Figure 5From: Analysis of serum exosomal microRNAs and clinicopathologic features of patients with pancreatic adenocarcinomaRelative expression level of circulating miR-21 in each group. On the basis of RT-PCR assay of miR-21, there were 1.23-, 1.28- and 1.13-fold changes between the different stage, differentiation and metastasis groups of PC patients (P = 0.339, 0.385 and 0.668, respectively), indicating no significant correlations with stage, differentiation or metastasis.Back to article page
