The d-galactopyranosyl ring in direct β-glycosidic link to cholesterol, when formulated into cationic liposomes with the cytofectin 3β[N-(N′,N′,N′,-trimethylammoniumpropane) carbamoyl] cholesterol iodide promotes efficient targeted delivery of a cytotoxic siRNA to the human hepatoblastoma cell line HepG2 via the asialoglycoprotein receptor (ASGP-R). However the receptor-negative human embryonic kidney cell line HEK293 is resistant to transfection under the same conditions.
