Overexpression of some glycoproteins, for example, Mucin 1, correlates with the development of aggressive cancers (Knelson et al., 2014; Mitchell and King, 2014; Paszek et al., 2014; Mallard and Tiralongo, 2017; Barnes et al., 2018; Kuo et al., 2018; Vitale et al., 2019; Ahrens et al., 2020). The gene discussed is MUC1; the disease is cancer.
