Inorganic Selenium

The effects of organic and inorganic forms of selenium (Se) on human cells have been extensively studied for nutritional concentrations; however, to date, little is known about the potential toxicity at supranutritional levels. In the present study we determined the effects of sodium selenite (SSe) and selenomethionine (SeMet) on cell growth and intracellular structures in lung cancer cells exposed at Se concentrations between 0 and 3 mM. Our results showed that SSe affected cell growth more rapidly than SeMet (24 h and 48 h, resp.). After 24 h of cells exposure to 0.5, 1.5, and 3 mM SSe, cell growth was reduced by 10, 50, and 60%, as compared to controls. After 48 h, nuclear fragmentation was evident in cells exposed to SSe, suggesting an induction to cell death. In contrast, SeMet did not affect cell proliferation, and the cells were phenotypically similar to controls. Microtubules and microfilaments structures were also affected by both Se compounds, again SSe being more toxic than SeMet. To our knowledge, this is the first report on the differential effects of organic and inorganic Se in supranutritional levels in lung cancer cells.

Aim: Present work was undertaken to fabricate iron oxide nanoparticles (IONPs) using a green approach for increased therapeutic efficacy. Materials & methods: Two types of IONPs were synthesized, one without any coating (IONPUC) and other coated with Phyllanthus emblica (Amla) fruit extract (IONPA). Both the IONPs were characterized using different techniques and therapeutic efficacy was evaluated in A549 human lung cancer cell line. Results: IONPA were smaller in size with better dispersibility compared with IONPUC. They induced increased reactive oxygen species production, higher DNA damage and apoptosis, which resulted in increased toxicity to cancer cells in comparison to IONPUC. Conclusion: Higher uptake of IONPA and active components coating the surface, may be responsible for the increased therapeutic efficacy in cancer cells.

Chemotherapy is a type of cancer treatment in which the lack of selective cytotoxicity often leads to intolerable side effects. Today, the use of medicinal plants is essential in treating cancer due to their fewer side effects. Lagenaria siceraria Standl is critical for cytotoxicity studies due to its polyphenolic, cucurbitacins, pectin, flavonoids, and saponin compounds. In this study, the cytotoxic effects of plant fruit extract were investigated on lung cancer cell lines. To this end, the hydroalcoholic extract of the plant fruit was initially prepared by the percolation method. Then, the effects of solutions containing samples with different concentrations (5000, 500, 1000, 100, 100, 250, 10, 1, 0.1μg.ml-1) were investigated by MTT assay on lung cancer cell line (A549). Cisplatin was considered as a positive control. Statistical calculations were carried out using Prism V.3 software to compare IC50, and the data were analyzed by analysis of variance (ANOVA) and t-test. The results indicated that the IC50 level of cisplatin anti-cancer drug, as a common drug in the market, is significantly lower than Lagenaria siceraria extract. However, the extract of this plant revealed a significant growth inhibitory effect on lung cancer cells. The results also showed that Lagenaria siceraria extract is an effective cytotoxic compound on lung cancer cells. More extensive studies are needed to find effective plant extracts compounds to find and design new and effective cancer treatment drugs.

Reversal Effect

This research is aimed on reversing multidrug resistance (MDR) of chemotherapy in lung cancer. According to our previous research, chemotherapeutic drugs resistance in lung cancer is mainly due to high expression of multidrug resistance-associated protein (MRP) gene and activation of caspases. The effect of stephania tetrandra-containing Chinese herbal formula, namely Supplement Energy and Nourish Lung (SENL), is effective in enhancing efficacy and reducing toxicity of chemotherapy in lung cancer. However, the underlying mechnism is largely unknown. To understand whether and how SENL herbs function on multidrug-resistance lung cancer cells, we treated a multidrug resistance lung cancer cell line, SW1573/2R120 with SENL herbs alone or together with a chemotherapeutic drug, Adriamycin (ADM). We observed that SENL herbs had a significant synergistic effect with ADM in inhibiting the growth of SW1573/2R120 cells. SENL alone and particularly together with ADM could significantly increase cell apoptotic death via mitochondria- and caspase-dependent pathway. Furthermore, we showed that SENL herbs could reverse drug resistance of lung cancer cells by decreasing MRP expression and increasing accumulation of intracellular ADM, which in turn increase the sensitivity of cancer cells to ADM. Taken together, the mechanism underlying reversal effect of drug resistance by SENL treatment was reported here and further systematical investigation on SENL herbs may lead to solve drug resistance in lung cancer chemotherapy.

