Effect of cysteine compounds on TGF-β levels in the liver. Tissue lysates was evaluated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis as described in the Materials and Methods. Animals were treated as described in Fig. 2. The relative increases of the intensity compared with the sham group are expressed as percentages. Values are means ± SEM (n = 5–8). *p<0.05 vs the CCl₄ group. ^††p<0.01 vs the sham group.
