A hyperglycosylated recombinant human coagulation factor IX (FIX) fusion protein, a preparation method therefor, and use thereof. The fusion protein sequentially comprises, from N- to C-terminus, a human FIX, a flexible peptide linker, at least one human chorionic gonadotropin β subunit carboxy-terminal peptide rigid unit, and a half-life extending moiety. The fusion protein has a biological activity similar to that of the recombinant FIX, an extended in vivo activity half-life, and reduced immunogenicity, so as to improve pharmacokinetics and pharmacodynamics.

This disclosure relates to nanoparticles coated with fusion proteins comprising a domain that binds a cancer marker and a domain comprising a toxic polypeptide. In certain embodiments, the targeted cancer marker is urokinase plasminogen activator receptor (uPAR) insulin-like growth factor 1 receptor (IGF1R), EGFR, HER2, and/or other member of the ErbB family of receptors. In certain embodiments, the molecule that binds a cancer marker is an amino terminal fragment of uPA or variant capable of binding uPAR and/or IGF1 or variant capable of binding IGF1R. In certain embodiments, the toxic polypeptide is a bacterial exotoxin.
