Carbohydrate polymer-based nanoparticles in curcumin delivery for cancer therapy

The application of natural products for cancer treatment has a long history. The safety and multifunctionality of naturally occurring substances have made them appropriate for cancer treatment and management. Curcumin affects multiple molecular pathways and is advantageous for treating both hematological and solid tumors. Nonetheless, the effectiveness of curcumin in vivo and in clinical studies has faced challenges due to its poor pharmacokinetic profile. Consequently, nanoparticles have been developed for the administration of curcumin in cancer treatment. The nanoparticles can enhance the distribution of curcumin in tissues and increase its therapeutic effectiveness. Furthermore, nanoparticles expand the uptake of curcumin in cancer cells, leading to increased cytotoxicity. Carbohydrate polymer-based nanoparticles provide a promising solution for the delivery of curcumin in cancer treatment by addressing its low solubility, limited bioavailability, and quick degradation. These biodegradable and biocompatible carriers, originating from polymers such as chitosan, hyaluronic acid, and alginate, protect curcumin, improving its stability and allowing for controlled release. Targeting ligands for functionalization provides selective and specific distribution to the tumor cells, enhancing therapeutic effectiveness and reducing off-target impacts. Their capacity to encapsulate curcumin with other agents allows for synergistic therapies, enhancing anticancer results even more. The adjustable characteristics of carbohydrate nanoparticles, along with their minimal toxicity, develop a revolutionary, functional and safe platform.

Hyaluronic acid helps target tissues more effectively, especially in cancer environments where there are high levels of hyaluronic acid receptors. Alginate-based systems also enhance drug delivery by being biocompatible and degradable, making them ideal choices for advanced therapeutic uses. Moreover, these particles hold potential for overcoming resistance to multiple drugs and boosting the body's immune reaction to tumors through precise delivery and decreased side effects of chemotherapy drugs. This review delves into the possibilities of using carbohydrate polymer-functionalized nanoparticles and their impact on enhancing the efficacy of cancer treatment.

Complexed hyaluronic acid-based nanoparticles in cancer therapy and diagnosis: Research trends by natural language processing

Hyaluronic acid (HA) is a popular surface modifier in targeted cancer delivery due to its receptor-binding abilities. However, HA alone faces limitations in lipid solubility, biocompatibility, and cell internalization, making it less effective as a standalone delivery system. This comprehensive study aimed to explore a dynamic landscape of complexation in HA-based nanoparticles in cancer therapy, examining diverse aspects from influential modifiers to emerging trends in cancer diagnostics. We discovered that certain active substances, such as 5-aminolevulinic acid, adamantane, and protamine, have been on trend in terms of their usage over the past decade. Dextran, streptavidin, and catechol emerge as intriguing conjugates for HA, coupled with nanostar, quantum dots, and nanoprobe structures for optimal drug delivery and diagnostics. Strategies like hypoxic conditioning, dual responsiveness, and pulse laser activation enhance controlled release, targeted delivery, and real-time diagnostic techniques like ultrasound imaging and X-ray computed tomography (X-ray CT). Based on our findings, conventional bibliometric tools fail to highlight relevant topics in this area, instead producing merely abstract and broad-meaning keywords. Extraction using Named Entity Recognition and topic search with Latent Dirichlet Allocation successfully revealed five representative topics with the ability to exclude irrelevant keywords. A shift in research focuses from optimizing chemical toxicity to particular targeting tactics and precise release mechanisms is evident. These findings reflect the dynamic landscape of HA-based nanoparticle research in cancer therapy, emphasizing advancements in targeted drug delivery, therapeutic efficacy, and multimodal diagnostic approaches to improve overall patient outcomes.

Bio-Inspired Nanodelivery Platform: Platelet Membrane-Cloaked Genistein Nanosystem for Targeted Lung Cancer Therapy

Background

Genistein (Gen), a natural polyphenolic compound, has emerged as a promising candidate for lung cancer treatment. However, the potential clinical application of Gen is limited due to its poor solubility, low bioavailability, and toxic side effects. To address these challenges, a biomimetic delivery platform with cell membranes derived from natural cells as carrier material was constructed. This innovative approach aims to facilitate targeted drug delivery and solve the problem of biocompatibility of synthetic materials.

Methods

First, the liposomes (LPs) loaded with Gen (LPs@Gen) was prepared using the ethanol injection method. Subsequently, PLTM-LPs@Gen was obtained through co-extrusion after mixing platelet membrane (PLTM) and LPs@Gen. Additionally, the biological and physicochemical properties of PLTM-LPs@Gen were investigated. Finally, the targeting ability, therapeutic efficacy, and safety of PLTM-LPs@Gen for lung cancer were evaluated using both a cell model and a tumor-bearing nude mouse model.

