Quan et al. [303] developed human serum albumin (HSA)-coated Fe2O3 NPs (HINP) conjugated with DOX and observed that in a 4T1 murine breast cancer xenograft model, DOX-HINP induced a reduction in tumor growth comparable to Doxil (a liposome-based DOX formula used as a treatment for various types of cancer) and superior to free Dox. The gene discussed is ALB; the disease is breast cancer.
