3.2.1.113 diagnostics MAN1C1 may be a useful prognostic biomarker and potential therapeutic target in clear cell renal cell carcinoma, with the potential to lead to better outcomes for patients with these poor prognosis malignancies 751168 3.2.1.113 drug development development of anti-cancer therapies 677921 3.2.1.113 medicine the class I alpha-mannosidases can be used as drug targets to inhibit the demannosylation of HBV, thereby improving the binding of the virus to DC-SIGN and disrupting the immune tolerance to prevent and treat viral infection 752329 3.2.1.113 pharmacology in triple KO (MAN1A1, MAN1A2, and MAN1B1) cells, Man9GlcNAc2 and Man8GlcNAc2 are the major N-glycan structures. The N-glycan structures on recombinant proteins expressed in triple KO cells are simplified and changed from complex types to high-mannose types at the protein level. The triple KO HEK293 cells are suitable for producing recombinant proteins, including lysosomal enzymes with high-mannose-type N-glycans. This approach should accelerate the production of biopharmaceutical proteins with homogenous glycans 751118
