However, as a bifunctional alkylating agent, during clinical use several side effects may occur. In addition, several in vivo and in vitro studies of busulfan have shown a range of genotoxic effects including DNA strand break and inhibition of DNA synthesis. Amifostine, an organic thiophosphate compound, has been shown to exert an important cyto-protective effect in many tissues. The aim of this study was to explore whether amifostine protects against busulfan-induced genotoxicity in HepG2 cell line. Our results showed that amifostine reduced the genotoxic effects of busulfan significantly in both type of experiment conditions, as measured via comet assay. Furthermore, amifostine decreased the intracellular ROS generation induced by busulfan and also increased the intracellular GSH levels in HepG2 cells. Altogether, our results suggest a protective action of amifostine against busulfan cytotoxicity and genotoxicity via various pathways. The most protective effect was observed with amifostine when it was administrated 24 h before busulfan treatment.","PeriodicalId":49117,"journal":{"name":"Toxicology Mechanisms and Methods","volume":"27 1","pages":"52 - 57"},"PeriodicalIF":3.2,"publicationDate":"2017-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15376516.2016.1243601","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43941325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the role of Cd in oxidative stress and apoptosis is less understood. Hence, the present study was undertaken to unveil the mechanism of action. A549 cells were treated with or without Cd and cell viability was measured by MTT assay. Treatment of cells with Cd shows reduced viability in a dose-dependent manner with IC50 of 45 μM concentration. Cd significantly induces the reactive oxygen species (ROS), lipid peroxidation followed by membrane damage with the leakage of lactate dehydrogenase (LDH). Cells with continuous exposure of Cd deplete the antioxidant super oxide dismutase (SOD) and glutathione peroxidase (GSH-Px) enzymes. Further, analysis of the expression of genes involved in apoptosis show that both the extrinsic and intrinsic apoptotic pathways were involved. Death receptor marker tumor necrosis factor-α (TNF-α), executor caspase-8 and pro-apoptotic gene (Bax) were induced, while antiapoptotic gene (Bcl-2) was decreased in Cd-treated cells. Fluorescence-activated cell sorting (FACS) analysis further confirms the induction of apoptosis in Cd-treated A549 cells.","PeriodicalId":49117,"journal":{"name":"Toxicology Mechanisms and Methods","volume":"26 1","pages":"658 - 666"},"PeriodicalIF":3.2,"publicationDate":"2016-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15376516.2016.1223240","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59851622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that mice exposed to PQ had significantly longer latencies than those in the control group, with a dose-dependent manner.

Curcumol significantly inhibited neurite outgrowth and cell proliferation, but did not cause cell death at a concentration of 450 μM in differentiated PC12 cells. In addition, curcumol evoked oxidative stress and it was indicated by an elevation in reactive oxygen species (ROS) and lipid peroxidation (LPO). Although PC12 cells exhibited inhibition of the differentiation into the acetylcholine (ACh) phenotype following 450 μM curcumol exposure, there was no significant alteration in net shift toward the ACh phenotype or tyrosine hydroxylase (TH) phenotype was observed. Neural cell adhesion molecule (NCAM)/focal adhesion kinase (FAK) but not extracellular signal-regulated kinases 1 and 2 (ERK1/2) signaling was repressed by curcumol exposure in differentiated PC12 cells. Curcumol does not affect calpain activity and nuclear factor-κB (NF-κB) DNA-binding activity. These findings suggest that curcumol might be a developmental neurotoxicant and NCAM/FAK signaling pathway may play an important role in curcumol-evoked inhibition of neurite outgrowth.","PeriodicalId":49117,"journal":{"name":"Toxicology Mechanisms and Methods","volume":"32 1","pages":"635 - 643"},"PeriodicalIF":3.2,"publicationDate":"2016-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15376516.2016.1207735","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59851096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no study has investigated the possible toxic side effects of chitosan treatments, in particular when regarding the most important bioenergetic organelle, mitochondria. As such, we aimed to understand if supplementation of chitosan to the diet of normal and diabetic rats could compromise mitochondrial function on two of the major organs involved in diabetes, obesity, and metabolic regulation, the liver and skeletal muscle. We supplemented the drinking water of normal Wistar and diabetic Goto–Kakizaki rats with 0.5% chitosan for 6 weeks. We show here that, in terms of hepatic bioenergetics, chitosan was relatively inert and had no major side effects. However, regarding skeletal muscle bioenergetics, chitosan significantly affected various bioenergetic parameters. As such, we conclude that chitosan, at the tested doses, is relatively safe for treatment of diabetic situations.

Although protriptyline, a type of TCA, was used primarily in the clinical treatment of mood disorders in cancer patients, the effect of protriptyline on physiology in human osteosarcoma is unknown. This study examined the effect of protriptyline on cytosolic free Ca2+ concentrations ([Ca2+]i) and viability in MG63 human osteosarcoma cells. Protriptyline between 50 and 250 μM evoked [Ca2+]i rises concentration-dependently. Protriptyline induced influx of Mn2+, indirectly implicating Ca2+ influx. Protriptyline-evoked Ca2+ entry was inhibited by nifedipine by 20% but was not altered by econazole, SKF96365, GF109203X, and phorbol-12-myristate-13-acetate (PMA). In Ca2+-free medium, treatment with protriptyline inhibited the endoplasmic reticulum Ca2+ pump inhibitor thapsigargin-evoked [Ca2+]i rises. Conversely, treatment with thapsigargin inhibited 45% of protriptyline-evoked [Ca2+]i rises. Inhibition of phospholipase C (PLC) with U73122 failed to alter protriptyline-evoked [Ca2+]i rises. Protriptyline at 50–250 μM decreased cell viability, which was not reversed by pretreatment with the Ca2+ chelator 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid-acetoxymethyl ester (BAPTA/AM). Collectively, our data suggest that in MG63 cells, protriptyline induced [Ca2+]i rises by evoking Ca2+ release from the endoplasmic reticulum and other stores in a PLC-independent manner, and Ca2+ entry via a nifedipine-sensitive Ca2+ pathway. Protriptyline also caused Ca2+-independent cell death.","PeriodicalId":49117,"journal":{"name":"Toxicology Mechanisms and Methods","volume":"26 1","pages":"580 - 587"},"PeriodicalIF":3.2,"publicationDate":"2016-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15376516.2016.1216208","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59850813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
