Thymoquinone-PLGA-PF68 Nanoparticles Induce S Phase Cell Cycle Arrest and Apoptosis, Leading to the Inhibition of Migration and Colony Formation in Tamoxifen-Resistant Breast Cancer Cells

In this study, a significant functional change in TamR MCF-7 cells induced by the TQ nanoparticles was observed. The unique incorporation of TQ into the PLGA-PEG and Pluronics F68 formulation preserved its bioactivity, thereby reducing the migratory and proliferative traits of drug-resistant cells. This discovery may pave the way for exploring the application of biocompatible polymeric TQ nanoparticles as a novel therapeutic approach in future studies pertaining to resistant breast cancer.
