FIG. 2.

Effects of cadmium chloride (1, 1.75, or 3 mg/kg) treatment on leakage of ST proteins into IF collected 24 h later. A protein extract of isolated ST from a control rat were run on each gel for normalization. A dose-related increase in the number of proteins in IF samples was observed. (A) Representative 1D gel with arrows indicating protein bands that were quantified. (B) Quantification (mean + SEM) of four proteins (45, 39, 25, and 15 kDa) in IF from the different treatment groups. (n = 8 samples per group except for 1 mg/kg CdCl₂ where n = 5). Samples (two per dose) were run on four different gels, and quantification of proteins was normalized to the ST sample run on each of the gels. *p < 0.05, **p < 0.01, ***p < 0.001 compared with control IF.
