Figure 2 Northern blot analysis. Twenty micrograms of total RNA from control (lane 1) and diabetic rat cortex kidneys after 15 days (lane 2) and 99 days (lane 3) of diabetic course. The blot was probed with 32P-α-labeled mdr 1 clone (upper panel) and alpha-actin probe (lower panel). Arrows correspond to 28 S and 18 S RNA.

Figure 3 Western blot analysis. Twenty-five micrograms of control (lane 1) and diabetic (lane 2) cortex rat kidney proteins were prepared at day 99, and run on a 7.5 polyacrylamide gel. The blot was probed with the MRK 16 monoclonal antibody and revealed using the alkaline phosphatase system. Arrows correspond to 132 kDa and 84 kDa.

Figure 4 Northern blot analysis. Twenty micrograms of total RNA from control (lane 1) and diabetic rat cortex kidneys after 15 days (lane 2) and 99 days (lane 3) of diabetic course. The blot was probed with 32P-α-labeled βPP clone (upper panel) and α-actin probe (lower panel). Arrows correspond to 28 S and 18 S RNA.

Figure 5 Western blot analysis. Twenty-five micrograms of control (lane 1) and diabetic (lane 2) cortex rat kidney proteins were prepared at day 99, and run on a 7.5 polyacrylamide gel. The blot was probed with the Alz 90 monoclonal antibody and revealed using the chemoluminescence system. Arrows correspond to 84 kDa and 47 kDa.
