BACKGROUND: Peroxisome proliferator-activated receptor alpha (PPARA) is a major regulator of fatty acid oxidation and severe hepatic steatosis occurs during acute fasting in Ppara-null mice. Thus, PPARA is considered an important mediator of the fasting response; however, its role in other fasting regiments such as every-other-day fasting (EODF) has not been investigated. METHODS: Mice were pre-conditioned using either a diet containing the potent PPARA agonist Wy-14643 or an EODF regimen prior to acute fasting...

The role of adaptive immunity in early cancer development is controversial. Here we show that chronic inflammation and fibrosis in humans and mice with non-alcoholic fatty liver disease is accompanied by accumulation of liver-resident immunoglobulin-A-producing (IgA(+)) cells. These cells also express programmed death ligand 1 (PD-L1) and interleukin-10, and directly suppress liver cytotoxic CD8(+) T lymphocytes, which prevent emergence of hepatocellular carcinoma and express a limited repertoire of T-cell receptors against tumour-associated antigens...

BACKGROUND AND AIM: Peroxisome proliferator-activated receptor alpha (PPARα) is a molecular target of various fibrate drugs clinically used to lower serum lipids. However, the tissue-specific functions of PPARα remain to be elucidated. This study aimed to explore the tissue-specific functions of PPARα in response to Wy-14643. METHODS: A hepatocyte-specific Ppara knockout mouse line was used to explore the impact of hepatic PPARα activity on the systemic response to treatment with the potent PPARα agonist Wy-14643...

The liver-enriched transcription factor Forkhead Box A2 (FOXA2) has been reported to be involved in bile acid homeostasis and bile duct development. However, the role of FOXA2 in liver fibrogenesis remains undefined. In this study, we found that the abundance of FOXA2 was significantly lower in fibrotic livers of patients and mice treated with CCl4 than in controls. Interestingly, the expression level of FOXA2 decreased in hepatocytes, whereas FOXA2 was elevated in hepatic stellate cells (HSCs) of mouse fibrotic livers...

BACKGROUND: Currently, the treatment of large hepatocellular carcinoma (HCC) is still a challenging problem. Transcatheter arterial chemoembolization (TACE) is the main treatment for intermediate end-stage HCC, while it is only a palliative and not a curative treatment due to the existence of residual tumors, and radiofrequency ablation (RFA) has limitations in complete ablation of large HCC. We hypothesized that TACE combined with simultaneous RFA (herein referred to as TACE + RFA) could improve the efficacy and survival of large HCC...

Hepatocellular carcinoma (HCC) is the second leading cause of death by cancer worldwide. Resection and liver transplantation are the gold standards, but only a minority of people are eligible. Percutaneous ablation therapies, such as microwave ablation (MWA), have consequently been developed. There is a lack of guidelines regarding the treatment of HCCs in end-stage renal disease (ESRD) patients. Here, we report the case of a 67-year-old patient who was undergoing peritoneal dialysis (PD) for chronic congestive heart failure and who presented with an HCC while undergoing PD...

Interventional embolization is a popular minimally invasive vascular therapeutic technique and has been widely applied for hepatocellular carcinoma (HCC) therapy. However, harmful effects caused by transcatheter arterial chemoembolization (TACE) and radioembolization, such as the toxicity of chemotherapy or excessive radiation damage, are serious disadvantages and significantly reduce the therapeutic efficacy. Here, a synergistic therapeutic strategy combined transcatheter arterial embolization and magnetic ablation (TAEMA) by using PLGA-magnetic microspheres (MMs) has been successfully applied to orthotopic VX2 liver tumors of rabbits...

β-carotene oxygenase 2 (BCO2) is a carotenoid cleavage enzyme located in the inner mitochondrial membrane. Ablation of BCO2 impairs mitochondrial function leading to oxidative stress. Herein, we performed a targeted metabolomics study using ultrahigh performance liquid chromatography-tandem mass spectroscopy and gas chromatography-mass spectroscopy to discriminate global metabolites profiles in liver samples from six-week-old male BCO2 systemic knockout (KO), heterozygous (Het), and wild type (WT) mice fed a chow diet...

Coiled-coil domain containing 134 (CCDC134), a characterized secreted protein, may serve as an immune cytokine and illustrates its potent antitumor effects by augmenting CD8+ T-cell-mediated immunity. Additionally, CCDC134 may also act as a novel regulator of human alteration/deficiency in activation 2a, and be involved in the p300-CBP-associated factor complex and affect its acetyltransferase activity. To clarify the biological and pathological function of CCDC134, the present study generated a viable and fertile Ccdc134fl/fl mouse strain that allowed temporal and spatial control of gene ablation...

REVIEW
H L Lewis, M A Ghasabeh, P Khoshpouri, I R Kamel, T M Pawlik
Objective criteria to measure tumor response are a key tenet for assessment of treatment efficacy when evaluating a therapeutic modality. Several response criteria have been proposed including the Response Evaluation Criteria in Solid Tumors (RECIST), modified RECIST (mRECIST), RECIST 1-1, and European Association for the Study of the Liver (EASL) guidelines. Response following loco-regional therapies (LRT) can be particularly difficult to assess as post-treatment changes may not always relate to changes in lesion size...

BACKGROUND: Preservation of hepatic parenchyma is important in liver surgery to prevent postoperative liver failure and according to some reports it could offer a prolonged survival and lower recurrence rates compared to major hepatectomies in patients with colorectal liver metastases. However, laparoscopic parenchyma-preserving liver resections can be technically challenging. The aim of this video is to illustrate the concept of laparoscopic parenchymal-preserving liver resections after conversion chemotherapy with targeted therapy...

BACKGROUND: Sorafenib is the recommended treatment for patients with advanced hepatocellular carcinoma. We aimed to compare the efficacy and safety of sorafenib to that of selective internal radiotherapy (SIRT) with yttrium-90 ((90)Y) resin microspheres in patients with hepatocellular carcinoma. METHODS: SARAH was a multicentre, open-label, randomised, controlled, investigator-initiated, phase 3 trial done at 25 centres specialising in liver diseases in France. Patients were eligible if they were aged at least 18 years with a life expectancy greater than 3 months, had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, Child-Pugh liver function class A or B score of 7 or lower, and locally advanced hepatocellular carcinoma (Barcelona Clinic Liver Cancer [BCLC] stage C), or new hepatocellular carcinoma not eligible for surgical resection, liver transplantation, or thermal ablation after a previously cured hepatocellular carcinoma (cured by surgery or thermoablative therapy), or hepatocellular carcinoma with two unsuccessful rounds of transarterial chemoembolisation...

Hepatocellular carcinoma (HCC) is a frequent neoplasia and a leading cause of inflammation-related cancer mortality. Despite most HCC arise from persistent inflammatory conditions; pathways linking chronic inflammation to cancer development are still incompletely elucidated. We dissected the role of adaptive immunity in the Mdr2-/- mouse, a model of inflammation-associated cancer, in which ablation of adaptive immunity has been induced genetically (Rag2-/-Mdr2-/- and μMt-Mdr2-/- mice) or with in vivo treatments using lymphocyte-specific depleting antibodies (anti-CD20 or anti-CD4/CD8)...
