Background: Doxorubicin, as a strong anti-cancer agent for clinical treatment of various cancer types along with other drugs, is widely utilized. Due to the physiology of the human body and cancerous tissues, the applicability of doxorubicin is still limited and the targeted treatment of the different types of cancers is considered. Also, the side effects of the conventional forms of chemotherapy medicines, damaging and stressing the normal cells are considerable. Objective: This study introduces a novel and effective system for the targeted release of doxorubicin by successfully fabricating the green magnetic graphene oxide, chitosan, allium sativum, and quercus nanocomposite. Methods: The in vitro release of doxorubicin loaded on the nanocomposite was evaluated and investigated at pH 7.4 and 6.5, respectively. The drug diffusivity in the plasma environment was assessed for a more accurate analysis of the drug diffusion process. The nanocomposite loaded drug release mechanism and kinetics, as well as cytotoxicity assay was investigated. Results: The efficiency of the drug encapsulation was significantly enhanced using natural extract ingredients and consequently, the efficacy of the targeted treatment of cancerous tissues was improved. The developed nanocomposite provided a controlled release of doxorubicin in similar acidic conditions of the normal and cancerous cells and affirming that the fabricated system is thoroughly pH-dependent. Conclusion: The cytotoxicity assay confirmed that the fabricated nanocomposite at a high growth rate of cancerous cells has an anticancer property and acts as a toxic agent against tumor cells, suggesting that in conjunction with doxorubicin, it can be highly improved for killing cancerous cells.

The rainbow trout hepatoma cell line, RTH-149, was evaluated for use as a bioindicator cell type in the neutral red cytotoxicity assay. The cells were exposed for six days to various polycyclic aromatic hydrocarbons, including chemicals that are direct-acting toxicants and chemicals that require enzymatic biotransformation to cytotoxic metabolites. Whereas benzo[a]pyrene was only slightly cytotoxic, its metabolites — (±)trans-7,8-diol-benzo[a]pyrene and 3-hydroxy-benzo[a]pyrene — were highly cytotoxic. 7,12-Dimethylbenz[a]anthracene was cytotoxic, but cytotoxicity did not occur with benzo[a]anthracene, benzo[b]fluoranthene and benzo[k]fluoranthene. This cell line appears to lack sufficient xenobiotic metabolising capacity to biotransform many of these polycyclic aromatic hydrocarbons to activated cytotoxic metabolites.

AbstractCytotoxicity assays are essential for the testing and development of novel immunotherapies for the treatment of cancer. We recently described a novel cytotoxicity assay, termed the Matador assay, which was based on marine luciferases and their engineered derivatives. In this study, we describe the development of a new cytotoxicity assay termed ‘Matador-Glo assay’ which takes advantage of a thermostable variant of Click Beetle Luciferase (Luc146-1H2). Matador-Glo assay utilizes Luc146-1H2 and D-luciferin as the luciferase-substrate pair for luminescence detection. The assay involves ectopic over-expression of Luc146-1H2 in the cytosol of target cells of interest. Upon damage to the membrane integrity, the Luc146-1H2 is either released from the dead and dying cells or its activity is preferentially measured in dead and dying cells. We demonstrate that this assay is simple, fast, specific, sensitive, cost-efficient, and not labor-intensive. We further demonstrate that the Matador-Glo assay can be combined with the marine luciferase-based Matador assay to develop a dual luciferase assay for cell death detection. Finally, we demonstrate that the Luc146-1H2 expressing target cells can also be used for in vivo bioluminescence imaging applications.
