Abstract
Background: CXCR4 possesses a critical role in several intracellular events such as chemotaxis, invasion and adhesion, which are associated with metastasis of cancer cell.
Objective: In this study, CXCR4 targeted polymeric nanoparticle was developed for delivering cytotoxic drug and blocking the chemokine induced migration of cells expressing CXCR4.
Method: A peptide which was a linear form of CXCR4 antagonist (LFC131) was attached to PLGA nanoparticles (LFC131-NPs) and PLGA nanoparticles encapsulating DOX (LFC131-DOX-NPs). The cellular binding and internalization of LFC131-DOX-NPs were investigated.
Results: The binding and internalization of LFC131-DOX-NPs were higher and more rapidly compared to unconjugated NPs. LFC131-NPs blocked SDF-1α induced migration of BT-549-Luc cells. MTT assays demonstrated that LFC131-NPs and LFC131-DOX-NPs decreased cell viability in a dose dependent manner in 24, 72 and 120 h incubation.
Conclusion: A treatment concept of blocking breast cancer cell migration from interaction with SDF- 1α by using LFC131-NPs and then attacking breast cancer cells with doxorubicin might increase the efficacy of current breast cancer treatment.
Keywords: Breast cancer, CXCR4, LFC131, metastasis, nanoparticle, PLGA.

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
