Occult hepatitis B virus infection

2000

Many studies have shown that hepatitis B virus infection may also occur in hepatitis B surface antigen-negative patients. This occult infection has been identified both in patients with cryptogenic liver disease and in patients with hepatitis C virus-related chronic hepatitis, and much evidence suggests that it may be a risk factor of hepatocellular carcinoma development. However several aspects of this occult infection remain unclear such as its prevalence and the factor(s) involved in the lack of circulating hepatitis B surface antigen. Moreover, it is uncertain whether the occult hepatitis B virus infection may contribute to chronic liver damage, considering that it is usually associated…

Tumor Necrosis Factor (TNF) Receptor 1 Signaling Downstream of TNF Receptor-associated Factor 2

1997

Like other members of the tumor necrosis factor (TNF) receptor family, p55 TNF receptor 1 (TNF-R1) lacks intrinsic signaling capacity and transduces signals by recruiting associating molecules. The TNF-R1 associated death domain protein interacts with the p55 TNF-R1 cytoplasmic domain and recruits the Fas-associated death domain protein (which directly activates the apoptotic proteases), the protein kinase receptor interacting protein, and TNF receptor-associated factor 2 (TRAF2). TRAF2 has previously been demonstrated to activate both transcription factor nuclear factor kappaB (NFkappaB) and the c-Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) pathway, which in turn stimu…

Inverse correlation between plasma oxysterol and LDL-cholesterol levels in hepatitis C virus-infected patients

2012

Background: Hepatitis C virus infection is characterised by enhanced oxidative stress, which can be measured quantitatively by plasma oxysterol concentration. These molecules may affect lipid metabolism through the activation of Liver X Receptors. Hepatitis C virus exploits host lipid metabolism to facilitate its replication and diffusion. In our study we aimed to evaluate and highlight the potential pathogenetic role of oxysterols, 7-ketocholesterol and 7-β-hydroxycholesterol, in hepatitis C virus-related lipid dysmetabolism. Methods: The study was performed in 42 patients with chronic hepatitis C (93% genotype 1b) and 38 non-alcoholic fatty liver disease patients. Plasma oxysterols 7-keto…

Copper/MYC/CTR1 interplay: A dangerous relationship in hepatocellular carcinoma

2018

Free serum copper correlates with tumor incidence and progression of human cancers, including hepatocellular carcinoma (HCC). Copper extracellular uptake is provided by the transporter CTR1, whose expression is regulated to avoid excessive intracellular copper entry. Inadequate copper serum concentration is involved in the pathogenesis of Non Alcoholic Fatty Liver Disease (NAFLD), which is becoming a major cause of liver damage progression and HCC incidence. Finally, MYC is over-expressed in most of HCCs and is a critical regulator of cellular growth, tumor invasion and metastasis. The purpose of our study was to understand if higher serum copper concentrations might be involved in the prog…
