Epigenetics and Expression of the Wnt Signaling Pathway in Ulcerative Colitis

Zuhal Altintas | Mehmet Emin Erdal | Engin Altintas

Background/Aims: Secreted frizzled-related proteins (SFRPs) are antagonists that bind Wnt and inhibit signaling through this pathway. Secreted frizzled-related proteins are silenced by promoter methylation and cause hyperactivation of the Wnt pathway. In this study, the aim was to evaluate the relationship between methylation and expression of genes involved in the Wnt signaling pathway and the risk of cancer development in inflammatory bowel disease. Materials and Methods: The patient group consisted of 20 individuals who were diagnosed with left-side ulcerative colitis and under went surveillance colonoscopy; the control group consisted of 15 individuals without symptoms and endoscopic pathology who were screened for colorectal cancer. Tissue samples were obtained from inflamed and ...
