Figure 3. Protein expression of a subset of cell cycle components in regenerating livers of Keap1+/+ and Keap1+/− mice. Livers were collected from normal mice and the mice subjected to partial hepatectomy (PH) at the indicated time points after surgery. Western blotting was performed using liver lysates pooled from 3 mice per time point per genotype with antibodies against the proteins indicated. Glyceraldehyde 3-phosphate dehydrogenase (GADPH) was used as a loading control. NL, normal liver.
