SOD1 and cervical squamous intraepithelial neoplasia: By using VlnPlot, the Sod1 expression between fibrotic and con kidney was shown, and compared with the donor sample, we can see an obvious decrease in Sod1 mRNA level within PT of the CIN sample (Fig. 3H), while in mouse kidney, the decreased Sod1 mRNA level can be found in PT subclusters (PT S2/3) of uuo comparing with those of con (Fig. 3I).
