Effect of CdCl2 on p53 and p21Cip1/WAF-1 protein expression. HepG2 homogenated proteins (50 μg/lane) were separated on 12% gels or 10% gels, transferred onto nitrocellulose membrane, and probed for p21Cip1/WAF-1 or p53 protein expression, respectively. Representative Western blots are shown. Parallel gels stained with Coomassie Blue G250 for equal protein loading evaluation were performed.
