Correlations between NSUN6 expression and the clinicopathologic features of PC patients. (a–b) The comparison of mRNA expression of NSUN6 in PC tissue at different TNM stages from TCGA database and verification cohort 1. (c) Univariate and multivariate analysis of the associations between NSUN6 protein levels and the clinicopathologic features of PC patients from verification cohort 2 combined 3. Red lines represent clinicopathologic features significantly related with NSUN6. P < 0.05. (d) Correlation analysis between the NSUN6 and MKI67 mRNA expression from the 4 GEO databases, TCGA database, and verification cohort 1. *P < 0.05, **P < 0.01; n.s, not significant; Student's t test.
