(b) Semiquantitative analysis of ZEB1 in paratumor and tumor tissues. (c) Semiquantitative analysis of ZEB1 in CRC tissues with different T stages. (d) Semiquantitative analysis of ZEB1 in CRC tissues with different N stages. (e) Semiquantitative analysis of ZEB1 in CRC tissues with different M stages. (f) Semiquantitative analysis of ZEB1 in CRC tissues with different TNM clinical stages. (g) Representative images uncovering low and high ZEB1 and PD-L1 expressions in CRC tissues using anti-ZEB1 and anti-PD-L1 staining. (h) Correlation between ZEB1 and PD-L1 expressions in CRC tissues.
