Cationic Solid Lipid Nanoparticles (SLN) for shNupr1 plasmid delivery in the treatment of hepatocellular carcinoma (HCC)

Induction of apoptosis by the proteasome inhibitor MG132 in human HCC cells: Possible correlation with specific caspase-dependent cleavage of β-caten…
2004
Proteasome inhibitors, like MG132, can exert cell growth inhibitory and apoptotic effects in different tumor types. The apoptotic mechanism of these compounds involves the activation of the effector caspases. beta-catenin, also an oncogene, represents one of the substrates of these proteases, but the consequences of its cleavage are poorly understood. We investigated its function during apoptosis induced by MG132 in three hepatocellular carcinoma (HCC) cell lines, endowed (HepG2 and HuH-6) or not (HA22T/VGH) with activating mutations of beta-catenin. Induction of apoptosis was associated with cell growth inhibition, accumulation of the cells at the G(2)/M phases of the cell cycle, as well a…
Incidence of new foci of hepatocellular carcinoma (HCC) in patients who underwent radiofrequency ablation of HCC: Role of multidetector CT

Spectrum of liver lesions hyperintense on hepatobiliary phase: an approach by clinical setting.
2021
AbstractHepatobiliary MRI contrast agents are increasingly being used for liver imaging. In clinical practice, most focal liver lesions do not uptake hepatobiliary contrast agents. Less commonly, hepatic lesions may show variable signal characteristics on hepatobiliary phase. This pictorial essay reviews a broad spectrum of benign and malignant focal hepatic observations that may show hyperintensity on hepatobiliary phase in various clinical settings. In non-cirrhotic patients, focal hepatic observations that show hyperintensity in the hepatobiliary phase are usually benign and typically include focal nodular hyperplasia. In patients with primary or secondary vascular disorders, focal nodul…
CEUS LI-RADS: a pictorial review
2020
AbstractContrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic tool in the imaging work-up of cirrhotic patients at risk for developing hepatocellular carcinoma (HCC). In particular, CEUS Liver Imaging Reporting and Data System (LI-RADS) provides standardized terminology, interpretation, and reporting for the diagnosis of HCC. The aim of this pictorial essay is to illustrate CEUS features of nodules discovered at US in cirrhotic liver according to LI-RADS categorization.
Hazardous air pollutants and primary liver cancer in Texas.
2016
The incidence of hepatocellular carcinoma (HCC), the most common primary liver cancer, is increasing in the US and tripled during the past two decades. The reasons for such phenomenon remain poorly understood. Texas is among continental states with the highest incidence of liver cancer with an annual increment of 5.7%. Established risk factors for HCC include Hepatitis B and C (HBV, HCV) viral infection, alcohol, tobacco and suspected risk factors include obesity and diabetes. While distribution of these risk factors in the state of Texas is similar to the national data and homogeneous, the incidence of HCC in this state is exceptionally higher than the national average and appears to be di…
Article Commentary: Clinical Medicine: Endocrinology and Diabetes: Insulin Resistance–-a Link between Inflammation and Hepatocarcinogenesis?
2009
The incidence of hepatocellular carcinoma (HCC) is increasing world wide. The risk factors for the development of HCC include liver cirrhosis, chronic alcohol intake, and chronic viral hepatitis. These conditions are associated with inflammation, liver cell injury, and oxidative stress. The signaling pathways that contribute to liver cell injury have been shown to also promote insulin resistance in hepatocytes. On the other hand, obesity and diabetes have been suggested as risk factors for the development of chronic liver disease and HCC. The molecular mediators (e.g. stress kinases) and signaling pathways that contribute to cellular injury, proliferation and insulin resistance are also ac…
Impact of SARS-CoV-2 Pandemic on the Management of Patients with Hepatocellular Carcinoma.
2022
Worldwide, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) significantly increases mortality and morbidity. The Coronavirus Disease 2019 (COVID-19) outbreak has had a considerable impact on healthcare systems all around the world, having a significant effect on planned patient activity and established care pathways, in order to meet the difficult task of the global pandemic. Patients with hepatocellular carcinoma (HCC) are considered a particularly susceptible population and conceivably at increased risk for severe COVID-19 because of two combined risk factors: chronic advanced liver disease and HCC itself. In these challenging times, it is mandatory to reshape clinical pra…
Role of LI-RADS Indeterminate Observations in the Risk of Hepatocellular Carcinoma after HCV Eradication with Direct-Acting Antivirals.
2022
Purpose: To assess whether HCC (LR-5) occurrence may be associated with the presence of Liver Imaging Reporting and Data System (LI-RADS) indeterminate observations in patients with hepatitis C virus infection treated with direct acting antiviral (DAA) therapy. Materials and methods: This retrospective study included patients with HCV-related cirrhosis who achieved sustained virologic response (SVR) after DAA therapy between 2015 and 2019 and submitted to CT/MRI follow-ups with a minimum interval time of six months before and after DAA. Two blinded readers reviewed CT/MRI to categorize observations according to LI-RADS version 2018. Differences in rate of LI-RADS 5 observations (i.e., LR-5)…
