| الوصف: | UNC5C is a member of the UNC5H family of transmembrane receptors and functions as a dependence receptor. The expression of UNC5C is lost or markedly reduced in a large proportion of cancers at the messenger RNA level . However, there is little information available regarding the protein expression of UNC5C, the relationship between UNC5C protein expression and UNC5C methylation, and the correlation between patient clinical features and UNC5C protein expression in colorectal cancer. In this study, the methylation and protein expression of UNC5C were examined in 36 adenomatous polyps, 73 colorectal cancers, and 28 corresponding normal mucosa, and the correlation between the methylation, as well as protein expression status, and the clinicopathologic features was evaluated. Furthermore, the relationship between the methylation and protein expression of UNC5C, and correlation between UNC5C protein expression and overall survival were analyzed. The results showed that aberrant methylation of UNC5C was observed in colorectal cancers (78%) and adenomatous polyps (64%). The methylation-specific polymerase chain reaction results were confirmed by bisulfite sequencing of UNC5C promoter region. UNC5C methylation was significantly higher in early tumor, node, metastasis stage (I + II) of colorectal cancers. Compared with the corresponding normal tissues, protein expression of UNC5C was significantly lower in colorectal cancers (42%) and adenomatous polyps (81%). Protein expression of UNC5C was significantly higher in early tumor, node, metastasis stage (I + II) of colorectal cancers compared with advanced tumor, node, metastasis stage. Furthermore, patients with UNC5C-negative expression had a poorer prognosis than those with UNC5C-positive expression through Kaplan–Meier survival analysis ( p = 0.038), univariate ( p = 0.044) and multivariate analysis ( p = 0.045). According to Spearman rank correlation analysis, UNC5C methylation and protein expression were negatively correlated ( r = −0.461, p |
