PURPOSE To investigate the potential value of magnetic resonance (MR) elastography and diffusion-weighted (DW) MR imaging in the detection of microstructural changes of murine colon tumors during growth and antivascular treatment. MATERIALS AND METHODS The study was approved by the regional ethics committee for animal care. Sixty Balb-C mice, bearing(More)
OBJECTIVE Chronic liver diseases, including cirrhosis, may develop in obese patients. Steatosis and non-alcoholic steatohepatitis (NASH) are risk factors for progression to fibrosis. To date, diagnosis of steatosis and NASH relies on liver biopsy. The aim of the study was to identify serum markers of steatosis and NASH in obese patients using SELDI-TOF(More)
BACKGROUND While outcome continuously improves after liver transplantation, sepsis remains the leading cause of early postoperative mortality. Diagnosis of infections remains particularly difficult in these patients. This study used plasma profiling coupling Proteinchip array with surface-enhanced laser desorption ionization time-of-fly mass spectrometry to(More)
BACKGROUND Metabolic syndrome (MS) is an emerging risk factor in hepatocellular carcinoma (HCC). HCC related to MS may occur either in advanced fibrosis or before the development of cirrhosis, suggesting involvement of different molecular pathways according to the features of background liver. OBJECTIVE To investigate genomic aberrations in HCC related to(More)
MALDI imaging mass spectrometry (MALDI IMS) is a powerful tool for comprehending the spectrum of peptides/proteins expressed in tissue sections. The aim of the present study was to investigate, using MALDI IMS, the proteome of hepatocellular carcinomas (HCC) and to compare it with peritumoral cirrhosis so as to characterize new biomarkers of HCC. Frozen(More)
BACKGROUND & AIMS Prothrombin induced by vitamin K absence-II (PIVKA-II) is a diagnostic and surveillance marker for HCC mainly used in Asia, and has also been shown to be a predictor of microvascular invasion (MVI), a major prognostic factor in HCC. However, experience with PIVKA-II in Europe remains limited. METHODS In a French cohort, we conducted a(More)
Galunisertib (LY2157299) is a selective ATP-mimetic inhibitor of TGF-β receptor (TβR)-I activation currently under clinical investigation in hepatocellular carcinoma (HCC) patients. Our study explored the effects of galunisertib in vitro in HCC cell lines and ex vivo on patient samples. Galunisertib was evaluated in HepG2, Hep3B, Huh7, JHH6 and SK-HEP1(More)
Studies suggest that metformin, widely used for treating Type 2 diabetes, possesses innate antineoplastic properties. For metabolic syndrome patients with hepatocellular carcinoma (HCC), metformin may provide antitumoral effects. We evaluated the impact of metformin on tumour growth and visceral fat composition using relevant preclinical models of metabolic(More)
