Chronic infection by hepatitis C virus (HCV) is a major risk factor for the development of hepatocellular carcinoma (HCC). Despite the clear clinical importance of virus-associated HCC, the underlying molecular mechanisms remain largely unclarified. Oxidative stress, in particular, DNA lesions associated with oxidative damage, plays a major role in carcinogenesis, and is strongly linked to the development of many cancers, including HCC. However, in identifying hepatocytes with HCV viral RNA, estimates of the median proportion of HCV-infected hepatocytes have been found as high as 40% in patients with chronic HCV infection...

Hepatitis B virus X protein (HBx) plays an important role in the development of hepatocellular carcinoma (HCC). In addition, hepatoma upregulated protein (HURP) is a cellular oncogene that is upregulated in a majority of HCC cases. We highlight here recent findings demonstrating a link between HBx, HURP and anti-apoptosis effects observed in cisplatin-treated HCC cells. We observed that Hep3B cells overexpressing HBx display increased HURP mRNA and protein levels, and show resistance to cisplatin-induced apoptosis...

We report a lung transplant recipient who developed BK polyoma virus (BKPyV) DNAemia and BKPyV nephropathy. With careful management of his immunosuppression he achieved significant reduction in BKPyV DNAemia and stabilization of his kidney function. He later developed a high-grade bladder cancer and shortly thereafter he experienced a major upsurge in the level of BKPyV DNAemia that coincided with the discovery of hepatic metastasis. Retrospectively, the bladder cancer and the hepatic secondary tumor stained uniformly for SV40 large T antigen (SV40 LTAg), and the BKPyV DNA sequences identified in plasma corresponded to BKPyV DNA within hepatic tissue indicating that the spike in BKPyV load was likely derived from the circulating tumor cells or cell free tumor DNA following metastases of a BKV-associated cancer...

CONTEXT: Brassicaceae plants are associated with protection against cancers due to their glucosinolate contents. OBJECTIVES: We investigate fresh leaves, roots and ripe seeds of Lobularia libyca (Viv.) C.F.W. Meissn. (Brassicaceae) to identify their glucosinolate constituents, antimicrobial and cytotoxic activities Materials and methods: The glucosinolates were identified using GC-MS analysis of their hydrolysis products and LC-MS analysis in the case of seeds. Disc diffusion (1 mg/disc) and minimum inhibitory concentration (0-160 μg/mL) methods were used to evaluate the antimicrobial activity of seed hydrolysate...

Acute liver disease is characterized by inflammation, oxidative stress and necrosis, which can greatly influence the long term clinical outcome and lead to liver failure or cancer. Here, we initially demonstrated the beneficial role of caspase-9-dependent autophagy in acute liver injury. Treatment with caspase-9 inhibitor z-LEHD-FMK in HepG2 cells, AML12 cells and C57BL/b6N mice exacerbated CCl4-induced acute hepatocellular damage, and also down-regulated autophagy markers expression levels, indicating that caspase-9 inhibition may aggravate acute liver damage by suppressing cytoprotective autophagy...

Upregulated gene 11 (URG11), a new gene upregulated by hepatitis B virus X protein, was found to be involved in the development and progression of several tumors. However, the role of URG11 in human non-small cell lung cancer (NSCLC) has not yet been determined. Therefore, the aim of the present study was to explore the role of URG11 in human NSCLC. Our results found that URG11 was highly expressed in human NSCLC tissues compared with matched normal lung tissues, and higher levels were found in NSCLC cell lines in comparison to the normal lung cell line...

Immunotherapy with checkpoint inhibitors is an effective strategy for several cancers. In some patients long-term remissions are seen. However, enhancement of the immune response can be accompanied by immune-related adverse events (irAEs). These patients often present with nonspecific symptoms. The most common irAEs are dermatitis, colitis, pneumonitis, hepatitis and endocrinopathies. IrAEs can occur in every organ, even simultaneously. Furthermore, irAEs can occur weeks or months after discontinuation of checkpoint inhibitors...

The programmed cell death protein 1 (PD1) is one of the checkpoints that regulates the immune response. Ligation of PD1 with its ligands PDL1 and PDL2 results in transduction of negative signals to T-cells. PD1 expression is an important mechanism contributing to the exhausted effector T-cell phenotype. The expression of PD1 on effector T-cells and PDL1 on neoplastic cells enables tumor cells to evade anti-tumor immunity. Blockade of PD1 is an important immunotherapeutic strategy for cancers. Pembrolizumab (Keytruda) is a humanized monoclonal anti-PD1 antibody that has been extensively investigated in numerous malignancies...

