Other ligands include lactobionic acid bearing β-galactose, targeting ASGPR receptors of HCC cancer cells, AS1411 aptamer targeting nucleolin overexpressed in the nucleus of cancer cells, glycyrrhetinic acid targeting glycyrrhetinic acid receptors often overexpressed on the surface of liver cancer cells, and HDL targeting cells overexpressing SR-B1. The gene discussed is SCARB1; the disease is cancer.