Results

The optimal preparation ratio for LPs@Gen was Gen: soybean lecithin: cholesterol: DSPE-PEG2000 (3:30:5:10, mass ratio), while the ideal fusion ratio of LPs@Gen and PLTM was 1:1. The particle size of PLTM-LPs@Gen was 108.33 ± 1.06 nm, and the encapsulation efficiency and drug loading were 94.29% and 3.09% respectively. Gen was released continuously and slowly from PLTM-LPs@Gen. Moreover, PLTM-LPs@Gen exhibited good stability within one week. The results of in vitro cellular uptake and in vivo distribution experiments indicated that the carrier material, PLTM-LPs, has the immune escape ability and tumor targeting ability. Consequently, it showed better therapeutic effects than free drugs and traditional LPs in vitro and in vivo tumor models. In addition, safety experiments demonstrated that PLTM-LPs@Gen possesses good biocompatibility.

Conclusion

Biomimetic nanomedicine provides a new strategy for the precision treatment of lung cancer in clinical practice.

Herein, LBNPs are classified into liposomes and cell membrane-based nanoparticles (CMNPs), each with unique advantages and challenges. Conventional LBNPs possess drawbacks such as poor targeting, quick clearance, and limited biocompatibility. One of the possible alternatives to overcome these challenges is surface modification of nanoparticles (NPs) with materials such as polyethylene glycol (PEG), aptamers, antibody fragments, peptides, CD44, hyaluronic acid, folic acid, palmitic acid, and lactoferrin. Thus, the main focus of this review will be on the different surface modifications that enable LBNPs to have beneficial properties for DD, such as enhancing mass transport properties, immune evasion, improved stability, and targeting. Moreover, various CMNPs are explored used for DD derived from cells such as red blood cells (RBCs), platelets, leukocytes, cancer cells, and stem cells, highlighting their unique natural properties (e.g., biocompatibility and ability to evade the immune system). This discussion extends to the biomimicking of hybrid NPs accomplished through the surface coating of synthetic (mainly polymeric) NPs with different cell membranes. This review aims to provide a comprehensive resource for researchers on recent advances in the field of surface modification of LBNPs and CMNPs. Overall, this review provides valuable insights into the dynamic field of lipid-based DD systems.

Cancer cell membrane-camouflaged paclitaxel/PLGA nanoparticles for targeted therapy against lung cancer

Paclitaxel (PTX) is a first-line drug for the treatment of lung cancer, but its targeting and therapeutic effect are unsatisfactory. Herein, lung cancer cell (A549) membrane biomimetic PTX-loaded poly (lactic-co-glycolic acid) (PLGA) nanoparticles (AM@PTX-NPs) were constructed to eliminate the shortcomings of PTX. The AM@PTX-NPs were successfully prepared with a high drug loading efficiency (10.90±0.06 %). Moreover, transmission electron microscopy, SDS-PAGE, and western blotting proved that AM@PTX-NPs were spherical nanoparticles camouflaged by the A549 cell membrane. Both in vitro and in vivo assays revealed that the AM@PTX-NPs displayed outstanding targeting capacity due to A549 membrane modification. The cytotoxicity experiment showed that the developed biomimetic formulation was able to effectively reduce the proliferation of A549 cells. Moreover, AM@PTX-NPs exhibited a significant tumor growth inhibition rate (73.00 %) with good safety in the tumor-bearing mice, which was higher than that of the PTX-NPs without A549 membrane coating (37.39 %). Overall, the constructed bioinspired vector could provide a novel platform for the PTX delivery and demonstrated a promising strategy for the targeted cancer treatment.

Tumor metastasis, the apex of cancer progression, poses a formidable challenge in therapeutic endeavors. Circulating tumor cells (CTCs), resilient entities originating from primary tumors or their metastases, significantly contribute to this process by demonstrating remarkable adaptability. They survive shear stress, resist anoikis, evade immune surveillance, and thwart chemotherapy. This comprehensive review aims to elucidate the intricate landscape of CTC formation, metastatic mechanisms, and the myriad factors influencing their behavior. Integral signaling pathways, such as integrin-related signaling, cellular autophagy, epithelial-mesenchymal transition, and interactions with platelets, are examined in detail. Furthermore, we explore the realm of precision nanomedicine design, with a specific emphasis on the anoikis‒platelet interface. This innovative approach strategically targets CTC survival mechanisms, offering promising avenues for combatting metastatic cancer with unprecedented precision and efficacy. The review underscores the indispensable role of the rational design of platelet-based nanomedicine in the pursuit of restraining CTC-driven metastasis.

Biomimetic platelet-like nanoparticles enhance targeted hepatocellular carcinoma therapy

Curcumin (CUR) is a promising natural product for hepatocellular carcinoma (HCC) therapy. However, its clinical application has been limited by some issues such as rapid clearance and inadequate tumor accumulation. To address these drawbacks, we developed platelet membrane-coated CUR-loaded PLGA nanoparticles (PCPNPs). In this work, due to the bioinspired strategy, the PCPNPs exhibited immune evasion, prolonged circulation, and improved accumulation at tumor sites compared to the traditional CUR formulation. The superior tumor targeting of PCPNPs was likely due to the interactions between platelet P-selectin and tumoral CD44. Furthermore, both in vitro and in vivo assays revealed that the PCPNPs showed outstanding anticancer efficacy without obvious toxicity. Therefore, PCPNPs represent a biosafe and promising anti-tumor strategy, overcoming the limitations associated with CUR. These findings not only contribute to the advancement of natural compound nano-formulation but also open new avenues for targeted cancer treatment.
