Growth Factor-Independent 1 Is a Tumor Suppressor Gene in Colorectal Cancer.

ABSTRACT: Colorectal cancer is the third most common cancer and the third leading cause of cancer death in the United States. Growth factor-independent 1 (GFI1) is a zinc finger transcriptional repressor responsible for controlling secretory cell differentiation in the small intestine and colon. GFI1 plays a significant role in the development of human malignancies, including leukemia, lung cancer, and prostate cancer. However, the role of GFI1 in colorectal cancer progression is largely unknown. Our results demonstrate that RNA and protein expression of GFI1 are reduced in advanced-stage nonmucinous colorectal cancer. Subcutaneous tumor xenograft models demonstrated that the reexpression of GFI1 in 4 different human colorectal cancer cell lines inhibits tumor growth. To further investigate the role
