Abstract
Cisplatin, a potent chemotherapeutic agent, is marred by severe nephrotoxicity that is governed by mechanisms involving oxidative stress, inflammation, and apoptosis pathways. The transcription factor Nrf2, pivotal in cellular defense against oxidative stress and inflammation, is the master regulator of the antioxidant response, upregulating antioxidants and cytoprotective genes under oxidative stress. This review discusses the mechanisms underlying chemotherapy-induced kidney injury, focusing on the role of Nrf2 in cancer therapy and its redox regulation in cisplatin-induced kidney injury. We also explore Nrf2's signaling pathways, post-translational modifications, and its involvement in autophagy, as well as examine redox-based strategies for modulating Nrf2 in cisplatin-induced kidney injury while considering the limitations and potential off-target effects of Nrf2 modulation. Understanding the redox regulation of Nrf2 in cisplatin-induced kidney injury holds significant promise for developing novel therapeutic interventions. This knowledge could provide valuable insights into potential strategies for mitigating the nephrotoxicity associated with cisplatin, ultimately enhancing the safety and efficacy of cancer treatment.

Abstract
Nanosuspensions have emerged as a promising strategy for the efficient delivery of hydrophobic drugs because of their versatile features and unique advantages. Techniques such as media milling and high-pressure homogenization have been used commercially for producing nanosuspensions. Recently, the engineering of nanosuspensions employing emulsions and microemulsions as templates has been addressed in the literature. The unique features of nanosuspensions have enabled their use in various dosage forms, including specialized delivery systems such as mucoadhesive hydrogels. Rapid strides have been made in the delivery of nanosuspensions by parenteral, peroral, ocular and pulmonary routes. Currently, efforts are being directed to extending their applications in site-specific drug delivery.

Abstract
This article represents the first comprehensive assessment of hormetic effects of chemotherapeutic agents. Hormetic dose-response relationships were reported for a wide range of chemotherapeutics, including antibiotics, antiviral, and antitumor agents as well as substances that affect hair growth, prostate function, cognitive performance, and numerous other endpoints. Particular attention was given to assessing the quantitative features of the dose response, the underlying mechanistic features of the biphasic nature of the dose response, and the clinical implications of hormetic responses. Recognition of the hormetic-like biphasic nature of the dose response is expected to have an important impact on the design of experiments to assess chemotherapeutics and how such agents may be employed more successfully in clinical applications.

Abstract
Poorly-water-soluble compounds are difficult to develop as drug products using conventional formulation techniques and are frequently abandoned early in discovery. The use of media milling technology to formulate poorly-water-soluble drugs as nanocrystalline particles offers the opportunity to address many of the deficiencies associated with this class of molecules. NanoCrystal Technology is an attrition process wherein large micron size drug crystals are media milled in a water-based stabilizer solution. The process generates physically stable dispersions consisting of nanometer-sized drug crystals. Nanocrystalline particles are a suitable delivery system for all commonly used routes of administration, i.e. oral, injectable (IV, SC, and IM) and topical applications. In addition, aqueous dispersions of nanoparticles can be post-processed into tablets, capsules, fast-melts and lyophilized for sterile product applications. The technology has been successfully incorporated into all phases of the drug development cycle from identification of new chemical entities to refurbishing marketed products for improving their performance and value.

Abstract
Doxorubicin-loaded PACA nanoparticles have been shown to be more efficient than free drug in mice bearing hepatic metastasis of the M5076 tumour. Due to the high phagocytic activity of Küpffer cells in the liver, it may be that these cells played a role of drug reservoir after nanoparticle phagocytosis. Therefore, the objective of this study was to assess the role of macrophages in mediating the cytotoxicity of doxorubicin-loaded nanoparticles on M5076 cells. The growth inhibition of tumour cells was evaluated in two ways: firstly, the cells were incubated in a coculture system consisting of special wells with two compartments separated by a porous membrane. M5076 cells were seeded into the lower compartment and the macrophages J774.A1 were introduced into the upper part. The macrophages were activated or not by IFN-gamma. The drug preparations were added only in the macrophage insert. Secondly, growth inhibition was also assessed in the conventional way, i.e. in direct contact with the tumour cells to serve as a reference. After direct contact, free doxorubicin (Dox) and doxorubicin-loaded nanoparticles (NP-Dox) had the same efficacy against M5076 cell growth. The coculture experiments led to a 5-fold increase in the IC(50) for both Dox and NP-Dox. The activation of macrophages by IFN-gamma in coculture significantly decreased the IC(50) values. In conclusion, after phagocytosis of doxorubicin-loaded nanoparticles, J774.A1 cells were able to release active drug, allowing it to exert its cytotoxicity against M5076 cells. Drug efficacy was potentiated by the activation of macrophages releasing cytotoxic factors such as NO, which resulted in increased tumour cell death. Thereby, the coculture system permitted us to investigate the macrophage-mediated cytotoxicity of colloidal carriers loaded with an anticancer drug, which is of great interest when further i.v. administration is envisaged.

Abstract
PURPOSE Investigation of the ability of doxorubicin-loaded nanoparticles (NP/Dox) to overcome multidrug resistance (MDR) when they have first been taken up by macrophages. METHODS The growth inhibition of P388 sensitive (P388) and resistant (P388/ADR) tumor cells was evaluated in a coculture system consisting of wells with two compartments. The tumor cells were seeded into the lower compartment, the macrophages were introduced into the upper part in which the drug preparations were also added. RESULTS Doxorubicin exerted lower cytotoxicity on tumor cells in coculture compared with direct contact. In P388/ADR, NP/Dox cytotoxicity was far higher than that of free doxorubicin (Dox). Three different formulations of cyclosporin A (either free (CyA), loaded to nanoparticles (NP/CyA) or in a combined formulation with doxorubicin (NP/Dox-CyA)), were added to modulate doxorubicin efficacy. The addition of cyclosporin A to Dox increased drug cytotoxicity. Both CyA added to NP/Dox and NP/Dox-CyA were able to bypass drug resistance. CONCLUSIONS Despite the barrier role of macrophages, NP/Dox remained far more cytotoxic than Dox against P388/ADR. Both NP/Dox + CyA and NP/Dox-CyA allowed to overcome MDR, but the last one should present greater advantage in vivo by confining both drugs in the same compartment, hence reducing the adverse effects.

Abstract
Kupffer cells, which are part of the reticuloendothelial system, play an important role in clearing pathogenic substances, including tumor cells, from the liver. The role of Kupffer cells in tumor development is very important as Kupffer cells can be manipulated to a tumoricidal state with biological response modifiers to kill tumor cells and thus to decrease tumor burden and extend survival time. To gain additional information on the role of Kupffer cells and their interaction with tumor cells in hepatic metastases, we studied an established experimental hematogenous metastatic model (Friend erythroleukemia) in mouse livers by light and electron microscopy. Highly activated Kupffer cells were observed in close contact with tumor cells in sinusoids and also in tumor forming foci within the hepatic parenchyma. The Kupffer cells were activated by the presence of the hematogenous tumor cells and were able to lyse and phagocytose them. However, some tumor cells evaded the Kupffer cells as metastases still occurred. Kupffer cells and other macrophages were found to leave the sinusoids and migrate to sites of potential tumor development where they interacted with tumor cells and intimately wrapped their processes around fat storing cells. It is possible that these macrophages which cross biological barriers could be used to deliver drug-loaded microparticles (liposomes and microcapsules) to tumors.
