LRPAP1 and neoplasm: In vitro studies suggested that FA-NLC-RAP exhibited a higher degree of internalization in cancer cells (MCF-7) than in normal cells (MCF-10A), demonstrating the potential of folic acid as a ligand for promoting active targeting of RAP for breast cancer cells through folate receptors overexpressed in tumor cells FA-NLC-RAP significantly reduced tumor cell viability, similarly to that observed with the RAP solution.
