SLC4A7 and cancer: Since SLC4A7 is also expressed in the smooth muscle and endothelial cells of the vascular wall (Boedtkjer et al., 2008) and is important for maintaining vasomotor responsiveness (Boedtkjer et al., 2011) and possibly arterial structure (Boedtkjer and Aalkjaer, 2013), it is conceivable that SLC4A7 may also in part affect cancer development by modifying blood perfusion of tumors.
