Abstract
Cancer is one of the leading causes of death, and latest predictions indicate that cancer- related deaths will increase over the next few decades. Despite significant advances in conventional therapies, treatments remain far from ideal due to limitations such as lack of selectivity, non-specific distribution, and multidrug resistance. Current research is focusing on the development of several strategies to improve the efficiency of chemotherapeutic agents and, as a result, overcome the challenges associated with conventional therapies. In this regard, combined therapy with natural compounds and other therapeutic agents, such as chemotherapeutics or nucleic acids, has recently emerged as a new strategy for tackling the drawbacks of conventional therapies. Taking this strategy into consideration, the co-delivery of the above-mentioned agents in lipid-based nanocarriers provides some advantages by improving the potential of the therapeutic agents carried. In this review, we present an analysis of the synergistic anticancer outcomes resulting from the combination of natural compounds and chemotherapeutics or nucleic acids. We also emphasize the importance of these co-delivery strategies when reducing multidrug resistance and adverse toxic effects. Furthermore, the review delves into the challenges and opportunities surrounding the application of these co-delivery strategies towards tangible clinical translation for cancer treatment.

Sci Rep 2023; 13:5525.

Abstract
Despite the high antioxidant and penetration ability of pomegranate seed oil (PSO), the in vivo antitumor activity of PSO nano-emulsion has not been well investigated. Therefore, this study was undertaken to estimate the antitumor activity and safety of PSO nano-emulsion in mice bearing Ehrlich solid carcinoma cells. For tumor inoculation, about 2 × 106 viable Ehrlich tumor cells (200 µl) were implanted intramuscularly in the left thigh of hind leg. Once a solid tumor appears on the 10th day of transplantation; the mice were randomly divided into five groups (5 animals/group). Characterization of the PSO nano-emulsion using a Zeta sizer Malvern instrument and transmission electron microscope (TEM) revealed that the PSO nano-droplets were well dispersed with an average particle size of 8.95 nm and a spherical shape. Treatment with PSO nano-emulsions caused a significant reduction in the tumor size and weight, in a dose dependent manner, compared to tumor control group. Marked dose dependent elevations in the DNA damage level together with significant increases in the tumor suppressor p53, Bax and Caspase genes and reductions in the anti-apoptotic Bcl2 gene were also observed in the tumor tissue of mice given PSO nano-emulsions. Histological examination also revealed apoptosis and necrosis of tumor cells and tumor infiltration with inflammatory cells after PSO nano-emulsion treatment. However, high DNA damage was noticed in the liver and kidney tissues of mice given the highest dose of PSO nano-emulsion (400 mg/kg). Therefore, we concluded that PSO nano-emulsion exhibited a potent antitumor activity through induction of DNA breaks that triggers apoptosis of tumor cells but the highest dose caused genotoxicity to liver and kidney tissues, thus it is recommended to use doses lower than 400 mg/kg of PSO nano-emulsion as an alternative drugs for chemotherapy.

Abstract
AIMS In a previous work, a pure crystalline titanium dioxide nanoparticles (TiO2NPs) were synthesized by green synthesis technique using Aloe vera leaves extract as reducing agent. In this work, we are aiming to investigate the potential of the novel greenly synthesized TiO2NPs as a nano-drug delivery system for the anticancer drug, doxorubicin (Dox). MAIN METHODS The cytotoxicity of the synthesized TiO2NPs was tested on two cell lines; normal human skin fibroblasts (HSF) and breast adenocarcinoma cells (MCF-7). Then, Dox was loaded to both TiO2NPs (Dox- TiO2NPs) and liposomes (Dox-Lip). The loaded nanoparticles were characterized by TEM, FTIR, encapsulation efficiency, particle size and zeta potential measurement. Moreover, in vitro drug release was studied. Ehrlich tumor-bearing mice were used to study the anticancer activity of Dox- TiO2NPs, Dox-Lip, and aqueous Dox solution. Tumor volume, survival rate, and histopathological alterations were compared in all groups. KEY FINDINGS Dox was successfully loaded to both liposomes and TiO2NPs with an encapsulation efficiency of 77% and 65%, respectively. The particle size of Dox-TiO2NPs, and Dox-Lip was 14.53 nm, and 103 nm, respectively. The cumulative Dox released from TiO2NPs and liposomes after 4 h was 18 and 46%, respectively.Dox-Lip and Dox-TiO2NPs resulted in the highest degree of tumor growth inhibition with 100% and 83% of treated animals remained alive, respectively. SIGNIFICANCE The greenly synthesized TiO2NPs were proved to be as effective as liposomes in enhancing the anticancer activity of Dox.

