Abstract

In this paper, we step forward in optimizing the efficiency of niosomal systems for carrying curcumin and miR-34a as single-/co-delivery to treat breast cancer. Curcumin, via regulation of p53 protein, affects the molecular signaling pathways and leads to cell death. Likewise, miRNAs, via alternation of the expression of genes, can suppress the development of tumor activities. To conquer and optimize the delivery limitation of curcumin and miRNA, niosomal systems with certain compositions (seven formulations) of Tween-80:Tween-60:cholesterol:DOTAP:PEG are introduced, which enhances the carrier size, surface charge, entrapment efficiency, transfection, and drug release. The results showed that Tween-60 has a significant influence on the entrapment efficiency of the composition. By including the PEG and DOTAP, high enhancements in the overall characteristics of the delivery system were observed. To assess the biological activity of samples, with/without the niosomal delivery system, cytotoxicity, apoptosis, in-vitro, and in-vivo cellular uptake were studied. The recorded data revealed better results from niosomal carriers than their free forms. The best result in single delivery was achieved by miRNA in F6, which had the highest apoptosis, uptake, and smallest tumor volumes under a controlled release. In conclusion, we successfully designed a nanoscale niosomal system to carry drugs and genes to the tumor site to treat cancer cells and provided remarkable data for the scientific society. © 2022, The Author(s).
