Research Summary

I am interested in the genetic pathways that lead to carcinogenesis in the digestive tract. FLI1, a transcription factor with a tumorigenic role in Ewing’s sarcoma, has been shown to be downregulated in gastric cancers, suggesting a possible tumor suppressor role. My current research is investigating the role of FLI1 in gastric adenocarcinomas by analyzing both primary human tumors and established gastric cancer cell lines.
