Heliyon 2024; 10:e24985. [PMID: 38370262 PMCID: PMC10867619 DOI: 10.1016/j.heliyon.2024.e24985] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/17/2024] [Accepted: 01/17/2024] [Indexed: 02/20/2024] Open
Abstract
Background During the regression of hypertrophic scars, autophagy and apoptosis are the main ways of cell death. Recent investigations demonstrated effective inhibition of resveratrol on hypertrophic scar fibroblasts (HSFs). But its therapeutic value is limited by chemical instability and hydrophobicity, as well as the mechanism of its role in regulation of autophagy and apoptosis remains unknown. Aim of the study We prepared a mesoporous silica nanoparticle laden with resveratrol (MSN@Res) which can effectively improve the solubility and stability of resveratrol. The purpose of this study was to investigate whether MSN@Res regulate autophagy and apoptosis of HSFs via inhibition of ROS/p38/HIF-1α/p53 signaling axis, as to reveal its pharmacological action and target. Materials and methods Network pharmacology, molecular docking, and in vitro assays were carried out in this study. An in vitro model of fibroblasts cultivated in hypoxic and ischemic situations was established to simulate the scar in the proliferative phase. Results MSN@Res surpresses HSFs by reducing physiological autophagy and inducing apoptosis, autosis may be another cell death involed in this process. According to the network pharmacological analysis and molecular docking, the mechanism by which MSN@Res alleviates hypertrophic scar may be closely related to the MAPK signaling pathway. MSN@Res significantly downregulate the expression of HIF-1α and p53 through the inhibition of ROS induced p38-MAPK phosphorylation with corresponding changes in the expression of autophagy and apoptosis related protein. Conclusion MSN@Res is a novel drug delivery system with excellent chemical stability and drug release performance. It can inhibit protective autophagy of fibroblasts in hypoxic environment, and induce the apoptosis and autosis via the ROS -mediated p38-MAPK/HIF-1α/p53 signaling axis.

[PMID: 37924913 DOI: 10.1016/j.ijbiomac.2023.127857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 10/02/2023] [Accepted: 11/01/2023] [Indexed: 11/06/2023]
Abstract
In the current study, we first established that chitosan oligosaccharides (COS) have significant anti-fibrillogenic and fibril-destabilising effects on bovine insulin in vitro that proportionally expand with concentration growth. The obtained data were supported by the Thioflavin T (ThT) assay, circular dichroism (CD), attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy, and atomic force microscopy (AFM). Interestingly, coincubation of insulin with COS in the ratio of 1 to 10 over 48 h at 37 °C leads to full prevention of insulin aggregation, and in the case of preformed fibrils, results in their destabilisation and disaggregation. Moreover, both a cationic polymer of allylamine (PAH) and a sulphated oligosaccharide (CROS) prepared from carrageenan had no inhibitory effect on insulin amyloid formation. Thus, we proposed that COS modulates insulin amyloid formation due to the presence of linear sugar units, the degree of polymerization, and the free amino group providing a positive charge. These findings highlight the potential implications of COS as a promising substance for the treatment of insulin-dependent diabetes mellitus and localised insulin-derived amyloidosis and, moreover, provide a new insight into the mechanism of the anti-diabetic and antitoxic properties of chitosan and chitosan-based agents.

Abstract
OBJECTIVES Resveratrol (Res) was a naturally occurring polyphenol compound. It has various beneficial effects, including anti-inflammatory, anti-oxidant and anti-cancer effects. However, the anti-cancer activity was hindered by its low targeting and drug release performance. Thus, we synthesized transferrin-cathepsin B cleavable peptide modified mesoporous silica nanoparticle encapsulated Res (Tf-Res-MSN). METHODS Res was encapsulated in mesoporous silica nanoparticles (MSN), which was a kind of drug carrier complex. Tf was modified to recognize the cancer cells. Cathepsin B cleavable peptide (Pep) was used to combine Res-MSN complex and Tf to construct the final product. Pep was used as linker and trigger for Res release. KEY FINDINGS The smart nanocarriers were increased the drug release performance of Res in human breast cancer (MCF-7) cells. The physicochemical properties of Tf-Res-MSN were assessed by zeta potential, UV-Prove, diffraction scanning calorimetry (DSC), nitrogen physisorption analysis and transmission electron microscope (TEM). MTT assay, AO and Annexin V-FITC/PI staining were performed to explore the anti-tumour activity of Tf-Res-MSN. The results showed that Tf-Res-MSN significantly decreased cell viability and increased cell apoptosis. The inhibition rate and apoptotic rate of Tf-Res-MSN in MCF-7 cells were 95.75% and 80.8%, respectively. CONCLUSION Our study demonstrated that Tf-Res-MSN was a valuable technique with potential value in breast cancer applications.

