Various studies have presented different approaches to direct pluripotent stem cell differentiation such as applying defined sets of exogenous biochemical signals and genetic/epigenetic modifications. Although differentiation to target lineages was successfully regulated, such conventional methods are often complicated, laborious, and not cost-effective to be employed to the large-scale production of 3D stem cell-based tissue constructs. In this study, we developed a 3D-culture platform that could realize the large-scale production of mesoderm lineage tissue constructs from embryonic stem cells (ESCs)...

Adefovir-induced hypophosphatemic osteomalacia in the context of hepatocarcinoma is rare and needs to be differentiated from metastatic hepatocarcinoma. We here report a case of severe osteomalacia whose focal uptakes of radiotracer on the Tc-MDP SPECT/CT images mimicked that of metastatic hepatocarcinoma.

Previous studies have shown that the ethanolic extracts from Sophora moorcroftiana seeds (ee-Sms) have in vitro anticancer properties. The anti-proliferation effects of ee-Sms on HepG2 cells were assessed by MTT assay and cell cycle analysis. Total cell proteins were separated by two-dimensional electrophoresis (2-DE), and protein spots with more than two-fold difference were analysed by MALDI-TOF/TOF-MS. MTT assay showed that the anti-proliferation of ee-Sms demonstrates dose- and time dependently. HepG2 cells were treated with ee-Sms at 1...

The tyrosine kinase inhibitor erlotinib targets the receptor of epidermal growth factor (EGFR) involved in development of hepatocellular carcinoma (HCC). Although inefficient in established HCC, erlotinib has been recently proposed for HCC chemoprevention. Since Cyp3A4 and Cyp1A2 enzymes metabolize erlotinib in the liver, the insights into the mechanisms of erlotinib effects on liver cells with maintained drug metabolizing activity are needed. We applied erlotinib to both commercially available (SNU398, Huh7) and established in Austria HCC cell lines (HCC-1...

Recent studies indicate that horizontal transfer of genetic material can act as a communication tool between heterogenous populations of tumour cells, thus altering the chemosensitivity of tumour cells. The present study was designed to check whether the horizontal transfer of miRNAs released by cisplatin resistant (Cp-r) Hepatocarcinoma cells can alter the sensitivity of cervical cancer cells. For this exosomes secreted by cisplatin resistant and cisplatin sensitive HepG2 cells (EXres and EXsen) were isolated and characterised...

Hepatitis C virus (HCV) induces the expression of the genes of proinflammatory cytokines, the excessive production of which may cause cell death, and contribute to development of liver fibrosis and hepatocarcinoma. The relationship between cytokine production and metabolic disorders in HCV-infected cells remains obscure. The levels of biogenic polyamines, spermine, spermidine, and their precursor putrescine, may be a potential regulator of these processes. The purpose of the present work was to study the effects of the compounds which modulate biogenic polyamines metabolism on cytokine production and HCV proteins expression...

Fifteen novel 1,2,3-triazole derivatives were prepared in series of synthetic steps starting from 4-amino-5-hydrazino-4H-1,2,4-triazole-3-thiol 1. The structures of the obtained compounds were verified through micoanalytical and spectral data. All the compounds were screened for their anticancer activity against liver human cancer cell lines (HEPG2) using Doxorubicin as standard. The most promising triazolothiadiazine derivative 12 was further tested for its degree of toxicity by estimating the median lethal dose (LD 50) and its antitumor activity through inhibiting the angiogenesis and progression of tumor against diethylnitrosamine (DENA)/CCl4 induced hepatocellular carcinoma (HCC) in rats...

Chronic liver diseases are one of the major causes of mortality worldwide. It can manifest through many different forms including chronic virus infection, alcohol abuse, metabolic syndromes such as non-alcoholic fatty liver disease and non-alcoholic steatohepatitis. At early stages, the liver can repair the damage produced by the insult. However, upon continuous damage, the accumulation of molecules triggers fibrosis, which subsequently progresses towards cirrhosis and, ultimately, hepatocarcinoma. Early diagnosis of liver disease and a proper staging of fibrosis are crucial in therapy since drugs are only effective at incipient and intermediate stages of the disease...

The progression of cancer is often accompanied by changes in the mechanical properties of an extracellular matrix. However, limited efforts have been made to reproduce these biological events in vitro. To this end, this study demonstrates that matrix remodeling caused by matrix metalloproteinase (MMP)-1 regulates phenotypic activities and modulates radiosensitivity of cancer cells exclusively in a 3D matrix. In this study, hepatocarcinoma cells are cultured in a collagen-based gel tailored to present an elastic modulus of ≈4...

Apurinic/apyrimidinic endonuclease/redox element 1 (APE1/Ref-1) is a pervasive multifunctional protein required in the DNA base extraction repair (BER) pathway and a noteworthy reducing-oxidizing (redox) factor that upgrades the authoritative of various transcription components to DNA. Cyclin-dependent kinases (CDKs) assume a key part in directing the movement of the cell-cycle. The present study evaluates the synergistic efficacy of using licochalcone B (LCB) and fullerene C60 (FnC60) nanoparticles against diethylnitrosamine (DEN)-induced hepatocarcinoma (HCC) in rats...

Mitochondrial oxidation of nutrients is tightly regulated in response to the cellular environment and changes in energy demands. In vitro studies evaluating the mitochondrial capacity of oxidizing different substrates are important for understanding metabolic shifts in physiological adaptations and pathological conditions, but may be influenced by the nutrients present in the culture medium or by the utilization of endogenous stores. One such influence is exemplified by the Crabtree effect (the glucose-mediated inhibition of mitochondrial respiration), as most in vitro experiments are performed in glucose-containing media...

The solute carrier family 13 member 5 (SLC13A5), a sodium-coupled citrate transporter, plays a key role in importing citrate from the circulation into liver cells. Recent evidence has revealed that SLC13A5 deletion protects mice from high-fat diet-induced hepatic steatosis and that mutation of the SLC13A5 orthologues in D. melanogaster and C. elegans promotes longevity. However, despite the emerging importance of SLC13A5 in energy homeostasis, whether perturbation of SLC13A5 affects the metabolism and malignancy of hepatocellular carcinoma is unknown...

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...

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)...
