LGALS3 and neoplasm: The selective interaction of a disaccharide called Thomas Friedrich antigen (TFag) with specific tumor cells displaying Gal‐3 lectin had a cytotoxic effect on the targeted cells: a conjugate of small AuPs coated with TFag via an amino acid linker was synthesized, and an approximately 100‐fold higher cytotoxicity toward the Gal‐3‐positive cells was achieved compared to monomeric units.274 The main cytotoxic effect of the TFag relied on apoptosis induced by an inhibited Gal‐3 signaling,274 but it is anticipated that the TFag targeting may also work well in drug delivery.