Abstract
The misfolding and un-natural fibrillation of proteins/peptides are associated with many conformation diseases, such as human islet amyloid polypeptide (hIAPP) in type 2 diabetes (T2D). Inspired by molecular chaperones maintaining protein homeostasis in vivo, many polymer-based artificial chaperones were introduced to regulate protein/peptide folding and fibrillation. However, the pure polymer chaperones prefer to agglomerate into large-size micelles in the physiological environment and thus lose their chaperone functions, which greatly restricts the application of polymer-based chaperones. Here, we designed and prepared a core-shell artificial chaperone based on a dozen poly-(N-isopropylacrylamide-co-N-acryloyl-O-methylated-l-arginine) (PNAMR) anchored on a gold-nanocluster (AuNC) core. The introduction of the AuNC core significantly reduced the size and enhanced the efficacy and stability of polymer-based artificial chaperones. The PNAMR@AuNCs, with a diameter of 2.5 ± 0.5 nm, demonstrated exceptional ability in maintaining the natively unfolded conformation of protein away from the misfolding and the following fibrillation by directly binding to the natively unfolded monomolecular hIAPP and hence in preventing their conversion into toxic oligomers. More excitingly, the PNAMR@AuNCs were able to restore the natural unfolded conformation of hIAPP via dissolving the β-sheet-rich hIAPP fibrils. Considering the uniform molecular mechanism of protein misfolding and fibrillation in conformation disorders, this finding provides a generic therapeutic strategy for neurodegenerative diseases and other conformation diseases by using PNAMR@AuNC artificial chaperones to restore and maintain the native conformation of amyloid proteins.

Abstract
Monitoring blood glucose levels for diabetic patients is critical to achieve tight glycaemic control. As none of the current antidiabetic treatments restore lost functional β-cell mass in diabetic patients, insulin injections and the use of insulin pumps are most widely used in the management of glycaemia. The use of advanced and intelligent chemical engineering, together with the incorporation of micro- and nanotechnological-based processes have lately revolutionized diabetic management. The start of this concept goes back to 1974 with the description of an electrode that repeatedly measures the level of blood glucose and triggers insulin release from an infusion pump to enter the blood stream from a small reservoir upon need. Next to the insulin pumps, other drug delivery routes, including nasal, transdermal and buccal, are currently investigated. These processes necessitate competences from chemists, engineers-alike and innovative views of pharmacologists and diabetologists. Engineered micro and nanostructures hold a unique potential when it comes to drug delivery applications required for the treatment of diabetic patients. As the technical aspects of chemistry, biology and informatics on medicine are expanding fast, time has come to step back and to evaluate the impact of technology-driven chemistry on diabetics and how the bridges from research laboratories to market products are established. In this review, the large variety of therapeutic approaches proposed in the last five years for diabetic patients are discussed in an applied context. A survey of the state of the art of closed-loop insulin delivery strategies in response to blood glucose level fluctuation is provided together with insights into the emerging key technologies for diagnosis and drug development. Chemical engineering strategies centered on preserving and regenerating functional pancreatic β-cell mass are evoked in addition as they represent a permanent solution for diabetic patients.

Redox-Sensitive and Hyaluronic Acid-Functionalized Nanoparticles for Improving Breast Cancer Treatment by Cytoplasmic 17α-Methyltestosterone Delivery. Molecules 2020; 25:molecules25051181.

Abstract
Novel reduction-responsive hyaluronic acid–chitosan–lipoic acid nanoparticles (HACSLA-NPs) were designed and synthesized for effective treatment of breast cancer by targeting Cluster of Differentiation 44 (CD44)-overexpressing cells and reduction-triggered 17α-Methyltestosterone (MT) release for systemic delivery. The effectiveness of these nanoparticles was investigated by different assays, including release rate, 3-(4,5-Dimethylthiazol-2-Yl)-2,5-Diphenyltetrazolium Bromide (MTT), lactate dehydrogenase (LDH), caspase-3 activity, Rhodamine 123 (RH-123), and Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL). In vitro experiments revealed that Methyltestosterone/Hyaluronic acid–chitosan–lipoic acid nanoparticles (MT/HACSLA-NPs) illustrated a sustained drug release in the absence of glutathione (GSH), while the presence of GSH led to fast MT release. HACSLA-NPs also showed high cellular internalization via CD44 receptors, quick drug release inside the cells, and amended cytotoxicity against positive CD44 BT-20 breast cancer cell line as opposed to negative CD44, Michigan Cancer Foundation-7 (MCF-7) cell line. These findings supported that these novel reduction-responsive NPs can be promising candidates for efficient targeted delivery of therapeutics in cancer therapy.
