Figure 1: Protein expression of D1R in renal cortex of control and PAN-NS rats, seven and fourteen days after injection. The intensity of D1R bands (50 KDa) was quantified after normalization for -actin protein expression (43 KDa) and is expressed as percentage of control. Bars represent means of 4 to 5 experiments per group and error bars represent SE. * , significantly different from values in control rats.
