Abstract
Nanotechnology, an emerging and promising therapeutic tool, may improve the effectiveness of phototherapy (PT) in antitumor therapy because of the development of nanomaterials (NMs) with light-absorbing properties. The tumor-targeted PTs, such as photothermal therapy (PTT) and photodynamic therapy (PDT), transform light energy into heat and produce reactive oxygen species (ROS) that accumulate at the tumor site. The increase in ROS levels induces oxidative stress (OS) during carcinogenesis and disease development. Because of the localized surface plasmon resonance (LSPR) feature of copper (Cu), a vital trace element in the human body, Cu-based NMs can exhibit good near-infrared (NIR) absorption and excellent photothermal properties. In the tumor microenvironment (TME), Cu2+ combines with H2O2 to produce O2 that is reduced to Cu1+ by glutathione (GSH), causing a Fenton-like reaction that reduces tumor hypoxia and simultaneously generates ROS to eliminate tumor cells in conjunction with PTT/PDT. Compared with other therapeutic modalities, PTT/PDT can precisely target tumor location to kill tumor cells. Moreover, multiple treatment modalities can be combined with PTT/PDT to treat a tumor using Cu-based NMs. Herein, we reviewed and briefly summarized the mechanisms of actions of tumor-targeted PTT/PDT and the role of Cu, generated from Cu-based NMs, in PTs. Furthermore, we described the Cu-based NMs used in PTT/PDT applications.

Abstract
Plant derived polyphenolic compounds are considered critical components of human nutrition and have shown chemotherapeutic effects against a number of malignancies. Several studies have confirmed the ability of polyphenols to induce apoptosis and regression of tumours in animal models. However, the mechanism through which polyphenols modulate their malignant cell selective anticancer effects has not been clearly established. While it is believed that the antioxidant properties of these molecules may contribute to lowering the risk of cancer induction by causing oxidative damage to DNA, it could not be held responsible for chemotherapeutic properties and apoptosis induction. It is a well known fact that cellular copper increases within the malignant cell and in serum of patients harboring malignancies. This phenomenon is independent of the cellular origin of malignancies. Based on our own observations and those of others; over the last 30 years our laboratory has shown that cellular copper reacts with plant derived polyphenolic compounds, by a Fenton like reaction, which generates reactive oxygen species and leads to genomic DNA damage. This damage then causes an apoptosis like cell death of malignant cells, while sparing normal cells. This communication reviews our work in this area and lays the basis for understanding how plant derived polyphenols can behave as prooxidants (and not antioxidants) within the microenvironment of a malignancy (elevated copper levels) and gives rationale for their preferential cytotoxicity towards malignant cells.

Abstract
β-resorcylic acid (BR) is a phytochemical which is widely used in the food industry as a flavouring agent and preservative. It has also been found to exhibit antibacterial action against several types of food-borne bacteria. DNA is the main molecular target for many small molecules of therapeutic importance. Hence, the interest is rapidly growing among the researchers to elucidate the interaction between small molecules and DNA. Thus, paving the way to design novel DNA-specific drugs. In this study, an attempt was made to examine the mechanism of binding of BR with calf thymus DNA (ctDNA) with the help of various experiments based on spectroscopy and in silico studies. The spectroscopic studies like UV absorption and fluorescence affirmed the complex formation between BR and ctDNA. The observed binding constant was in the order of 103 M-1 which is indicative of the groove binding mechanism. These findings were further verified by dye-displacement assay, potassium iodide quenching, urea denaturation assay, the study of the effect of ssDNA, circular dichroism and DNA thermal denaturing studies. Different temperature-based fluorescence and isothermal titration calorimetry (ITC) experiments were employed to evaluate thermodynamic parameters. The analysis of thermodynamic parameters supports the enthalpically driven, exothermic and spontaneous nature of the reaction between BR and ctDNA. The forces involved in the binding process were mainly found to be hydrogen bonding, van der Waals and hydrophobic interactions. The results obtained from the molecular docking and molecular dynamics (MD) simulation were consistent with the in vitro experiments, which support the groove binding mode of BR with ctDNA.

