SSTR2 and hepatocellular carcinoma: None of several subtype specific SA [L-797,591 (SSTR1 agonist), L-779,976 (SSTR2 agonist), L-796,778 (SSTR3 agonist), L-803,087 (SSTR4 agonist), and L-817,818 (SSTR5 agonist)] affected proliferation or apoptosis in two human HCC cell lines (HepG2 and HuH-7), but L-797,591 inhibited the migration of HepG2 and HuH-7 cells in the presence of chemotactic stimuli[27].
