New 3-Aryl-2-(2-Thienyl)acrylonitriles with High Activity against Hepatoma Cells
2021
New 2-(thien-2-yl)-acrylonitriles with putative kinase inhibitory activity were prepared and tested for their antineoplastic efficacy in hepatoma models. Four out of the 14 derivatives were shown to inhibit hepatoma cell proliferation at (sub-)micromolar concentrations with IC50 values below that of the clinically relevant multikinase inhibitor sorafenib, which served as a reference. Colony formation assays as well as primary in vivo examinations of hepatoma tumors grown on the chorioallantoic membrane of fertilized chicken eggs (CAM assay) confirmed the excellent antineoplastic efficacy of the new derivatives. Their mode of action included an induction of apoptotic capsase-3 activity, whil…
Deconvolution of the cellular origin in hepatocellular carcinoma: Hepatocytes take the center stage.
2016
The expression of biliary/progenitor markers by hepatocellular carcinoma (HCC) is often associated with poor prognosis and stem cell-like behaviors of tumor cells. Hepatocellular adenomas (HCA) also often express biliary/progenitor markers and frequently act as precursor lesions for HCC. However, the cell of origin of HCA and HCC that expresses these markers still remains unclear. Therefore, to evaluate if mature hepatocytes give rise to HCA and HCC tumors, and to understand the molecular pathways involved in tumorigenesis, we lineage-labeled hepatocytes by injecting adeno-associated virus (AAV) containing thyroxine-binding globulin (TBG) promoter driven-Cre into RosaYFP mice. Yellow fluore…

Hepatocellular carcinoma and direct-acting antivirals: A never ending story?

Systemic treatment of HCC in special populations
2020
Summary Recent years have seen significant progress in the systemic treatment of hepatocellular carcinoma (HCC), including the advent of immunotherapy. While several large phase III trials have provided the evidence for a multi-line treatment paradigm, they have focused on a highly selected group of patients by excluding potentially confounding comorbidities. As a result, high quality evidence for the systemic treatment of HCC in patients with various comorbidities is missing. This review summarises current knowledge on the use of approved medicines in patients with HIV, autoimmune disease, cardiovascular disease, diabetes, fibrolamellar HCC, mixed HCC-cholangiocarcinoma, decompensated cirr…
Hepatic B cell leukemia-3 promotes hepatic steatosis and inflammation through insulin-sensitive metabolic transcription factors.
2016
Background & Aims The pathomechanisms underlying non-alcoholic fatty liver disease (NAFLD) and the involved molecular regulators are incompletely explored. The nuclear factor-kappa B (NF-κB)-cofactor gene B cell leukemia-3 ( Bcl-3 ) plays a critical role in altering the transcriptional capacity of NF-κB – a key inducer of inflammation – but also of genes involved in cellular energy metabolism. Methods To define the role of Bcl-3 in non-alcoholic steatohepatitis (NASH), we developed a novel transgenic mouse model with hepatocyte-specific overexpression of Bcl-3 ( Bcl-3 Hep ) and employed a high-fat, high-carbohydrate dietary feeding model. To characterize the transgenic model, deep RNA seque…
Antiviral therapy in the palliative setting of HCC (BCLC-B and -C)
2020
The potential impact of direct-acting antivirals (DAAs) in patients with Barcelona Clinic Liver Cancer (BCLC)-B/C stage hepatocellular carcinoma (HCC) is understudied. Patients with HCC have been systematically excluded from randomised controlled trials evaluating the effectiveness of DAAs. Thus, the benefits of DAAs in patients with HCC are less well defined. The presence of active HCC before the initiation of DAA treatment is reported to be a predictor of DAA failure, and studies in patients without HCC have demonstrated that improvements in cirrhosis complications were lower or absent after DAA failure. Even if viral eradication is achieved using DAAs, reversal of liver function impairme…
Adjuvant MUC vaccination with tecemotide after resection of colorectal liver metastases: a randomized, double-blind, placebo-controlled, multicenter …
2020
ABSTRACT Resection of colorectal liver metastases (CRLM) is a potential curative treatment for patients with metastatic colorectal cancer (mCRC) with liver-limited disease (LLD). Although long-term survival improved considerably within the last decades, high recurrence rates of 50-75% after resection remain a major challenge.Tecemotide (L-BLP25) is an antigen-specific cancer vaccine inducing immunity against mucin-1 (MUC1). The LICC trial aimed to improve survival in patients with mCRC after R0/R1 resection of CRLM. LICC was a binational, randomized, double-blind, placebo-controlled, multicenter phase 2 study including patients with R0/R1 resected CRLM without evidence of metastatic disease…
A case of infective colitis due to Yersinia enterocolitica complicated by microliver abscesses mimicking multiple liver occult metastases: a case rep…
2021
Abstract Background We report an unusual case of infective colitis by Yersinia enterocolitica complicated by microliver abscesses mimicking multiple liver metastases in a 79 yr old female without any risk factors for bacteriaemia by this pathogen. Case presentation The patient was admitted to the Internal Medicine with Stroke Care ward of University Policlinico “P. Giaccone” in Palermo because of the appearance of diarrhoea. After the antimicrobial treatment for infective colitis, the clinicians observed a persistently increased white blood cells (WBC) count and multiple hepatic lesions; after having excluded any neoplastic disease and inflammatory bowel disease (IBD), blood cultures positi…
