients, 66 HBV [24 female; median age 53(22-76)] and 50 HCV [21 female; median age 48...
