Evaluation of Selenium Nanoparticles and Doxorubicin Effect Against Hepatocellular Carcinoma Rat Model Cytogenetic Toxicity and DNA Damage

Publication date: Available online 25 July 2018Source: Toxicology ReportsAuthor(s): Omaima M. Abd-Elmoneim, Abeer H. Abd El-Rahim, Naglaa A. HafizAbstractThe present study aimed to demonstrate the potent role of nanoselenium and Doxorubicin in retrogression of genotoxicity induced in hepatocellular carcinoma rat model by studying chromosomal aberration, micronuclei formation, DNA fragmentation as well as comet assay. Male rats hepatocellular carcinoma model were treated wih Se-Nanopartcles, Doxurobicin and the combination of both. The results revealed the protective effect of nanoselenium, Doxorubicin and their combination on bone marrow cytogenetic toxicity by decreasing chromosomal aberrations and micronuclei formation as well as their effects on rat's liver by decreasing DNA damage. Nevertheless, the treatment with nanoselenium either alone or in combination with Doxorubicin was more effective than treatment with doxorubicin alone.

Conclusions: Our findings suggested that Dulcitol acted as a SIRT1 inhibitor, inducing apoptosis and inhibiting proliferation, migration and invasion of HepG2 cells and its modulatory mechanism seemed to be associated with regulation of MMPs, SIRT1/p53 pathways.Graphical abstractSchematic diagram of the proposed mechanisms of Dulcitol-induced apoptosis and anti-metastasis in hepatocellular carcinoma in vivo and in vitro.

In this study, we aimed to explore the efficacy and safety profile of apatinib monotherapy, or combined with chemotherapy or endothelial growth factor receptor (EGFR)-TKI in heavily pretreated non-small cell lung cancer (NSCLC) patients with brain metastases. We performed a retrospective analysis for relapsed NSCLC patients with brain metastases from our institute, whom received apatinib (250mg or 500mg p.o. qd) monotherapy, or combination with EGFR-TKI or chemotherapy as second- or more line systemic therapy until disease progression or unacceptable toxicity occurred. The objective response rate (ORR), disease control rat...

Authors: Han T, Yang X, Zhang Y, Li G, Liu L, Chen T, Zheng Z Abstract Transcatheter arterial chemoembolization (TACE) plays an important role in the treatment of unresectable liver cancer. We conducted this meta-analysis to compare the clinical safety and efficacy of conventional TACE (C-TACE) and drug-eluting beads (DEB)-TACE. A search for those procedures was performed using the PubMed, EMBASE, and Cochrane Library databases. A meta-analysis of patients who underwent C-TACE or DEB-TACE was conducted. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. Of 334 studies, 30 were analyzed. The compl...

AbstractBackgroundThe purpose of this study is to compare the clinical outcomes of laparoscopic liver resection versus open liver resection for recurrent hepatocellular carcinoma (RHCC).MethodsPublished studies which investigated laparoscopic versus open liver resection for RHCC were identified, and meta-analysis was used for statistical analysis.ResultsSix studies were analyzed by meta-analysis method, and cumulative 335 cases were included in this study. Laparoscopic liver resection was performed in 145 cases, and open liver resection was performed in 190 cases. Meta-analysis showed that there was no difference in operat...

AbstractPurposeTo determine the diagnostic performance of intravoxel incoherent motion (IVIM) parameters to predict tumor recurrence after hepatectomy in patients with hepatitis B virus (HBV) –related hepatocellular carcinoma (HCC).Materials and methodsOne hundred and fifty-seven patients (mean age 52.54  ± 11.32 years, 87% male) with surgically and pathologically confirmed HCC were included. Regions of interests were drawn including the tumors by two independent radiologists. ADC and IVIM-derived parameters (true diffusion coefficient [D]; pseudodiffusion coefficient [D*]; pseudodiffusion f...

AbstractObjectiveTo study lipiodol deposition in portal vein tumour thrombus (PVTT) in predicting the treatment outcome of hepatocellular carcinoma (HCC) patients after transarterial chemoembolisation (TACE).MethodsWe retrospectively reviewed data from 379 HCC patients with PVTT who underwent TACE as the initial treatment at Sun Yat-Sen University Cancer Center from January 2008 to December 2015. Patients were grouped by positive and negative lipiodol deposition based on the extent of lipiodol deposition in PVTT. The overall survival (OS) and progression-free survival (PFS) were compared between negative and positive lipio...

Authors: Liu N, Feng J, Lv Y, Liu Q, Deng J, Xia Y, Guo C, Zhou Y Abstract The accumulation of toxic bile acids (BAs) is closely related to liver injury, inflammation and tumorigenesis. The aim of the present study was to determine the role of the serum BA spectrum in the diagnosis and progression of liver cirrhosis. This was a prospective observational study involving patients with chronic hepatitis (n=23), liver cirrhosis (n=101), and cirrhosis complicated with hepatocellular carcinoma (CC-HCC; n=56). The 6-month survival of cirrhotic patients was recorded after blood collection. Comparisons of serum total BAs an...

Authors: Chen B, Jin S, Bai B, Li Z, Ni C, Liu Y Abstract Interferon-stimulated gene 15 (ISG15) serves a crucial role in hepatocellular carcinoma (HCC) progression. The present study explored the effect of ISG15 knockdown on the sensitivity of HCC cells to norcantharidin. The expression of ISG15 in HCC tissues and cell lines was assessed by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry. Pearson's χ2 test was conducted to analyze the correlation between the clinicopathological features and ISG15 expression of patients with HCC. In addition, HCC cells were transfected with ...

Publication date: Available online 16 October 2019Source: Journal of the Formosan Medical AssociationAuthor(s): Shih-Jer Hsu, Sheng-Shun Yang, Jia-Horng KaoAlthough interferon (IFN)-based therapy has been shown to reduce hepatocellular carcinoma (HCC) development once patients with chronic hepatitis C virus (HCV) infection achieve sustained virologic response (SVR), IFN-based therapy is limited by its multiple adverse effects, non-oral administration, and unsatisfactory SVR rate. In recent years, IFN-free all-oral direct-acting antivirals (DAAs) have replaced IFN-based therapy as the standard of care for HCV infection worl...
