Fig. 7: PD-L1 is positively correlated with WIP expression in lung adenocarcinoma tissues and predicts poor prognosis in patients.

a PD-L1 and WIP expression of six human patient tissues and paired adjacent tissues was detected by Western blot. b PD-L1 and WIP expression from human lung adenocarcinoma tissue microarray of three cases with tumor and paired adjacent tissues was analyzed by immunostaining analysis. The representative images are shown. Scale bars = 100 μm. Original magnification: ×40. c The correlation between the expression of PD-L1 and WIP in human lung cancer tissues from 92 patients. d The relationship between the level of PD-L1 or WIP expression and clinicopathologic characteristics. e, f The relation between overall survival and expression of PD-L1 (p = 0.017) or WIP (p = 0.008) was analyzed by Kaplan–Meier analysis.