Lipid-Based Nanovesicles for Simultaneous Intracellular Delivery of Hydrophobic, Hydrophilic, and Amphiphilic Species. Front Bioeng Biotechnol 2020; 8:690. [PMID: 32719782 PMCID: PMC7350901 DOI: 10.3389/fbioe.2020.00690] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 06/02/2020] [Indexed: 12/22/2022] Open
Abstract
Lipid nanovesicles (NVs) are the first nanoformulation that entered the clinical use in oncology for the treatment of solid tumors. They are indeed versatile systems which can be loaded with either hydrophobic or hydrophilic molecules, for both imaging and drug delivery, and with high biocompatibility, and limited immunogenicity. In the present work, NVs with a lipid composition resembling that of natural vesicles were prepared using the ultrasonication method. The NVs were successfully loaded with fluorophores molecules (DOP-F-DS and a fluorescent protein), inorganic nanoparticles (quantum dots and magnetic nanoparticles), and anti-cancer drugs (SN-38 and doxorubicin). The encapsulation of such different molecules showed the versatility of the developed systems. The size of the vesicles varied from 100 up to 300 nm depending on the type of loaded species, which were accommodated either into the lipid bilayer or into the aqueous core according to their hydrophobic or hydrophilic nature. Viability assays were performed on cellular models of breast cancer (MCF-7 and MDA-MB-231). Results showed that NVs with encapsulated both drugs simultaneously led to a significant reduction of the cellular activity (up to 22%) compared to the free drugs or to the NVs encapsulated with only one drug. Lipidomic analysis suggested that the mechanism of action of the drugs is the same, whether they are free or encapsulated, but administration of the drugs by means of nanovesicles is more efficient in inducing cellular damage, likely because of a quicker internalization and a sustained release. This study confirms the versatility and the potential of lipid NVs for cancer treatment, as well as the validity of the ultrasound preparation method for their preparation.

Abstract
Doxorubicin and Metformin HCL is a known chemotherapeutic combination that wipes out tumors and prevents their recurrence. However, limited site specificity confines its application. Here we report Doxorubicin and Metformin HCL-loaded guar gum micro-particles prepared by emulsification cum-solidification method. Developed micro-particles were characterized as spherical shape particles with smooth surface and micro size diameter. Encapsulation of drugs in combination was confirmed by their characteristic functional groups (FT-IR), change in phase transition temperature (DSC) and X-ray diffraction pattern (XRD). Particles were observed to be stable at 25 and 5°C. The in vitro Doxorubicin and Metformin HCL release study in simulated gastric (SGF), intestinal (SIF) and colonic fluid (SCF) confirms restricted release in SGF (9.3 and 9.6%, respectively, in 2 h) and SIF (10.8 and 14.7%, respectively, in the next 3 h) and highest release in SCF (about 68 and 73.3%, respectively) in colon. Developed micro-particles showed 78% recovery in tumor volume and considerable improvement in histological changes. X-ray images confirmed good target ability of micro-particles to colon. In conclusion, the specially designed, stable micro-particles are able to target drug combination to colon and improve efficacy by ensuring maximum drug release in colon as compared with Doxorubicin and Metformin HCL combination.

Abstract
BACKGROUND AND AIM Cancer stem cells (CSCs) are rare cell population present in the tumor bulk that are thought to be the reason for treatment failure following chemotherapy in terms of their intrinsic chemo-resistance. Our study aimed to develop an effective therapeutic strategy to target chemo-resistant cancer stem - like cells population in solid Ehrlich carcinoma (SEC) mice model using dendritic cells (DCs) loaded with enriched tumor cells lysate bearing CSC-like phenotype as a vaccine. MATERIALS AND METHODS Ehrlich carcinoma cell line was exposed to different concentrations of cisplatin, doxorubicin, or paclitaxel. Drug treatment that resulted in drug surviving cells with the highest expression of CSCs markers (CD44+/CD24-) was selected to obtain enriched cell cultures with resistant CSCs population. Dendritic cells were isolated from mice bone marrow, pulsed with enriched CSC lysate, analyzed and identified (CD11c, CD83 and CD86). SEC-bearing mice were treated with loaded or unloaded DCs either as single treatment or in combination with repeated low doses of cisplatin. IFN- γ serum level and p53gene expression in tumor tissues were determined by ELISA and real-time PCR, respectively. RESULTS AND CONCLUSION The results revealed that vaccination with CSC loaded DCs significantly reduced tumor size, prolonged survival rate, increased IFN-γ serum levels, and upregulated p53gene expression in SEC bearing mice. These findings were more evident and significant in the group co-treated with CSC-DC and cisplatin rather than other treated groups. This study opens the field for combining CSC-targeted immunotherapy with repeated low doses chemotherapy as an effective strategy to improve anticancer immune responses.

