Chronic infection with the hepatitis B virus has been linked epidemiologically to the development of hepatocellular carcinoma for more than 30 years. Although the mechanisms by which chronic hepatitis B viral infection results in hepatocellular carcinoma are unclear, there is good evidence that the virus itself exerts a direct hepatocarcinogenic effect, and this has implications for prevention....

Hepatocellular carcinoma has a decisive influence on the prognosis of cirrhotic patients, and the use of imaging modalities is essential for the screening, diagnosis and treatment of hepatocellular carcinoma. Ultrasound plays a major role among them, because it provides real-time and non-invasive observation by a simple and easy technique. In addition, ultrasound-guided needle puncture methods ...

A model of hepatic dysfunction in vivo has been developed in rabbits to determine the effects of sublethal hepatocellular necrosis upon doxorubicin pharmacology. Eight New Zealand white rabbits were given 3 mg/kg doxorubicin i.v. Plasma doxorubicin and metabolite pharmacokinetics were determined and toxicity assessed by nadir complete blood counts. Hepatic function was assessed by the pulmonary...

Inflammatory pseudotumor of the liver is a rare tumor. It has variable clinical presentations and image findings. It can mimic benign or malignant hepatic tumors, and may be difficult to diagnose. We present a case in which a hepatic inflammatory pseudotumor was misdiagnosed as hepatocellular carcinoma because the tumor presented a typical enhancing profile and morphology of hepatocellular carc...

Hepatocellular carcinoma has a poor prognosis due to its rapid development and early metastasis. In this report, we characterized the metabolic features of hepatocellular carcinoma using a nontargeted metabolic profiling strategy based on liquid chromatography-mass spectrometry. Fifty pairs of liver cancer samples and matched normal tissues were collected from patients having hepatocellular car...

Both transforming growth factor-β (TGF-β) and parathyroid hormone-related protein (PTHrP) regulate important cellular processes, such as apoptosis in the development of hepatocellular carcinoma. However, the mechanisms of regulation of PTHrP by TGF-β are largely unknown. We hypothesized that TGF-β regulates the expression of PTHrP protein through a post-translational mechanism. Using hepatocell...

BACKGROUND AND OBJECTIVES Evidence suggests that sustained virologic response to interferon treatment decreases incidence of hepatocellular carcinoma in patients with hepatitis C virus cirrhosis. This study was designed to compare the incidence of hepatocellular carcinoma among cirrhotic patients exposed to interferon based treatment with or without achieving a sustained virological response, i...

Transcription factor AP-2α is involved in many types of human cancers, but its role in hepatocellular carcinogenesis is largely unknown. In this study, we found that expression of AP-2α was low in 40% of human hepatocellular cancers compared with adjacent normal tissues by immunohistochemical analysis. Moreover, AP-2α expression was low or absent in hepatocellular cancer cell lines (HepG2, Hep3...

background: kinesin spindle protein (ksp) plays a critical role in mitosis. inhibition of ksp function leads to cell cycle arrest at mitosis and ultimately to cell death. the aim of this study was to suppress ksp expression by specific small-interfering rna (sirna) in hep3b cells and evaluate its anti-tumor activity. methods: three sirna targeting ksp (ksp-sirna #1-3) and one mismatched-sirna (...

introduction since directly acting antivirals (daas) for treatment of hepatitis c virus (hcv) were introduced, conflicting data emerged about the risk of hepatocellular carcinoma (hcc) after interferon (ifn)-free treatments. we present a case of recurrent, extra-hepatic hcc in a liver-transplanted patient soon after successful treatment with daas, along with a short review of literature. conclu...
