| Research Abstract |
In order to identify possible predictive markers, We performed the identification of miRNA related to the degree of differentiation-grade and malignancy by the profiling of esophageal cancer cell lines and esophageal cancer clinical specimens. In poorly differentiated cells, miR-29a and let-7b were overexpressed. We identified target genes of these miRNAs using in vitro pull-down method, and found some candidates of target genes related to tumor suppressor and apoptosis. Our results suggest that these miRNAs are involved in esophageal cancer progression.