Early detection of hepatocellular carcinoma (HCC) is critical for successful treatment and favorable prognosis. To identify novel HCC biomarkers, we used the WHV/c-myc transgenic (Tg) mice, an animal model of hepatocarcinogenesis. By analyzing their gene expression profiling, we investigated differentially expressed genes in livers of wild-type and Tg mice. The cytochrome P450, family 17, subfamily A, polypeptide 1 (CYP17A1), a hepatic P450 enzyme, was revealed to be overexpressed in the liver tissues of Tg mice at both preneoplastic and neoplastic stages...

Several indices have been proposed to evaluate the systemic inflammatory response (SIR), which has been reported to be a useful prognostic factor in various types of cancer. We investigated the usefulness of the Glasgow Prognostic Score (GPS), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as prognostic factors in patients with advanced hepatocellular carcinoma (HCC) with extrahepatic metastasis (stage IVB). Between April, 1997 and March, 2013, a total of 434 HCC patients who developed extrahepatic metastasis were enrolled in the present study...

Solid organ transplantation has become the therapy of choice for patients with end-stage organ disease. The frequently transplanted organs in Taiwan include liver, kidney, heart, and lung, and the success rate has improved significantly worldwide for the past decades. However, organ recipients are known to be at a higher risk of post-transplant infections and de novo cancer due to immunosuppression and oncogenic viral infections. Organ recipients are known to be at a two- to fourfold increased risk of cancer and the risks are particularly high for malignancies caused by viral infections, including post-transplant lymphoproliferative disorders via Epstein-Barr virus, Kaposi sarcoma via Kaposi sarcoma herpesvirus, anogenital cancers via human papillomavirus, and hepatocellular carcinoma via hepatitis B and C virus...

OBJECTIVE: Homeopathic nosodes have seldom been scientifically validated for their anticancer effects. This study was conducted to examine if a recently developed hepatitis C nosode has demonstrable anticancer potential in cancer cells in vitro. METHODS: Anticancer effects of Hepatitis C 30C (Hep C 30), if any, were initially tested on three cancer cell lines, HepG2 (liver cancer), MCF-7 (breast cancer) and A549 (lung cancer) and one normal liver cell line WRL-68 cells and subsequently a more thorough study using further scientific protocols was undertaken on HepG2 cells (against WRL-68 cells as the normal control) as HepG2 cells showed better anticancer response than the other two...

Hepatocellular carcinoma (HCC) is the predominant primary liver cancer in many countries and is the third most common cause of cancer-related death in the Asia-Pacific region. The incidence of HCC is higher in men and in those over 40 years old. In the Asia-Pacific region, chronic hepatitis B virus and hepatitis C virus infections are the main etiological agents; in particular, chronic hepatitis B infection (CHB) is still the major cause in all Asia-Pacific countries except for Japan. Over the past two decades, the incidence of HCC has remained stable in countries in the region except for Singapore and Hong Kong, where the incidence for both sexes is currently decreasing...

Metastasized lung and liver cancers cause over 2 million deaths annually, and are amongst the top killer cancers worldwide. Morinda citrifolia (Noni) leaves are traditionally consumed as vegetables in the tropics. The macro and micro effects of M. citrifolia (Noni) leaves on metastasized lung cancer development in vitro and in vivo were compared with the FDA-approved anti-cancer drug Erlotinib. The extract inhibited the proliferation and induced apoptosis in A549 cells (IC50 = 23.47 μg/mL) and mouse Lewis (LL2) lung carcinoma cells (IC50 = 5...

BACKGROUND: Hepatitis C virus (HCV) infection is associated with hepatocellular carcinoma and non-Hodgkin's lymphoma. In 2009, MD Anderson established the first US clinic for treating HCV-infected cancer patients, where we observed an unexpectedly large number of patients with head and neck cancers (HNCs). We sought to determine whether HCV is associated with HNCs. METHODS: In this case-control study, medical records of cancer patients tested for HCV antibodies at our center from 2004 through 2014 were identified...
