For example, a reduced level of α2,6-sialylation of complex-type N-glycans or the presence of core 2 mucin-type O-glycans and ganglioside GM1 play crucial roles in the growth regulation of activated T cells and tumor cells by Gal-1 (Kopitz et al. 2001; Cabrera et al. 2006; Valenzuela et al. 2007; Wang et al. 2009; Earl et al. 2010; Amano et al. 2012). This evidence concerns the gene MUC5AC and neoplasm.
