For example, a viable method for delivering drugs to tumor cells specifically is through the use of albumin nanoparticles, and the mechanism underlying their increased uptake in solid tumors is the binding of albumin to albumin-binding proteins, including membrane-associated 60 kDa glycoprotein (gp60 or albondin) and SPARC-mediated receptor endocytosis [25,48]. The gene discussed is ALB; the disease is neoplasm.
