Nanovaccines: Immunogenic tumor antigens, targeted delivery, and combination therapy to enhance cancer immunotherapy.

Nanovaccines have been designed to overcome the limitations associated with conventional vaccines. Effective delivery methods such as engineered carriers or smart nanoparticles (NPs) are critical requisites for inducing self-tolerance and optimizing vaccine immunogenicity with minimum side effects. NPs can be used as adjuvants, immunogens, or nanocarriers to develop nanovaccines for efficient antigen delivery. Multiloaded nanovaccines carrying multiple tumor antigens along with immunostimulants can effectively increase immunity against tumor cells. They can be biologically engineered to boost interactions with dendritic cells and to allow a gradual and constant antigen release. Modifying NPs surface properties, using high-density lipoprotein-mimicking nanodiscs, and developing nano-based artificial antigen-presenting cells such as dendritic cell-derived-exosomes are amongst the new developed technologies to enhance antigen-presentation and immune reactions against tumor cells. The present review provides an overview on the different perspectives, improvements, and barriers of successful clinical application of current cancer therapeutic and vaccination options. The immunomodulatory effects of different types of nanovaccines and the nanoparticles incorporated into their structure are described. The advantages of using nanovaccines to prevent and treat common illnesses such as AIDS, malaria, cancer and tuberculosis are discussed. Further, potential paths to develop optimal cancer vaccines are described. Given the immunosuppressive characteristics of both cancer cells and the tumor microenvironment, applying immunomodulators and immune checkpoint inhibitors in combination with other conventional anticancer therapies are necessary to boost the effectiveness of the immune response.

Enhanced delivery of doxorubicin for breast cancer treatment using pH-sensitive starch/PVA/g-C3N4 hydrogel.

This study introduces a starch/PVA/g-C3N4 nanocarrier hydrogel for pH-sensitive DOX delivery in breast cancer. DOX was loaded into the nanocarrier with 44.75 % loading efficiency and 88 % Entrapment Efficiency. The release of DOX from the starch/PVA/g-C3N4 hydrogel was pH-sensitive: DOX was released faster in the acidic environment pertinent to cancer tumors (with a pH level of 5.4) than in the surrounding regular tissue environment carrying a more neutral environment (pH 7.4). The release kinetics analysis, encompassing zero-order, first-order, Higuchi, and Korsmeyer-Peppas models, revealed significant fitting with the Higuchi model at both pH 5.4 (R2 = 0.99, K = 9.89) and pH 7.4 (R2 = 0.99, K = 5.70) levels. Finally, we found that hydrogel was less damaging to healthy cells and more specific to apoptotic cells than the drug's free form. The starch/PVA/g-C3N4 hydrogel had low toxicity for both normal cells and breast cancer cells, whereas DOX loaded into the starch/PVA/g-C3N4 hydrogel had higher toxicity for cancer cells than the DOX-only control samples, and led to specific high apoptosis for cancer cells. The study suggests that DOX can be loaded into a starch/PVA/g-C3N4 hydrogel to improve the specificity of the drug's release in cancer tumors or in vitro breast cancer cells.

Nanotherapeutic approaches for delivery of long non-coding RNAs: an updated review with emphasis on cancer.

The long noncoding RNAs (lncRNAs) comprise a wide range of RNA species whose length exceeds 200 nucleotides, which regulate the expression of genes and cellular functions in a wide range of organisms. Several diseases, including malignancy, have been associated with lncRNA dysregulation. Due to their functions in cancer development and progression, lncRNAs have emerged as promising biomarkers and therapeutic targets in cancer diagnosis and treatment. Several studies have investigated the anti-cancer properties of lncRNAs; however, only a few lncRNAs have been found to exhibit tumor suppressor properties. Furthermore, their length and poor stability make them difficult to synthesize. Thus, to overcome the instability of lncRNAs, poor specificity, and their off-target effects, researchers have constructed nanocarriers that encapsulate lncRNAs. Recently, translational medicine research has focused on delivering lncRNAs into tumor cells, including cancer cells, through nano-drug delivery systems in vivo. The developed nanocarriers can protect, target, and release lncRNAs under controlled conditions without appreciable adverse effects. To deliver lncRNAs to cancer cells, various nanocarriers, such as exosomes, microbubbles, polymer nanoparticles, 1,2-dioleyl-3-trimethylammoniumpropane chloride nanocarriers, and virus-like particles, have been successfully developed. Despite this, every nanocarrier has its own advantages and disadvantages when it comes to delivering nucleic acids effectively and safely. This article examines the current status of nanocarriers for lncRNA delivery in cancer therapy, focusing on their potential to enhance cancer treatment.

Regulation of the P53 tumor suppressor gene and the Mcl-2 oncogene expression by an active herbal component delivered through a smart thermo-pH-sensitive PLGA carrier to improve Osteosarcoma treatment.

