Galectin-14, a primate-specific oncofetal protein, impairs anti-tumour immunity in hepatocellular carcinoma by driving elevated heparan sulphate modification

Listen to this summary

The authors investigate the role of heparan sulphate (HS) modification in the progression of hepatocellular carcinoma (HCC) and its impact on anti-tumor immunity. They identify galectin-14, a primate-specific oncofetal protein, as a key regulator that enhances HS synthesis, leading to T cell exhaustion and poor patient prognosis. This study highlights galectin-14's potential as both a diagnostic marker and a therapeutic target in HCC.
