Table 2 Expression of the 5 multidrug resistance proteins in the capillary walls of tumor tissues

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

Multidrug resistance protein n - + ++ +++ Strongly positive rate (%)
P-gp 30 3 6 12 9 70.00
Topo II 30 23 5 2 0 6.67
GST-π 30 26 3 1 0 3.33
MRP 30 27 2 1 0 3.33
LRP 30 27 3 0 0 0.00
  1. The expression of P-gp is strongly positive in capillary vessels. Low positive expression of LRP, MRP, GST-π and Topo II was observed in capillary vessels. This difference was statistically significant (Rank sum test, P < 0.01)
