O-glycan truncation enhances cancer-related functions of CD44 in gastric cancer

CD44 isoforms are often upregulated in gastric cancer and have been associated with increased metastatic potential and poor survival. To evaluate the functional impact of O-glycan truncation on CD44 we have analysed glycoengineered cancer cell models displaying shortened O-glycans. Here, we demonstrate that induction of aberrant O-glycan termination through various molecular mechanisms affects CD44 molecular features.
