Fig. 6. High NFIB expression is correlated with advanced TNM stage and poor prognosis of CRC patients.

Fig. 6

a The NFIB expression was determined by IHC in CRC tissue and adjacent normal tissues (n = 261). Representative IHC images of normal mucosa, negative, weak, moderate, and strong NFIB expression are shown. b IHC scores showed overexpression of NFIB in CRC compared with normal colorectal tissues (p < 0.001). c NFIB expression level increased with the TNM stage (p = 0.042). d, e OS and DFS curves of patients with low NFIB protein expression (n = 91) and those with high NFIB protein expression (n = 97). High NFIB expression is associated with poor prognosis (p = 0.0355). f, g OS and DFS curves of patients with high NFIB and NAMPT protein expression. High NFIB and NAMPT levels are associated with poor prognosis (n = 188). Scale bar: 200 μm. IHC immunohistochemical, OS overall survival, DFS disease-free survival. Bar graph data are presented as the mean ± SD; ***P < 0.001.
