Current Status

Although progress is observed in cancer treatment, this disease continues to be the second leading cause of death worldwide. The current understanding of cancer indicates that treating cancer should not be limited to killing cancer cells alone, but that the target is the complex tumor microenvironment (TME). The application of nanoparticle-based drug delivery systems (DDS) can not only target cancer cells and TME, but also simultaneously resolve the severe side effects of various cancer treatment approaches, leading to more effective, precise, and less invasive therapy. Nanoparticles based on proteins derived from silkworms’ cocoons (like silk fibroin and sericins) and silk proteins from spiders (spidroins) are intensively explored not only in the oncology field. This natural-derived material offer biocompatibility, biodegradability, and simplicity of preparation methods. The protein-based material can be tailored for size, stability, drug loading/release kinetics, and functionalized with targeting ligands. This review summarizes the current status of drug delivery systems’ development based on proteins derived from silk fibroin, sericins, and spidroins, which application is focused on systemic cancer treatment. The nanoparticles that deliver chemotherapeutics, nucleic acid-based therapeutics, natural-derived agents, therapeutic proteins or peptides, inorganic compounds, as well as photosensitive molecules, are introduced.

Background: Increasing the bioavailability of peptide or protein drugs has always been an essential topic in pharmacy. Milk exosomes as a carrier for oral drug delivery systems have begun to attract attention in recent years. The application of oral milk exosomes carriers to peptide drugs such as liraglutide is worth trying. Objective: Milk-derived exosomes are used in this study to encapsulate the GLP-1 receptor agonist liraglutide. It also explored the feasibility of using this drug delivery system for oral biomolecules delivery in the future. Methods: The size and morphology of milk exosomes were characterized. The gastrointestinal stability of milk exosomes was evaluated in a dialysis bag. The cellular uptake of milk exosomes in an intestinal cell was observed. Six drug loading methods have been evaluated and compared preliminarily, and they are the incubation method, sonication method, extrusion method, freeze-thaw cycles method, saponin-assisted method, and electroporation method. Results: As demonstrated in this study, milk exosomes showed significant stability in the gastrointestinal environment and excellent affinity with intestinal cells, indicating their unique benefits used for oral drug delivery. Effective drug loading method for exosomes is challenging. Among the six drug loading methods used in this study, the liraglutide-Exo prepared by the extrusion method obtained the most significant drug load, which was 2.45 times the direct incubation method. The liraglutide-Exo obtained by the freeze-thaw cycles method has the slightest morphological change. Conclusion: The study showed milk exosome-based oral drug delivery systems are promising.

: Currently, despite many active compounds have been introduced to the treatment, cancer remains one of the most vital causes of mortality and reduced quality of life. Conventional cancer treatments may have undesirable consequences due to the continuously differentiating, dynamic and heterogeneous nature of cancer. Recent advances in the field of cancer treatment have promoted the development of several novel nanoformulations. Among them, the lipid coated nanosized drug delivery systems have gained an increasing attention by the researchers in this field owing to the attractive properties such as high stability and biocompatibility, prolonged circulation time, high drug loading capacity and superior in vivo efficacy. They possess the advantages of both the liposomes and polymeric nanoparticles which makes them a chosen one in the field of drug delivery and targeting. Core-shell type lipid-coated nanoparticle systems, which provide the most prominent advantages of both liposomes such as biocompatibility and polymeric/inorganic nanoparticles such as mechanic properties, offer a new approach to cancer treatment. This review discusses design and production procedures used to prepare lipid-coated nanoparticle drug delivery systems, their advantages and multifunctional role in cancer therapy and diagnosis, as well as the applications they have been used in.

Recently, using gelatin nanoparticles as a biocompatible carrier in drug delivery systems is growing up. Drug delivery is one of the most common applications of nanoparticles in cancer treatment in order to optimize the drug efficiency. In this study, gelatin nanoparticles were firstly synthesized and loaded with tamoxifen that subsequently characterized by SEM, TGA and FT-IR analyses. The approximate drug loading efficiency was calculated about 17.43% for tamoxifen-loaded gelatin (TG). Then, the effect of TG on apoptosis induction and cytotoxicity of MCF-7 cell line was evaluated and compared with flow cytometry and MTT assay. The MTT results showed that tamoxifen and TG nanoparticles could inhibit the proliferation of MCF-7 cells in a dose-responsive manner, with an IC[Formula: see text] of IC[Formula: see text] of 200 [Formula: see text]g/mL and 50 [Formula: see text]g/mL after 24[Formula: see text]h and 48[Formula: see text]h, respectively. Moreover, from flow cytometric results, it can be suggested that TG nanoparticles are more potent in inducing apoptosis and cell death through programmed cell death. Actually, TG nanoparticles primarily increased the early apoptotic cells during the 24-h incubation period Our results revealed that tamoxifen-loaded gelatin nanoparticles are more potent than tamoxifen alone. These findings support the use of tamoxifen-loaded gelatin nanoparticles in target-specific therapy for cancer treatment.

The broad diversity of structures and the presence of numerous functional groups available for chemical modifications represent an enormous advantage for the development of safe, non-toxic, and cost-effective micellar drug delivery systems (DDS) based on natural biopolymers, such as polysaccharides, proteins, and peptides. Different drug-loading methods are used for the preparation of these micellar systems, but it appeared that dialysis is generally recommended, as it avoids the formation of large micellar aggregates. Moreover, the preparation method has an important influence on micellar size, morphology, and drug loading efficiency. The small size allows the passive accumulation of these micellar systems via the permeability and retention effect. Natural biopolymer-based micellar DDS are high-value biomaterials characterized by good compatibility, biodegradability, long blood circulation time, non-toxicity, non-immunogenicity, and high drug loading, and they are biodegraded to non-toxic products that are easily assimilated by the human body. Even if some recent studies reported better antitumoral effects for the micellar DDS based on polysaccharides than for commercial formulations, their clinical use is not yet generalized. This review is focused on the studies from the last decade concerning the preparation as well as the colloidal and biological characterization of micellar DDS based on natural biopolymers.