Osteosarcoma (OS), a lethal malignancy, has witnessed an escalating incidence rate. Contemporary therapeutic strategies for this cancer have proven to be inadequate, primarily due to their extensive side effects and the lack of specificity in targeting the molecular pathways implicated in this disease. Consequently, this project is aimed to manufacture and characterize Poly (Lactic-co-glycolic acid) embodying curcumin, a phytocompound devoid of adverse effects which not only exerts an anti-neoplastic influence but also significantly modulates the genetic pathways associated with this malignancy. In this investigation, multiple formulations of PLGA-Cur were synthesized, and the choice of optimal formula was made considering the efficiency of nanoparticle encapsulation and the drug dispersion rate from synthesized PLGA. The selected formulation's physical and chemical attributes, such as its dimension, polydispersity index of the formulation, surface electrical charge, physical-spatial structure, and stability, were examined using methods, including Dynamic light scattering (DLS), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and spectrophotometry. Subsequently, the absence of interaction between the drug and the system was assessed using Fourier Transform Infrared Spectroscopy (FT-IR), and cellular uptake was evaluated using fluorescence microscopy. The smart system's responsiveness to environmental stimuli was determined using the dialysis bag method and its anti-tumor properties were investigated on the SAOS-2 cell line. Finally, to evaluate the system's genetic impact on bone cancer, the molecular quantification of the P53 tumor suppressor gene and the oncogene MCL-2 was analyzed using real-time PCR and their protein expression levels were also examined. The PLGAs synthesized in this study exhibited an encapsulation rate of 91.5 ± 1.16% and a maximum release rate of 71 ± 1%, which were responsive to various stimuli. The size of the PLGAs was 12.5 ± 321.2 nm, with an electric charge of -38.9 ± 2.6 mV and a PDI of 0.107, indicating suitable morphology and stability. Furthermore, both the system and the drug retained their natural properties after inoculation. The system was readily absorbed by cancer cells and effectively exerted its anti-cancer properties. Notably, the system had a significant impact on the mentioned genes' expression. The produced nanosystem, possessing optimal physicochemical properties, has the potential to enhance the anti-cancer efficacy of curcumin. This is achieved by altering molecular and genetic pathways within cancer cells, thereby positioning it as a viable adjunctive treatment modality and also synthesizing of this herbal base drug system consider as a completely novel method for cancer therapy that can efficiently modulate genetical pathways involved.

QbD-Based Fabrication of Biomimetic Hydroxyapatite Embedded Gelatin Nanoparticles for Localized Drug Delivery against Deteriorated Arthritic Joint Architecture.

Biomaterials such as nanohydroxyapatite and gelatin are widely explored to improve damaged joint architecture associated with rheumatoid arthritis (RA). Besides joint damage, RA is associated with inflammation of joints and cartilage, which potentiates the need for both bone nucleation and therapeutic intervention. For such purpose, a modified nanoprecipitation method is used herein to fabricate tofacitinib (Tofa)-loaded nanohydroxyapatite (nHA) embedded gelatin (GLT) nanoparticles (NPs) (Tofa-nHA-GLT NPs). The quality by design (QbD) approach is chosen to assess the key parameters that determine the efficiency of the NPs, and are further optimized via Box-Behnken design of experiment. The particle size, polydispersity, zeta potential, and encapsulation efficiency (EE) of the prepared NPs are found to be 269 nm, 0.18, -20.5 mV, and 90.7%, respectively. Furthermore, the NPs have improved stability, skin permeability, and a sustained drug release pattern at pH 6.5 (arthritic joint pH). Moreover, rhodamine-B loaded nHA-GLT NPs demonstrates considerably higher cellular uptake by the murine-derived macrophages than free rhodamine-B solution. In vitro, cell-based experiments confirm the good cell biocompatibility with insignificant toxicity. Thus, QbD-based approach has successfully led to the development of Tofa-nHA-GLT NPs with the potential to target inflamed arthritic joint.

Development of chitosan based ß-carotene mucoadhesive formulation for skin cancer treatment.

Mucopermeating nanoformulations can enhance mucosal penetration of poorly soluble drugs at their target site. In this work, thiolated chitosan (TCS)-lithocholic acid (LA) nanomicelles loaded with ß-carotene, a safe phytochemical with anticancer properties, were designed to improve the pharmaceutical and pharmacological drug profile. The TCS-LA nanomicelles were characterized by FTIR to confirm the presence of the thiol group that favors skin adhesion, and to corroborate the conjugation of hydrophobic LA with hydrophilic CS to form an amphiphilic polymer derivative. Their crystalline nature and thermal behavior were investigated by XRD and DSC analyses, respectively. According to DLS and TEM, their average size was <300 nm, and their surface charge was +27.0 mV. ß-carotene entrapment and loading efficiencies were 64 % and 58 %, respectively. In vitro mucoadhesion and ex vivo mucopenetration analyses further corroborated the potential of the nanoformulation to deliver the drug in a sustained manner under conditions mimicking cancer micro-environment. Anticancer studies in mice demonstrated that the loaded nanomicelles delayed skin cancer growth, as revealed by both morphological and biochemical parameters. Based on the results obtained herein, it can be concluded that drug-loaded TCS-LA is a novel, stable, effective and safe mucoadhesive formulation of ß-carotene for the potential treatment of skin cancer.

Novel chitosan/γ-alumina/carbon quantum dot hydrogel nanocarrier for targeted drug delivery.

Curcumin (CUR) is among the most natural and effective antitumor drugs for cancer treatment. These drugs have low solubility and short half-lives that reduce their effectiveness in drug release systems. Herein, a hydrogel nanocarrier containing chitosan (CS), alumina (γ-Al2O3), and carbon quantum dots (CQDs) was prepared by the water-in-oil-in-water (W/O/W) double nanoemulsion method. DLS revealed a nanocarrier size of 227 nm, with a zeta potential of -37.8 mV, which corroborates its stability. FE-SEM showed its quasi-spherical shape, FT-IR and XRD confirmed the presence of all the components in the nanocomposite and gave information about the intermolecular interactions between them and the crystalline nature of the nanocarrier, respectively. The drug loading (48 %) and entrapment efficiency (86 %) were higher than those reported previously for other CUR nanocarriers. The drug release profile revealed a controlled and stable release, and a pH-sensitive behavior, with faster CUR release in an acid environment. The breast cancer cell line was examined by cytotoxicity and cell apoptosis analyses. The results showed that the slow release over time and the programmed cell death were due to interactions between CUR and the nanocarrier. Considering the results obtained herein, CS/γAl2O3/CQDs/CUR can be considered as a promising new nanosystem for tumor treatment.
