It should also be mentioned that decreased activity of GnT-II and -III in the various cell lines do not appear to reduce activity of glycosyltransferases (e.g., GnT-II, -III, and -IV, ST8Sia-II and -IV) that undergo N-glycosylation processing [35] since Kv3.1b expression caused similar trends in N-glycans of the various NB cell lines. The gene discussed is MGAT2; the disease is neuroblastoma.