Abstract
Adverse health effects have been observed in nearby residents due to exposure to petrochemical-derived chemicals. The objective of this study was to examine associations of soluble metals with lung and liver toxicity in fine particulate matter (PM2.5) in the vicinity of a petrochemical complex. PM2.5 was collected in the vicinity of a petrochemical complex of Mailiao Township (Yunlin County, Taiwan) to investigate lung and liver toxicity in BALB/c mice. The PM2.5 concentration was 30.2 ± 11.2 μg/m3, and the PM2.5 was clustered in major local emissions (19.1 μg/m3) and minor local emissions (14.1 μg/m3) using a k-means clustering model. The PM2.5 (50 and 150 μg/kg) and PM2.5-equivalent soluble nickel (Ni), vanadium (V), and lead (Pb) concentrations were intratracheally instilled into BALB/c mice. PM2.5 and V significantly decreased the tidal volume after exposure (p < 0.05). The peak expiratory flow (PEF) and peak inspiratory flow (PIF)/PEF ratio were significantly altered by 150 μg/kg V (p < 0.05). V and Pb significantly increased total protein and lactate dehydrogenase (LDH) levels in bronchoalveolar lavage fluid (BALF) (p < 0.05). Interleukin (IL)-6 in BALF significantly increased after exposure to Pb (p < 0.05) accompanied by lung inflammatory infiltration. PM2.5 and Pb significantly increased levels of 8-isoprostane (p < 0.05). The level of caspase-3 activity significantly increased after exposure to Pb (p < 0.05). LDH in the liver was significantly increased by PM2.5 (p < 0.05). 8-Isoprostane in the liver was significantly increased by PM2.5 and Pb (p < 0.05). IL-6 in the liver was significantly increased by PM2.5, Ni, V, and Pb after exposure (p < 0.05), accompanied by liver inflammatory infiltration. Our results demonstrated that V in PM2.5 was associated with an increase in 8-isoprostane for all emissions and major local petrochemical emissions. In conclusion, V contributes to in vivo liver toxicity induced by PM2.5 in the vicinity of a petrochemical complex.

Abstract
Copper homeostasis is generally investigated focusing on a single component of the metallostasis network. Here we address several of the factors controlling the metallostasis for neuroblastoma cells (SH-SY5Y) upon treatment with 2,9-dimethyl-1,10-phenanthroline-5,6-dione (phendione) and 2,9-dimethyl-1,10-phenanthroline (cuproindione). These compounds bind and transport copper inside cells, exert their cytotoxic activity through the induction of oxidative stress, causing apoptosis and alteration of the cellular redox and copper homeostasis network. The intracellular pathway ensured by copper transporters (Ctr1, ATP7A), chaperones (CCS, ATOX, COX 17, Sco1, Sco2), small molecules (GSH) and transcription factors (p53) is scrutinised.

Abstract
Cancer cells have higher demand of iron and copper ions for growth, disturbing the metal's homeostasis can inhibit proliferation of cancer cell. Dithiocarbamates possessing excellent metal chelating ability and antitumor activity are considered as candidates in chelation therapy, however, their antitumor molecular mechanisms remain to be elucidated. In the present study, a dithiocarbamate derivative, di-2-pyridylhydrazone dithiocarbamate s-acetic acid (DpdtaA) was prepared to address the issue whether the molecular mechanism behind biological behavior showed by dithiocarbamate was p53 mediated. The proliferation inhibition assay showed that DpdtaA exhibited excellent antiproliferative effect for hepatocellular carcinoma (IC50= 3.0±0.4 µM for HepG2, 6.1±0.6 µM for Bel-7402 cell). However, in the presence of copper ion, the antiproliferative activity of DpdtaA significantly attenuated (~3-fold for HepG2) due to formation of copper chelate. The ROS assay revealed that the antiproliferative activity of DpdtaA correlated with ROS generation. Western blotting demonstrated that DpdtaA could upregulate p53 via down-regulating the Mdm2, accordingly leading to changes of bcl family proteins, indicating that a p53-dependent intrinsic apoptosis was partly involved. Simulation from molecular docking hinted that DpdtaA could disrupt interaction between p53 and Mdm2, indicating the disruption might also contribute to the upregulation of p53. The alternations in lysosome membrane permeability and acidic vacuoles as well as LC3-II upregulation indicated that autophagy was involved. The copper addition led to significantly attenuate biological activity of DpdtaA, with few dithiocarbamates, but the mechanism in apoptosis induction was not altered except for weaker ability.

Abstract
Troxerutin (TXER) a rutin derivative is known for its anticancer effect against hepatocellular carcinoma (HCC). As part of large study, recently we have shown TXER interact with genetic material and its anti-mutagenic property. In the present study we have explored its possible mode of action in HCC. Since TXER alone did not show significant anticancer effect on Huh-7 cells, in vitro biochemical assays were performed for determining anticancer efficacy of TXER + metal complex using transition metals such as Cu, Zn, and Fe. The anticancer efficacy of TXER + Cu on Huh-7 cells were evaluated using MTT assay, DCFDA, JC-1 staining, comet assay, cell cycle analysis, immunocytochemistry, and Western blotting. Non-toxic nature of TXER was analyzed on primary rat hepatocytes. The in vivo efficacy of TXER was tested in N-nitrosodiethylamine initiated and γ-benzene hexachloride and partial hepatectomy promoted rat liver cancer. Liver markers, transition metal levels, histopathological examination, and expression levels of GST-P, 8-OHdG and Ki-67 were studied to assess the in vivo anticancer effect of TXER. We observed that TXER + Cu induced extensive cellular death on Huh-7 cells through generating free radicals and did not possess any toxic effect on normal hepatocytes. The in vivo studies revealed that TXER possess significant anti-cancer effect as assessed through improved liver markers and suppressed GST-P, 8-OHdG, and Ki-67 expression. TXER treatment reduced the hepatic Cu level in cancer bearing animals. Current study brings the putative mechanism involved in anti-cancer effect of TXER, further it will help to formulate phytoconstituents coupled anti-cancer drug for effective treatment of HCC.

