RATIONALE: Ectopic splenic autotransplantation refers to the heterotopic autotransplantation of splenic tissue and no treatment is necessary for it when patient is asymptomatic. Its incidence rate is reported up to 67% among patients with a history of splenic trauma and splenic surgery. The diagnosis of it before operation is really difficult, and it is easy to mimic as other tumors. PATIENT CONCERNS: We reported a 42-year-old man with hepatic splenosis, with history of splenectomy for traumatic splenic rupture 16 years ago and hepatitis B&C...

This study aims to investigate in in vivo and in vitro models of nonalcoholic fatty liver disease (NAFLD) the enzymatic metabolism of α-tocopherol (vitamin E) and its relationship to vitamin E-responsive genes with key role in the lipid metabolism and detoxification of the liver. The experimental models included mice fed a high-fat diet combined or not with fructose (HFD+F) and HepG2 human hepatocarcinoma cells treated with the lipogenic agents palmitate, oleate or fructose. CYP4F2 protein, a cytochrome P-450 isoform with proposed α-tocopherol ω-hydroxylase activity, decreased in HFD and even more in HFD+F mice liver; this finding was associated with increased hepatic levels of α-tocopherol and decreased formation of the corresponding long-chain metabolites α-13-hydroxy and α-13-carboxy chromanols...

The coating of nanoparticles on materials for medical application [e.g., the coating of Fe₃O₄ nanopowder (IONP) with a carbon nanolayer] serves to protect and modify the selected biological, physical, and chemical properties of the coated material. Increases in chemical stability, changes in biocompatibility, and a modified surface structure are examples of the effects caused by the formation of carbon coatings. In the current study, Fe₃O₄ nanoparticles were coated with a carbon nanolayer (IONP@C) in a plasmochemical reactor (using radio-frequency plasma-enhanced chemical vapor deposition methods) under various experimental conditions...

Hepatocarcinoma (HCC) is the most common liver cancer with high metastasis and recurrence rate which represents extremely poor prognosis. In this study, we aimed to investigate the effects of Schisandrin B (Sch B) on HCC cells both in vitro and in vivo and to explore its underlying mechanism. We found that Sch B inhibited the proliferation of HCC cells in a dose-dependent manner as assessed by CCK-8 assay. The flow cytometric assay showed that Sch B significantly induced HCC cell apoptosis. Besides, Sch B suppressed HCC cell metastasis as detected by both wound-healing assay and transwell migration assay...

The SASH1 gene is discovered as a tumor suppressor recently. However, the molecular mechanisms of SASH1 in hepatocarcinoma (HCC) remain unclear. In present studies, we investigated the molecular mechanisms of SASH1 on cell invasion and metastasis of hepatocarcinoma in vivo and in vitro. In this study, SASH1 overexpression HCC cell lines were treated with purmorphamine (0, 0.5, 1, 2μmol/l). Western blot and qRT-PCR were used to examine the related gene expression of EMT markers and the Shh-Gli1 and PI3K/Akt-dependent pathway...

Environmental chemicals exposure is one of the primary factors for liver toxicity and hepatocarcinoma. Thioacetamide (TAA) is a well-known hepatotoxicant and could be a liver carcinogen in humans. The discovery of early and sensitive microRNA (miRNA) biomarkers in liver injury and tumor progression could improve cancer diagnosis, prognosis, and management. To study this, we performed next generation sequencing of the livers of Sprague-Dawley rats treated with TAA at three doses (4.5, 15 and 45 mg/kg) and four time points (3-, 7-, 14- and 28-days)...

Hepatitis B virus-encoded X protein (HBx) plays a critical role in HBV-related hepatocarcinoma development. In this study, we demonstrated that HBx is specifically modified by NEDD8. We found that E3 ligase HDM2 promotes NEDDylation of HBx to enhance HBx stability by preventing its ubiquitination-mediated degradation. Consistently, analysis of 160 HCC patient specimens indicated that the amount of HDM2 protein correlates with HBx protein level. We identified that HBx K91 and K95 as the key HBx NEDDylation sites and observed that the NEDDylation-deficient HBx has shorter half-life...

Hepatocarcinoma is one of the malignant cancers with significant morbidity and mortality. Immunotherapy has emerged in clinical treatment, owing to the limitation and severe side effects of chemotherapy. In the immune system, natural killer (NK) cells are important effectors required to eliminate malignant tumor cells without the limitation of major histocompatibility complex (MHC) molecule issues. Hence, treatment which could stimulate NK cells is of great interest. Here, we investigated the efficacy of the combined therapy of TT-1 (a mutant of melittin) and interferon-α (IFN-α) on NK cells and human liver cancer HepG-2/Huh7 cells in vitro and in vivo, as well as the mechanism involved...

Hepatocellular cancer is the most common type of primary liver cancer. Cirrhosis is the main risk factor that generates this malady. It has been proven that caloric restriction protocols and restricted feeding schedules are protective in experimental carcinogenic models. We tested the influence of a time-caloric restriction protocol (2 h of food access during the daytime for 18 weeks) in an experimental model of cirrhosis-hepatocarcinoma produced by weekly administration of diethylnitrosamine. Our results indicate that time-caloric restriction reduced hepatomegaly and prevented the increase in blood leukocytes promoted by diethylnitrosamine...

Ryuji Kato, Jack Uetrecht
There is increasing evidence that most idiosyncratic drug-induced liver injury (IDILI) is immune mediated, and in most cases, reactive metabolites appear to be responsible for the induction of this immune response. Reactive metabolites can cause cell damage with the release of damage-associated molecular patterns (DAMPs), which is thought to be involved in immune activation. Presumably, the reason that the liver is a common target of idiosyncratic drug reactions is because it is the major site of drug metabolism and reactive metabolite formation...

MicroRNAs (miRNAs) are endogenous non-coding regulatory RNAs involved in multiple cellular processes. Emerging evidences showed that miRNAs are involved in changing the cell surface glycosylation modification and oncogenesis. In this study, the role of miRNA-24-1 in O-GlcNAcylation and metastasis of mouse hepatocarcinoma cells was investigated. miRNAs expression array profiles were obtained from mouse hepatocarcinoma cell lines Hca-P and Hca-F with the low/high lymphatic metastasis potential, respectively. Based on the miRNAs expression array profiles, miRNA-24-1 expression was found to exhibit converse coincidence with metastasis potential, O-GlcNAc transferase (OGT) expression and O-GlcNAcylation...