e19095 Backgrounds: Recent studies reported that zoledronic acid, a biphosphonate with proposed apoptotic activity, could cause a direct antitumor effect. Our prior study [J Clin Oncol 26: 2008 (May 20 suppl; abstr 19116)] reported that Zoledronic acid combined with Cisplatin shows significantly synergistic antitumor effects on lung cancer cell line A549 and subcutaneous implanted tumor on nude mice. Investigate whether zoledronic acid, augmented the cytotoxicity of cisplatin and/or paclitaxel in A549 lung cancer cell line. Methods: This cell line was subjected to different concentrations of the above chemotherapeutic agents and zoledronic acid. Cytotoxicity was assessed by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrasodium bromide) assay. Flow cytometry was used to examine cell cycle,cell apoptosis rate. Results: Zoledronic acid in in 50 micromolar (mM) concentration augmented the cytotoxicity by cisplatin in 10μmol/L and paclitaxel in 5μmol/L. Zoledronic acid could inhibit the proliferation of lung cancer cells in vitro,which was associated with arresting of G1 phase and inducing apoptosis by a time-dependent and dose-dependentmanner. The apoptosis rate of cell increased after zoledronic acid combined with cisplatin and/or paclitaxel. Conclusions: Zoledronic acid can induce apoptosis and block cell cycle of lung cancer cells. Zoledronic acid has also shown synergistic antitumor effects when combined with cisplatin and/or paclitaxel. The clinical potential of this finding should be further studied.

Cancer is a dynamic disease involving constant changes. With these changes, cancer cells become heterogeneous, resulting in varying sensitivity to chemotherapy. The heterogeneity of cancer cells plays a key role in chemotherapy resistance and cancer recurrence. Therefore, for effective treatment, cancer cells need to be analyzed at the single-cell level by monitoring various proteins and investigating their heterogeneity. We propose a microfluidic chip for a single-cell proteomics assay that is capable of analyzing complex cellular signaling systems to reveal the heterogeneity of cancer cells. The single-cell assay chip comprises (i) microchambers (n = 1376) for manipulating single cancer cells, (ii) micropumps for rapid single-cell lysis, and (iii) barcode immunosensors for detecting nine different secretory and intracellular proteins to reveal the correlation among cancer-related proteins. Using this chip, the single-cell proteomics of a lung cancer cell line, which may be easily masked in bulk analysis, were evaluated. By comparing changes in the level of protein secretion and heterogeneity in response to combinations of four anti-cancer drugs, this study suggests a new method for selecting the best combination of anti-cancer drugs. Subsequent preclinical and clinical trials should enable this platform to become applicable for patient-customized therapies.

Purpose: Nuclear ubiquitous casein and cyclin-dependent kinases substrate (NUCKS) overexpression has been reported in various types of cancers. The purpose of this study is to clarify the role of NUCKS, underlying the involvement of non-small-cell lung cancer, in the progression of lung cancer. Methods: The small interfering ribonucleic acid (siRNA) of NUCKS was transfected into a lung cancer cell line (NCI-H460, A549, NCI-H1299 and NCI-H1975). Functional experiments (MTT assay, Annexin V-FITC/PI double staining assay, colony formation assay, wound healing assay and Transwell assay) were performed to measure the effects of NUCKS on lung cancer cell viability, migration, invasion and apoptosis. Results: NUCKS was found to be up-regulated in lung cancer cells. Knockdown of NUCKS significantly altered lung cancer cell apoptosis, proliferation colony formation, invasion and migration. Moreover, knockdown of NUCKS attenuated the activation of the PI3K/AKT pathway in lung cancer cells. Conclusion: NUCKS was overexpressed in lung cancer cells and played an important role in lung cancer by increasing cell growth through the PI3K/AKT signalling pathway. This in vitro study suggested NUCKS should be evaluated in a clinical setting as a novel biomarker and potential therapeutic target for lung cancer.

It is a good therapeutic method that add exogenous ROS to trigger oxidative stress causing death of cancer cells. In the present study, we investigated the inhibitory effects of 3,4,5-trihydroxybenzoic acid (TBA), a polyhydroxyphenolic compound, on high metastatic human lung cancer cell line (95-D) based on inducing reactive oxygen species (ROS). The experiments in vitro showed that 95-D cell viability was inhibited by various amounts of TBA and death was induced in a dose-dependent manner. The possible mechanism was that TBA can induce cell death by decreasing mitochondrial membrane potential (MMP; ΔΨm) and increasing hydrogen peroxide (H2O2) level. These results imply that TBA efficiently induces death in 95-D lung cancer cells and that TBA exerts cytotoxicity on cancer cells by its pro-oxidative activity.
