一般說明

Tn 抗原是一种截短的 O -聚糖，在结直肠癌（CRC）中常见。通常在癌细胞中高水平表达。Tn 抗原体积小，结构简单。其在人体内具有非生理性聚糖结构，因此可能被免疫系统识别为异物。

生化／生理作用

Tn 抗原通过 H-Ras 介导的上皮间质转换刺激结直肠癌转移。作为几种重要复合物 O -聚糖的前体。携带 Tn 抗原的所有谱系中的血细胞亚群导致一种称为 Tn 综合征的血液疾病。

The Tn antigen is a neoantigen abnormally expressed in many human carcinomas and expression correlates with metastasis and poor survival. To explore its biomarker potential, new antibodies are needed that specifically recognize this antigen in tumors. Here we generated two

Immature truncated O-glycans such as Tn antigen are frequently detected in human colorectal cancer (CRC); however, the precise pathological consequences of Tn antigen expression on CRC are unknown. T-synthase is the key enzyme required for biosynthesis of mature O-glycans. Here

Colorectal cancer is the third most common cancer type worldwide. It is characterized by a high expression of aberrantly glycosylated ligands, such as the Tn antigen (GalNAcα1-Ser/Thr), which is a major ligand for the C-type lectin macrophage galactose-type lectin (MGL).

Mucin-type O-linked glycosylation, a posttranslational modification affecting the stability and biophysical characteristics of proteins, requires C1GalT1 (T synthase) and its obligate, X-linked chaperone Cosmc. Hypomorphic C1GalT1 mutations cause renal failure via not yet established mechanisms. We hypothesize that impaired Cosmc-dependent