Abstract
Skin carcinogenesis is a common malignancy affecting humans worldwide, which could benefit from nutraceuticals as a solution to the drawbacks of conventional skin cancer treatment. (-)-epigallocatechin-3-gallate (EGCG) is a promising nutraceutical in this regard; however, it suffers chemical instability and low bioavailability resulting in inefficient delivery. Therefore, EGCG encapsulation in ultradeformable colloidal vesicular systems, namely: penetration enhancer-containing vesicles (PEVs), ethosomes and transethosomes (TEs) for topical administration has been attempted in this study to overcome the problems associated with the use of free EGCG. The prepared vesicles were characterized for their entrapment efficiency, TEM visualization, chemical compatibility, antioxidant properties, ex-vivo skin deposition, photodegradation and physical stability after storage. Most of the prepared vesicles exhibited reasonable skin deposition and preservation of the inherent antioxidant properties of EGCG with good physical stability. EGCG-loaded PEVs and TEs exhibited an inhibitory effect on epidermoid carcinoma cell line (A431) in addition to reduced tumor sizes in mice, confirmed with histopathological analysis and biochemical quantification of skin oxidative stress biomarkers; glutathione, superoxide dismutase and catalase, as well as lipid peroxidation. EGCG PEVs succeeded in offering an effective delivery system targeting skin cancer, which is worthy of further experimentation.

Abstract
Liposomes are lipid vesicles widely used as nanocarriers in targeted drug delivery systems for therapeutic and/or diagnostic purposes. A strategy to prolong the blood circulation time of the liposomes includes the addition of a hydrophilic polymer polyethylene glycol (PEG) moiety onto the surface of the vesicle. Several studies claim that liposome PEGylation by a single chain length or a combination of PEG with different chain lengths may alter the liposomes' pharmacokinetic properties. Therefore, the purpose of this study was to evaluate the influence of PEG on the biodistribution of pH-sensitive liposomes in a tumor-bearing animal model. Three liposomal formulations (PEGylated or not) were prepared and validated to have a similar mean diameter, monodisperse distribution, and neutral zeta potential. The pharmacokinetic properties of each liposome were evaluated in healthy animals, while the biodistribution and scintigraphic images were evaluated in tumor-bearing mice. High tumor-to-muscle ratios were not statistically different between the PEGylated and non-PEGylated liposomes. While PEGylation is a well-established strategy for increasing the blood circulation of nanostructures, in our study, the use of polymer coating did not result in a better in vivo profile. Further studies must be carried out to confirm the feasibility of the non-PEGylated pH-sensitive liposomes for tumor treatment.

Abstract
Cancer is a broad term used to describe a large number of diseases characterized by uncontrolled cell proliferation that leads to tumor production. Cancer is associated with mutations in genes controlling proliferation and apoptosis, oxidative stress, fatty acid synthase (FAS) expression, and other mechanisms. Currently, most antineoplastic drugs have severe adverse effects and new effective and safe drugs are needed. This study aims to investigate the possible anticancer activity of rutin and orlistat which are both safely used clinically in humans against two breast cancer models (in vivo EAC and in vitro MCF7) and the pancreatic cancer cell line (PANC-1). Our results have shown that both rutin and orlistat exerted an in vivo anticancer activity as evidenced by the decrease in tumor volume, CEA level, cholesterol content, FAS, and the exerted antioxidant action (reduced MDA level and increased GSH content) and through histopathological examination. In addition, both were cytotoxic to MCF-7 and Panc-1 cell lines by promoting apoptosis. In conclusion, the anticancer activity of rutin and orlistat makes them promising candidates for cancer treatment alone or in combination with other anticancer drugs specially that they are used clinically with an acceptable safety profile.

