摘要

Aberrant promoter methylation of CpG islands of tumor suppressor genes inhibits expression of the genes and may lead to tumorigenesis. We investigated the aberrant methylation profile of potential tumor suppressor genes of p15, p16, SOCS-1, and Wnt signaling pathway in colorectal cancers and correlated the data with clinical findings. Cancerous and nearby non-cancerous tissues of 185 sporadic colorectal cancer samples were studied. Methylation specific PCR was performed to explore the mechanism of inactivation in p15, p16, SOCS-1, E-cadherin, APC, GSK-3β, and Axin1 genes. Aberrant promoter methylation in p15, p16, SOCS-1, E-cadherin, APC, GSK-3β, and Axin1 genes were 5.9, 7.0, 3.8, 5.9, 12.4, 2.2, and 0% for cancerous tissues, respectively, whereas the frequencies were 3.8, 0, 0, 7.0, 2.7, 0.5, and 0% for nearby non-cancerous tissues, respectively. The frequency of aberrant promoter methylation of cancerous tissues was significant higher than non-cancerous tissues in p16, SOCS-1, and APC genes (p
