Figure 4From: Copper-transporting P-type adenosine triphosphatase (ATP7A) is associated with platinum-resistance in non-small cell lung cancer (NSCLC)Immunohistochemical staining of normal and NSCLC human tissues for ATP7A (magnification, ×400). a, adult normal kidney tissue as positive control; b, adult normal lung tissue as negative Control; c, ATP7A high positive case, almost all of tumor cells showed strong positive reaction in the cytoplasm; d, ATP7A negative case, ATP7A expression was not detectable in the cytoplasm.Back to article page
