Mesenchymal stem/stromal cell (MSC)-based therapy has become an attractive and advanced scientific research area in the context of cancer therapy. This interest is closely linked to the MSC-marked tropism for tumors, suggesting them as a rational and effective vehicle for drug delivery for both hematological and solid malignancies. Nonetheless, the therapeutic application of the MSCs in human tumors is still controversial because of the induction of several signaling pathways largely contributing to tumor progression and metastasis. In spite of some evidence supporting that MSCs may sustain cancer pathogenesis, increasing proofs have indicated the suppressive influences of MSCs on tumor cells. During the last years, a myriad of preclinical and some clinical studies have been carried out or are ongoing to address the safety and efficacy of the MSC-based delivery of therapeutic agents in diverse types of malignancies. A large number of studies have focused on the MSC application as delivery vehicles for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), chemotherapeutic drug such as gemcitabine (GCB), paclitaxel (PTX), and doxorubicin (DOX), prodrugs such as 5-fluorocytosine (5-FC) and ganciclovir (GCV), and immune cell-activating cytokines along with oncolytic virus. In the current review, we evaluate the latest findings rendering the potential of MSCs to be employed as potent gene/drug delivery vehicle for inducing tumor regression with a special focus on the in vivo reports performed during the last two decades.

A biodegradable drug delivery system (DDS) is one the most promising therapeutic strategies for cancer therapy. Here, we propose a unique concept of light activation of black phosphorus (BP) at hydrogel nanostructures for cancer therapy. A photosensitizer converts light into heat that softens and melts drug-loaded hydrogel-based nanostructures. Drug release rates can be accurately controlled by light intensity, exposure duration, BP concentration, and hydrogel composition. Owing to sufficiently deep penetration of near-infrared (NIR) light through tissues, our BP-based system shows high therapeutic efficacy for treatment of s.c. cancers. Importantly, our drug delivery system is completely harmless and degradable in vivo. Together, our work proposes a unique concept for precision cancer therapy by external light excitation to release cancer drugs. If these findings are successfully translated into the clinic, millions of patients with cancer will benefit from our work.

Cavitation-facilitated microbubble-mediated focused ultrasound therapy is a promising method of drug delivery across the blood–brain barrier (BBB) for treating many neurological disorders. Unlike ultrasound thermal therapies, during which magnetic resonance thermometry can serve as a reliable treatment control modality, real-time control of modulated BBB disruption with undetectable vascular damage remains a challenge. Here a closed-loop cavitation controlling paradigm that sustains stable cavitation while suppressing inertial cavitation behavior was designed and validated using a dual-transducer system operating at the clinically relevant ultrasound frequency of 274.3 kHz. Tests in the normal brain and in the F98 glioma model in vivo demonstrated that this controller enables reliable and damage-free delivery of a predetermined amount of the chemotherapeutic drug (liposomal doxorubicin) into the brain. The maximum concentration level of delivered doxorubicin exceeded levels previously shown (using uncontrolled sonication) to induce tumor regression and improve survival in rat glioma. These results confirmed the ability of the controller to modulate the drug delivery dosage within a therapeutically effective range, while improving safety control. It can be readily implemented clinically and potentially applied to other cavitation-enhanced ultrasound therapies.

The NR4A1–NR4A3 (Nur77, Nurr1, and Nor-1) subfamily of nuclear receptors is a group of immediate early genes induced by a pleiotropy of stimuli including peptide hormones, growth factors, cytokines, inflammatory, and physiological stimuli, and cellular stress. NR4A receptors function as potent sensors of changes in the cellular microenvironment to control physiological and pathological processes through genomic and non-genomic actions. NR4A receptors control metabolism and cardiovascular and neurological functions and mediate immune cell homeostasis in inflammation and cancer. This receptor subfamily is increasingly recognized as an important molecular connection between chronic inflammation, altered immune cell responses, and cancer development. In this review, we examine how transcriptome analysis identified NR4A1/NR4A2 receptors as transcriptional regulators in mesenchymal stromal cell (MSC) migration, cell cycle progression, and cytokine production to control local immune responses. In chronic inflammatory conditions, such as rheumatoid arthritis, NR4A receptors have been shown to modify the activity of MSC and fibroblast-like stromal cells to regulate synovial tissue hyperplasia, pathological angiogenesis, and cartilage turnover in vivo. Additionally, as NR4A1 has been observed as a major transcriptional regulator in tumor–stromal communication controlling tumorigenesis, we discuss how advances in the pharmacological control of these receptors lead to important new mechanistic insights into understanding the role of the tumor microenvironment in health and disease.

