Abstract
Background: One of the major abundant proteins in the nucleous is nucleolin that overexpressed on the cytoplasmic membrane of malignant and endothelial cells and makes it as a promising condidate for targeted drug delivery.
Objectives: In this study, doxorubicin (Dox) as a chemotherapy drug was entrapped into the Poly lacticco- glycolic acid (PLGA)-based nanoparticles (NPs). Then, the targeting ability of anti nucleolin AS1411 aptamer-targeted Dox-encapsulated PLGA-based NPs (AS1411-NPs) was investigated in high nucleolin-expressing C26 colon carcinoma and rat C6 glioma cell lines compared with low nucleolinexpressing mouse L929 cell line.
Methods: We recently first assessed the existence of cell surface nucleolin of these three different cell lines by immunocytochemistry method. We found that a large amount of nucleolin was localized in the cytoplasmic membrane of C26 and C6 cell lines, with a very smaller amount on the surface of L929 cell line.
Results: As a result, more rapidly internalization of AS1411-NPs into the C26 and C6 cells compared with L929 cells was verified.
Conclusion: We think that AS1411-NPs, as a ligand, first bind to nucleolin, as a receptor, and then the receptor-ligand complex is more efficiently incorporated into the high nucleolin-expressing cell lines through receptor-mediated endocytosis pathway.
Keywords: Nucleolin, AS1411 aptamer, targeted delivery, internalization, PLGA, doxorubicin.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
