Another study involving Adenoviral- fragile histidine triad (Ad-FHIT) treatment of esophageal cancer cells found overexpression of ST3GAL6 in apoptotic cells compared with non-apoptotic cells, suggesting Ad-FHIT treatment’s role in the inhibition of a sialyltransferase-associated metastasis [80]. Here, FHIT is linked to esophageal cancer.
