1 Predominant p53 G-->A transition mutation and enhanced cell proliferation in uterine sarcomas of CBA mice treated with 1,2-dimethylhydrazine. 1,2-Dimethylhydrazine transformation related protein 53, pseudogene Mus musculus
2 There was 100% correlation between p53 protein immunopositivity and subsequent detection of p53 mutations in DMH-induced malignant fibrous histiocytomas. Dimethylhydrazines transformation related protein 53, pseudogene Mus musculus
3 There was 100% correlation between p53 protein immunopositivity and subsequent detection of p53 mutations in DMH-induced malignant fibrous histiocytomas. Dimethylhydrazines transformation related protein 53, pseudogene Mus musculus
4 DMH-induced uterine MFH with p53 mutations also had a higher proliferative rate (qualitatively evaluated by immunohistochemical detection of proliferating cell nuclear antigen) when compared with other DMH-induced sarcomas. Dimethylhydrazines transformation related protein 53, pseudogene Mus musculus
5 Our data suggest that DMH-induced uterine sarcomas are not consistent with smooth muscle cell origin and that a subset of these tumors, specifically DMH-induced malignant fibrous histiocytomas, have unique p53 G:C-->A:T transitions and a high proliferative rate. Dimethylhydrazines transformation related protein 53, pseudogene Mus musculus
