SLC1A3 and cancer: Slc1a3 is upregulated in actively cycling SCs of the skin interfollicular epidermis, hair follicles and sebaceous glands and plays a role in SC/progenitor cell activation (Reichenbach et al., 2018; Sada et al., 2016) and promotes cell proliferation and survival of cancer cells under conditions of nutrient starvation or hypoxia (Garcia-Bermudez et al., 2018; Tajan et al., 2018).
