ST6GalNAc-I Regulates Tumor Cell Sialylation via NECTIN2/MUC5AC-Mediated Immunosuppression and Angiogenesis in Non-Small Cell Lung Cancer
Proteomic and biochemical analysis indicated that ST6GalNAc-I mediated NECTIN2 sialylation in LUAD cells. ST6GalNAc-I–deficient tumor cells cocultured with T cells are more susceptible to T cell–mediated tumor cell killing. [Journal of Clinical Investigation] Full ArticleGraphical Abstract
JCI ST6GalNAc-I regulates tumor cell sialylation via NECTIN2/MUC5AC-mediated immunosuppression and angiogenesis in non–small cell lung cancer
Glycosylation controls immune evasion, tumor progression, and metastasis. However, how tumor cell sialylation regulates immune evasion remains poorly characterized. ST6GalNAc-I, a sialyltransferase that conjugates sialic acid to the glycans in glycoproteins, was overexpressed in an aggressive-type KPA (KrasG12D/+ Trp53R172H/+ Ad-Cre) lung adenocarcinoma (LUAD) model and patient samples. Proteomic and biochemical analysis indicated that ST6GalNAc…
