[PMID: 38675155 PMCID: PMC11054685 DOI: 10.3390/pharmaceutics16040494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/26/2023] [Accepted: 01/08/2024] [Indexed: 04/28/2024] Open
Abstract
Currently, there is still a lack of effective carriers with minimal side effects to deliver therapeutic miRNA. Thus, it is crucial to optimize novel drug delivery systems. MiR-375 has proven superior therapeutic potency in Hepatocellular carcinoma (HCC). The purpose of this study was to fabricate 2 novel and smart nano-carriers for the transportation efficiency of miR-375 in HCC cells and enhance its anti-tumor effects. We established the miR-375 construct through the pEGP- miR expression vector. Two nano-carriers of solid/liquid lipids and chitosan (CS) were strategically selected, prepared by high-speed homogenization, and optimized by varying nano-formulation factors. Thus, the two best nano-formulations were designated as F1 (0.5% CS) and F2 (1.5% CS) and were evaluated for miR-375 conjugation efficiency by gel electrophoresis and nanodrop assessment. Then, physio-chemical characteristics and stability tests for the miR-375 nano-plexes were all studied. Next, its efficiencies as replacement therapy in HepG2 cells have been assessed by fluorescence microscopy, flow cytometry, and cytotoxicity assay. The obtained data showed that two cationic nanostructured solid/liquid lipid carriers (NSLCs); F1 and F2 typically had the best physio-chemical parameters and long-term stability. Moreover, both F1 and F2 could form nano-plexes with the anionic miR-375 construct at weight ratios 250/1 and 50/1 via electrostatic interactions. In addition, these nano-plexes exhibited physical stability after three months and protected miR-375 from degradation in the presence of 50% fetal bovine serum (FBS). Furthermore, both nano-plexes could simultaneously deliver miR-375 into HepG2 cells and they ensure miR re-expression even in the presence of 50% FBS compared to free miR-375 (p-value < 0.001). Moreover, both F1 and F2 alone significantly exhibited minimal cytotoxicity in treated cells. In contrast, the nano-plexes significantly inhibited cell growth compared to free miR-375 or doxorubicin (DOX), respectively. More importantly, F2/miR-375 nano-plex exhibited more anti-proliferative activity in treated cells although its IC50 value was 55 times lower than DOX (p-value < 0.001). Collectively, our findings clearly emphasized the multifunctionality of the two CS-coated NSLCs in terms of their enhanced biocompatibility, biostability, conjugation, and transfection efficiency of therapeutic miR-375. Therefore, the NSLCs/miR-375 nano-plexes could serve as a novel and promising therapeutic strategy for HCC.

pH-Responsive PEGylated Niosomal Nanoparticles as an Active-Targeting Cyclophosphamide Delivery System for Gastric Cancer Therapy. Molecules 2022; 27:molecules27175418. [PMID: 36080186 PMCID: PMC9457647 DOI: 10.3390/molecules27175418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 08/13/2022] [Accepted: 08/18/2022] [Indexed: 11/17/2022] Open
Abstract
A PEGylated niosomal formulation of cyclophosphamide (Nio-Cyclo-PEG) was prepared using a central composite design and characterized in terms of drug loading, size distribution, and average size. The stability of formulations was also studied at different conditions. In vitro cytotoxicity of drug delivery formulations was assessed on gastric cancer cells using MTT assay. The mechanism of cytotoxicity was studied at the transcriptional level by real-time PCR on Caspase3, Caspase9, CyclinD, CyclinE, MMP-2, and MMP-9 genes, while apoptosis was investigated with flow cytometry. The anti-metastatic property was evaluated using the scratch method. Propidium iodide staining was used to study the cell cycle. The results indicated that the as-designed nanocarrier exhibited a controlled drug release pattern with improved nanoparticle stability. It was found that the living cancer cells treated with Nio-Cyclo-PEG showed a significant decrease in number when compared with the niosomal carrier without PEG (Nio-Cyclo) and free drug (Cyclo). Moreover, the drug-loaded nanocarrier induced planned death (apoptosis) in the cancer cells through the regulation of Caspase3, Caspase9, CyclinD, CyclinE, MMP-9, and MMP-2 gene expression, indicating that the Nio-Cyclo-PEG formulation could significantly inhibit the cell cycle at the sub G1 phase as well as prevent the migration of cancer cells. In conclusion, Nio-Cyclo-PEG as developed in this study could serve as an active-targeting drug delivery nanocarriers for gastric cancer therapy with high efficacy and minimal side effects on healthy tissues/cells.

