Reversal of multi-drug resistance by pSUPER-shRNA-mdr1 in vivo and in vitro

Figure 9 Immunohistochemistry showing green fluorescence in test groups (A) and control groups (B), P-gp expression in test groups (C) and control groups (D), P-gp expression in test groups transfected with in situs injection (E) and intra-abdominal injection of pSUPER-mdr1 (F) (× 200). The transfection ratio for test groups was higher than that for control groups (86.70% vs 35.20%, P < 0.05). The expression of P-gp in test groups was lower than that in control groups (15.75% vs 97.90%, P < 0.05).
