Objective To investigate the effects of somatostatin on the apoptosis of colorectal cancer cells. Methods The expression of somatostatin mRNA in colorectal cancer tissues from 79 patients who had been admired to Yijishan Hospital from January 2004 to October 2006 was detected by nested RT-PCR. The apoptotic index of colorectal cancer cells was detected by TUNEL, and the protein expressions of somatostatin, Fas, FasL, caspase-3 and caspase-8 in colorectal cancer tissues were detected by immunohistochemistry. All data were analyzed by chi-square test, q test and Spearman rank correlation coefficient. Results There was a positive correlation between the mRNA and protein expression of somatostatin (r = 0.98, P < 0.05). The mRNA and protein expression of somatostatin in poorly and moderately differentiated colorectal cancers were significantly lower than that in well differentiated colorectal cancers (χ~2 = 10.78, 11.24, 5.27, 5.24, P < 0.05). The positive expression rates of mRNA and protein of somatostatin in papillary adenocarcinoma were significantly higher than those in mucinous adenocarcinoma and signet ring cell carcinoma and undifferentiated carcinoma (χ~2= 6.56, 6.99, 5.44, 7.39, P < 0.05). The mRNA and protein expression of somatostatin in colorectal cancer in Dukes A and B were significantly higher than that in Dukes C and D (χ~2 =5.17, 4.06, P <0.05). The apoptotic index in high or moderate somatostatin expression group was significantly higher than that in low somatostain expression group (q = 5.66, 4.21, P < 0.05), and the positive expression rates of Fas, caspase-8 and caspase-3 in high or moderate somatostatin expression group were significantly higher than those in low somatostafin expression group (χ~2= 5.48, 5.62, 6.89, 4.32, 4.19, 3.91, P <0.05). Conclusion Somatostatin plays an important role in the regulation of cell apoptosis in colorectal cancer, and the mechanism may be related to the aberrant expression of Fas/FasL.
