Table 3 Expression of the 5 multidrug resistance proteins in the interstitial cells

From: Expression and clinical significance of multidrug resistance proteins in brain tumors

Multidrug resistance protein n - + ++ +++ Strongly positive rate(%)
P-gp 30 3 13 10 4 46.67
Topo II 30 21 3 2 4 20.00
GST-π 30 13 14 2 1 10.00
MRP 30 24 4 1 1 6.67
LRP 30 22 6 1 1 6.67
  1. The expression of resistance proteins in interstitial cells are similar to the tumor cells. The positive expression of P-gp is highest, the difference was statistically significant (Rank sum test, P < 0.05)
