Human SW480 colonic cancer cell line was evaluated for its growth response to Octa peptide somatostatin (SMS 201·995, SMS) in vitro by MTT assay and flow cytometry. The results showed that SMS possessed an inhibitive effect on SW480 cell at dose 1.563-200ng/ml, the maximal effective dose was 50ng/ml. Inhibitive effect of SMS did not steadily increase at a dose >50ng/ml. It suggests that effect of SMS is achieved via somatotatin receptor. SMS obviously inhibited the synthesis of DNA and protein, and prohibited the SW480 cell shifting from phase G0/G1 in phase S, G2M, which suggests that somatostatin (SS) possessed an inhibitive effect on large intestinal at cancer cell, it is achieved at receptor by inhibiting the synthesis of DNA and protein and prohibiting cell cycle of cancer.
