摘要

This study focuses on developing a novel nanoformulation involving hyaluronic acid (HA) coated niosomes (NIOs) containing Fingolimod (FTY720) and quantum dots (QDs) for targeted therapy and metastasis inhibition of triple-negative breast cancer (TNBC). HNio@QDFTY720 NPs were synthesized via thin film hydration method (TFH), resulting in a size of 126.4 nm, a polydispersity index (PDI) of 0.476, and a zeta potential of − 17.6 mV. The encapsulation efficiency was determined to be 98.5%, with drug release studies revealing a pH-sensitive release profile approximately 50% release at pH 7.4, compared to 87.32% at pH 5.8, within 72 h. Cellular uptake studies demonstrated that HNio@QD NPs significantly enhanced drug localization in CD44 + MDA-MB-231 cells. MTT assay indicated that Nio@FTY720 exhibited greater cytotoxicity than the free drug, with HNio@QDFTY720 showing the highest efficacy across all tested concentrations. Annexin V-FITC/PI analysis confirmed induction of massive apoptosis and necrotic cell death, and complete inhibition of cell migration by wound healing assay achieved by HNio@QDFTY720 compared to free drug and control. Bioinformatics study confirmed that majority of Fingolimod target genes were enriched in cell motility, migration and movement and were highly correlated with survival status of breast cancer patients. These findings suggest that niosomal formulation of FTY720 significantly enhances cytotoxic effects against TNBC and represent a promising strategy for improving therapeutic outcomes in metastatic TNBC through targeted drug delivery.