Oncolytic viruses (OLVs) including measles and mumps viruses (MeV and MuV) have a potential to serve as a therapeutic option for cancers. We have previously shown that the combination of MeV and MuV synergistically kills various human haematological cancer cells. This study aims to investigate the anti-tumor activity of MeV, MuV and MeV-MuV combination (MM) against human solid malignancies in vitro and in vivo. The results showed that MeV, MuV and MM combination targeted and effectively killed various cancer cell lines of human solid malignancies but not normal cells. Notably, MM combination demonstrated a greater anti-tumor effect and prolonged survival in a human prostate cancer (PC3) xenograft tumour model compared to MeV and MuV. MeV, MuV and MM combination significantly induced the expression of immunogenic cell death (ICD) markers and enhanced spleen-infiltrating immune cells such as macrophages, natural killer and dendritic cells. Our study demonstrated that MM combination is a promising option for treatment of human solid malignancies and suggested that MM could induce immunogenic cell death of malignant cells and activate immunity against cancers.

Aim: A preclinical safety assessment of a novel nanoemulsion drug-delivery system, initially developed to improve the posology of efavirenz (EFV), was conducted with a specific focus on possible immunological and hematological complications. Materials & methods: Assessment of common acute toxicities, such as complement activation and cytokine secretion, was performed using validated assays known to have good correlation with in vivo end points. Results & conclusion: Compared with a standard aqueous solution of EFV, the EFV nanoemulsion showed no significant effect on immune cell function or phenotype. Prolongation of activated partial thromboplastin time was observed for EFV-loaded nanoemulsions (88% at 4 μg/ml) as well as unloaded nanoemulsions (52%) highlighting the potential for drug-free anticoagulant activity and warranting further investigation of the mechanism and utility of these materials.

Background: Cancer is defined as an abnormal/uncontrolled cell growth that shows rapid cell division. This disease is annually recognized in more than ten million people. Nanomaterials can be used as new strategies for cancer therapy. Nanostructured devices have developed for drug delivery and controlled release and created novel anticancer chemotherapies. Nanomaterials were taken into consideration because of their new properties, containing a large specific surface area and high reactivity. Copper oxide nanoparticles (CuONPs) have potential applications in many fields like heterogeneous catalysis, antibacterial, anticancer, antioxidant, antifungal, antiviral, imaging agents, and drug delivery agents in biomedicine. CuONPs display different physical properties, such as hightemperature superconductivity, electron correlation effects, and spin dynamics. NPs can be synthesized using different methods like physical, chemical, and biological methods. Methods: Copper oxide nanoparticles (CuONPs) have been suggested for its broad usage in biomedical applications. In this review, we tried to exhibit the results of significant anticancer activity of green synthesized CuONPs and their characterization by different analytical techniques such as UV-Vis, FT-IR, XRD, EDAX, DLS, SEM, and TEM. Results: The green method for the synthesis of CuO nanoparticles as eco-friendly, cost-effective, and facile method is the more effective method. Synthesized CuONPs from this method have an appropriate size and shape. The Green synthesized CuONPs exhibited high potential against several breast cancer (AMJ-13, MCF-7, and HBL-100 cell lines), cervical cancer (HeLa), colon cancer (HCT-116), gastric cancer (human adenocarcinoma AGS cell line), lung cancer (A549), leukemia cancer, and other cancers with the main toxicity approach of increasing ROS production. Conclusion: The present review confirms the importance of green synthesized CuO nanoparticles in medical science especially cancer therapy that exhibited high activity against different cancer in both in vitro and in vivo. The main toxicity approach of CuONPs is increasing the production of reactive oxygen species (ROS). It needs to perform more studies about in vivo cancer therapy and following clinical trial testing in the future. We believe that green synthesized CuO nanoparticles can be used for the improvement of different diseases.
