WDR1 and neoplasm: Finally, by analysis of an independent cohort of PDAC tissue microarrays containing 81 PDAC and 44 adjacent non-tumour tissues, we showed that there was a significant difference in the protein levels of WDR1 in all the pairwise comparisons of the three groups (PDAC tissues with low TNM stage, PDAC tissues with high TNM stage and adjacent non-tumour tissues) (Fig. 2e).
