The developed drug vehicle is composed of a cell penetrating peptide (SynB1) to promote tumor and cellular uptake; thermally responsive elastin-like polypeptide (ELP); and the (6-maleimidocaproyl) hydrazone derivative of doxorubicin (DOXO-EMCH) containing a pH-sensitive hydrazone linker that releases dox in the acidic tumor environment. Here, NR5A1 is linked to neoplasm.
