Cdkn1a, which encodes p21, functions as a major route for p53-mediated cell-cycle arrest. However, the consequence ofCdkn1agene dosage on tumor suppression has not been systematically investigated. Here, we employed BAC transgenesis to generate aCdkn1aSUPERmouse, which harbors an additionalCdkn1aallele within its natural genomic context. We show that these mice display enhanced cell-cycle arrest and reduced apoptosis in response to genotoxic stress. Furthermore, using a chemically induced skin cancer model and an autochthonousKras-driven lung adenocarcinoma model, we show thatCdkn1aSUPERmice display a cancer protection phenotype that is indistinguishable from that observed inTp53SUPERanimals. Moreover, we demonstrate thatTp53andCdkn1acooperate in mediating cancer resistance, using a chemically induced fibrosarcoma model. Overall, ourCdkn1aSUPERallele enabled us to assess the contribution ofCdkn1atoTp53-mediated tumor suppression.
