TNFSF10 and melanoma: The design of core-shell ternary systems consisting of fluorinated polymers (PFs) binding with a plasmid (pDNA) and a negatively-charged multifunctional RRPH (arginyl-glycyl-aspartic acid (RGD)-cell-penetrating peptide (R8)-PEG-sodium hyaluronate/(RGD-R8-PEG-HA) shell, also known as RRPH/PF/pDNA (RRPHC) ternary complex or HA (sodium hyaluronate) shell, also known as HA/PF/pDNA (HAC) ternary complex for the delivery of pUNO1-mTRAIL (mouse TRAIL) plasmid was successful in causing apoptosis in B16F10 mouse melanoma cell line.
