... receptor density and a profound decrease of somatostatin receptor density in the mucosal ulcer margin and scar. These changes in growth factors and their receptors cause a strong increase of cell proliferation in the ulcer margin. In experimental ulcer models, EGF and basic fibroblast growth factor (bFGF...

... of human tumors demonstrate somatostatin receptors. All subtypes bind human somatostatin with high affinity, while somatostatin analogues bind with high affinity to somatostatin receptor subtype 2 (sst2). We investigated the sst2 expression in HCC and examined whether HCCs expressing sst2 are a distinct...
