FIGURE 3. Relationship between expression of Pgp, MRP, or LRP and ^99mTc-MIBI L/Nd in lung cancer. (A) L/Nd correlated inversely with density of Pgp expression. Statistically significant difference in L/Nd was found between Pgp (-) group and Pgp (++) group. (B) No significant difference (n.s.) in L/Nd was found among MRP (++), MRP (+), and MRP (-) groups. (C) No significant difference in L/Nd was found among LRP (++), LRP (+), and LRP (-) groups.
