PRC1 overexpression indicated an unfavorable prognosis in lung SCC patients. (A) IHC staining of high expression (down) and low expression (up) PRC1 in lung SCC tissues (×200); (B) Kaplan-Meier curves indicating the OS rate in 75 patients with lung SCC according to the expression status of PRC1. The median staining score served as a cutoff for high and low PRC1 expression. High level of PRC1 protein expression correlated with significantly poor OS. PRC1, protein regulator of cytokinesis-1; SCC, squamous cell carcinoma; IHC, immunohistochemistry; OS, overall survival.
