Gene expression levels were determined for several cancer markers, including EpCam and KRT19 (CK19) (Figures 5A, B), notable cancer stem cell markers Aldh1a2, Sox9, CD44, and CD133 (Figures 5C–F), tumor suppressor markers Trp53 (TP53) and RB1 (Figures 5G, H), growth factors VEGFA and EGFR (Figures 5I, J), oncogenic driver genes MTOR, Akt1, HRAS, KRAS and Yap1 (Figures 5K–O), and chemokine markers CXCL12 and CXCR4 (Figures 5P, Q). The gene discussed is CXCL12; the disease is cancer.
