GPR87 and familial pancreatic carcinoma: As shown in Fig. 6, GPR87 levels were positively correlated with nuclear p65 expression (r = 0.709, p = 0.022) and the mRNA expression levels of NF-κB downstream genes, Bcl-xL (r = 0.660, p = 0.038), CCND1 (r = 0.763, p = 0.010) and VEGF-C (r = 0.687, p = 0.028) in ten freshly collected clinical pancreatic cancer samples.