Abstract
PURPOSE The present study aimed to investigate the molecular mechanisms underlying the anticancer properties of ginger extract (GE) in mice bearing solid Ehrlich carcinoma (SEC) and to evaluate the use of GE in combination with doxorubicin (DOX) as a complementary therapy against SEC. METHODS SEC was induced in 60 female mice. Mice were divided into four equal groups: SEC, GE, DOX and GE + DOX. GE (100 mg/kg orally day after day) and DOX (4 mg/kg i.p. for 4 cycles every 5 days) were given to mice starting on day 12 of inoculation. On the 28th day, blood samples were collected, mice were scarified, tumor volume was measured, and tumor tissues were excised. RESULTS The anti-cancer effect of GE was mediated by activation of adenosine monophosphate protein kinase (AMPK) and down-regulation of cyclin D1 gene expression. GE also showed pro-apoptotic properties as evidenced by elevation of the P53 and suppression of nuclear factor-kappa B (NF-κB) content in tumor tissue. Co-administration of GE alongside DOX markedly increased survival rate, decreased tumor volume, and increased the level of phosphorylated AMPK (PAMPK) and improved related pathways compared to DOX group. In addition, the histopathological results demonstrated enhanced apoptosis and absence of multinucleated cells in tumor tissue of GE + DOX group. CONCLUSION AMPK pathway and cyclin D1 gene expression could be a molecular therapeutic target for the anticancer effect of GE in mice bearing SEC. Combining GE and DOX revealed a greater efficacy as anticancer therapeutic regimen.

Abstract
The aim of this study is to investigate the antitumor activity and possible molecular mechanism of Phenethyl isothiocyanate (PEITC) against Ehrlich ascites carcinoma in-vivo and in-vitro. In-vivo, ascetic fluid volume, body weight, serum malondialdehyde (MDA) level and total antioxidant capacity (TAC) were determined using Ehrlich ascites carcinoma (EAC) bearing mice. In-vitro, MTT assay was used. RT-PCR was used to investigate role of PEITC in apoptosis by analyzing the expression of Bax, caspase-9, and Bcl-2 genes. The effect of PEITC on caspase-9 enzyme activity was also tested. PEITC and/or Doxorubicin (Dox) treatment significantly suppressed EAC growth as compared to EAC/oil control mice. PEITC treatment showed a dose-dependent inhibition of EAC cells as indicated by MTT assay. We found that significant increase in MDA level and decrease in TAC caused by Dox treatment were significantly reduced by combination with PEITC treatment. Bax, caspase-9 genes' expression and caspase-9 enzymatic activity were significantly increased, while Bcl-2 gene expression was significantly decreased in PEITC treated mice. PEITC may act as a promising anticancer agent either alone or more effectively in combination with Dox through apoptotic cell death induction.

Abstract
Hybrid vesicles are considered as a bridge between natural nanosystems (NNSs) and artificial nanosystems (ANSs). NNSs are extracellular vesicles (EVs), membranous, bio-formed endogenously, which act as endogenous cargoes, and reflecting cellular dynamics. EVs have cellular tropism, permeate tight junctions, and are non-immunogenic. EVs are used as tools in the development of diagnostic and therapeutic agents. ANSs can induce biogenesis of hybrid vesicles as promising smart diagnostic agents, and innovative drug cargoes. EVs can encapsulate small molecules, macromolecules, and ANSs. The manipulation of EVs during biogenesis was suggested for engineering hybrid EVs. This review article highlights the role of ANSs in the biogenesis of NNSs, and introduces hybrid nanosystems research.

Abstract
ABSTRACT Electrochemotherapy is a local anticancer treatment in which non-permeant chemotherapeutic drugs are associated with electric pulses of well-established parameters. The electric pulses cause pores to open on the plasma membrane and facilitate drug transport, enhancing cytotoxicity and reducing side effects. Assessment of electrochemotherapy effects on Ehrlich solid tumor development in this work aims to evaluate in vivo usage of the electroporator device developed by the Department of Electrical Engineering of Engineering School of UFMG. Therefore, 40 Swiss mice were inoculated with Ehrlich tumor cells, and developed the tumor in solid form. After 21 days, mice were subjected to specific treatment protocols (control, bleomycin, electric pulses and electrochemotherapy); 17 days later they were euthanized and the tumors collected for histopathology analysis. Electrochemotherapy induced discrete weight loss and an inflammatory response in the tumor, which was not seen on the other treatment groups. Bleomycin alone induced necrosis. Both groups showed lower cellular proliferation rates. From this study, it was concluded that the animals tolerated electrochemotherapy treatment under anesthesia and the electroporator device developed by the Engineering School of UFMG was adequate when used in an electrochemotherapy protocol.

