Targeting Sialylation Enhances the Therapeutic Efficacy of the Nectin-4-Targeted Antibody-Drug Conjugate Enfortumab Vedotin in Bladder Cancer. [Abstract]

2025 Oct 9. PMID: 41066596

2,3-Dehydro-2-deoxy-N-acetylneuraminic acid purchased from MedChemExpress. Usage Cited in: Cancer Res. 2025 Oct 9. [Abstract]

Coimmunoprecipitation assays were performed to explore the Ub levels of exogenous Flag-tagged Nectin-4 in KU-19-19 cells with or without transfection of HA-tagged Ub and the treatment of MG132 (10 μmol/L), 2,3-Dehydro-2-deoxy-N-acetylneuraminic acid (Neu5Ac2en) (80 μmol/L), or P-3Fax-Neu5Ac (200 μmol/L). The expression and Ub levels of Flag-tagged Nectin-4 were detected by Western blot. All cell samples were treated with MG132 (10 μmol/L) before collecting cells. The results showed that after the addition of Neu5Ac2en to inhibit neuraminidases and enhance sialylation in bladder cancer cells, there was an increase in the ubiquitination levels of exogenous Nectin-4.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
