This investigation was designed to assess the cytotoxic and apoptotic effects of selenium nanoparticles. It explored the cytotoxic effects of selenium nanoparticles in MCF-7 and HepG2 cell lines. The morphology of selenium nanoparticles was analyzed by transmission electron microscopy (TEM) to verify their size and crystalline properties. The selenium nanoparticles were almost spherical and cubic in shape and in size (∼20 nm). Selenium nanoparticles were tested for their cytotoxic activity in MCF-7 and HepG2 cell lines using MTT and NRU assays. We found relative differences in the vulnerability of both cell lines in their response to selenium nanoparticle-induced cytotoxicity. Specifically, MCF-7 cells exhibited greater vulnerability to exposure to selenium nanoparticles than HepG2 cells. Selenium nanoparticles exposure also induced higher mRNA levels of apoptosis related genes and caspase-3 enzyme activity. Overall, the present study provided the evidence of cytotoxicity induced by SeNPs via apoptotic gene expression in human cell lines. These results warrant further investigation into more precise mechanism(s) of selenium nanoparticles-induced cell death in in vivo model systems.

Background: Silver nanoparticles play a significant role in bioavailability and refining the compatibility of natural drugs in the treatment of various chronic diseases including different types of cancer. Objective: Green synthesis of silver nanocomposites of Nigella sativa seeds extract to evaluate the anticancer effects against hepatocellular carcinoma using HepG2 cell lines. Methods: The AgNCs were developed by treating aqueous extract of N. sativa seeds treated with silver nitrate (1mM) solution and were used to test its efficacy against hepatocellular carcinoma using HepG2 cell lines. Results and Discussion: The Surface Plasmon Resonance (SPR) of prepared AgNCs showed a peak at 432 nm via UV spectroscopy. The selected N. sativa AgNCs were characterized for polydispersity, surface charge and size and the results showed 0.215±0.093 polydispersity index (PDI), zeta potential 18.8±0.372 mV and size range 10-20 nm, respectively. The Fourier transform infrared spectroscopy (FTIR) also showed various peak of functional groups that are possibly involved in the reduction of silver ion and synthesized the N. sativa silver nanocomposites, respectively. N. sativa AgNCs showed 89.954% drug release while in the case of extract release, it was only 33.821% in 24 hrs. Further, in vitro studies of N. sativa AgNCs against hepatocellular carcinoma showed good cytotoxic effect p<0.05 with 7.16 µg/ml IC50 value. Conclusion: Thus, the present results revealed that green synthesis of N. sativa AgNCs can be an alternative tool for clinical application in cancer therapy; however, there is a need to find the mechanism and role of AgNCs inside the individual.

A new material of copper(II) complex (complex 1) with taurine Schiff base has been synthesized and characterized by elemental analysis, ESI-MS and IR spectra. 1 was tested against HepG2 cell lines with IC50 values of 12.89 μM. With the concentrations of 1 increasing, the population of apoptosis was 1.28% for 0 μM, 24.4% for 10 μM and 47.9% for 20μM, and the population of G2 phase was 19.2% for 0 μM, 34.4% for 10 μM and 42.9% for 20μM, respectively. 1 showed significant cytotoxic activity against HepG2 cell lines.

247 Background: In case of non resectable HCC, radioembolization and sorafenib (S) are therapeutic options respectively for intermediate and advanced stages. In some other cancers, there is an increase of efficacy when external beam radiotherapy is done concomitantly with systemic chemotherapy or targeted therapies. So we wondered if there could be a synergistic or an additive activity when S is combined with a radionuclide. Methods: Hepatoma cell lines N1S1 (murine HCC), HepG2 (human hepatoblastoma) and HepaRG (human HCC) were treated with increasing concentrations of rhenium-188 (188Re) or S. On each cell line, we have studied the cellular toxicities of S and 188Re using Tetrazolium dye test, extra-cellular medium LDH level and morphologic analysis. This was done for different dosage of S and 188Re. We measured the lethal concentration killing 25% of cells (LC25) with the results of the Tetrazolium dye test. Secondly, we looked for synergy or additivity on cellular toxicity of these two compounds according to cell lines by combined treatment. Synergy or additivity was estimated with the combination index (CI) method (synergy if CI lower than 1, additivity if CI = 1, antagonism if CI upper to 1) based on the Tetrazolium dye test’s results. Results: Monotherapy dose-dependent toxicities were observed for all three cell lines with 188Re and for the N1S1 and HepG2 cell lines only with S. Combined treatment with 188Re and S showed synergy on HepaRG and N1S1 cell lines and additivity on the HepG2 cell line. Conclusions: The additive, and even synergistic, interest of a combined treatment with 188Re and S is demonstrated in vitro (for the first time to our knowledge) on hepatoma cell lines. This results, in particular for the HepaRG cell line (human HCC), could be explained by the down-regulation of the hepatic drug transporters which are responsible for the Sorafenib efflux in case of simultaneous DNA damages due to a radionuclide exposition. This promising approach now needs to be confirmed in vivo. [Table: see text]
