SOAT1 and cancer: Signalling pathways associated with cancer stem cell function (MAPK, Wnt, JAK-STAT [35], TGF-β and PPAR [36]), metabolism, cell adhesion, cell proliferation, cell death, transmembrane transport and extracellular matrix organisation were among some of the most altered biological processes that likely underpin tumour aggression and decreased survival in these patients (Fig. 4b, c).
