Detection of the expression levels of ATF2 and Cdk4 in mouse skin epidermal tissues at the end of the skin carcinogenesis study.

<p>Results were obtained from both the antibody microarray analysis (left panel) and Western blot analysis (right panel). Tissues from each individual mouse were pooled together and there were four repeats in each data group. DMSO, DMSO-treated group; TPA, DMBA/TPA-treated group; SKN, shikonin-treated group; SKN+TPA, shikonin plus DMBA/TPA-treated group. *, p<0.05 compared with the DMSO Group; #, p<0.05 compared with the TPA group.
