Association of ABCC2 and CDDP-Resistance in Two Sublines Resistant to CDDP Derived from a Human Nasopharyngeal Carcinoma Cell Line
Figure 2
Immunocytochemical staining of ABCC2 expression in three cells (×200; SP method, DAB staining, and counterstaining with hematoxylin). (a) Blank control; (b) Parental cell line CNE2; (c) CDDP-resistant CNE2-CDDP cells; and (d) CDDP-5Fu-resistant CNE2-CDDP-5Fu cells. Black arrow: ABCC2 protein localized in cytoplasm; red arrow: ABCC2 protein localized in nucleus.
