1 Increased expression of p53 and p21 (Waf1/Cip1) in the lesional skin of bleomycin-induced scleroderma. Bleomycin transformation related protein 53, pseudogene Mus musculus
2 In this study, we examined the induction of apoptosis and the expression of p53, p21 (Waf1/Cip1), and proliferating cell nuclear antigen (PCNA) in the lesional skin following bleomycin exposure in this model. Bleomycin transformation related protein 53, pseudogene Mus musculus
3 Immunohistochemical examination showed increased expression of p53 and p21 mainly in the infiltrating mononuclear cells at 2 weeks after bleomycin treatment. Bleomycin transformation related protein 53, pseudogene Mus musculus
4 Reverse transcriptase-polymerase chain reaction analysis showed that the expression of p53 and p21 mRNA was concurrently upregulated at 1-2 weeks after bleomycin treatment. Bleomycin transformation related protein 53, pseudogene Mus musculus
5 Our findings suggest that apoptotic processes are involved in the pathophysiology of bleomycin-induced scleroderma, which may be mediated, in part, by the upregulation of p53 and p21. Bleomycin transformation related protein 53, pseudogene Mus musculus
