ALDH1A1 and cancer: In bladder cancers, high grade tumors were enriched in mesenchymal markers (e.g., Vimentin, Collagen α-1I), basal and cancer stem cell markers [e.g., Aldehyde dehydrogenase 1 family member A1 (ALDH1A1) and Bcl-2-associated X protein (BAX)], proteins associated with cell migration (e.g., Fibronectin 1 and Vitronectin), and EMT inducers (e.g., TGF-β1) [103].
