Aberrant glycosylation is a hallmark in various cancers and GALNT14, as a glycosyltransferase in the Golgi membrane, has been shown to promote lung-specific breast cancer metastasis by suppressing the bone morphogenetic protein signalling and activating the fibroblast growth factors to recruit macrophages for its metastatic microenvironment [70]. The gene discussed is GALNT14; the disease is breast cancer.
