Abstract
Background: This study investigates how mP6/Rg3 micelles modulate ABCB1 expression to induce ferroptosis in oral cancer stem cells (CSC) and enhance oral cancer outcomes.
Methods: Micelles targeting CD44 peptide P6 were prepared and characterized using TEM and immunofluorescence. Biocompatibility was evaluated through LIVE/DEAD staining and CCK-8 assays. Impact on oral cancer CSC was assessed through in vitro and OSCC mouse model studies using transcriptomic profiling, proteomic analysis, and metabolomic screening.
Results: mP6/Rg3 micelles exhibited good biodegradability, inhibiting CSC proliferation and migration. Integrated multi-omics analysis highlighted ABCB1 as a pivotal modulator in OSCC. Functional assays in cell and animal models validated micelles promote ferroptosis in CSC by inhibiting ABCB1, improving OSCC pathology.
Conclusions: Targeting ABCB1 with mP6/Rg3 micelles and regulating CD44 presents a promising approach to suppress oral cancer progression by impacting CSC and tumor metabolic pathways. This study offers crucial molecular insights for new therapeutic strategies in oral cancer treatment.
期刊介绍:
Cell Biology and Toxicology (CBT) is an international journal focused on clinical and translational research with an emphasis on molecular and cell biology, genetic and epigenetic heterogeneity, drug discovery and development, and molecular pharmacology and toxicology. CBT has a disease-specific scope prioritizing publications on gene and protein-based regulation, intracellular signaling pathway dysfunction, cell type-specific function, and systems in biomedicine in drug discovery and development. CBT publishes original articles with outstanding, innovative and significant findings, important reviews on recent research advances and issues of high current interest, opinion articles of leading edge science, and rapid communication or reports, on molecular mechanisms and therapies in diseases.
