内容記述 | Villin1 (VIL1), a major structural component of the brush border cytoskeleton, binds actin in a calcium-dependent manner and has been reported as a marker for colon cancers. VIL1 was recently found to be an epithelial cell-specific anti-apoptotic protein and to have an important function in regulating actin dynamics, cell morphology, epithelial-to-mesenchymal transition, cell migration and cell survival. \nPurpose: We investigated a novel molecular biomarker for cervical adenocarcinoma (AD) through the integration of multiple methods of genomic analysis. Materials and Methods: Tumor samples in discovery set were obtained from 87 patients who underwent radiotherapy, including 31 cervical AD. Microarray analysis and quantitative polymerase chain reaction analysis were performed to screen a candidate diagnostic molecule for cervical AD, and its clinical significance was investigated by immunohistochemical analysis (IHC). Results: We analyzed the expression profiles of genes mapping to common deletious region in cervical cancer, and identified several consistently down-regulated genes, including ERBB4, VIL1, and DES in squamous cell carcinoma (SCC). Furthermore, we found a difference between biopsy samples of AD and SCC in the expression and genomic copy number of VIL1, which maps to 2q35. IHC revealed 14 VIL1-positive tumors; 13 cervical AD and 1 small cell carcinoma of cervix, while none of SCC or endometrial AD was VIL1-positive. The marker was validated by newly enrolled 65 patients, and VIL1 positive staining showed 52% of sensitivity and 100% of selectivity for cervical AD. In conclusion, we have identified VIL1 as a novel biomarker of cervical AD. |
