Core Tip

Core tip: Gastrointestinal cancer is a group of tumors that affect multiple sites of the digestive system, including the stomach, liver, colon and pancreas. Galectin-1 (Gal-1) is a β-galactoside-binding protein with the ability to cross-link specific glycoconjugates. Accumulating evidence shows that Gal-1 in human gastric cancer, hepatocellular carcinoma, colorectal cancer and pancreatic ductal adenocarcinoma tissues is up-regulated. Moreover, high levels of this galectin correlate with tumor development, aggressiveness, metastasis, immunosupression and angiogenesis. We also highlight that alterations in Gal-1-specific glycoepitopes may be relevant for gastrointestinal cancer progression.
