Additional file 1 : Supplementary Fig.S1. Correlation between mRNA and protein expression of ROR1 and ROR2 in CPTAC PDAC discovery cohort. A. ROR1 mRNA and protein expression was positively correlated (Pearson’s R=0.25, p=0.005). B. ROR2 mRNA and protein expression was positively correlated (Pearson’s R=0.48, p<0.001)
