Microarray analysis of HNSCC cells treated with ICG-001 and biochemical analyses revealed inhibition of protein N-glycosylation via DPAGT1 (manuscript in preparation), suggesting that DPAGT1/N-glycosylation functioned in the β-catenin/CBP branch of the Wnt/ β-catenin pathway. Here, DPAGT1 is linked to head and neck squamous cell carcinoma.
