Low Levels

Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan that exists in living systems, and it is a major component of the extracellular matrix. The hyaluronic acid receptor CD44 is found at low levels on the surface of epithelial, haematopoietic, and neuronal cells and is overexpressed in many cancer cells particularly in tumour initiating cells. HA has been therefore used as ligand attached to HA-lipid-based nanovectors for the active targeting of small or large active molecules for the treatment of cancer. This paper describes the different approaches employed for the preparation, characterization, and evaluation of these potent delivery systems.

There are several mechanisms by which cancer cells develop resistance to treatments, including increasing anti-apoptosis, increasing drug efflux, inducing angiogenesis, enhancing DNA repair and altering cell cycle checkpoints. The drugs are hard to reach curative effects due to these resistance mechanisms. It has been suggested that liposomes based co-delivery systems, which can deliver drugs and genes to the same tumor cells and exhibit synergistic anti-cancer effects, could be used to overcome the resistance of cancer cells. As the co-delivery systems could simultaneously block two or more pathways, this might promote the death of cancer cells by sensitizing cells to death stimuli. This article provides a brief review on the liposomes based co-delivery systems to overcome cancer resistance by the synergistic effects of drugs and genes. Particularly, the synergistic effects of combinatorial anticancer drugs and genes in various cancer models employing multifunctional liposomes based co-delivery systems have been discussed. This review also gives new insights into the challenges of liposomes based co-delivery systems in the field of cancer therapy, by which we hope to provide some suggestions on the development of liposomes based co-delivery systems.

Background: Among all cancers, lung cancer has high mortality among patients in most of the countries in the world. Targeted delivery of anticancer drugs can significantly reduce the side effects and dramatically improve the effects of the treatment. Folate, a suitable ligand, can be modified to the surface of tumor-selective drug delivery systems because it can selectively bind to the folate receptor, which is highly expressed on the surface of lung tumor cells. Objective: This study aimed to construct a kind of folate-targeted topotecan liposomes for investigating their efficacy and mechanism of action in the treatment of lung cancer in preclinical models. Methods: We conjugated topotecan liposomes with folate, and the liposomes were characterized by particle size, entrapment efficiency, cytotoxicity to A549 cells and in vitro release profile. Technical evaluations were performed on lung cancer A549 cells and xenografted A549 cancer cells in female nude mice, and the pharmacokinetics of the drug were evaluated in female SD rats. Results: The folate-targeted topotecan liposomes were proven to show effectiveness in targeting lung tumors. The anti-tumor effects of these liposomes were demonstrated by the decreased tumor volume and improved therapeutic efficacy. The folate-targeted topotecan liposomes also lengthened the topotecan blood circulation time. Conclusion: The folate-targeted topotecan liposomes are effective drug delivery systems and can be easily modified with folate, enabling the targeted liposomes to deliver topotecan to lung cancer cells and kill them, which could be used as potential carriers for lung chemotherapy.

Background: Many efforts have been explored in the last decade to treat colon cancer but nanoparticulate drug delivery systems are making a vital contribution in the improvement of drug delivery to colon cancer cells. Objective: In this review, we attempt to highlight recent advancements in the development of novel drug delivery systems of nanoparticles for the targeted drug delivery to colon. Polymers like Epithelial Cell Adhesion Molecule (EpCAM) aptamer chitosan, Hyaluronic Acid (HA), Chitosan (CS)– Carboxymethyl Starch (CMS), silsesquioxane capped mesoporous silica, Near IR (NIR) fluorescent Human Serum Albumin (HAS), poly(ethylene glycol)-conjugated hyaluronic acid etc. have been discussed by employing various anticancer drugs like doxorubicin, oxaliplatin, paclitaxel, 5-fluorouracil etc. Conclusion: These novel drug delivery systems have been determined to be more efficacious in terms of stability, sustained and targeted drug delivery, therapeutic efficacy, improved bioavailability and enhanced anticancer activity.