Abstract
Since the incidence of breast cancer increases dramatically all over the world, the search for effective treatment is an urgent need. Metformin has demonstrated anti-tumorigenic effect both in vivo and in vitro in different cancer types. This work was designed to examine on molecular level the mode of action of metformin in mice bearing solid Ehrlich carcinoma and to evaluate the use of metformin in conjunction with doxorubicin as a combined therapy against solid Ehrlich carcinoma. Ehrlich ascites carcinoma cells were inoculated in 60 female mice as a model of breast cancer. The mice were divided into four equal groups: Control tumor, metformin, doxorubicin, and co-treatment. Metformin (15 mg/kg) and doxorubicin (4 mg/kg) were given intraperitoneally (i.p.) for four cycles every 5 days starting on day 12 of inoculation. The anti-tumorigenic effect of metformin was mediated by enhancement of adenosine monophosphate protein kinase activity and elevation of P53 protein as well as the suppression of nuclear factor-kappa B, DNA contents, and cyclin D1 gene expression. Metformin and doxorubicin mono-treatments exhibited opposing action regarding cyclin D1 gene expression, phosphorylated adenosine monophosphate protein kinase, and nuclear factor-kappa B levels. Co-treatment markedly decreased tumor volume, increased survival rate, and improved other parameters compared to doxorubicin group. In parallel, the histopathological findings demonstrated enhanced apoptosis and absence of necrosis in tumor tissue of co-treatment group. Metformin proved chemotherapeutic effect which could be mediated by the activation of adenosine monophosphate protein kinase and related pathways. Combining metformin and doxorubicin, which exhibited different mechanisms of action, produced greater efficacy as anticancer therapeutic regimen.

Abstract
The aim of this work was to use the quality-by-design (QbD) approach in the development of long-circulating liposomes co-loaded with curcumin (CUR) and doxorubicin (DOX) and to evaluate the cytotoxic potential of these liposomes in vitro using C26 murine colon carcinoma cell line. Based on a risk assessment, six parameters, namely the phospholipid, CUR and DOX concentrations, the phospholipid:cholesterol molar ratio, the temperature during the evaporation and hydration steps and the pH of the phosphate buffer, were identified as potential risk factors for the quality of the final product. The influence of these variables on the critical quality attributes of the co-loaded liposomal CUR and DOX was investigated: particle size, zeta potential, drug loading and entrapment efficiency. For this, a 26−2 factorial design was employed to establish a proper regression model and to generate the contour plots for the responses. The obtained data served to establish the design space for which different combinations of variables yielded liposomes with characteristics within predefined specifications. The validation of the model was carried out by preparing two liposomal formulations corresponding to the robust set point from within the design space and one outside the design space and calculating the percentage bias between the predicted and actual experimental results. The in vitro antiproliferative test showed that at higher CUR concentrations, the liposomes co-encapsulating CUR and DOX had a greater cytotoxic effect than DOX-loaded liposomes. Overall, this study showed that QbD is a useful instrument for controlling and optimizing the manufacturing process of liposomes co-loaded with CUR and DOX and that this nanoparticulate system possesses a great potential for use in colon cancer therapy.

Abstract
Nanovesicles (NVs) represent a novel transporter for cell signals to modify functions of target cells. Therefore, NVs play many roles in both physiological and pathological processes. This report highlights biogenesis, composition and biological roles of erythrocytes derived nanovesicles (EDNVs). Furthermore, we address utilization of EDNVs as novel drug delivery cargo as well as therapeutic target. EDNVs are lipid bilayer vesicles rich in phospholipids, proteins, lipid raft, and hemoglobin. In vivo EDNVs biogenesis is triggered by an increase of intracellular calcium levels, ATP depletion and under effect of oxidative stress conditions. However, in vitro production of EDNVs can be achieved via hypotonic treatment and extrusion of erythrocyte. NVs can be used as biomarkers for diagnosis, monitoring of therapy and drug delivery system. Many therapeutic agents are suggested to decrease NVs biogenesis.

Abstract
BACKGROUND The use of liposomes as drug delivery systems is the most promising technique for targeting drug especially for anticancer therapy. METHODS In this study sterically stabilized liposomes was prepared from DPPC/Cholesterol/PEG-PE encapsulated doxorubicin. The effect of lyophilization on liposomal stability and hence expiration date were studied. Moreover, the effect of diode laser on the drug released from liposomesin vitro and in vivo in mice carrying implanted solid tumor were also studied. RESULTS The results indicated that lyophilization of the prepared liposomes encapsulating doxorubicin led to marked stability when stored at 5 °C and it is possible to use the re-hydrated lyophilized liposomes within 12 days post reconstitution. Moreover, the use of low energy diode laser for targeting anticancer drug to the tumor cells is a promising method in cancer therapy. CONCLUSION We can conclude that lyophilization of the liposomes encapsulating doxorubicin lead to marked stability for the liposomes when stored at 5 °C. Moreover, the use of low energy diode laser for targeting anticancer drug to the tumor cells through the use of photosensitive sterically stabilized liposomes loaded with doxorubicin is a promising method. It proved to be applicable and successful for treatment of Ehrlich solid tumors implanted in mice and eliminated toxic side effects of doxorubicin.