Quercetin encapsulated in Folic Acid-Modified Liposomes is therapeutic against osteosarcoma by non-Covalent binding to the JH2 Domain of JAK2 Via the JAK2-STAT3-PDL1. Pharmacol Res 2022; 182:106287.

Abstract
Osteosarcoma (OS) is a malignant solid tumor prone to lung metastasis that occurs in adolescents aged 15-19 years. Neoadjuvant chemotherapy and surgical treatment aimed at curing OS have gained limited progress over the last 30 years. Exploring new effective second-line therapies for OS patients is a serious challenge for researchers. Quercetin, a multiple biologically active polyphenolic flavonoid, has been used in tumor therapy. However, the exact mechanism of quercetin is still unknown, which limits the application of quercetin. In the current study, we found that quercetin could inhibit JAK2 through the JH2 domain in a non-covalent manner, resulting in the inhibition of OS proliferation and immune escape via the JAK2-STAT3-PD-L1 signaling axis. More importantly, to overcome the shortcomings of quercetin, including low water solubility and low oral availability, we encapsulated it with folic acid-modified liposomes. The transportation of quercetin by folic acid-modified liposomes may provide a feasible strategy to cure OS.

Abstract
BACKGROUND Cancer development is associated with abnormal, uncontrolled cell growth and causes significant economic and social burdens to society. The global statistics of different cancers have been increasing because of the aging population, and the increasing prevalence of risk factors such as stress condition, overweight, changing reproductive patterns, and smoking. The prognosis of cancer treatment is high, if diagnosed in the early stage. Late-stage diagnosis, however, is still a big challenge for the clinician. The usual treatment scheme involves chemotherapy and surgery followed by radiotherapy. SCOPE OF REVIEW Chemotherapy is the most widely used therapeutic approach against cancer. However, it suffers from the major limitation of poor delivery of anticancer therapeutics to specific cancer-targeted tissues/cells. MAJOR CONCLUSIONS Nanomedicines, particularly nanostructured lipid carriers (NLCs) can improve the efficacy of encapsulated payload either through an active or passive targeting approach against different cancers. The targeted nanomedicine can be helpful in transporting drug carriers to the specifically tumor-targeted tissue/cells while sparing abstaining from the healthy tissue/cells. The active targeting utilizes the binding of a specific cancer ligand to the surface of the NLCs, which improves the therapeutic efficacy and safety of the cancer therapeutics. GENERAL SIGNIFICANCE This review shed light on the utilization of NLCs system for targeted therapy in different cancers. Furthermore, modification of NLCs as cancer theranostics is a recent advancement that is also discussed in the manuscript with a review of contemporary research carried out in this field.

Abstract
AIM This study was aimed to develop Eudragit S100-coated, pH-awakened microbeads (MBs) encapsulating folic acid (FA)-modified tristearin solid lipid nanoparticles (SLNs) loaded with oxaliplatin (OP). Afterward, these formulations were evaluated (in vitro and in vivo) for their potential against colorectal cancer (CRC). METHODS The SLNs were synthesised by employing the solvent diffusion technique and then they were entrapped in the MBs. The prepared uncoupled and coupled SLNs (SLN-OP and FA-SLN-OP, respectively) were examined for in vitro cytotoxicity effect against COLO-205. Gamma-scintigraphy study was used for determining biodistribution (in vivo) of drug in different organs through MBs. RESULTS Outcomes for FA-SLN-OP revealed more cytotoxicity (50% inhibitory concentration [IC50] = 6.8 µg/ml) against COLO-205 cells (in vitro) than OP solution (IC50 = 8.0 µg/ml) and SLN-OP (IC50= 7.5 µg/ml). MBs were also investigated in vivo using Gamma-scintigraphy study. After 48 h study, 99mTc-EuB-FA-SLN-OP confirmed an elevated level of drug in the colonic tumour, which was found significantly (p< 0.0001) higher than that of 99mTc-EuB-SLN-OP. CONCLUSIONS In conclusion, developed MBs formulation (99mTc-EuB-FA-SLN-OP) suggested promising results against therapy of CRC using dual targeting (i.e. ligand-directed and pH-awakened) approach.