Abstract
Tubulin targeting agents have received considerable interest as a potential tumor-selective vascular disrupting agents, which represent another avenue for cancer growing therapeutic opportunities. Hence, the present study was conducted to investigate the anti-tumor activity of Combretastatin A-4 phosphate (CA4-P) and vincristine against hepatocellular carcinoma in rats, by individual administration and in combination. In vitro study was conducted using human hepatocellular carcinoma cell lines, showed that CA4-P and vincristine have a potent cell cytotoxic and tubulin inhibitory effect. In addition, a remarkable synergistic effect was observed by the simultaneous application of both drugs. Whereas in vivo study was conducted using model of rat liver cancer initiated with DENA and promoted by CCl4, showed that CA4-P and vincristine were significantly decreased liver relative weight, number of hepatic nodules and there relative volumes, tubulin content of the hepatic tissue, GSH and AFP. On the other hand, co-administration of both drugs exhibited significant further decrements in these parameters. Whereas a marked increase in MDA, carbonyl content and TNF-α inside hepatic tissue were observed in the treated groups and these increments were more prominent by co-administration of both drugs. In conclusion CA4-P showed a potential anti-cancer activity against hepatocellular carcinoma and this effect was greatly enhanced by co-administration with vincristine. Additionally, our new findings provided an important evidence that the anticancer activity of drugs with a narrow therapeutic window such as vincristine can be greatly improved by its co-administration with CA4-P providing more enhanced activity with less side effects.

Abstract
The use of chelators for cancer treatment has been an alternative option. Dithiocarbamates have recently attracted considerable attention owning to their diverse biological activities; thus, the preparation of new dithiocarbamate derivatives with improved antitumor activity and selectivity as well as probing the underlying molecular mechanism are required. In this study, di-2-pyridylhydrazone dithiocarbamate S-propionic acid (DpdtpA) and its copper complex were prepared and characterized, and its antiproliferative activity was evaluated. The proliferation inhibition assay showed that DpdtpA exhibited excellent antiproliferative effect in hepatocellular carcinoma (IC50 = 1.3 ± 0.3 μM for HepG2, and 2.5 ± 0.6 μM for Bel-7402). However, in the presence of copper ion, the antiproliferative activity of DpdtpA was dramatically attenuated (20–30 fold) owing to the formation of copper chelate. A preliminarily mechanistic study revealed that reactive oxygen species (ROS) generation mediated the antiproliferative activity of DpdtpA, and accordingly induced apoptosis, DNA cleavage, and autophagy. Surprisingly, the cytotoxicity of DpdtpA copper complex (DpdtpA–Cu) was also involved in ROS generation; however, a paradoxical relation between cellular ROS level and cytotoxicity was observed. Further investigation indicated that DpdtpA could induce cell cycle arrest at the S phase; however, DpdtpA–Cu lacked this effect, which explained the difference in their antiproliferative activity.

Abstract
Ferulic acid (FA) is a plant polyphenol showing diverse therapeutic effects against cancer, diabetes, cardiovascular and neurodegenerative diseases. FA is a known antioxidant at lower concentrations, however at higher concentrations or in the presence of metal ions such as copper, it may act as a pro-oxidant. It has been reported that copper levels are significantly raised in different malignancies. Cancer cells are under increased oxidative stress as compared to normal cells. Certain therapeutic substances like polyphenols can further increase this oxidative stress and kill cancer cells without affecting the proliferation of normal cells. Through various in vitro experiments we have shown that the pro-oxidant properties of FA are enhanced in the presence of copper. Comet assay demonstrated the ability of FA to cause oxidative DNA breakage in human peripheral lymphocytes which was ameliorated by specific copper-chelating agent such as neocuproine and scavengers of ROS. This suggested the mobilization of endogenous copper in ROS generation and consequent DNA damage. These results were further validated through cytotoxicity experiments involving different cell lines. Thus, we conclude that such a pro-oxidant mechanism involving endogenous copper better explains the anticancer activities of FA. This would be an alternate non-enzymatic, and copper-mediated pathway for the cytotoxic activities of FA where it can selectively target cancer cells with elevated levels of copper and ROS.
