PRC1 is upregulated in primary lung PRC1 tissues. (A) PRC1 protein levels in TMAs (six paired lung SCC tissues and adjacent normal lung tissues) were measure with IHC (×10); (B) representative examples of PRC1 staining in lung SCC tissues and normal lung tissues are represented. The right panel indicated the quantitative analysis of relative expression density (×200). ***, P<0.005. PRC1, protein regulator of cytokinesis-1; SCC, squamous cell carcinoma; TMAs, tissue microarrays; IHC, immunohistochemistry.
