1 Immunoblotting revealed that the levels of p53 and p21(WAF1/CIP1) in TAM-treated cells increased in a time- and dose-dependent manner, whereas those of p27(KIP1) and p16 slightly increased or remained unchanged. Tamoxifen tumor protein p53 Homo sapiens
2 These results suggest that the tumorigenic effect of TAM on MCF-7 cells arises through antitumor effects that are due to the expression of cyclin-dependent kinase inhibitors, especially p21(WAF1/CIP1) and these are regulated by the decrease of wild-type p53.
